Alchemy-Spetec Geotech Resources

Alchemy-Spetec Geotech ResourcesSinking slabs and soil issues can cause both safety and property value problems. Alchemy-Spetec offers solutions for unlevel concrete and unstable soil.

Concrete Leveling

A structure is only as good as the foundation it’s built on. And regardless of how well-constructed a structure may be, most foundations settle. That’s just a fact of life. Erosion, shifting soil, compaction, and many other environmental conditions tend to cause settling. Sometimes structures settle gradually, and in other cases they’re swallowed up in minutes. These situations create problems for property owners and opportunities for the contractors who know how to fix them.

Alchemy-Spetec manufactures high-strength polyurethane lifting foams for slab jacking. Among the most dependable products for jacking and leveling concrete slabs, these two-component, high-strength, hydro-insensitive structural foams serve as an extremely effective solution for contractors.

Deep Lift Structure Leveling

Poor compaction, water erosion, broken pipes, and organic material in the soil can all lead to
settling of a foundation or a roadway. Traditional slab lifting can bring concrete and structures
back into place but it doesn’t necessarily address the underlying issue or guarantee a long
term fix. Other methods of addressing deep soil issues require heavy equipment, extended
down time, and collateral property damage. These situations create problems for property
owners as well as opportunities for the elite contractors that know how to fix them.

Alchemy-Spetec offers a unique combination of high-strength polyurethane structural lifting foams along with the equipment and training needed to address deep soil issues. Now you can achieve soil densification and lifting on large projects with the smallest footprint and least amount of heavy equipment required.  The Deep Lift™ process is powerful, painless, and rapid. Deep Lift™ gets to the root of the problems in the soil, it brings the structure back to level, and accomplishes this with minimal imposition or downtime to the property owner.

Soil Stabilization

Unstable soil can be defined as soil that will not stay in place on its own, and therefore requires
extra support. It should be noted that unstable soil can threaten the stability, security,
and safety of infrastructure and can damage, degrade, and even destroy a number of structures,
such as buildings, bridges, and roads. There are a variety of factors that can cause unstable
soil including erosion, poor compaction, freeze/thaw cycles and decomposition.

Soil can be stabilized high strength polyurethane stabilization foams.  Once the bearing capacity of the
soil has been increased with this process, then the structure can be lifted if necessary.

Filling Abandoned Pipes with Spetec PUR H100

Posted by Anthony Sandone on May 15, 2019 3:39:12 PM

Filling Abandoned Pipes with Spetec PUR H100

Filling Abandoned Pipes with Spetec PUR H100I was recently contacted by an engineer in New England who requested a demo with one of our products.  Specifically, he wanted to test Spetec PUR H100 for filling abandoned pipes.  In this case, we tested the material on a 6-inch diameter PVC pipe (but any type of abandoned pipe can be filled with expansive polyurethane as long as it's 30 inches in diameter or less).  This pipe was 10 feet long, but there is no real length limit using the technique I describe in this blog post.

First, we plugged both ends of the pipe.  We drilled a hole in the top middle of the pipe and inserted a port.  We then injected the Spetec PUR H100.  For longer pipes, you would place a port every 3 feet or so.  You'll also want to drill one 3/8" vent hole per 10 feet of pipe, in between ports.  Of course, most abandoned pipes are located underground, so your crew will have to dig down to expose top of the pipe.

Alchemy-Spetec Leak Seal Resources

Posted by Charlie Lerman on May 10, 2019 3:53:49 PM

ALCHEMY-SPETEC LEAK SEAL  RESOURCES

ALCHEMY-SPETEC LEAK SEAL  RESOURCESLeaking concrete can be detrimental to safety and property values. The products offered by Alchemy-Spetec deliver the ultimate solution for hairline cracks, gushing leaks and other waterstop issues.

Sealing Leaks with Concrete Crack Injection

Concrete starts decaying immediately after it cures. Even brand new construction can require leak seal follow up work. Older concrete structures are even more susceptible. Leaks through concrete are generally going to be through cracks, joints, and honeycomb (areas in poured concrete of mainly course aggregate with voids in between). Depending on water volume and pressure, and the size of the joint or crack, you are going to encounter weeping leaks, steady leaks, and gushing leaks. These leaks can be sealed with crack injection resin.

Stopping Multiple Leaks with Curtain Wall Grouting

Curtain wall grouting is often required when cracks cannot be identified, when the walls are made of material that does not respond well to crack injection (such as masonry, stone and CMU), and when previous leak seal methods have failed.  Curtain wall grouting is the process of injecting water reactive resin behind the leaking wall in a grid pattern. The water on the other side mixes with the grout and cures to a solid mass covering
the surface of the wall on the other side.

Waterstop

Newly constructed floor/wall joints with no waterstop lining can be vulnerable to water infiltration. When designers and builders neglect to line the joints, water can seep into the structure and out onto the floor. Needless to say, water on the floor can be an inconvenience, it can be a safety hazard, and it can damage property. In addition, floor/wall joint leaks can cause the concrete to decay and spall over the long run. Alchemy-Spetec offers a variety of waterstop solutions.

US Department of the Interior Study Finds Spetec PUR F400 Effective in Sealing Contraction Joints

Posted by Jim Spiegel on May 8, 2019 4:17:13 PM

US Department of the Interior Study Finds Spetec PUR F400 Effective in Sealing Contraction Joints

The U.S. Department of the Interior and the Bureau of Reclamation recently conducted a study in which they evaluated methods for sealing contraction joints in dams. They tested 8 methods. Spetec PUR F400 was used in one of only two methods that reduced water flow 100%. We'll share some excerpts from their report in today's blog post...

