How Does It Work?

A resilient waterproofing membrane and effective drainage board work together for unsurpassed performance. Before you build another home with a basement, it’s important to consider how the basement will be protected from water damage. Damp proofing doesn’t guarantee a dry basement; it can crack and allow water to seep through the foundation. For a guaranteed dry basement, TUFF-N-DRI® Exterior Foundation Waterproofing System is your best choice.

TUFF-N-DRI® Exterior Foundation Waterproofing System consists of two components: TUFF-N-DRI® Waterproofing Membrane and WARM-N-DRI® Drainage Insulation Board.

TUFF-N-DRI® Membrane is a unique polymer-enhanced asphalt-based membrane which creates a highly electrometric, monolithic waterproof seal when applied to insulated concrete forms, poured concrete and block foundation walls. The membrane is tougher and more resilient than damp proofing materials commonly used on residential foundations. At the same time, it is priced very competitively with other damp proofing products.

WARM-N-DRI® Foundation Board, a rigid fiberglass board manufactured by Owens-Corning®, acts as a drainage medium to relieve hydrostatic pressure from the foundation walls. The board also reduces interior condensation, adds insulating value to the foundation, and protects the waterproofing membrane during backfilling and construction.

TUFF-N-DRI® Waterproofing System was introduced to the residential housing market in 1983. Our history includes over 175,000 satisfied homeowners nationwide. These homeowners are enjoying the benefits of dry, affordable, lower level living space, perfect for a home theater, an exercise room, kid's room, or a protective haven from severe weather.

Spray installation for seamless results.

TUFF-N-DRI® Membrane is spray applied to foundation walls, forming a continuous seal. There are no gaps or seams through which water can enter the foundation.

Excellent adhesion ensures bond.

TUFF-N-DRI® Membrane has a unique polymer enhancement that provides a strong bond to poured concrete, insulated concrete forms, parged masonry block, and unparged masonry block foundations.

Superior durability means long life.

Resilient TUFF-N-DRI® Membrane resists mold growth, bacterial and chemical attack. Unlike many damp proofing products, TUFF-N-DRI® on the outside guarantees a dry, cozy basement inside.
