Waterproofing in Confined Space

Below Grade Waterproofing
GSM Roofing has been defending buildings from water for more than 60 years, so it only made sense for us to make the logical transition into the world of waterproofing. We’ve learned that water doesn’t always flow down hill, it will expose poor workmanship over time and it wreaks havoc to membranes and blocks in a freeze/thaw cycle. Our technicians understand the intricacies of hot fluid applied, single ply, bentonite or self-adhered waterproofing. So, whether it’s below grade or above, a plaza deck or a patio, a foundation or an access tunnel, new construction or a retrofit, we’ll fortify your building from the greatest of all enemies … water.
