Polyguard Underseal Underslab Membrane 4'x 50'

Polyguard Underseal Underslab Membrane 4’x 50’

Underseal® Underslab Membrane is a tough, 85-mil pre-concrete pour waterproofing membrane/vapor barrier designed to virtually eliminate water and vapor transmission through concrete slabs on grade. In addition to protecting floor finishes and indoor air quality, Underseal® Underslab Membrane also acts as a barrier to methane and radon gas.

Features & Benefits:

• Superior Protection: 3-layer composite membrane
• Superior Puncture Resistance: Higher than current Class A Vapor Barrier requirements (2200 grams, or under 5 pounds)
• Superior Resistance to Water Migration: Eliminates water and vapor migration by forming a strong mechanical bond to the concrete
• Superior Adhesive Bond: Creates a strong adhesive bond when the static load and thermal reactive heat of the concrete slab causing sealant/adhesive compound to have intimate contact with the concrete surface
• Superior Adaptability: Flexible material that adapts to job site irregularities for ease of installation
• Superior Joints: Fully-adhering, watertight laps
• Superior Crack Protection: Stress-absorbing and elongation properties to maintain a watertight seal to the structure if cracks develop in the base material or the slab
• Superior Barrier: Acts as a barrier against toxic contaminants methane and radon gas, which may attempt to enter the structure through cracks in the concrete
