Waterproof Everything!
Waterproofings are our core competence
01
Modern Waterproofing
Modern waterproofing systems provide robust, long-lasting protection for a wide variety of structures, combining advanced chemistry with practical application methods. Products like Remmers MB 2K, a flexible waterproofing compound, and Kiesol, a reliable deep-penetrating primer and moisture blocker, work together to create highly durable, crack-bridging barriers against moisture ingress. These systems are designed for efficiency and versatility, making them suitable for both new construction and refurbishment projects.
A wide range of additional modern waterproofing products is also available to suit different substrates and performance requirements.
03
Rising Damp Protection
Effective rising damp protection needs solutions that tackle moisture at its source while minimising damage to the fabric of the building. The Contec IPE is a non-invasive rising damp elimination system that uses an electromagnetic polarity inverter to interrupt the driving forces that encourage moisture to rise in masonry, offering a drill-free option for buildings where minimal intervention is essential. By contrast, Kiesol C & Injection Cream 80 is a proven injection chemical that forms a horizontal moisture-repellent barrier within the wall, preventing further capillary rise while maintaining the wall’s breathability.
Both approaches can be used individually or as part of a tailored programme depending on the severity and cause of damp. They are suitable for residential, commercial and historic buildings where preserving fabric and appearance is important, and their complementary natures give specifiers practical, less-invasive choices for restoring dry, stable conditions in masonry walls.
02
Roof Waterproofing
Roof waterproofing solutions are engineered to deliver exceptional protection against weathering, standing water, and long-term UV exposure. The Remmers MB PUReactive range offers high-performance, liquid-applied membranes that form a seamless, fully bonded coating capable of withstanding extreme conditions. These polyurethane-based systems cure rapidly and adhere to various roof surfaces, making installation efficient and minimally disruptive.
The MB PUReactive range is well-suited for walkways, flat and pitched roofs, providing a durable, flexible barrier that moves with the building to prevent cracking and water ingress. Its versatility and reliability make it an excellent choice for maintaining the longevity of modern roofing structures.
04
Heritage Waterproofing
Heritage waterproofing requires specialised materials that respect historic fabric while delivering effective moisture control. Rinzaffo Controspinta MGN, a high-quality renovation plaster designed for counter-pressure moisture situations, provides a breathable and salt-resistant solution ideally suited for conservation work. It allows trapped moisture to escape while preventing further water penetration, helping maintain the longevity of traditional structures.
This system is particularly effective in older masonry buildings where conventional waterproofing methods may be too rigid or invasive. Rinzaffo Controspinta MGN supports long-term preservation by offering reliable protection without compromising the character or integrity of historic materials.
What water protection do we offer?
Waterproof, damp-proof, and water-repellent.
Our waterproofing solutions deliver innovative, versatile, and highly effective protection against moisture and water ingress. Designed to safeguard structures while preserving their integrity, these systems are suitable for both modern construction and sensitive historic buildings, ensuring long-lasting durability without compromising aesthetics.
Traditional Waterproofing
Traditional waterproofing relies on rigid grouts and coatings to create a strong, impermeable barrier against water ingress. Products like Remmers WP Sulfatex and WP DS Levell provide durable, mineral-based protection that is ideal for foundations, basements, and masonry where a hard, long-lasting layer is required. These systems are trusted for their structural integrity and proven performance in a wide range of applications.
Modern Waterproofing
Modern waterproofing systems focus on flexibility, adhesion, and ease of application to protect structures against moisture and environmental stresses. Remmers MB 2K, a two-component, flexible mineral-based waterproofing solution, forms a seamless, crack-bridging barrier, making it ideal for both new builds and refurbishment projects. These systems adapt to the substrate while maintaining long-term durability.
Liquid Roofing
Liquid roofing systems provide a seamless, fully bonded protective layer that resists water, UV exposure, and temperature fluctuations. The Remmers MB PUReactive range is a high-performance, polyurethane-based solution that cures rapidly to form a flexible, weatherproof membrane, suitable for flat and pitched roofs alike. Its versatility ensures reliable long-term protection for a variety of roofing structures.
Impregnation Sealers
Impregnation sealers penetrate deeply into masonry to provide water repellency while maintaining vapor permeability. Products such as Funcosil SNL, OFS, AG, and Contec USP 100 ect.. protect surfaces from moisture, staining, and weathering without altering appearance. They are ideal for facades, historic buildings, and exposed masonry requiring long-lasting protection.
Heritage Waterproofing
Heritage waterproofing requires solutions that protect against moisture while respecting historic fabric. Rinzaffo Controspinta MGN is a breathable, salt-resistant renovation roman lime plaster that manages moisture under pressure, allowing trapped water to escape while preventing further ingress. It provides reliable protection for historic masonry without compromising character or integrity.
Non Invasive & Sensitive Damp Proofing
Non-invasive damp proofing uses advanced electromagnetic and geomagnetic technologies to reduce rising damp without drilling or chemical injection. Systems like IPE and IPG polarity inverters modify the natural forces driving moisture, offering a sensitive solution that preserves building fabric while effectively controlling damp in both modern and historic structures.
Rising Damp Eliminator
Rising damp requires targeted systems that block or eliminate moisture moving upward through masonry. Non-invasive technologies like the Contec IPE and IPG polarity inverters disrupt the electromagnetic and geomagnetic forces that drive capillary rise, providing drill-free, fabric-friendly solutions ideal for sensitive or historic buildings. For more traditional treatment, Kiesol C injection forms a horizontal chemical barrier within the wall, preventing further moisture migration while maintaining breathability. Together, these systems offer adaptable and reliable protection for a wide range of structures.
Tanking Systems
Tanking systems create a durable, continuous waterproof barrier for both interior and exterior applications, protecting structures exposed to hydrostatic pressure. Remmers MB 2K, a flexible, crack-bridging waterproofing system, is ideal for tanking walls, basements, retaining structures, and underground rooms, forming a seamless and highly resilient coating. Whether applied inside or out, modern tanking solutions ensure long-term stability and dry conditions even in demanding below-ground environments.
Injection Waterproofing
Injection systems are designed to treat rising damp and prevent water ingress by creating chemical barriers within masonry. Kiesol C and Injection Cream 80 are highly effective options, forming horizontal moisture-resistant layers that block capillary action while preserving wall breathability. These systems provide a reliable solution for damp control in both modern and historic buildings.
Drinking Water Tanks / Silos
Concrete water silos storing drinking water require waterproofing materials that are both structurally reliable and certified safe for potable environments. Remmers WP Sulfatex provides a robust, mineral-based coating that adheres strongly to concrete, offering long-lasting protection while meeting the strict hygiene requirements for potable water storage. Its resistance to constant immersion and compatibility with drinking water standards make it an excellent choice for safeguarding concrete silos and maintaining water purity.
Plugging mortar
Plugging mortars provide immediate, targeted water control by sealing leaks and local water ingress. Products such as Remmers WP RH Rapid react quickly to stop water at the source, making them ideal for emergency repairs, leaks in basements, tunnels, or masonry requiring rapid intervention.
