Body - Soil Stabilization - Case StudiesThe Polyurethane Soil Stabilization Process

Weak soil under any structure or slab increases the risk of settling and structural damage. Excavating next to a building can weaken the soil that supports the foundation, potentially causing structural damage. Eroding soil can create sinkholes under roads and damage existing infrastructure. In some cases, this erosion is caused by water leaking into pipes and manholes and carrying soil with it. Regardless of the cause, loose soil will result in structural damage over time.

Contractors use Alchemy-Spetec soil stabilization polymers to fill voids and solidify the soil, thus preventing additional structural damage. These polymers are also used to reinforce excavation areas next to existing buildings. The contractor drives pipes in a grid pattern and injects soil stabilization resins to strengthen the soil and protect nearby structures.

Body - Concrete Leveling - Case StudiesThe Concrete Leveling Process

Surface erosion, water damage, shrinking from heavy loads, or void spaces in the soil can all cause commercial, industrial, and residential slabs to sink or, in worst-case scenarios, collapse completely. Even without catastrophic collapse, slightly uneven concrete can cause expensive damage to property, vehicles, and factory equipment - not to mention personal injury.

Polyurethane concrete leveling is often the most cost-efficient and durable solution to this problem. A technician simply drills 3/8-inch holes through the concrete surface. Then, injects one of the Alchemy-Spetec concrete leveling polymers with the MixMaster Pro slab lifting gun. As the foam expands, pressure on the underside causes the concrete to lift to its original level position. The slab is ready for traffic 15 minutes after installation. The repair is waterproof and strong enough to support virtually any structure.

Case Study - Specialty Waterproofing at Hydroelectric Dam

Body - Specialty Waterproofing at Hydroelectric Dam

The John Day Dam is located in the state of Oregon on the Columbia River. In 2020 the Army Corps of Engineers put a repair job out to bid to address a variety of situations, including leaks that were occurring in a number of the galleries (openings or passageways within the dam). The general contractor that won the bid brought Spokane, Washington’s Talisman Construction Services in for the leak seal portion of the job.

Powerful Polymers

The Army Corp of Engineers specified a flexible polyurethane for the specialty waterproofing due to the fact that it would be injected into dynamic joints and cracks (joints and cracks that contract and expand with weather conditions).

The technicians from Talisman Construction Services chose Spetec PUR F400 from Alchemy-Spetec. This product features 100% elongation. If you install a rigid product in a dynamic joint or crack is will fail at the first movement. In addition to its flexible nature, Spetec PUR F400 is also hydrophobic. Hydrophobic polyurethanes have excellent chemical resistance and superior longevity. In addition, Spetec F400 features a field adjustable set time (when you have cold water, with varying volumes, this is essential so you can either penetrate small cracks with a slower set time or shut down gushing leaks with a faster set time).

The Bureau of Reclamation and the Army Corp of Engineers have approved Spetec PUR F400 for use on their structures. This durable repair material has been successfully installed in many of their dams and locks.

Painless Procedures

One of the classic rules of grouting cracks and joints is to pull off the crack or joint half the thickness of the wall and drill at a 45° angle. However, when you get over 3’ thick it is not necessary to pull off the crack or joint more than 1.5’. The crew followed these guidelines when injecting the resin.

On thicker structures leaking cold water at high volumes, it is imperative to be able to adjust the set times in the field. Gen ACC is the accelerator for Spetec PUR F400 and is added at a ratio of 1% all the way up to 10%. The more you add the quicker the product polymerizes. The crew adjusted the set times according to properties of each leak.

They also soaked AP Oakum in Spetec PUR F400, and packed it into the wider cracks and high volume leaks. Depending on the situation, the oakum is sometimes packed in before the injection or packed in simultaneously as a second crew member fills the void with the first crew member is injecting the resin.

Rapid Results

Within a matter of days, the leaks in the galleries were successfully remediated. The general contractor was then able to move on to other parts of their project, on budget and on schedule.

