Waterproofing FAQ: Should I use a Torching Membrane or a Self Adhesive Membrane?

This article is part of a series about the waterproofing of buildings and constructions. It is relevant to residential and commercial buildings as well as civil engineering projects. It applies to both new build and for repairing an existing building. If you have a commercial project for which you require waterproofing products please contact us.

Both types of sheet membranes are commonly used to waterproof roofs and decks. Self-adhesive membranes are also used for waterproofing floors and foundations, where the membrane is sandwiched between layers of concrete. Sheet membranes are supplied in rolls and have a guaranteed thickness.

Reasons to use Self Adhesive Membranes

  1. They are applied without flame, therefore they are clean, easy and very safe to apply;
  2. They have a much greater elongation.

Reasons to use Torch-On Membranes

  1. As the underside of the sheet is melted by flame during application, it creates a seamless membrane, similar to liquid membranes;
  2. They are more robust and are thicker than Self Adhesive Membranes, and therefore are suitable for moderate foot traffic after application;
  3. All EABASSOC Torching Membranes can be left exposed on a roof as all the grades are UV resistant (with the possible exception of the sanded Standard SBS type).

More information about waterproofing products can be found in our articles comparing liquid applied and sheet membranes, and comparing water and solvent based liquid applied membranes.
