Bituthene® Liquid Membrane


Designed to complement sheet systems where liquid applied waterproofing is necessary to ensure watertight continuity. The compound cures to form a tough seamless rubber-like waterproof layer, suitable for pile terminations, pipe penetrations, membrane continuity through masonry, internal corners and difficult details.

Bituthene® Liquid Membrane should preferably be applied prior to the installation of the waterproofing membrane. It can also be used as a pointing surface sealer. It is compatible with dry Primer B1 and B2 and the compound used on all Bituthene® and Preprufe® systems.


Cementitious or Masonry substrates. Surfaces shall be dry and free from dust, dirt, grease and other contaminants.
