Body-Sealing Gushing Leaks with Oakum Soakum

AP Oakum is an oil-free dry jute rope which can be used dry or soaked with Spetec PUR GT500, Spetec PUR F400 or any other Spetec water-reactive resin to seal leaks in concrete structures. It works well dry to drive into cracks as a temporary seal to allow injected resin time to cure without washing out. Here’s an overview of the installation process:

Preliminary Analysis

Determine if the large crack or joint is structural or cosmetic. If deemed structural, consult an appropriate engineer. Oakum is typically utilized in conjunction with water-reactive chemical grouts in leak-sealing applications. Void filling of these spaces can also be achieved through similar application techniques and appropriate product selection.

Preparation of Substrate

Remove all existing sealant, debris, or contamination of any kind. In large openings, inspect for loose concrete or anything that would prevent insertion of Oakum into the desired depth and location.

Preparation of Product

Firstly, cut oakum into desired lengths and segments. Pre-mix hydrophobic or hydrophilic chemical grouts per manufacturer recommendation in a separate container taking note of working times and reaction times. Once the material is mixed, quickly, and fully soak the Oakum in the mixed chemical grout. Place the saturated Oakum to the desired location.

Preparation of Personal Protection Equipment

Oakum is typically manually installed. Be sure to wear full hands, arm, face, and eye covering at
all times. Chemical grout can drip/spill cover anything with which it comes in contact.

Application

  1. Clean the surfaces to which the oakum will be applied. Wet the surfaces down if necessary, to react with the resin.
  2. If necessary, cut the oakum into appropriate lengths.
  3. Place oakum in a clean container (5 gallon/18.9 liter pail or plastic bag) and saturate with resin. Allow time for the resin to soak into the oakum.
  4. Using gloved hands, pull a section of oakum through a loose set to wring excess resin from the oakum.
  5. Optional Step: Dip the oakum into a pail of water to begin the reaction process. This will begin the reaction process of the resin. This step causes the resin to begin to expand.
  6. Pack oakum into the joint, crack, or other defect using a screwdriver, wooden dowel, or other mechanical device sized appropriately for the joint, crack or defect.
  7. After the resin has cured you may inject additional resin through a grout needle directly through the oakum or by drilling holes through the concrete behind the oakum.
  8. Allow the material to cure overnight before attempting to trim the excess foam.

Polyurethane Crack and Curtain Grouting Demo

Posted by Charlie Lerman on May 5, 2020 10:00:00 AM

Banner-Crack and Curtain Demo

Body-Crack and Curtain DemoEmbedded below is a crack and curtain grouting video demo I recently recorded.  For those not familiar with me, my name is Charlie Lerman. I'm the Director of Technical Services for the Leak Seal Division at Alchemy-Spetec (and I'm also known as the Grout Geek). I have been involved in a wide variety of grouting jobs from dams to tunneling, municipal to sewer system work, residential, commercial, and industrial.

Prior to joining the Alchemy-Spetec team, I was with the Navy in the submarine and recruiting services. I have 20 years of construction experience – I was with a restoration contractor for five of those twenty years and earned a bachelor degree in Business Management during that time. I have been providing technical support and training for polyurethane grouts for over fifteen years and have been involved with the International Concrete Repair Institute (ICRI) for a decade.

Social distancing does not have to mean downtime. This is an excellent time to learn about polyurethane chemical grouting. From my home "studio" I bring to your home office demonstrations on crack injection, curtain grouting, and pump operation/maintenance.

Posted by Michael Binyaminov on Apr 16, 2020 10:00:00 AM

Banner-Develop Your Competitive Edge

Body-Develop Your Competitive EdgeWhenever I talk to contractors who are in the market for a polyurethane materials provider, I always find myself discussing the same set of important points.  In a nutshell, I end up sharing my appreciation for the unique ways in which we can help contractors develop a competitive edge. In order to make this info available to a wider audience, I've decided to write it all up in a brief blog post.

