Learn How to Clean a MixMaster Gun at World of Concrete 2020

The MixMaster Pro slab lifting gun was designed based on years of feedback from slab lifting contractors working in the field. Every known point of frustration and difficulty has been addressed in this sturdy, single-purpose gun. Further benefits include a lower cost of consumables (you can reuse ports with this gun), beefy check valves designed to handle the back pressure, and a short 10-minutes or less breakdown/cleaning session at the end of each day.

This gun is also is a production BEAST - no leaky port connections, no fumbling with clamps. Watch your man hours on each project shrink accordingly. Did we mention you’ll have less replacement part orders? There are only a few inexpensive replacement parts on this gun - PERIOD.

Ask about the quick 10-minutes or less breakdown/cleaning session on the MixMaster Pro at our World of Concrete 2020!  Drop by to see us at our Geotech Exhibit Space - # O40551 in the Silver Lots (same location we were in last year). 

There will be a LOT to see and do at our Geotech space this year:

How to Avoid Using More Lifting Foam Than Estimated

Posted by Andy Powell on Jan 7, 2020 4:35:54 PM

How to Avoid Using More Lifting Foam Than Estimated

How to Avoid Using More Lifting Foam Than EstimatedEvery once in a while, we will get a call from a frustrated contractor who has had a few jobs in a row where they used more foam than estimated.  Extra foam also means extra time on the job site so it's a serious concern with financial consequences.  

Although it's easy to think it might be the polyurethane not working right, that's usually not the case because formulations generally remain unchanged year after year.  Once a certain formula is dialed in and has gone through various approvals; it is unlikely to be changed.  So, what could be happening?

Site Evaluation Issues

I have been on more than a few jobs where the operator runs into a problem because the salesperson has missed something.  In cases where more foam than predicted is used it is usually because there is a big void that was not initially identified or there is very poor soil compaction.

When doing a proper site evaluation, you should start with bringing the right tools.  Bring a golf club or a piece of rebar to tap on the concrete and listen for voids.  Concrete makes a distinctly different "hollow" sound when there is a void beneath it.  Tap around the area to determine the extent of the void and then take measurements.  

I also like to have a cordless hammer drill with a 3/8" bit and a 1/2" bit.  If the customer will give you permission, ask to drill a small hole through the slab to check the void.  Make a mark on your drill bit when you break through the slab so you can determine the thickness of the slab.  Then I like to use a fiberglass driveway marker to stick through the hole and measure the amount of void.  If my drill bit is breaking through at 4" and my driveway marker goes in 7" before contacting the ground, then I know I have a 3" void.  When in contact with the ground, try to push the probe further into the ground to get an idea of compaction. If you can bury the probe by hand, then you know the ground is super soft or saturated and you need to account for more foam being used.

If you bring a borescope camera, you can drill a 1/2" hole in the slab and then insert the camera to have a look.  A good borescope will allow you to turn the camera head 90 degrees to have a look under the slab in a horizontal position.  These cameras plug into your smart phone or tablet so you can record video or take still shots.  This can be very compelling evidence to show a property owner and it also indicates that you know what you're doing.

So, what if you have all the cameras and probes, and you know how to sound out a piece of concrete with your piece of rebar; does that guarantee you won't go over on foam usage?  The answer to that is "No" because you may know how to check for a void, but you may not know where to check.  

Take, for example, a driveway slab that is down 2" from the garage slab.  It's easy for a salesperson to come out and measure the driveway slab, check for voids, and put together an estimate.  The experienced salesperson will also ask to go in the garage or carport to check for voids under that slab.  Polyurethane foam always tries to find the easiest path to travel when it is expanding.  If there is a washout under the driveway caused by a misplaced downspout; there is a good chance the void continues up under the garage as well.  Check the garage slab for cracking and tap on it with steel to listen for voids.  The point is to not get so focused on the obvious and take a look at the bigger picture.

Foam Issues

As I mentioned earlier, it's typically not going to be an issue with the foam unless you are using the wrong foam or sub-par foam in the first place.  However, you can still make a poor-quality finished foam with perfectly good raw materials and that will definitely affect the yield and the amount of foam that you will use on a job.  

