Description

The RESISTO Below-Grade Drainage Board is a high-performance, dimpled high-density polyethylene (HDPE) membrane designed to provide superior protection for foundation walls and basement floors. By creating a continuous air gap and drainage path, it effectively manages soil moisture and prevents hydrostatic pressure buildup against your structure.

• High-Density Polyethylene (HDPE) Construction: Engineered from rugged, durable HDPE that is resistant to soil chemicals, alkalis, and acids, ensuring long-term underground performance.

• Effective Hydrostatic Pressure Relief: The dimpled design creates an air space between the soil and the wall, allowing water to flow freely to the footing tile/drainage system.

• Waterproof Vapor Barrier: Acts as an impermeable barrier that keeps damp soil away from the foundation and prevents moisture vapor from migrating into living spaces.

• Eco-Friendly Material: Composed of approximately 85% recycled content, making it a sustainable choice for green building projects without sacrificing strength.

• Crack Bridging Ability: Easily bridges settlement cracks up to 1/4 inch (6 mm), maintaining a dry interior even as foundations shift over time.

• All-Weather Installation: Unlike liquid-applied membranes, this board can be installed in any weather condition, including extreme cold or rain, preventing project delays.

• Versatile Substrate Compatibility: Suitable for use on cast-in-place concrete, masonry blocks, preserved wood foundations (PWF), and insulated concrete forms (ICF).

• Foundation Longevity: Allows concrete to “breathe” by controlling humidity and reducing the risk of mold, mildew, and freeze-thaw damage to the foundation wall.
