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 This outdated approach has many disadvantages when compared to polyurethane repair.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.

(If you'd rather watch the video clip of this exchange, it is posted at the bottom of the article.)

Jim Spiegel: If there's one thing that you guys, a piece of advice or some sage wisdom, as I know you guys are full of that as well as punch lines (laughter), what would you say to someone thinking about getting into the lifting business?

Travis Germick: If you're going to get into the industry, I would say get with Alchemy-Spetec and get some training. Hang out with those guys, come down and watch someone do the work. Get with a reputable company, come with us and work for a day or two and see what it's all about.

There's a lot of people that can definitely do this job but there's also a lot of people that could not do this job. There's a work ethic that goes with it. And I think with any spray foam or something like that, if it's insulation or whatever it is but there's a special ethic that has to go with it and special type of person it takes to get into this. But we absolutely love it. Every day, we get up, we're excited to do what we do because our customers’ minds are blown every time they see foam lifting concrete. And we feed off of that. I mean, they're over there like, “wow, that was cool” and I'm like, “I know, right?” That was really neat. We’re really psyched about it as well. There's a lot of times where Matt and I are high fiving each other because, that was a really cool job we just did.

That’s the only takeaway I have with it. I think it's a great industry to be in. I think it's a great service that we're offering and it's cool, too. It really is some neat stuff. What do you think, Matt?

Matt Chittick: I 100% agree. I would tell somebody you can learn all the ins and outs of it but until you get on the job sites and you see some things happen and you kind of roll with the punches, me and Travis, we have fun. If you have fun, it doesn't feel like you're working. And I would say have fun. You want to look for more good jobs than bad, but don't let the bad jobs bring down your attitude because your customers will feed off of your attitude. If you have a great positive attitude, those customers are going to have a great positive attitude. And if they have a great positive attitude, guess what, they love writing checks.

Jim: Yeah. I couldn't agree with you more that the attitude is such a big part of it. And then that starts when you get out of your truck, right?

Travis: Absolutely.

Jim: If you get out of your truck and you’re all smiles and having a good time with them, it just leads into a good experience. Not only do they feel like they trust you, but when things go wrong, they're more tolerant, I feel.

Matt: Yeah, absolutely. I would say because of our attitudes and things like that, we've been able to explain some things to customers and show them what happened here, what happened there and whatnot and they know that we're professional because that's the way we come across. We keep them involved in it, and when they see these things happen, I think they are a lot more tolerant and really accept some of the imperfections. That might be because getting concrete back to the original exact part or area whre it was might not always be what you can do. But if you talk about those expectations and you keep the customer informed and you're upbeat and positive, that's just going to transcend right to your customer and then everybody's okay and everybody's having a good day.

This post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers.  This article, written by Robin Smith of Dalinghaus Construction, reviews common causes of trip hazards and the repair solution of polyurethane concrete leveling.  If you're an Alchemy-Spetec customer and you'd like to discuss writing content for our blog, please send an email to marketing@alchemy-spetec today!

Raise your hand if you have ever tripped walking down the sidewalk!

Well you are trippin’ for 1 of 2 reasons:

1. You are uncoordinated, and can’t be trusted to walk and chew gum at the same time (that would be me).
   OR
2. Uneven concrete slabs created a trip hazard that you have just fallen victim to!

What causes concrete to shift, become uneven, and cause these trip hazards?

• Expansive clay soil: Expansive clay soil is prone to swelling and shrinking. Changes such as temperature, drought, and moisture causes it to expand and contract...causing the concrete to move.
• Soil compaction: When preparing to build a home, the soil must be moved around, or graded, to create a level base to build upon. If the soils aren’t properly compacted before the concrete is poured, over time, it eventually compresses and can settle. This settlement can cause the concrete to shift.
• Leaking water: If a plumbing or irrigation line springs a leak, it can erode the soil around the concrete, causing it to be unstable.
• Poor drainage: Similar to a leak, improper drainage can also cause erosion.

