Sydney_Opera_House.jpg GCP’s robust waterproofing product offering provides reliable solutions for all waterproofing designs and conditions. GCP invented the self-adhered waterproofing membranes more than 50 years ago and has been the leader in this category ever since.

Structural and foundation waterproofing, including above- and below-ground waterproofing, is a critically important component of any commercial building structure. Depending on its application, below-ground waterproofing could be pre-applied or post-applied. Post-applied waterproofing membranes are applied after the installation of the concrete walls. Pre-applied waterproofing gets applied before the foundation is poured. These membranes may be used in wet environments or under wet conditions to a certain depth in order to promote soil stabilisation and to provide foundation waterproofing. A pre-applied application must adhere to a strict set of installation guidelines; once the membrane has been installed, repair or maintenance is very difficult. Post-applied below-ground waterproofing needs to be well-adhered and sealed to the structure, providing flexibility to accommodate structural movements. Above-ground waterproofing installation can be an arduous task due to curves, corners, complex shapes and geometries, requiring a reliable waterproofing membrane.

GCP offers advanced waterproofing membranes and technologies for virtually all above- and below-ground commercial applications. Our brands, Bituthene®, Preprufe®, Aquagard®, Chemspray®, Adprufe®, Hydroduct®, and Adcor®, include self-adhesive sheet-applied and liquid-applied waterproofing membranes, integral waterproofing, cementitious waterproofing, drainage composites and waterstops. GCP has expanded its portfolio with the addition of remedial waterproofing, concrete protection and repair products.

Our innovations in structural waterproofing can be found in signature buildings and projects around the world, protecting their integrity for more than 50 years.
