Liquid Waterproofing Membranes

Our liquid waterproofing membrane range covers 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. Liquid waterproofing membranes provide long-lasting defence against water ingress. Whether you manage leisure centres, office buildings, or industrial facilities, our liquid membrane range provides a dependable and versatile waterproofing option.

 

Understanding Liquid Waterproofing Membranes

Liquid waterproofing—often called liquid membranes or liquid rubber—uses modern chemistry to protect structures from water. Unlike sheet membranes, liquid systems 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 coating 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 Liquid Waterproofing Membranes

Liquid membranes 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, liquid membranes 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 liquid membranes 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.

Quality and Performance You Can Trust

Quality matters in waterproofing. Every Newton liquid membrane undergoes extensive testing and meets stringent industry standards. Many products hold BBA certification, giving you confidence in their performance in the UK’s challenging climate. Our technical team provides detailed guidance on system design, substrate preparation, and product selection. We consider conditions such as substrate type, exposure levels, and lifespan requirements to help you achieve the best results. We also supply complementary products—including primers, reinforcement fabrics, sealants, insulation layers, and drainage systems—to create a complete, compatible waterproofing solution.

 

Why Liquid Waterproofing Membranes Needed

Due to the UK’s persistent rainfall and large number of older buildings, reliable waterproofing is crucial. In addition, liquid systems 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 liquid membranes can safeguard structural integrity while also preserving the visual appeal of both historical and modern properties.
