The Gripset Betta Waterproofing System ensures the most critical areas are protected so the waterproofing application is successful, surviving the test of time.| Waterproofing Corners take away the guesswork at the most volatile areas, ensuring a quality watertight seal that accommodates movement in a variety of different waterproofing applications.| These corners are made from a unique grade of rubber, providing an elastic “flexible zone” that follows the line of the wall/floor junction, forming a rupture resistant seal at corner intersections.
