DELTA MS Underslab

The Problem

Floor slabs collect moisture and mold when composed of porous concrete. Proper moisture control is necessary to protect a building's foundation and provide longevity. A sub-base course prevents concrete from pulling water up from the dirt and seeping through walls, floor, and joints.

The Solution

DELTA-MS UNDERSLAB provides reliable, long-term protection for permanently dry concrete slabs. It is a high-performance vapor retarder and sub-base course with high compressive strength, also acting as a capillary break for long-term protection from rising moisture.

Product Details

• Dimple board
• Middle layer manufactured with an exclusive co-extrusion process using 60% recycled High-Density Polyethylene (HDPE)
• Two thin outer layers composed of a specific grade of virgin HDPE

Product Benefits

• Vapor retarder; protects the foundation from rising moisture
• Outstanding compressive strength and impact resistance
• Unrivaled sustainability and long-term performance
• Acts as a capillary break under the slab
• Reduces or eliminates the need for expensive gravel
• Composed of 60% recycled HDPE - environmentally friendly
• Outer virgin HDPE layers protect the recycled core from polymer degradation due to oxidation, acidic soils, or alkalinity from concrete
• Stabilized against chemical and environmental stress cracking
• Tough and durable - the dimpled sheet endures jobsite installation
• Easy to unroll and install - no equipment or additional excavation required
