It's that time of year again. As temperatures drop, take a moment to review this previously posted article packed with cold-weather tips.

There are plenty of leak seal jobs that need to be done in the winter. So let's take a look at those cold-weather markets. We'll also review some special considerations for conditioning leak seal material and equipment. Then we’ll leave you with a few cold temperature leak seal application tips.

Cold Weather Markets

You have a variety of options for seeking jobs that are inside, and out of the elements, during the winter months.  Hopefully, these ideas will spark more brainstorming on your part. First up we have tunnels, both pedestrian and vehicle. Tunnels often leak, sometimes significantly enough to result in quite a big job. Aquariums are another possibility. As you can imagine, there are infinite potential leak problems in a structure holding that much water. Other possible large jobs could include mines and water treatment plants (which have plenty of interior spaces with potential leak issues). On the smaller side, there are utility vaults, lift stations, manholes, and elevator pits.

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. Wider cracks make leaks more apparent to the property owner and make them easier to repair.

Conditioning Materials and Equipment

One important point to understand is that cold weather requires you to make an extra effort to keep your materials and equipment warm. Cold material reacts slower and gets thicker. Be sure to store your materials and equipment in a heated room the night before the job. When on the job site, there are many ways to keep everything warm. Use an enclosed vehicle, like a box truck, enclosed trailer, or pickup truck with a camper top or bed cover. Keep as much material and equipment inside the vehicle as possible when working. Use a portable heater to maintain a warm temperature. You can also use electric pail heaters to keep your resin ready for action.

Remember that it won’t do you any good to heat the resin if you’re pumping it through cold equipment. The cold steel inside the pump and the cold hose will literally suck the heat out of the resin before it gets where it needs to be. This will increase the viscosity, making it harder to mix with the water and it will slow down the reaction dramatically. So don’t neglect the equipment side of the equation!

Cold Temperature Application Tips

If you’re using a product with an accelerator, you may need to use a faster accelerator or increase your percentage. Also, bring lots of oakum. You may have to use more if the cold temperature slows down the material or the contracted concrete has made the cracks wider.

If your job requires you to inject into a structure underwater (and the water’s cold), you can use a technique called twin streaming. In this approach, you hook two valves together in a parallel fashion – then inject warm water along with the resin to kick-start its reaction before hitting the cold water.

Conclusion

I hope this overview has helped spark some ideas on your part for finding leak seal work during the winter months. Just remember to keep your materials and equipment conditioned and you should be fine. Have more questions about polyurethane leak seal in cold weather? Call us at 404-618-0438.

In this blog post, we will share some tips for stabilizing soil in cold weather. The two main points to remember are – to make sure the ground isn’t frozen and to condition your material and equipment properly.

Do Not Attempt Soil Stabilization Work When the Ground is Frozen

If you’re considering soil stabilization in cold weather, the first step is to make sure that the water table isn’t frozen. Iced earth is not permeable enough for the proper mixing of resin and soil. If you attempt to proceed with frozen soil, you’ll just be wasting your material. Best to wait it out in that case.

Properly Condition Equipment and Materials

For optimal results, it’s best to store any materials and equipment that are to be used in a heated environment overnight. It’s best to keep your AP Soil 600 above 60 degrees at all times. This is key because cold material reacts slower and gets thicker. The methods you use to condition your material on the job site will depend on the type of vehicle you’re using.

If you have an insulated rig, it should stay around 40 degrees warmer than outside temperatures. Most foam rigs have built-in electric heaters that require an extension cord to a power outlet at the job site or at your facility for overnight storage. Alternatively, you could buy an electric radiator heater. Other available heating devices include drum band heaters and heated drum mats (be careful not to scorch the polymers by turning band heaters up too high). For a more DIY approach, you could build a hot box around the material storage area in your rig.

If you’re using pails and a smaller vehicle, use an enclosed vehicle, like a box truck, enclosed trailer, or pickup truck with a camper top or bed cover. Keep as much material and equipment inside the vehicle as possible when working. Use a portable heater to maintain a warm temperature. You can also use electric pail heaters to keep your resin ready for action.

Using a combination of the methods described above, you should be able to keep your materials warm enough. In extreme cases when the material gets a bit too cold and thick, you may want to use AP Cat 600 to speed up the reaction time.

Conclusion

As long as the ground isn’t frozen, you should be able to stabilize soil in cold weather.  Just make sure your materials and equipment are conditioned properly.  If you have any further questions, please contact us at 404-618-0438.

As the weather gets colder, contractors in some regions will need to prepare their slab lifting rigs for storage during the off-season. We're providing step-by-step instructions for that procedure in this article.

Please Note:

• You will notice that more care is given to the A-side of the system, this is normal.
• This procedure assumes you are using a PMC pump.

