Grove Residentials by NASHAMA is a contemporary residential development in Town Square, Dubai, with ground floor, parking level, fifteen floors and roof. The project required durable resistance to water penetration in its concrete structure. 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. As a Permeability Reducing Admixture for Hydrostatic Conditions (PRAH), it protects concrete against both positive and negative water pressure of up to 14 bar. Because it becomes an integral part of the concrete, protection continues even if the surface is damaged, and its long-term reactivity lets hairline cracks of up to 0.5 mm self-seal when they come into contact with water. It also increases resistance to water, chloride and sulfate ingress and to chemical attack, while keeping the concrete vapour-permeable so it can breathe.
