Leaking concrete structures can be permanently repaired with concrete crack injection by using a water activated flexible foam. Pressure injection of these liquid polyurethane resins forces the material into leaking cracks, joints, and other defects. After the polyurethane crack injection is complete, the polyurethane resin rapidly reacts with water to form a flexible, watertight seal.

Curtain wall grouting is a leak seal method that is often required when cracks cannot be identified, when 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 widespread 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.

We had a great response to this blog post when it was first published last year.  All the sentiments still apply and all the key points are still critical, so we're sharing it once again...

It’s the Friday before Christmas and the marketing department is trying to get one more blog out of me before the holidays.  They wanted a Christmas themed blog that is somehow industry related so I’ll do the best I can.

This time of year most people will spend a little extra time with their loved ones.  It is also a time to reflect on the loved ones we miss that are no longer with us.  In the past year, some people I know in our industry have either been lost or have suffered through a loss.  In those cases there was nothing that could have been done to stop it.  However, there are things that we can do to guard against job related safety hazards.

I recently had the opportunity to spend a day in an OSHA safety training class.  It was required in order to be present supervising a project at a chemical facility.  Signing in at 6 AM, I’ll admit I was not looking forward to spending all day there.  By the end of the day I was glad that I went.

In an intro video, the narrator said that every morning when you kiss your loved one goodbye before you go to work, keep in mind that someone, somewhere will not come home from work that day.  Workplace accidents are almost entirely preventable.  Investigations typically find the cause quite easily. 

The class I attended contained a dozen or so modules, each one with a video case study followed by the teaching.  Every case study module covered a different accident where people didn’t come home from work that day.  All of them could have been prevented.  I learned about fire, electrical and chemical safety; as well as confined space, ladders, scaffolds, and working in trenches.  I have worked in the construction industry since my teenage years, so it was sobering to look back and think about some of the close calls I had.

If you're a contractor or industry related business owner looking for a good $100 investment, send your employees to one of these classes.  It’s a good opportunity to learn safety principles that can protect you, your coworkers, and your business from being lost.  It’s a gift that will keep on giving.  You don’t need Christmas as a reason to do this, but in the spirit of the season, you may want to make it the reason.

Merry Christmas and Happy New Year.

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.

Cold Weather Markets

Seasonal attractions such as theme parks 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.

Factories can be less active in the winter months with production slowing down in many industries. This is a good time for them to do maintenance and floor repairs as well.

Warehouses typically operate year round, so there is always work available. Warehouse floors are used and abused on a daily basis and will sooner or later need some form of repairs done to keep business running at a steady pace. In addition, many warehouses have dangerous voids beneath their floors that require repair.  

Exterior concrete slabs are still worth considering, even in the cold weather. These slabs experience the most wear and tear from the environment itself (think erosion) and daily traffic. You’ll need to lift concrete slabs before the ground freezes and only after your materials have been thoroughly conditioned.

Conditioning Materials

Your slab lifting equipment probably has built in heaters and a heated hose. Each brand and model of pump has different sized pre-heaters and different ∆T (∆ = Delta and T = Temperature). This sounds complicated, but is actually quite simple.  ∆T is simply the change in temperature.  Let’s say your material has been sitting in a cold trailer all night and the temperature has dropped to 40 degrees F. If the required temperature of your B side material is 120 degrees F, then your pump better be rated with a ∆T of at least 80 degrees. However, if your material is preconditioned to 70 degrees F, then your machine only has to be rated for a ∆T of 50 degrees. As I said, every machine is rated differently based on the size of the heaters. What is important to know is that there are limitations to how much heating your machine can do.

Keeping your materials conditioned in the winter months is a lot easier than it sounds. The main point is to keep your AP Lift products above 60 degrees at all times. Keeping the polyurethane at or above that temperature can be accomplished in a number of ways.

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. Alternately, 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.

Heat Sink

Another consideration when lifting cold slabs is the heat sink factor. AP Lift products come out of the gun hot and get even hotter as they react. However, cold concrete acts as a heat sink and sucks the energy out of the foam as it starts to react. This can slow down the reaction speed of the foam. If you are pumping into a void, it will have little effect because most of the foam is not in contact with the concrete. If you are trying to lift a slab with little void, it will have more of an effect because more of the foam is in contact with the cold concrete and cold soil. More volume = more energy.

Conclusion

Don’t let common preconceptions deter you from slab lifting in cold weather. As noted above, there is no need to shut down completely for the upcoming winter months if you don’t want to. Opportunities still exist and one of them may just be the job you’ve been looking for all year. There are many ways to keep your equipment and materials conditioned to efficiently work in lower temperatures. Have more questions about slab lifting in cold weather? Call us at 404-618-0438.

This video demonstrates how concrete crack injection works for leak seal problems. Leaking concrete structures can be permanently repaired using a water activated flexible polymer. Pressure injection of these liquid resins forces the material into leaking cracks, joints, and other defects. The resin rapidly reacts with the moisture to form a flexible, watertight seal. From hairline cracks to gushing leaks, virtually any defect can be corrected with our leak seal resins, optimized for stopping water flow.   

In this case the concrete wall in the basement of an apartment complex was leaking water, slowly flooding the area at the base of the structure. Needless to say, these types of situations can eventually present a fairly serious issue for property owners. Fortunately, they can attack the problem head on by hiring a contractor skilled in the application of Spetec PUR GT500 (formerly known as AP Seal 500).

Spetec PUR GT500 is a single component, low viscosity, flexible hydrophilic polyurethane injection resin. This grout is a proven industrial concrete crack sealant. A powerful polyurethane resin that is optimal for sealing hairline cracks, pipe penetrations, joints and larger defects in concrete structures.

Are you familiar with our Waterstop line of preventative waterproofing products? Make sure to ask us all about them when you visit our booth at  World of Concrete 2019! Drop by to see us at Booth # O40551 in the Silver Lots (same location we were in last year).

A Brief Overview of the Waterstop Line

Newly constructed floor/wall joints with no waterstop lining can be vulnerable to water infiltration. Neglect to line the joints, and water will 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.

Spetec ITS Kit
The Spetec ITS Kit is a complete injection tubing system for sealing of construction joints in concrete. It can also be used to seal cold joints, expansion joints, pipe penetrations, and tunnel segment joints. In addition, this kit can be used as a primary waterstop system.

Spetec R-ITS
The Spetec Re-Inectable Tube System is a primary waterstop in cold joints and pipe joints. When used with acrylates like Spetec AG 200, it can be flushed with water at a pre-determined set time, creating a clean tube ready for subsequent use. It can also function as a standard single-use injection tube system with polyurethane injection resins like Spetec PUR H100 and Spetec PUR F400. The Spetec R-ITS is compatible with combination grouting techniques involving microfine cements.

Spetec SST500
This is a black hydrophilic synthetic waterproofing strip. Spetec SST500 swells up to 500% of its original size upon contact with water and is used to seal pipe penetrations as well as wall/floor joints. This is a caulk designed to swell and/or expand in the presence of water. It is safe for marine environments and can be applied under water. Spetec WT400 is used to seal pipe penetrations, wall joints, and sheet pile joints.
