Injection Resins
Water ingress through cracks, joints, or porous concrete can cause serious structural and safety issues. At Instant Waterproofing, we provide specialised injection resin solutions designed to stop leaks at the source and restore structural integrity.
Injection resins work by penetrating cracks and voids within the substrate and reacting to form a watertight seal. Depending on the situation, resins can be flexible, rigid, or expanding, making them suitable for a wide range of applications.
We use advanced injection technologies including:
• Polyurethane (PU) resins – hydrophobic or hydrophilic options that expand on contact with water, sealing even active leaks.
• Epoxy resins – rigid, high-strength materials that not only waterproof but also structurally repair and bond concrete.
• Acrylic resins – ultra-low viscosity, ideal for fine cracks, expansion joints, and large-scale soil stabilisation.
Common applications:
• Basement walls and lift pits
• Tunnels, car parks, and water tanks
• Retaining walls and concrete structures
• Remedial works where conventional waterproofing isn’t practical
Our technicians are trained in pressure injection methods and use specialised equipment to ensure thorough penetration and permanent results. This method is highly effective in both preventative maintenance and emergency leak repair.