Polyurethane – Quality and Selection

Alchemy-Spetec offers one of the most technologically advanced grout product lines currently on the market, including our unique, highly-effective Spetec PUR HighFoamer. Known in the industry for its expansive properties, this product is the only one in its class that can shut down gushing leaks and fill voids as quickly and effectively as it does. We offer a wide variety of materials, including slab lifting foams, deep-soil lifting foams, soil stabilization foams, injection resins for crack leak seal, foams for curtain grouting leak seal, acrylic injection resins that penetrate thin cracks and saturate soil, epoxy resins for structural repair and preventative waterstop products. The superior quality of these materials guarantees fewer callbacks from your customers. Many of these products are also certified for contact with potable water, making them safer for the environment.

For example, our team was recently called on to assist with a large metro project in the Western United States. The customer informed us at 4pm on Monday evening that assistance was needed at 9am the very next day! Our Technical Services Director Charlie Lerman, Vice President Jim Spiegel, and Western Regional Sales Manager (that's me!) traveled to the site Monday evening to help diagnose the location of the leaks and develop an action plan. Our Technical Services Manager Charlie remained on site for two more days to ensure that the project was successful. Depending on the size and scope of the project, response time and participating team members may vary, but this story serves to illustrate the lengths we will go to assist customers.

Training and Education

We offer the industry's most thorough training and education for both Leak Seal and Geotech polyurethane infrastructure repair. We conduct training workshops at distributor locations, consult with contractors on job sites, and hold intensive programs twice a year at our headquarters in Tucker, GA.

Case Study - Sealing Hairline Concrete Cracks with Acrylic Injection Resin

Posted by Charlie Lerman on Apr 7, 2020 10:00:00 AM

Banner Case Study - Sealing Hairline Concrete Cracks with Acrylic Injection Resin

Body Case Study - Sealing Hairline Concrete Cracks with Acrylic Injection ResinI'd like to share a case study from a job that I recently consulted on with one of our contractor customers.

A concrete tank west of Rollinsville, Colorado began showing numerous, hairline cracks during construction. Previous attempts to seal the cracks using urethane grouts were unsuccessful due to the sheer tightness of the cracks and high amount of reinforcing steel. The tank was critical for a state infrastructure project, so Restruction Corporation was called in to get the job done.

Powerful Polymer

After a phone consultation, we determined the best course of action would be to use Spetec AG200, a super-thin acrylate grout that could penetrate the hairline cracks and even the ones previously injected with a urethane grout. This water-swelling hydrogel is based on low-viscous acrylic that cures into an elastic product with 500% elongation.

Painless Procedure

I trained a knowledgeable polyurethane grout crew how to handle Spetec AG200 and an acrylic pump. No other chemical grout manufacturer was willing to come out and provide field service for this application.

Rapid Result

After the grout was injected, the cracks sealed quickly. Both the customer and contractor were extremely happy with the results. Yet another successful job for one of our customers!

Polyurethane Leak Seal for Basement Walls

Posted by John Ziebell on Mar 26, 2020 10:00:00 AM

Banner Graphic - Polyurethane Leak Seal for Basement Walls

Body Graphic - Polyurethane Leak Seal for Basement WallsToday’s guest blogger is John Ziebell, an independent representative of Alchemy-Spetec. Formerly the Vice President of Operations for Deneef Construction Chemicals, Inc., John has 36 years of experience in the chemical grout industry and is currently a member of the International Concrete Repair Institute (ICRI).

Recently, I visited a homeowner in Elkhart, Texas whose basement flooded after a heavy rainstorm. The house was three years old, and this was the first time water had entered the home. When we went into the basement, I saw that a water-repellent coating was applied to the below-grade walls during initial construction, but it was unclear if a water stop had been installed at the wall joint.

