Waterproof Your Basement This Weekend (No Contractor Needed)

The SANI-TRED System is a three-product liquid rubber waterproofing solution that works together to create permanent, seamless protection for basements and concrete surfaces:

PermaFlex – A thick liquid rubber coating that penetrates up to 1.5 inches deep into concrete, creating microscopic rubber "o-rings" that anchor from within. Used as both primer and topcoat. (Coverage: 240 sq ft per gallon)

LRB (Liquid Rubber Base) – A self-leveling liquid rubber for filling cracks, joints, and depressions. Cures to solid rubber in 4 hours at any thickness with 600% elongation.

TAV (Thickening Activator) – Blends with LRB to create a caulk-like consistency for vertical application on walls and wall-floor joints without sagging.

Together, these three products join all surfaces seamlessly with no remaining cracks or joints. Unlike paint or sealants, SANI-TRED permanently bonds to concrete, never hardens or becomes brittle, and stretches with your foundation. The system carries a lifetime warranty and eliminates the need for excavation, drainage systems, or sump pumps.

SANI-TRED averages $1.24 per square foot, making a typical 800 sq ft basement project cost around $1,000-$3,000 (depending on substrate and condition) for complete waterproofing—compared to $10,000-$15,000+ for traditional contractor methods with excavation, drainage systems, and sump pumps. For example, a 20'x40' basement with 8' walls costs approximately $2,000-2,500 with SANI-TRED versus $14,600 with conventional systems.

No. PermaFlex, LRB, and TAV are all solvent-free and low-VOC, making them as odor-free as latex paint—safe for indoor use without overwhelming fumes. If you choose to use solvents to thin products (optional), we recommend PPE and adequate ventilation. Have questions about application or ventilation? Call us at 1-866-784-3308 before starting your project.

SANI-TRED comes with a Limited Lifetime Warranty for the life of the structure when properly applied.

The warranty covers both interior and exterior applications, including exposure to high-pressure washing (up to 3,000 PSI) and perpetual water contact.

What's covered: Product defects and performance failures when installed according to our instructions on properly prepared surfaces.

What's excluded: Improper surface preparation, application over existing inferior coatings, mixing with unapproved products, extreme heat damage (over 250°F), and commercial/industrial projects (which have custom warranties).
