SANI-TRED® Systems

SANI-TRED® was started over 20 years ago with the goal to create the World’s First Permanent Waterproofing solution. We have developed the only indoor PermaFlex waterproofing system that completely seals basements and more permanently, no matter how wet or deteriorated. SANI-TRED® permanently increases the value of any home with its lifetime warranty. We have served thousands of customers over the years with both big jobs and home fix up jobs.

SANI-TRED® is the world's most unique, versatile, and problem solving line of liquid rubber coating systems! Compare our products’ tensile strength with other products in the world. On average Sani-Tred® PermaFlexproducts are over 4 times stronger than other "seemingly similar" waterproofing products coupled with many more unique qualities and abilities others don’t have which make SANI-TRED® products superior to our competitors.

These unique qualities enable SANI-TRED®PermaFlexproducts to be a permanent solution for many types of applications such as: Basement Waterproofing System, Problem Radon Elimination, Fiberglass and Concrete Swimming Pool Repair, Basement Flooring, Flat and Metal Roof Coating, Pond and Fountain Coating and many more applications.


The Technology Behind Sani-Tred PermaFlex™

Due to unique technical breakthroughs in polymer chemistry, a complete, permanent indoor or outdoor waterproofing and repair system is now available to do-it-yourselfers, and contractors. SANI-TRED® offers PermaFlex™ waterproofing technology that isn’t available in any other product.

Flexible Penetration®

PermaFlex™ penetrates deeply into the pores of the building materials, then cures as tough as a truck tire, making it is impossible for SANI-TRED® products to bubble, peel or delaminate.

Permanent Elongation Technology®

SANI-TRED® products never become harder or brittle with age, they maintain their flexibility indefinitely. SANI-TRED® products have over 590% elongation!

Elongation Memory Technology®

This physical quality ensures that when SANI-TRED® waterproof products are compressed and relaxed, drastically stretched and released, that they always return to their original shape and size.

PermaFlex Waterproofing Coating

SANI-TRED® PermaFlex™, is a liquid polyurethane coating that penetrates deeply into and will bond permanently to properly prepared concrete, wood, aluminum, steel, and some plastics, as well as most all other standard building materials. PermaFlex™ will never bubble, chip, peel, crack, or delaminate from vehicle traffic, exposure to extremes of ambient heat up to 250°F, or Negative Hydrostatic Pressure. PermaFlex™ is environmentally safe, safe, solvent free, non-flammable, and low VOC. PermaFlex™ is extremely durable with 2,030 psi tensile strength. PermaFlex can be brushed, rolled or even sprayed on.


Liquid Rubber Base

LRB (Liquid Rubber Base) is a self-leveling fluid rubber indoor/outdoor waterproofing membrane that will cure as tough as a truck tire, remain permanently flexible, and can be applied at any thickness! It is a fluid rubber which will cure throughout its entire volume at ANY THICKNESS in 4 hrs or less at temperature of 70° F or higher. LRB will bond permanently to properly prepare concrete, wood, aluminum, steel, and some plastics, and most other standard building materials. LRB will not blister, crack, peel, or delaminate from exposure to extremes of ambient heat or cold as low as -45°F. It will withstand extreme Hydrostatic Pressure. LRB cures reliably even in extremely cold temperatures, never produces gas during curing, and does NOT generate heat as it cures. LRB is solvent-free, low VOC, low odor, molecularly welds materials, new to old.


LRB is applied over a surface that has been first primed with PermaFlex.

LRB (Liquid Rubber Base) can be ‘catalyzed’ or ‘activated’ using plain tap water. LRB will still remain as a self-leveling fluid and will cure solid in 4 hours or less at temperatures 70°F or higher (longer in cooler temps). As a fluid, LRB can be used to create a waterproof membrane at unlimited thickness. LRB can be used to self-level or smooth out a rough horizontal surface. LRB can be used to create ‘custom poured-in-place gaskets’ or form any solid shapes in as little as 5 minutes by using special catalysts.

Once LRB has been activated with water or Thickening Activator, it has a pot life of approximately 30 minutes. Unused and non-activated portions of opened LRB containers have a usable shelf life of 4-to-6 months. SANI-TRED® LRB is available in its natural off-white color, has a fluid consistency to 90 wt. gear oil or liquid Elmer’s Glue, and can be reduced using an approved solvent.

TAV™ (Thickening Activator) gives LRB (Liquid Rubber Base) great application versatility. TAV™ (Thickening Activator) is a thick, blue colored, inert, odor-free, gel-like additive specifically designed and formulated to be blended with LRB. TAV™ affects the viscosity of LRB, transforming it from a self-leveling build into a thickened 'caulk-like' mixture for vertical, horizontal, or inverted applications without sagging, running, or slumping.

  • LRB/TAV™ mixture is used to patch/seal any joint, seam, crack, hole, or rough areas and profile rough areas whether vertical, horizontal or inverted.
  • TAV™ is mixed with LRB at a 2:1 ratio. 2 parts LRB can be mixed with 1 part TAV™ to create the thickest possible mixture. Less TAV™ can be used to create a thinner, runnier mixture.
  • LRB/TAV™ mixture can be applied using a zip-loc bag, putty knife, trowel, flat squeegee, or most any common application tools.