Concrete removal and replacement can be costly. There is a cost effective solution that can even out those dangerous trip hazards in just 1 day!

Polyurethane concrete leveling to the rescue! Polyurethane concrete leveling, also known as “polyjacking”, is a process in which the contractor drills small holes through the affected sunken slabs. A port is then placed in the hole, the polyurethane is injected as a liquid, then quickly expands to lift the slab back into place.

If you are a visual person like me, check out this video on the Dalinghaus Consruction YouTube channel...

Whether it is a sidewalk, porch, patio, or a VERY busy Orange County Transportation Authority bus stop (insert one more rad video)...

...polyurethane concrete leveling is often an excellent solution, without breaking the bank!

This post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers.  This article, written by J.R. Crowell of Helms Polyfoam, explains why polyurethane slab lifting requires less downtime than alternative repair solutions (and why that's an advantage for property owners & managers).  If you're an Alchemy-Spetec customer and you'd like to discuss writing content for our blog, please send an email to marketing@alchemy-spetec today!

When deciding on a repair plan for a commercial facility, no matter the type of repair, one very important factor to consider is downtime. That old expression “time is money” is not a joke, especially when we are talking about downtime for a business.

A large portion of repairs in the commercial market, whether it be concrete lifting, soil stabilization, or void fill, are in areas with high traffic. This traffic usually consists of forklifts, heavy equipment, and semi-truck and trailers, all of which have a dollar amount tied to their load or run time. Every minute they are aren’t running is a minute they 1) are not making money or 2) are losing money on a late delivery or late project completion.

How is Polyurethane Foam Beneficial to Downtime?

Small Footprint:

Polyurethane repairs generally require only one truck or trailer or even smaller equipment. Crews can work around high traffic areas and times to ensure that daily workflow is minimally impacted.

No Excavation:

Repairs are completed using polyurethane resins injected through a 3/8” – 5/8” hole. These injections are completed from the equipment mentioned above, requiring no heavy equipment. No heavy equipment means that employees will not have to alter their site flow to navigate around a large excavator or concrete truck.

Fast Cure Time:

When it comes to concrete lifting, polyurethane resins begin to set up within 15 seconds after injection and are 90% cured within 30 minutes. This means that by the time the crew leaves the site, the treated areas are ready for “business as usual” and can allow normal traffic. Compare this to demolition and concrete pouring (days of labor and curing), and you see a huge savings on downtime.

If time truly equals money, and we all know it does, the above three reasons show how a polyurethane repair can keep downtime to a minimum and maintain an efficient workflow, thus keeping the bottom line in order. When comparing estimates of various repair methods, don’t get stuck on the dollar figure, always compare the total repair plan and what it could cost on the back end.

Storms, tidal action, and soil erosion constantly cause damage to seawalls. It is essential to identify any problems as early as possible. Here are the most common warning signs of seawall failure:

Blocked Weep Holes

Weep holes function as a pressure-relief valve that allow for drainage of any water that gets behind a seawall. They are visible from the water side, just above the surface usually. A clogged or blocked weep hole could spell trouble. If you find debris in the weep holes, act immediately to prevent water pressure from building up and damaging the seawall.

Voids and/or Sinkholes Near the Inside Edge

In many cases, too much water leaks through to the inside of the seawall. Voids and sinkholes then appear on the land side of the wall due to a loss of soil underneath. Removing the grass near the edges of the seawall to expose possible holes is good practice.

Expanding Concrete Cracks

Damage to concrete in a seawall can expose the interior steel rebar to water. Over time, the rebar (which structurally supports the concrete) can begin to rust and stain the surrounding areas. The added rust causes the rebar to expand, and cracks in the concrete begin to grow.

Polyurethane Seawall Repair

Many seawall issues can be resolved or even prevented with polyurethane seawall repair. Polyurethane can be injected through pipes directly into voids and loose sandy soil using small portable equipment. Polyurethane seals leaks along the wall, fills the voids that have occurred, and mixes with the soil to form a solid, impermeable mass.
