- 48" x 50' Roll, 73 Mil Thick, 80 Lb Tensile Strength, Asphaltic Odor, Solid, Black/White Underseal®/BLINDSIDE™ Sheet Waterproofing Membrane (25 per Pallet)Underseal® Blindside™ Membrane is a tough, 73-mil pre-concrete pour waterproofing membrane/vapor barrier designed to virtually eliminate water and vapor transmission through below grade concrete walls. Underseal® Blindside™ Membrane is used as a waterproofing membrane where vertical, positive-side waterproofing is required to be installed before the foundation walls are poured. 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. With both a mechanical and adhesive bond, the concrete will be tightly sealed and bonded to the membrane, creating superior protection against moisture intrusion. 73-mil Underseal® Blindside™ can also be used in certain horizontal applications. Contact Polyguard for more information.
- 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