To test for the leak source, I suggested installing soaker hoses in the flower beds adjacent to the basement wall, flooding the beds for several hours, and confirming if water appears at the wall or floor joints. I also recommended two different options to prevent further leaks:

Option 1 – Polyurethane Crack Injection

If the cracks in the basement walls can be clearly identified and there aren’t too many of them, the contractor should use the polyurethane crack injection procedure. First, they’ll need to remove any surface contamination with a grinder. Then, they can drill holes spaced about 1 foot apart at a 45° angle to intersect the middle of the crack or joint and flush all of the injection holes with clean water until water runs from hole to hole. Once the water flow is confirmed, they can inject the crack or joint with Spetec PUR F400 (and GEN ACC Accelerator) until it’s completely full.

Option 2 – Polyurethane Curtain Wall Grouting

If cracks in the basement walls are difficult to identify the contractor should use the polyurethane curtain wall grouting procedure. First, they’ll need to remove any surface contamination with a grinder and drill holes in a diamond grid pattern (see photo included with this post). Then, beginning at the bottom of the wall, they can inject the holes with Spetec PUR H100 (and GEN ACC Accelerator) until they reach the top of the wall.

Many people ask if grouting only around the bottom next to the leaks is effective, but this is seldom the case. Grout is injected through the entire wall because any excess grout flows down over the previous injection area, creating a lapping effect like shingles on a roof.

Both options have their advantages depending on the situation: polyurethane crack injection is a cost-effective, pinpoint approach that is ideal for a small number of clearly identifiable cracks, while curtain wall grouting is a pricier approach that is ideal for a larger number of difficult to identify cracks.

Adam Tracy on How Long It Takes to Develop Field Competency for Leak Seal Grouting

Posted by Kreg Thornley on Mar 5, 2020 9:46:27 AM

Banner - Adam Tracy on How Long It Takes to Develop Field Competency for Leak Seal Grouting

Body - Adam Tracy on How Long It Takes to Develop Field Competency for Leak Seal GroutingThis article is an excerpt from Episode 4 of The Injection Connection, featuring Adam Tracy of A-1 Foundation Crack RepairThe Injection Connection is hosted by Jim Spiegel: Vice President of Alchemy-Spetec and Board Member at the International Concrete Repair Institute.  (If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim: Where do we find talent? That’s a big thing in our world especially being so niche of an application. How do you find talent? One of the things that we like to look at is, getting somebody with an engineering mind, such as yourself - engineering or architectural mind that just knows buildings and knows the X’s and O’s of the construction world and just get them on site, just to learn. We think that could be the one-two punch to really get good, competent people out there. You’re a perfect example of it. You come in with a very high level of understanding of the construction world and building in general and then couple that with some field training and you’re pretty lethal as far as your effectiveness in the field.

To that point, how long do you think it takes? Say somebody coming out of college: I have a bachelor’s in engineering, maybe I don’t want to work in an engineering firm, maybe I want to get into the sales side with the manufacturer building products. How long do you think it takes in field time with chemical grouting until you’re up and running and you really know the nuances of a lot of what happens out there?

Adam: That’s a tough question. I’ve used myself as a little bit of an example because while I’d been around it for a while because I had gone my own path for a period of time right out of school, it was kind of just there and didn’t really know much about it. Doing it every day, it was a good with my educational background being an engineer in the civil engineering space.  Knowing building and construction, it took me a good two, three months of every day (hands-on application to really understand the limitations, the successes, how it works, why it works, which product is going to be most successful, in which application) until I was comfortable being able to see the solution before I even put a drill to a wall. The fortunate thing is that I was able to rely on years of construction experience and being in these green builds whereas somebody who might be right out of school has never been on a site, has never thrown on the hardhat and the vest and walked around. So there’s a whole learning curve to that as well. But again, the field experience I think is critical in any industry. Especially as you get into more and more isolated niche industries, your opportunity to learn is few and far between on a study level. The field experience becomes your classroom.

