We’re starting to see progress now, which is exciting! The focus this week was making sure that we’re set for the below grade systems so that blockwork can begin next week. As we explored sustainable options for below-grade waterproofing for our elevator shaft and basement, we quickly discovered that many of the products available on the market are neither environmentally-friendly nor particularly healthy for installers. Fortunately, Scott Martin, a regional representative for Tremco was able to talk us through our options and point us to Tremco Paraseal Bentonite Waterproofing system.
The bentonite system is a natural alternative to petroleum-based waterproofing products, so it's better aligned with our sustainability philosophies. Here's how it works: The clay is affixed to a 15 milimeter high density polyethelene (HDPE) backing and installed so that the clay is pressed against the concrete walls. Then a drainage mat called TremDrain is installed to the outside of the waterproofing, which enables moisture to drain down and away. The HDPE is the first line of defense against moisture intrusion into the basement. Any moisture that gets past this point will saturate the clay, which will swell as it absorbs water, closing up the gaps and creating a seal to prevent moisture from infiltrating into the elevator shaft and the basement. How clever is that?!
The bentonite product comes in large (heavy!) rolls and it’s attached to the concrete walls with shot pins. Once the Paraseal and the TremDrain 1000 are installed, we’ll install EPS insulation in place behind it. Then we’ll backfill against the walls to hold the system in place.
Were able to source the Paraseal from Sealant Specialists, a local company literally just down the road from us. We imagined it would be a challenge to find a contractor qualified to install the Paraseal system.
Fortunately, everyone we talked to as we were sourcing Paraseal had the same recommendation: work with Dan Martin at Advanced Surface Innovations. And no wonder! Dan has been using the Paraseal system since _________ and his team is familiar with how to install it properly.
Dan founded Advanced Surface Innovations in ________ because _______. He now has a team of __________. Their speciality is __________.
We were on a time crunch to get our waterproofing done so that we could begin backfilling and move on to the next phase. Fortunately, Dan managed to squeeze our project in between a couple others. His installers were quick and professional and they worked with our field crew to get the bentonite waterproofing system done in just a couple days. It looks like we may have a couple other projects for Advanced Surface Innovations to do in the coming months as we finish up the next phases of the project. We’ll be glad to have them back!
