Below-Grade Application

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 an innovative membrane called SikaShield® W which is bonded to the concrete substrate with a special cement-based adhesive.

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.
