FLEX SEAL SAVES THE DAY

We got hit with Hurricane Ida in Northeast Queens NY.. We never get hit..This is the first time this section was drowned!!! I truly feel for all those that were hit Katrina....so our basement was completely flooded...I decided to give Flex Seal a try last month...Yes...Last month...waiting for water to dry up and disinfect and clean...plus waiting for the Flex Seal to arrive...Well...Happy to report...very happy with the outcome...it has rained a lot here and thank goodness...not a drop has come through the walls or ground..My husband and dad covered the wall and ground with Flex Seal..last week..we put peel and stick tile...I'M SO GLAD I WATCHED ALL VIDEO'S AND TOLD MY HUSBAND AND DAD THAT WE ARE USING THIS!! MY DAD HAS USED THIS PRODUCT BEFORE.
