“The adhesive is amazing stuff”
I received your system a month or so ago and this past week I took a couple of days to get prepared for installation, drilled holes all around in the base of the blocks to let the water weep out of the foundation walls. Cleaned and prepped the floor and then installed the system! At first I was a bit doubting but once installed the basement is now bone dry and the system is collecting the water and sending it to the sump pump! The adhesive is amazing stuff and even though there were several areas where it was pretty wet (even with sucking the water out with a shop vac before adhering to the floor) the stuff cured and is solid to the floor! This house is going on the market in about 3 weeks and it is nice to know we can show that we have solved the weeping basement issue and made it a nice dry space to use! Thank you and have a great day!
“You have a great product at a great price.”
I actually am in sales for a waterproofing company. I asked my boss what he would charge me for a kit to do my two 30 ft walls that are underground in the basement. He said if I did it myself the materials would be 1000.00 I am proud to report that your materials cost me 336.00 and my installation went off without a hitch and I have a dry basement that drains perfectly out of two gravity drains. You have a great product at a great price.
