Waterproofing Joints
Waterproofing joints are vital for safeguarding concrete structures from water ingress and damage. Whether sealing cracks, expansions, or movement-prone areas, these joints are essential for long-term durability in structures like buildings, tunnels, and roadworks. Rawlins Paints offers an extensive range of sealants, adhesives, and sealing profiles designed to meet the challenges of these demanding environments.
Fosroc Supercast SW
Fosroc Supercast SW are swellable waterstops made from high performance synthetic elastomer strips for in-situ concrete, which have a delayed swell action which helps prevent pre-swell during wet site conditions. Expansion of the waterstop creates a positive pressure against the faces of the concrete joint, thus preventing water passing...
Fosroc Supercast SW Adhesive
Fosroc Supercast SW Adhesive is an adhesive used to bond swellable waterstops such as the Supercast SW waterstops to concrete. The Supercast SW range consists of swellable waterstops; Supercast SW formed sections, Supercast SWX gun-applied paste and Supercast SW Adhesive. More Information Delivery Info

Defending Against Water: The Role of Waterproofing Joints
Waterproofing joints are critical in protecting concrete structures from the damaging effects of water infiltration. These joints are designed to seal cracks, expansions, and other vulnerable areas, preventing water from penetrating and weakening the structure. Used in demanding environments such as tunnels, buildings, and roadworks, waterproofing joints ensure that concrete can withstand both moisture and movement without deterioration.
Why Are Waterproofing Joints Essential?
Concrete is a dynamic material that expands, contracts, and develops cracks over time. Waterproofing joints address these natural movements, ensuring that water does not find its way inside. Without these joints, water ingress can compromise the integrity of concrete structures, leading to costly repairs or failures. Sealants, adhesives, and sealing profiles provide a durable barrier that preserves structural strength even in high-stress areas.
Where Can Waterproofing Joints Be Applied?
- Tunnels and Roadways: These high-traffic areas are prone to cracking and movement, making effective waterproofing essential to prevent structural damage.
- Buildings and Foundations: Expansion joints in concrete walls and foundations require sealing to protect against water penetration.
- Hydraulic Structures: Water-retaining structures, such as dams and water treatment plants, demand specialised waterproofing to secure long-term performance.
