Crystalline concrete waterproofing materials like Xypex and Penetron are typically a liquid that is either brushed or sprayed on. These type of materials form crystals within the pores and capillaries within the concrete in order to make the concrete more impervious to water/moisture. They use cementitious materials which are hard, brittle and offer no elongation/flexibility what so ever to seal joints & cracks. When/if even minor movement occurs, these cementitious materials rely on crystals to react with the presence of leaking water to work.
The SANI-TRED crystalline waterproofing coating system products permanently adheres by the first coat’s penetration into the concrete then curing to become as tough as a tire inside the concrete. All joints, seams, cracks and holes are then patched/sealed using LRB/TAV mixture which molecularly welds to the underlying PermaFlex liquid rubber coating. Then a topcoat of PermaFlex is applied which molecularly welds to all of the underlying. This creates a permanently bonded, flexible, monolithic and waterproof seal throughout. Sani-Tred products do not only waterproof concrete.
Sani-Tred products are the only materials that have been proven both ‘in the field’ and laboratory proven to seal out over 99% of radon. Sani-Tred product have 590% elongation/flexibility and molecularly weld to ea ch other so there are no weak links from one application to another.
