SBS Modified Bitumen Waterproofing Membrane: What to Know

Overview

BXI SBS Modified Bitumen Waterproofing Membrane Roll is described as a torch-on asphalt roofing material and self-healing flashing sealant. Also, it is described for outdoor roof, foundation, and ice and water shield use.

This roll is described as a flexible membrane that can be applied with torch heating. However, it is also described as able to be adhered with waterproof glue.

Realistic expectations: The membrane is described as intended to support waterproofing and sealing in leak repair projects. Also, the dense surface is described as creating a water-tight barrier. It is described as functioning in hot and cold environments without cracking or melting. In addition, it is described as remaining functional at temperatures as low as -20°C (-4°F).

Key takeaways

  • Comes in a 13 in x 8.2 ft roll with 1/8” thickness and 8.86 square feet coverage.
  • Uses SBS polymer modified bitumen with a cross-textured surface described for torch application and even heating.
  • Supports two application ways: torch heating with rolling and compressing, or adhering with waterproof glue.
  • Describes dual waterproofing using a dense surface water-tight barrier and heated fusion into cracks.
  • Describes functioning in hot and cold environments without cracking or melting, and down to -20°C (-4°F).
  • Buyers commonly describe the roll as thick or dense, and torch application as melting evenly and sticking down well.

What the product is designed to do

This product is described as an SBS modified bitumen flashing sealant underlayment intended to provide waterproofing and sealing. Also, the membrane is described as creating a water-tight barrier through a dense surface.

When heated, it is described as deeply penetrating into cracks of the substrate until the materials fuse together for powerful, lasting adhesion. In addition, it is described as having a self-healing feature for long-term outdoor use.

The self-healing feature is described as the material flowing around minor damage to form new bonds and seals. Next, this behavior is described as restoring waterproof protection rapidly.

For a direct product reference, use SBS modified bitumen waterproofing membrane roll in the same roll format. Also, the described use range includes roofs, decks, and concrete surfaces.
