Advantages of an injection test field with Stephan Delarue
You know what I hear engineers and technicians say all the time? “The only thing I ever use for watertight is foaming polyurethane” And you know why they say that? It stops leaks fast, so everybody loves it. Trouble is, foaming polyurethane sucks up water like a sponge. And when it gets saturated, you’re back…
Maybe you’ve asked yourself the question, what does it take to get into a bigger part of the concrete injection game—namely lifting concrete slabs, polyurethane underpinning, or other major geotech jobs. Many of you may run businesses or have experience working with waterproofing, joint filling, and membrane work. But bigger geotechnical projects are, as my guest Jim…
One complaint I often hear from clients who have ordered concrete leak sealing procedures in which an acrylic gel was used is that under some conditions, the expansion joint leaks again. This problem happens typically because of dry weather, which causes acrylic gels dry out and shrink. And when acrylic gels dry, they lose their elasticity,…
In today’s episode of Concrete Injection Made Easy, I discuss sealing expansion joints with my guest Dennis Wagner, Product Manager of Injection Products at Normet. We explore a common problem on the job site, which is typically caused by mistakes with installing water stops, namely leaking expansion joints.
The 12th episode of Concrete Injection Made Easy is a transcript of yesterday’s webinar, which was a session of answering your questions. I replied about why I insist on drilling smaller holes and using smaller than 13mm packers. Why drill such large holes? It’s a waste of time, resin and concrete deterioration. Let’s not do…
You know, I hear people wonder if the watertighting business is here to stay. Pros who’ve been in the game for a long time, say it definitely is. And that’s because projects are getting bolder in design, and construction is taking place in ever more challenging terrain. In today’s episode of Concrete Injection Made Easy, I…
