- 48" x 50' Roll, 85 Mil Thick, 80 Lb Tensile Strength, Asphaltic Odor, Solid, Black/White Underseal®/UNDERSLAB Sheet Waterproofing Membrane (25 per Pallet)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 and elevator pitts. In addition to protecting floor finishes and indoor air quality, Underseal® Underslab Membrane also acts as a barrier to methane and radon gas. Underseal® Underslab Membrane provides a continuous seal underneath the foundation slab. A strong mechanical bond is developed between the membrane and concrete at the time of pouring as the concrete intermingles with the fibers of the nonwoven geotextile. A strong adhesive bond is created when the static load and thermal reactive heat of the concrete slab causes sealant/adhesive compound to have an intimate contact with the concrete surface preventing water migration. Underseal® Underslab Membrane is typically installed horizontally over a prepared subbase such as compacted soil, mud slab or #57 stone. 85 mil Underseal® Underslab can also be used in vertical applications.
- Lasting Durability: Tough 3-Layer Composite Membrane - Technology that has Stood the Test of Time
- Outstanding Puncture Resistance: 2 Times Higher than the New AC 527 Building Code Requirement - Better Protection against Backfill Damage
- Strong Mechanical Bond: Our Inner Fiberous Layer Embeds Itself into the Cured Concrete Creating a Very Strong Mechanical Bond - Ensures Our Waterproofing System will Stay in Place as the Building and Outside Soil Move During the Building's Lifetime
- Resistant to Water Migration: An Adhesive Bond is Created when Heat from the Concrete Wall While Curing, Causes Our Compound to Melt onto the Concrete's Positive Side Surface Creating a Continuous Sealed Structure
- Jobsite Adaptability: Flexible Material that Adapts to Job Site Irregularities for Ease of Installation
- Superior Joints: Strong Laps Seams Create a Long Lasting, Water Tight System - Outperforms the New AC 527 Standard (ASTM 1876) by More than 40%
- Crack Protection: Blindside is Thicker than Most Non-Asphalt Based Competitive Products which Gives it the Stress-Absorbing and Elongation Properties to Maintain a Water Tight Seal
- Helps Manage Harmful Gases: Acts as a Barrier against Toxic Contaminants Methane and Radon Gas, Which May Attempt to Enter the Structure through Cracks in the Concrete
