Should I use a Liquid Waterproof Coating or a Sheet Membrane?

Sheet Membranes

Torch Applied or Self-Adhesive Sheet Membranes give a guaranteed membrane thickness, which is not dependent on the skill of the applicator. However, they do have an overlapping joint which, if not applied properly, can allow water to penetrate.

Liquid Applied Membranes

Liquid waterproof coatings, such as EABASSOC RBE, TPU or Spraytec, create a uniform coverage without creases or seams. The thickness and the amount applied can be varied and they are generally easy to apply by brush, squeegee, roller or spraygun. They are however, more sensitive to good application as regards maintaining a uniform and correct thickness.

The choice of sheet or liquid waterproofing membrane really depends on personal preference as they are used for similar applications, for example waterproofing roofs, and they both provide effective waterproofing if correctly applied.