Prepping a Slab Lifting Rig for Winter Storage

1. Remove and clean the A and B stick pumps. Clean the exterior of the pumps with brake cleaner to remove as much residual resin and polyol as possible.
2. Place the A-Side transfer pump into a 5-gallon pail of the AS Pump Flush.
3. Remove the recirculation hose from the A-Side drum and place it in a purge pail.
4. Open A-Side inlet valve and recirculation valve on your PMC machine.
5. Slowly open the air valve on the A-Side transfer pump to start introducing the AS Pump Flush through the A-Side of the machine.
6. You will notice iso material being pushed out of the recirculation line into the purge pail. Continue to pump AS Pump Flush through the system until it comes out of the recirculation line clear, with no added coloring or debris.
7. Shut the air supply feeding the transfer pump. This will stop all flow of material.
8. Un-cap the A-Side of the PMC whip hose. Once un-capped, place the hose into the purge pail.
9. Close the recirculation valve on the A-Side of the PMC machine.
10. Slowly open the air valve on the A-Side transfer pump to start the flow of AS Pump Flush through the heated hose.
11. You will notice iso material being pushed out of the whip hose into the purge pail. Continue to pump AS Pump Flush through the system until it comes out of the recirculation line clear, with no added coloring or debris.
12. Now that this process is complete, the A-Side has been completely cleaned of any iso material.
13. Remove the A-Side transfer pump from the pail of AS Pump Flush and place it into a 5-gallon pail of AP Lube 190.
14. Slowly open the air valve on the A-Side transfer pump to start introducing the AP Lube 190 through the A-Side of the machine. Continue to pump the AP Lube 190 until you have pure and clean AP Lube 190 coming out of the end of the whip hose
15. Place the B-Side stick pump into a separate 5-gallon pail of AP Lube 190.
16. Slowly open the air valve on the B-Side transfer pump to start introducing the AP Lube 190 through the B-Side of the machine and heated hose. Continue to pump AP Lube 190 through the system until it comes out of the end of the whip hose, with no added coloring or debris.
17. Once the entire system is full of clean AP Lube 190, slowly start to recirculate the AP Lube 190 through the entire system. When doing this, it is best to let the PMC machine cycle while recirculating the AP lube 190.
18. Once all these steps are complete, close the air on each transfer pump and re-cap the heated PMC whip hoses.

A retaining wall at a Georgia-based luxury residence was failing due to the pressure of the surrounding soil. A general contractor excavated the site around the wall and planned to install lightweight foam blocks as a replacement for the heavy soil that was removed. After doing a little more research, the contractor discovered that, due to the cost of shipping the blocks, liquid polyurethane foam installation by a local specialized contractor was a lot less expensive. Liquid polyurethane foam takes the shape of the void before curing to form a high-strength solid mass.

Powerful Polymer

The contactor used AP Fill 420 to fill the void. AP Fill 420 is a two-component, high expansion, hydro-insensitive polyurethane foam. It’s the top slab solution for polyurethane void fill. AP Fill 420 weighs 1.8 to 2.2 pounds per cubic foot.

Painless Procedure

The contractor filled the entire void with AP Fill 420 foam. This material was faster to install, less expensive, and provided a more waterproof solution than the foam blocks.

Rapid Result

The entire void was filled with lightweight and extremely durable polyurethane foam. This material placed minimal pressure on the retaining wall, eliminating the danger of future damage. The property owner was extremely pleased with the results.

New year's message from Alchemy-Spetec Co-Owner and President Stephen C. Barton. (Stephen has been at the forefront of the concrete repair industry for over 30 years. Running leak seal crews in his teens, developing breakthrough polyurethane technology in his twenties, and helping grow the market ever since; Mr. Barton has been a leader in the field for most of his life.)

At the end of every year, I tell my team the same thing. “We have to reinvent ourselves. What got us to this point won’t get us where we want to go.” Every year we do just that. However, 2021 was special. We had to reinvent ourselves just about every month.

I won’t waste your time by repeating the phrase “supply chain issues”. I will say this: our team worked exhaustively to scour the earth for raw materials, reformulate our products, and finally manufacture and test the new formulations. In the end, we did everything in our power to live up to our entire reason for being – to serve our customers.

We learned more in the last year than we have since the inception of the business. We have more raw material options, formulations, and test data than ever before. These lessons learned will help us serve our customers more effectively than ever in 2022.

A lot of people are looking forward to putting 2021 in the rear-view mirror. Personally, I’m going to miss the challenges from last year that forced us to learn and grow. However, I’m sure 2022 will present some of the same issues and some unexpected new ones. I say, “Bring it on!” What doesn’t kill you makes you stronger.

Finally, I would like to say “Thank you” to all our customers who patiently waited for material to show up and endured the sticker shock of rapid inflation. Our team will be there for you again this year. Happy New Year! Now, let’s get to work…
