Residential Building (B+G+9+Roof), Al Barsha South by MARQUIS

About the Project

The MARQUIS residential building in Al Barsha South, Dubai, comprises a basement, ground floor, nine floors and roof. The structure needed durable waterproofing that would perform under varying environmental conditions. Baumerk Crystal PW 25 crystalline waterproofing admixture was added directly to the concrete mix to provide integral protection against water ingress and hydrostatic pressure. Eliminating external waterproofing systems streamlined construction, reduced maintenance needs and ensured reliable, long-lasting performance.

The waterproofing performance of this project is built on the properties of Baumerk Crystal PW 25. Crystal PW 25 is a hydrophilic crystalline waterproofing admixture that reacts with cement and water to start a catalytic process, forming a protective crystalline network inside the concrete's pores, capillaries and cracks and significantly reducing permeability. Supplied as a powder, it is added at the batch plant, in the ready-mix truck or at the precast plant at 0.8–1.0% by weight of cement, and it is compatible with all cement types, supplementary cementitious materials, admixtures and fibres. It is non-toxic, safe for use in water tanks and removes the need for additional waterproofing applications. As a Permeability Reducing Admixture for Hydrostatic Conditions (PRAH), it protects concrete against both positive and negative water pressure of up to 14 bar.
