SikaShield® bituminous membranes are an excellent solution for waterproofing below-ground structures due to its consistency and high-quality performance.
In addition to torch-applied and self-adhesive membranes, Sika has a membrane called SikaShield® W which is bonded to the concrete substrate with a special cement-based adhesive. Truly an innovative solution, it combines the advantages of a bituminous membrane with the universal application of a cementitious product.
An Innovation in Bitumen Application
Benefits for Below-Grade Application
Can be applied on fresh concrete or damp surfaces
Application in confined spaces and/or walls without torch or solvent-based primers
Minimum substrate preparation
Excellent adhesion to the concrete surface
Wet-Applied Bituminous Membrane
SikaShield® W is a unique system developed to overcome the most common challenges in waterproofing below-ground structures. It provides an effective, easy and simple application for all seasons and job requirements.
The self-priming, cement-based adhesive acts as a levelling compound and sealing adhesive, resulting in a strong, lasting bond between the concrete substrate and the membrane. This bond helps to avoid any lateral water migration and reduce the risk of leakages.
