Cementitious Tanking Slurries & Renders

Our cementitious tanking slurries & renders cover every substrate and application. The options span from flexible liquid rubber systems to durable cementitious coatings. Each solution suits both retained structures and covered and exposed decks. Alongside our membranes, we also supply collomix mixing equipment and flexible construction joint waterproofing products.

In the UK’s rapidly changing climate, reliable moisture protection is crucial for both residential and commercial buildings. Cementitious tanking slurries & renders provide long-lasting defence against water ingress. Whether you manage leisure centres, office buildings, or industrial facilities, our cementitious tanking slurries & renders provide a dependable and versatile waterproofing option.

Understanding Cementitious Tanking Slurries & Renders

Unlike sheet membranes, slurries & renders create a seamless coating that bonds to a wide range of substrates, including concrete, masonry, plywood, and existing bitumen.

Their versatility makes them ideal for roofs, balconies, foundation walls, and internal flooring. Once applied, the slurry/render forms a flexible, continuous barrier that prevents water ingress while still allowing vapour to escape. This reduces trapped moisture and helps protect the structure over the long term.

Advantages of Cementitious Tanking Slurries & Renders

Cementitious tanking slurries & renders offer several key advantages over traditional waterproofing methods. To begin with, they are simple to apply. Installers can use rollers, brushes, or spray equipment to create a fast and efficient coating. As a result, projects move quickly, and labour costs often fall. Additionally, the slurries & renders offer seamless protection. Because there are no joints, there are fewer weak points where water could penetrate. Furthermore, they adapt well to complex shapes, detailing, and irregular surfaces, which ensures full coverage even in difficult areas.

High-quality cementitious tanking slurries & renders also offer excellent durability. In fact, many systems deliver 25+ years of performance when they are correctly applied and maintained. Although the initial cost may be higher than that of basic alternatives, the long-term reliability and reduced maintenance make liquid systems a smart, cost-effective investment.

What Are Cementitious Tanking Slurries & Renders?

Due to the UK’s persistent rainfall and large number of older buildings, reliable waterproofing is crucial. In addition, slurries & renders create a seamless barrier that protects heritage buildings from moisture damage. Their flexibility makes them suitable for roofs, balconies, basements, podium decks, and more. As a result, property owners who select modern slurries & renders can safeguard structural integrity while also preserving the visual appeal of both historical and modern properties.