The U.S. Department of the Interior protects America’s natural resources and heritage, honors our cultures and tribal communities, and supplies the energy to power our future. The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public. 

All Reclamation concrete dams have joints which experience pressure caused by the reservoir water elevation. These joints have waterstops between the formed drain and the upstream face of the dam to prevent water leakage through the joint. Over time, the waterstops can begin to leak which can become a significant maintenance issue. These leaks can lead to millions of dollars of increased maintenance costs across numerous facilities, since they corrode metalwork, increase operation costs through increased pumping to remove excess water, and reduce worker productivity as they work around the leaks, etc. In some cases, the water leaks can threaten or damage expensive equipment.

Conventional leaking contraction joint repair methods are either very expensive or do not last long. Based on work from previous years looking into cheaper repair options, where we developed an inexpensive method to deliver repair materials to a specific location deep under water, several prototype repair methods were developed. To test those methods, we built a laboratory fixture to simulate a leaking contraction joint in a dam under pressures as high as 35 psi. With this fixture we tested different repair options. These options included sawdust, hydrophilic waterstop chips, chemical grouts used for sealing water leakage through concrete, and combinations of the chips and grouts.

In this testing we found that sawdust didn’t slow the water flowing through the test fixture joint. Hydrophilic chips slowed the water by as much as 65%, and Hydrophilic chips combined with some chemical grouts completely stopped the water flow through the test fixture jointThese results could have substantial implications at Reclamation facilities with leaking contraction joints. These methods can be implemented to significantly reduce or completely stop the infiltration of water and are much cheaper than many alternatives.

Here is the product comparison table excerpted from the report...

Use the High Pressure F-Valve Assembly For Twin Streaming

Posted by Stephen C. Barton on May 6, 2019 3:01:22 PM

Use the High Pressure F-Valve Assembly For Twin Streaming

Use the High Pressure F-Valve Assembly For Twin StreamingWe've blogged about this before, but it's worth repeating. Twin streaming is a technique in which you use a high pressure 3,000 psi F-valve to inject resin AND water at the same time. As you can see in the photo, the F-valve has two supply connections - one for water and one for resin. The water and resin come into contact before they exit the coupler.

Advantages:

  1. Ensures there is enough water for the resin to react with.
  2. Starts the reaction immediately.
  3. Promotes faster reaction in cold water.

Filling Voids Above the Water Table

When working on jobs that require void filling behind walls, also known as curtain grouting, it is imperative that you are prepared for any obstacles that may occur. If the voids are large and dry, resin may not have enough water to react with when injected in the conventional manner. In this case injecting water behind the wall prior to injection might not be sufficient (especially if the void is open or filled with gravel, giving the water an easy path to escape). With twin streaming you are guaranteed there is enough water for the resin to fully react and fill the voids.

Injecting Resin Into Cold Water

Twin streaming also works well if you find yourself having to inject into a cold, underwater environment. You can inject warm water along with the resin to jump start the reaction process before the cold water gets a chance to slow down the process. The ratio of water to resin can be controlled by opening the valves at different angles. Some products such as Spetec PUR H100, Spetec PUR H200 and AP Fill 700 only need a little water to react with (10:1 resin to water is plenty). In this case, you would crack the water valve slightly, then open the resin valve all the way. Other products such as Spetec PUR GT500 and Spetec PUR GT350 need more water. A 2:1 or 1:1 ratio of resin to water both work well. In this case, you may want to open both valves all the way.

Working on Dams and Locks with Spetec Leak Seal Resins

Posted by Andy Powell on May 2, 2019 3:40:30 PM

Working on Dams and Locks with Spetec Leak Seal Resins

Working on Dams and Locks with Spetec Leak Seal ResinsIn a structure that holds water, you need something flexible to inject into cracks or joints. These types of structures are usually above ground and exposed to changing temperatures. As concrete heats up during the day it expands; joints and cracks squeeze together. As it cools, the concrete shrinks and joints and cracks open up. Thus, you need an injection foam that has flexibility to handle the movement.  You also need to do the injection work in the early hours of the day. Some contractors have injected cracks in the afternoon; stopping leaks, only to find them leaking again in the morning. 

For these scenarios, we recommend the Spetec PUR GT500 or Spetec PUR F400.  The GT500 is hydrophilic and absorbs some water during the reaction. In a tight crack or joint it's great and has minimal shrinkage if it dries out.  It has lower expansion, maybe 4-6x by volume, so for wide joints it may take more product and will likely require oakum to retain the resin in the joint. It does not have an adjustable set time. 

The F400 is a flexible hydrophobic. It combines higher expansion properties with flexibility. It also has a catalyst which allows you to adjust the set time. The F400 is excellent for crack injection, joint injection (especially larger joints), and infrastructure injection as well.  It does not shrink because it's hydrophobic and unaffected if no moisture is present. 

Now let’s talk a little about hydrostatic pressure. Most injection work is done less than 40' below the water level and head pressure is less than 20 psi. Considering we recommend injecting with pumps capable of 3000+ psi, getting the product in the crack is not the problem. The challenge is keeping the polyurethane in the crack or joint long enough for it to set up. That's where experience comes into play. The contractor must know how to adjust the set time, how to drill the injection holes properly, how to use oakum, and how long to inject on a single packer/port.   

We have not seen failures on dams or locks where pressure blew out the polyurethane. Dams across the globe have been injected this way. Where we do see failures (continued leaks, not blowouts) is when the wrong material is selected, or the injections are done during the hotter hours of the day. In fact, some water authorities only inject during the cold months of the year.
