Proofex Engage


The original, innovative,

mechanically bonded,

pre-applied below ground

waterproofing system

Proofex Engage

In projects where piled walls are used as the construction method or where ground settlement is expected, Fosroc recognised waterproofing product performance could be improved. An innovative pre-applied waterproofing membrane was developed to adhere fully to the structural concrete. This would give the benefit of assured waterproofing integrity, even if settlement occurred. An important design feature of this Fosroc membrane was to develop the system using a smart cell matrix, which mechanically bonds to fresh concrete. This bonding technique is suited for actual project site conditions where dirt and grim are present; the cell matrix can be easily air-cleaned prior to concrete pouring, coupled with its superior robustness, comforts clients during the waterproofing installation.

Proofex Engage Features

Proofex Engage Benefits

Fosroc understands there are various complexities and time/cost constraints on each project site. Proofex Engage, with its packaged accessories, makes designing and constructing below-ground waterproofing systems easy.

Proofex Engage has a long, successful track record, spanning over 17 years. giving owners and designers peace of mind that their below-ground asset is fully protected against the harmful effects of water ingress. The system is independently certified to the BBA and complies with recognised worldwide standards. Fosroc local specification managers are available to assist you in specification writing and creation of bespoke project details, including CAD drawings. The Proofex Engage system has excellent holistic cost benefits due to its single layer quick, easy installation method. No protection screed is required, which saves time and money. This also negates the need for many concrete mixer trucks, which saves fuel and is more environment friendly. The smart anti-tracking cell matrix in Proofex Engage is robust, even for highly congested rebar configurations and thick section concrete pours. The matrix assures a tenacious mechanical bond to fresh concrete and is independently certified for non-water tracking to over 7 bar water pressure. Some buildings over their lifetime can be subjected to minor concrete cracking, which can cause water ingress; however, due to Proofex Engage’s excellent tensile and elongation properties, it will retain its waterproof integrity, spanning concrete cracks even up to 3mm.

Proofex Engage has been successfully installed throughout the world in many project site conditions. From cold to hot climates, small to large mega projects, the system has proven its suitability for easy application and assured durability. The large 38m2 roll size is easily kicked-out in rapid speed. The cell matrix is robust; when tested for puncture resistance in accordance with EN12691, a drop height value of over 1.5m is achieved. Fosroc has a tried and tested solution at pile heads involving compatible waterproof epoxy grout, which interlocks with the Proofex Engage cell matrix, resulting in continuity of waterproofing integrity and strength at these critical locations. Fosroc not only supplies quality proven systems, but can provide on-site application training and guidance for complicated details.

Proofex Engage Track Record

Fosroc's vast experience in providing waterproofing solutions to many famous structures around the world, such as the Burj Al Arub in Dubai, has been built on a broad range of products and technical advice/guidance.

Proofex Engage, our innovative pre-applied waterproofing system, has been successfully installed below-ground in many projects around the world, ensuring structural integrity and long-term durability of the structure. A recent example being the Wynn Palace project in Macau, where the site was built on re-claimed contaminated land, and the waterproofing system had to be both water and gasproof. A full below-ground water/gasproof system, based on Proofex Engage, was chosen, which also included waterstops and drainage membranes, and when combined with Fosroc’s onsite support and technical guidance, resulted in a successful project.

Fosroc can assist you in achieving the best waterproofing solution for your project.