When we bring people on, talking about finding good people, if we find somebody who has any experience in injection grouting, it’s a diamond, it’s a needle in a haystack so to speak. There’s a significant training curve on our end to bring talented people who have this construction experience to a level of being able to be proficient in the trade.

It’s a tough thing because everyone’s individual but the more time in the field, I think, is critical because, again, if you happened to be taught it in some educational level, it was a leap on the radar and it was quickly moved past as part of envelope education study whereas the actual time in the field really becomes your classroom, like I said.

Jim: Absolutely. It’s your point though or kind of to the point, two or three months was effectively your gut, visceral reaction there to time in the field. Compared to some other industries, that’s not all that long.

Adam: No but that was an everyday obligation.

Jim: Exactly. You take like a manufacturer rep for instance who might be on site once a month for a few hours to add that time up to be two months, constant trained would take years to become that well-versed.

Adam: In like anything. I’ve lived in that sales role as a manufacturer sales rep and while you may know the spec sheet of your product inside and out, that doesn’t tell you the whole story of the product that you’re going to use. It’s when it’s applied in the field whether it’s a pump or a truck or a crane or chemical grouting, it’s the performance in the real world beyond the spec sheet that tells you or completes a picture of your education on the product.

For those who are on the manufacturing side, the time in that field, actually doing the work I think is one of the most critical parts of it.

Jim: For sure. We liken it to a mechanic who can listen to an engine and give you a pretty good of what he’s up against. Very similar in the field, Charlie, who I mentioned, I think he’s been in the field services role for 15, 16 years as well and he can tell you what’s happening by the way the hose is jumping for instance on each stroke, and the sound of the stroke for instance. There’s a lot of that mechanic level field support that just isn’t that readily available in the chemical grouting world. We put Charlie in the field services director role because, and this is not intended to go into a sales pitch but just to your point that a lot of manufacturers are kind of shying away from the field support where you have to be out there seeing so many customers and making so many calls and it’s like a telemarketing solution sometimes for an industry that is so critical for accuracy in the field.

I agree with you completely. We actually tell our guys, you said you had experience on the sales side of it from manufacturer, and we tell all of our guys and girls – get in the field and spend time with the contractors. I still go out in the field. I was just on a job a couple of Fridays ago, we were doing polyacrylate gel injection. I was on the gun and I was saying to the technicians – you guys tell me, instruct me a little bit what you see out here because a couple of people who were out there had significant experience.

To your exact point, manufacturers can read spec sheets and tell you little nuances of performance from TDS but until you know what the gun feels like, the guys in the field are still probably head and shoulders above you.

Adam: Yeah, for sure. And it’s always tough to be in that role where you’re supposed to be the expert and asking for help. I’ve been in those situations, it’s always uncomfortable as being on the manufacturer side to say, "okay, what would you guys do here?"...you know, being the guy with 30 years of experience.

Adam Tracy on What Can Be Improved in the Chemical Grouting Industry

Posted by Kreg Thornley on Mar 3, 2020 3:20:58 PM

Banner - Adam Tracy on What Can Be Improved in the Chemical Grouting Industry

Body - Adam Tracy on What Can Be Improved in the Chemical Grouting IndustryThis article is an excerpt from Episode 4 of The Injection Connection, featuring Adam Tracy of A-1 Foundation Crack RepairThe Injection Connection is hosted by Jim Spiegel: Vice President of Alchemy-Spetec and Board Member at the International Concrete Repair Institute.  (If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim: In a more general sense with the chemical grouting industry, what do you think, and I may be putting you on the spot here a little bit, but what do you think is lacking or what could be improved in the industry? Do you have opinions on that? Maybe from a product standpoint, maybe from a service standpoint, from the manufacturer’s side? Do you have any thoughts on that?

