Pool Decks

Pool-deck applications are found in multiple facilities, which include pools and spas, aquaparks, reservoirs, lagoons, and fountains.

The waterproofing of pool decks not only protects the structure but also the people who are enjoying pools from injuries, as slips and falls by bare-footed people on wet pool decks are common. Appearances of tiny cracks are common signs of wear and tear on pool decks. Water causes erosion that occurs gradually, leading to inconspicuous cracks developing into bigger problems. As water seeps under the slab, it softens and weakens the underlying soil, compromising the slab integrity. A concrete coating shields the surface of pool decks from water penetration, sun exposure, and the corrosive effect on the concrete of wind over time, which blasts sand particles across its surface.

Holderchem supplies a range of products for pool decks, which include the following:

• Waterproofers that integrally waterproof concrete mortar and other cementitious structures. These crystalline technology-based products penetrate fast, depending on the concrete matrix porosity, deeply in the concrete and mortar structures, up to a 10 cm depth, through capillary tracts to permanently enhance physical properties. They chemically react to block moisture ingress and expel embedded chlorides. They convert free water-soluble calcium hydroxide into a dense crystalline network of insoluble calcium silicate hydrate gel within the concrete pore structure that seals and densifies the concrete, improving resistance to chemicals, and protecting reinforcing steel from corrosion. They significantly reduce the migration of efflorescence, sustain mold, mildew, and fungal growth. They can be applied on both the negative and positive sides. They significantly reduce moisture vapor emissions.
• Two-component, polymer-modified, highly flexible, cementitious membrane for the waterproofing and protection of concrete, masonry, and many other types of construction materials and substrates, which are designed for exterior or interior applications, and above or below grade structures. These are used and applied to horizontal, vertical and overhead surfaces to protect concrete against de-icing salts, chlorides and sulfates, and prevent concrete carbonation. They form breathable vapor permeable membranes with excellent resistance to impact, abrasion and wear.
