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.

Murray Heywood - Creating a Site-Specific Grout Application Plan

Posted by Kreg Thornley on Aug 9, 2022 10:00:00 AM

Banner - Creating a Site-Specific Grout Application Plan

Body - Creating a Site-Specific Grout Application PlanThis 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: One of the things I say and again - and I’ll bounce this off you since you're from the coating side - I always contrast our grouts to coatings because with coatings, you can see them, you can touch them, you can do all kinds of tests. And I also always say it behooves us to train our contractors well and support them to get the products installed correctly because it's not like a coating. When you're a coating manufacturer, if there's a problem with your coating, you come out there, you do a pull test, you do a spark test, you can check the millage of it, you can say the surface prep was wrong and you could say, "You know what, you didn't follow the right installation procedures." With grouting, I’d come out and say the same thing that the contractor didn't follow the correct procedures, but what are we going to do? Cut the wall out? Dig up the whole thing in downtown and show? We can't prove any of that. It's very important. Grouting gets a black eye when it's not installed right because we can't test all those things. And I think that's one of the reasons that grouting has always stayed kind of small is because there are no really great, quantifiable, repeatable engineering tests that work everywhere to test grouting.

Murray Heywood: No, it really comes down to, did the water stop, right?

Charlie: Yes.

Murray: And if the water doesn't stop, that doesn't necessarily mean that there was something wrong with the grout. It's often that the problem was bigger than you thought because you can't see it. You're doing educated guesses. As a grout geek you know, "Well, I’ve seen this before. I know that we're going to have to put a port here and we're going to chase it around here." You can make some educated guesses but you're right. I can go in with the coating and with my gauges and test the DFT and quickly say, "Well, your spec said you're supposed to have 40 mils on here. You've got 20. So you're half of what you should be. Shame on you." Or I can pull the coating off and say, "Well, you have no surface profile, you didn't prepare it." And I’m sure the skeptics are thinking, "Oh, yeah, well, you're just saying that to cover your own butt." It’s virtually unprovable other than, when the water didn't stop it's obviously not working. And they say, "Well, your grout’s no good." I do a lot of failure analysis and failure investigations. That's the majority of what I do now is failure analysis. And I like that, it's kind of like CSI Paint. And I enjoy that. But still to this day, 100 years into this coating thing, the biggest cause of failure is poor application, poor surface preparation, and poor environmental conditions during the application. It always relates, 98% of the time, back to something that didn't go right with the application. And that can be the same with grouting. If you don't know how the water's flowing or if you can't make some educated guesses on how the water's getting in, you don't know where to start. And sometimes, as you know, you could be pumping grout in one side and it's coming out the other side and not doing anything.

Charlie: It always goes somewhere. It's about how we get it to go where we want it to through a foot of concrete. How do we control a liquid? That's what it comes down to.
