Mar-flex Waterproofing & Building Products

10 out of the 10

As a foundation waterproofer, I've been working with this company since 2005. Great products and team! Highly recommend!

I had some troubles with the basement crack repair kit but while writing my review the foam expanded filling in all the cracks and I expect it will do the job. So, happy but with a couple of constructive comments. First, hold the tip on with one hand while you squeeze the plunger as it doesn't stay on. Second, note the plunger is empty when it is only half way down the tube. Third, make sure to put plenty of the covering material at the bottom of your crack so all the goop doesn't flow out the bottom. If you seal the bottom of the crack first, replace the tube when it gets hard even if it seems you should have more to go, and hold on to the tip while you squeeze, you'll be fine. Great idea, great kit, good price, but they really should fix that tip.

Outstanding service!!!