Adam: I’ve had a pretty unique entry into this industry because I’m from totally outside of the industry. Even though this is a family business, I actually spent the first ten plus years of my career as a manufacturer rep in the fire protection space. So, I’m coming at this industry as a very different set of eyes. I’m actually an engineer in civil engineering and I would definitely say that it’s a niche industry in a lot of ways, which prevents its usage I think because I don’t think it’s well taught on an educational level and I don’t think the awareness is very high amongst a lot of engineering firms as well. 

It’s a process that is unique in a lot of ways but it’s not revolutionary. I think while it’s one tool in the tool belt as we discussed, I think having that in an engineer’s hands is very important because a lot of times solutions that are tried more often or may have a higher success rate on the positive side are just cost prohibitive. And the building is not set up to be able to do that kind of stuff post construction and where chemical grouting is really just the best, most cost-effective, high result solution for that particular application.

I would definitely say that on a commercial level the grouting process needs to have a little bit higher expansion in educational areas to make sure that kids coming out of schools and going in for their PEs and trying to get their feet under them and provide solutions to their clients know that this is a proper solution that is tried and true and is very successful.

In my world, where it’s a lot of residential, that’s half of what my job is on a day to day conversation with a customer is explaining what we’re doing because it’s a lot of black magic in their eyes because it’s something totally different. They were looking for the black spray in the can that you used to spray in the bottom of your screen door boat there, off the shelf as a solution and they‘re trying to figure out why it didn’t work. And really, we’re trying to just educate them a little bit as well.

We’ve had projects in the past where they’ve spent a tremendous amount of time on the specifications and the procedures on how to address an issue. We had a project at a wastewater treatment plant where it’s 24-inch walls, thick walls with rebar everywhere, and they were tall. And they’re just trying, there’s not a lot of experience, there wasn’t a lot of manufacturer help in terms of how to really identify the process to do this successfully. So, when we get in there and we look at the specifications, it’s hobbled together by somebody who’s never seen this process in the real world. It was essentially set up for failure in a lot of ways because the process was wrong for this particular application, and trying to go through change orders of the process was a very difficult situation - just because we knew as a contractor doing it for as long as we have that the amount of time and effort that they were going to be focused on their particular process was going to be set up incorrectly and set up for failure mostly because, again, they had a set of people on this thing who have read about it and were very unaware of the infield techniques that are required to be successful in it, and really just tried to be by the book on it without any sort of experience.

I think that in the industry, there would be a huge benefit across the board in my eyes to really start at the educational level, civil engineering programs, construction management programs, to really focus on that. I think manufacturers have some responsibility as well as contractors to give a two-pronged approach so that people are educated both on the technology itself and the actual application and how it gets done.

Jim: I couldn’t agree more.

Quantifying Chemical Grouting Effectiveness with The QP Factor

Posted by Jim Spiegel on Feb 13, 2020 3:24:16 PM

Quantifying Chemical Grouting Effectiveness

Quantifying Chemical Grouting EffectivenessThis blog post features Episode 2 of Alchemy-Spetec's The Injection Connection podcast.

This is a presentation given to an engineering firm regarding the new patented leak seal QA/QC system The QP Factor: the first patented method to quantify leak seal grouting and leak seal effectiveness.

As mentioned in our previous post on this system...

The method of testing requires additional drill holes to be placed at pre-determined locations along the crack, joint, or substrate being sealed. Prior to injection of chemical grouts such as Spetec PUR F400, Spetec PUR HighFoamer, or Spetec PUR GT500, the test hole is connected to a digital touch-screen device that is calibrated to provide water pressure, flow, and flow/pressure information that is extractable in excel format from a convenient USB port.  Following initial testing, the test port is then plugged during chemical grouting operations to avoid false-positive results after injection. 

The presentation was first unveiled at the International Concrete Repair Institute, National Convention in Jacksonville, Florida, in 2019. Due to the context, there may be some points that seem a little abstract to the average viewer. If you have questions or need more details, please call Alchemy-Spetec at 404-618-0438.
