RILEM Repellency Testing is a method used to assess the water-repellent performance of concrete by measuring the rate of water absorption using a standardized tube device. Repellency testing of treated and untreated concrete samples clearly shows that concrete with Impede® IntraSeal in the mix protects against water absorption over time.

Today, Impede® IntraSeal is trusted to protect over fifty million square feet of concrete.

Along the way we have encountered a number of imitation products. Don’t be fooled. Head-to-head performance testing indicates that nothing measures up to
Impede® IntraSeal.