Murray Heywood - Using Leak Seal Grout on Floor Coating Jobs

Posted by Kreg Thornley on Sep 1, 2022 10:00:00 AM

1 1400 х 425

1  800х1200This article is an excerpt from Episode 14 of Alchemy-Spetec's podcast The Injection Connection, featuring veteran coatings expert Murray Heywood. (If you'd rather view or listen, an audio/visual version of this excerpt is posted at the bottom of the article.)

Charlie Lerman: When I’m training people that have never done grouting before, the ones that I find that are the easiest, honestly, are people who do coatings. The reason is that they're already handling paint equipment and chemicals. When you talk to some contractors they say, "Oh, my God, I got to buy an airless paint sprayer? Can't I just use a caulk gun or something?" And when you're starting off at that level, you could use cartridges and a caulk gun, but it's like showing up to do brain surgery and you've got a drill, a hammer, and a kitchen knife. It's not the right way to start off.

We did a webinar with about 50 Sherwin-Williams people. We got a number of good opportunities out of that, but one of the best ones was a flooring guy who just happened to be on there. One of your flooring guys. He got one of his coating guys involved, and he is now a regular grout user. And they don't go chasing the jobs, they just do it all internally when they run into situations. They now say, "This is going to be a problem for our coating. We know it, we're going to go ahead and grout that ourselves beforehand." And that to me is wonderful.

Murray Heywood: One of the biggest problems with flooring - flooring's a nightmare. There are a lot of coating failures on floors and a lot of it has to do with moisture. Because where is that moisture traveling from underneath the slab? It's coming through, it's chasing the heat. It's coming up through, and anything you put over the top without addressing that - it's blistering and causing issues. That's one of the things that was top of mind for me. It wasn't my division, it wasn't my responsibility, but I always thought the flooring people needed to know about this. Because water is a big problem for them.

Case Study - Deep Soil Stabilization at Residential Property

Posted by Kreg Thornley on Aug 18, 2022 10:00:00 AM

Banner - Deep Soil Stabilization at Residential Property

Body---Deep-Soil-Stabilization-at-Residential-PropertyThe residents of a house in Columbia, Missouri noticed the floor in their finished basement was settling. The slab was beginning to sink along the base of a load-bearing wall. It turned out that there was no structural support beneath that area of the floor. They reached out to Absolute Foundation Repair, a local geotechnical contractor. Alchemy-Spetec Geotech Services Technician Jacob Bryant was invited by the contractor to consult on the job as well.

Powerful Polymers

AP Lift 430 is a two-component, high-strength, high-density, hydro-insensitive structural polyurethane foam. This very reliable and consistent material was selected because it is ideal for strengthening and compacting soil. This high-strength closed cell polyurethane bonds with soil and concrete. After installation, the site is often traffic ready in as soon as 15 minutes. AP Lift 430 is also certified to NSF/ANSI/CAN 61 (approved for contact with drinking water).

AP Lift 430 Data

Painless Procedures

The Alchemy-Spetec technical consultant worked closely with the geotech contractor to develop the injection plan. The crew removed the carpet and then drilled holes every three feet along the length of the affected area. Next, they drove injection tubing through each drill hole, four feet deep into the soil beneath the slab. A technician then injected about 20-40 lbs of AP Lift 430 per tube. The crew monitored for lift during this process. The slab was raised about 1/8 - 1/4 of an inch to ensure that the soil was fully compacted. Next, they injected additional material just beneath the slab (a.k.a. shallow injections) to fill any remaining voids. Finally, they removed the tubes and cleaned up the site.

Rapid Results

After only a few hours, the job was completed, and the site was completely cleaned up. The customer was able to conduct her previously scheduled dance class on that same floor later that day.

