As the Director of Technical Services for the Leak Seal division at Alchemy-Spetec, I often find myself assisting customers with some interesting jobs. Such was the case when I was called in to consult with a contractor who was sealing a leak in a historic district below-grade, multi-course brick wall. As is often the case with below grade, historic spaces, water infiltration was unsightly, gave off a musty odor, and was damaging to finishes. This was a very old brick wall, approximately 8 x 15 feet in size and at least three courses thick. The owner wanted to find a way to waterproof this vintage brick structure while at the same time preserving its unique appearance. In addition to the water flow issue, the leaks were causing mold/mildew on the walls.

We proposed injecting Spetec PUR AG200, a high-strength elastic acrylic injection resin, into the cementitious grout between the bricks where the water was migrating through. In order to monitor the efficacy of this leak seal job, we employed the QP Factor® leak seal testing and quality control system. As stated on our website, “The QP Factor® system offers quantifiable water flow, pressure, and flow/pressure metrics before and after leak seal injection that will provide clients, contractors, and design professionals the industry’s first patented method for proving Leak Seal® success.

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 AG200, 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.”

We ran the QP Factor® system on three test areas in the wall before beginning the injection process. This revealed to us the amount of water that was flowing through the wall. After injecting Spetec PUR AG200 into the existing cementitious grout around the bricks in two of those test areas, we ran the QP Factor® tests again and realized that wouldn’t have to inject the third area due to the efficacy of the Spetec PUR AG200.

In addition to stopping the water flow, sealing the leaks made it possible for the bar owner to keep the walls clean in appearance. See the treated area of the brick wall vs a non-treated area.

Why Use Polyurethane for Seawall Repair?

Non-Intrusive Application
Polyurethane can be injected through pipes directly into voids and loose sandy soil using small portable equipment.

Proven Solution
Seawall repair resins are used extensively seal cracks, voids and defects as well as for filling voids and stabilizing the soil.

Creates an Impermeable Mass
Polyurethane seals leaks along the wall, fills the voids that have occurred, and mixes with the soil to form a solid, impermeable mass.

What Are the Results of Polyurethane Seawall Repair?

Long Lasting Solution
Alchemy-Spetec seawall repair resins cure to a strength greater than crystalline bedrock. Combined with proper drainage, this method can greatly extend the life of your seawall.

Water Tight Seawall
The resin reacts with water or moisture in the soil and expands to fill voids while it permeates sandy soil to form a solid, strong, watertight mass.

According to the Detroit Free Press, rising water levels on the Great Lakes have hit records in 2020, leading to extensive flooding and unusually aggressive shoreline erosion. Many property owners and contractors in the area are now researching seawall repair methods. This type of research typically reveals three options: the common methods of excavation or repair with cement grout, and the next generation method of repair with high-strength polyurethane.

Common Seawall Repair Options

In a previous blog post, An In-Depth Look at Polyurethane Seawall Repair, Andy Powell explained two of the most common options, along with their drawbacks...

Seawall Excavation

You can tear out the wall (or part of the wall) and replace it. This approach has a few daunting downsides. Namely, it can be…

• Costly
• Time consuming
• Environmentally damaging
• Requires time consuming permits

Paying for a new seawall is no doubt going to cost more than any kind of repair. A complete rebuild will also take some time. Not to mention the inevitable mess, a good portion of which is likely to end up in the water. Excavation also requires getting a permit, which can eat up a LOT of time. 

Seawall Repair with Cement Grout

We still see contractors and property owners filling sinkholes and trying to plug seawall leaks concrete. This outdated approach has many disadvantages when compared to polyurethane repair. For example, it’s…

• Product, labor and machinery intensive
• Time consuming
• Prone to degradation
• Heavy (adds weight to seawall or bulkhead already under stress)

The amount of cement grout, labor and machinery required can be quite disruptive as well.  Compared to the stealth, surgical approach of polyurethane repair, the property owner can end up with quite a mess on their property during a cement grout repair job. Needless to say, with all this extra material, machinery and labor – the whole process takes longer than your typical polyurethane repair. Cement grout is known to shrink and degrade over time as well. Imagine the frustration of paying for an expensive seawall repair, only to see it wash out over the next few weeks. Cement that doesn’t wash out can add weight to the structure and sink over time.

Next Generation Seawall Repair with Polyurethane

Polyurethane repair material addresses the primary weaknesses inherent in excavation and repair with cement grout. This includes minimal disruption from equipment, labor, and messy materials; plus a quick return-to-use time. Alchemy-Spetec offers high-strenth polyurethane foams for repairing seawall cracks, voids, and surrouding soil.  Alchemy-Spetec seawall repair foams are also NSF-approved for contact with potable water.

One request we often receive is to explain the difference between AP Fill 700 polyurethane foam and cement grout for soil stabilization. When you're asked a question repeatedly, it's probably a sign that the answer(s) would make a good blog post. So here they are...

AP Fill 700 is a one-component, water activated, hydrophobic, low viscosity, closed cell foam. It adds no weight to the soil, has a quicker set time, resists erosion, and displaces groundwater, and expands during installation - penetrating small soil gaps in the process. AP Fill 700 can also be adjusted to work in flowing water and installed in any climate. These are all very beneficial characteristics for soil stabilization. As you'll see in the comparison table below, the characteristics of cement grout are not exactly the same.

Comparing AP Fill 700 & Cement Grout for Soil Stabilization

Environmentally Safe

AP Fill 700 is NSF approved for contact with potable water, ensuring compliance with the Safe Water Drinking Act (SDWA) and guaranteeing peace of mind for in-the-field stakeholders on soil stabilization projects.

This article is an excerpt from Episode 8 of Alchemy-Spetec's podcast The Injection Connection, featuring Matt Chittick and Travis Germick, co-owners of Lift It Rite, LLC, a residential slab-lifting business. The 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 watch the video clip of this exchange, it is posted at the bottom of the article.)

Jim Spiegel: When you’re on slab lifting job, what do you think holds you up the most often?

Matt Chittick: I would say binding slabs are the hardest thing that we deal with. But we've done a couple of jobs here recently where the bind was good and it allowed something to come up together like we needed it to, versus breaking that crack that was binding apart and lifting one side versus the other side. But binding slabs are generally the hardest thing to figure out and make work for you, I would say.

Jim: So, when you have something binding, when do you make the decision to cut into it?

Travis Germick: Well, you can look at it and say, okay, there's a possibility of it binding or something like that, we'll go ahead and take care of it. I mean, those saw blades we were talking about earlier in the podcast are amazing that we picked up. So we’re not as scared to pull it out and saw through what we got to saw through.

Matt: They cut like butter. That was an actual company that we met out there at the World of Concrete. We bought three blades from the guy. Well, actually he sent us one first. We tried it, we were like, yeah, need more of these. And I don't think we've used any of the ones we just bought. I think we're still on the first one.

Travis: We are. I mean, they're really good blades.

Jim: You want to give them a plug? What kind of blade is it?

Matt: Diamond Blade Warehouse.

Travis: There you go.

Jim: Super blade from a Diamond Blade Warehouse and of all the blades you've used, you think that's one of the better ones?

Travis: Yeah it really is, whether it's a cured concrete, old stuff where the house has been there for forty years or whether it's stuff that’s two years old.