Because Alchemy-Spetec does not use recycled materials in our formulations, the B-side is almost clear in color and the A side is always the color of weak coffee.  A quick test shot of our foam will let you know right away if it's on ratio because it will be a nice off-white color with a smooth skin forming as it expands.  If there is too much A side the foam will look more yellow and the texture will be crunchy.  If there is too much B side the foam will be pale white and soft.  It will take longer to cure and, in both cases, it will take more product to get the job done.

Besides doing an occasional test shot to check for color and foam curing speed, it's also important to watch the pressure gauges on the machine to make sure they are equal.  Also make note if you are going through a drum set and you consistently have too much A or too much B left over while the other drum is empty.  It could be an adjustment needs to be made at the machine itself.

The PolyBadger Lifting System: Tough and Compact

Posted by Andy Powell on Nov 21, 2019 1:05:31 PM

The PolyBadger Lifting System_ Tough and Compact

The Polybadger Lifting System_ Tough and CompactThe Alchemy-Spetec PolyBadger mobile slab lifting system (named in honor of the mighty honey badger) is tough and compact. 

The Polybadger is Tough

The PolyBadger slab lifting system is built to last:

  • The cabinet is constructed from powder coated carbon steel and the frame is constructed from carbon steel box tubing. 
  • The durable hose is constructed with a Teflon core and a stainless-steel braid. (The system can operate with up to 200 feet of hose.)
  • Essential elements (heaters, electronics, auto calibrator) are self-contained and protected in a metal cabinet.

The PolyBadger is Compact

The PolyBadger slab lifting system is durably built and designed to go where other lifting systems simply cannot venture:

  • The PolyBadger is smaller in size than most of the competition, at 30" wide and 48" long. Now that's what you call portable!
  • This is one of the few systems powered through a common 120-volt wall outlet (vs the usual 240-volt requirement). Compatibility with common wall outlets exponentially increases your location possibilities.
  • The entire system is very maneuverable, resting on two swivel and two fixed 6-inch pneumatic castor wheels.  The wheels are are filled with light weight polyurethane instead of air, so they don't go flat. 

The Auto Calibrator

Another essential feature is the auto calibrator. It keeps the flow of A-side and B-side slab lifting material on ratio, eliminating the possibility of crossover clogging in the gun or the whip hose. The two low-pressure transfer pumps and auto calibrator are literally the only moving parts in the whole system. That means less downtime, less maintenance, and more productivity on the job. This system is easier to use and a more affordable than many options on the market.

Slab Lifting and Leak Sealing in Cold Weather

Posted by Andy Powell on Nov 1, 2019 10:53:58 AM

Slab Lifting and Leak Sealing in Cold Weather

Slab Lifting and Leak Sealing in Cold WeatherSlab Lifting in Cold Weather

Contrary to popular opinion, as a contractor, you don’t have to put up your equipment and rigs due to cold weather. There are many jobs to be done and many ways to keep your material conditioned. Use this season to your advantage and gain valuable business.

Seasonal attractions such as theme parks, for example, are a great place to start looking for winter work. Many of these parks (the ones that aren’t in Orlando) shut down for the winter and this is the time they do maintenance and repairs. Think of all the concrete lifting and leveling that can be done.

Read all about cold weather slab lifting markets, conditioning materials and more in our blog post Slab Lifting in Cold Weather.

Leak Sealing in Cold Weather

You have a variety of options for seeking leak seal jobs that are inside, out of the elements, during the winter months. (See the linked article below for a list of ideas.) If you’re still up for working outside during the winter months, you’re in luck because concrete contracts during colder weather. The contraction makes cracks open wider (thus easier to seal). One important point to understand is that cold weather requires you to make an extra effort to keep your materials and equipment warm.

Reparing Dangerous Sunken Slabs in Warehouses and Factories

Posted by Andy Powell on Oct 29, 2019 4:25:03 PM

Reparing Dangerous Sunken Slabs in Warehouses and Factories

Reparing Dangerous Sunken Slabs in Warehouses and FactoriesSafety is the number one priority for factory and warehouse managers across the country.  Emphasis is most often placed on training employees to wear the right personal protective equipment and observe safety procedures when operating machinery - and rightly so!  In addition, it's also important for management to consider the state of the concrete slab floors.  Sunken or rocking slabs can cause trip hazards and damage equipment.  Undetected voids underneath seemingly solid slabs create the risk of sudden collapse.

Alchemy-Spetec sells high-strength polyurethane resin to slab repair contractors all over North America.  We can help you find a well-trained contactor to inspect the concrete in your warehouse or factory.