Murray Heywood - The Importance of Technical Service and Training

Posted by Kreg Thornley on Aug 16, 2022 10:00:00 AM

Banner - Technical Service and Training-1

Body - Technical Service and Training-1This article is an excerpt from Episode 14 of Alchemy-Spetec's podcast The Injection Connection, featuring veteran coatings expert Murray Heywood. (If you'd rather view or listen, an audio/visual version of this excerpt is posted at the bottom of the article.)

Charlie Lerman: I’ve been on the services side for close to 18 years now. So I’m a big proponent of training and providing service. I'd like to acknowledge one of the other manufacturers out there that provides great training. Sherwin-Williams seems like a champion of education. They've got a great technical service group. I wanted to get your opinion on the value of bringing contractors to the trough, to drink, to understand, to learn...things like that.

Murray Heywood: Yeah.

Charlie: I don't even know if that was a question, more of a statement.

Murray: Well, that was one of the things that was unique to our group at Sherwin-Williams. Kevin Morris and I saw Sherwin-Williams as a sales organization. They manufacture paint to sell it. They aren't necessarily a technical organization. But I always believed that the more educated the sales reps are, the more they're going to be able to sell. Because if you don't know as much about something as the person you're trying to sell it to, you're going to have very limited results. But if you can at least talk the talk and walk the walk, and understand what you're talking about, then you're going to be more successful. And you're going to be able to help your customers, which builds a sense of loyalty.

If you solve a problem for somebody, they don't readily forget you. That's how I built my whole career as a rep: help people out, solve problems for them, and they will always come back for more...always. It's very rare that you save somebody some money and get them out of a jam and they say, "Well, I’m going to lose his number." That's not the way it works. So I think that Kevin and I decided early on to always ask ourselves, "How can we make it better? How can we make our people smarter and more equipped to sell?" And it's a whole package because you're selling coatings but we know the number one enemy of coatings is water. They sort of go hand in hand.

So I think that, while running these training sessions for contractors was great and everything, I saw that educating our own people is almost more important. That way our people can go out and help these guys. The training sessions we did were very successful. This has been a pet peeve of mine with every sales organization I’ve worked with in the paint world - you can't just find another one. It's not like selling shoes or widgets. There's a technical aspect to coating sales, especially on the industrial side. And the more you educate your salespeople, the better they're going to be. You're also reducing your own risk at the same time by doing things right.

We just talked about the cause of failure being ignorance and indifference. Indifference to quality, ignorance of quality. My old man, for example, thought he did good work. He just thought everybody else was too fussy. His attitude was, "Oh, it'll be fine." And I was a young guy who was saying, "No, I don't think that's right, Dad. I think that's a horrible plan." My dad never used his blinkers while driving and it used to infuriate me. I’d say, "Dad, you've got to use your blinkers, man." He'd reply, "Listen to me, smart guy, I’ve been driving for years and I’ve never had an accident." And I would think, "Yeah, well, you've left a trail of destruction behind you. You just don't know what you don't know."

And that's kind of like contractors who think they're doing well, but they don't realize that what they're missing is creating a whole backlog of problems. So all this training needs to happen with coating manufacturers. I mean, what could you possibly lose by being smarter about your products? Why not? As  sales organizations, and I can speak candidly about this now because I don't work for them anymore, we spent so much time on sending people to this or that random training or some feel-good training. All that kind of stuff that doesn't move the needle at all. It's just so somebody can check off a box and say, "Yep, we accomplished that."

It was always more difficult when we tried to push them through real technical training because you don't do it in one afternoon. We used to run our boot camps if you remember, and they were intense weeks of training. We were getting things in people's hands, getting a grout gun in their hands, and hooking that nozzle up to the zerk and pumping it. That kind of stuff. Hands-on. That's how I learn. I learn by doing, and so I think the more that you can convince these coating manufacturers to accept this kind of training and to invest in it, the better. Because if you think about it, we know that we haven't even scratched the surface of the biggest opportunities in waterproofing and grouting. We're usually dealing with the obvious things. But there's the stuff that's not obvious that it also can fix - and that is the biggest opportunity.
