our shed is on a concrete foundation and when it rains ..... it leaks and is on the shed floor. we've tried a few things to fix it - other then lifting the shed and resealing. I bought this to try...... to my surprise - it worked!! No more leaks! Now hubby can finish his shop.

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.
