Waterproofing
Overview
A vital part of any project
Normet’s proven waterproofing solutions have been used for over 30 years in tunnelling and civil engineering projects to prevent water ingress or egress.
Concrete waterproofing is essential in any area exposed to a damp or wet environment to control or prevent water ingress. Our comprehensive portfolio of resins and grouts include polyurethane and acrylic alternatives and a variety of gel times and cure rates suitable for any application. Normet TamSeal, TamCrete and TamSeal waterproofing solutions are highly stable, chemically resistant, durable, and backed up by a complete range of accessories such as pumps, packers, and additives.
All of our products use the latest high-performance technology for safe, efficient and environmentally friendly use, helping to reduce project costs and carbon emissions. Wherever water needs to be detained or retained, Normet has a concrete waterproofing admixture, resin or membrane to do it.

Waterproofing Products
Spray Applied Waterproofing
TamSeal spray-applied waterproofing membranes are engineered to resist water ingress and waterborne contaminants, delivering long-lasting protection for underground structures. These membranes exhibit high resistance to both positive and negative water pressure and are ideal for use in tunnels, basements, and water-retaining structures. Easy to apply in varying thicknesses, TamSeal systems ensure seamless coverage, fast installation, and exceptional durability—even in complex geometries and aggressive environments.
Liquid Applied Coatings - Cement Based
Normet’s cement-based liquid applied coatings are polymer-enhanced for superior waterproofing. Easy and safe to use, they resist both positive and negative water pressure. Naturally compatible with concrete, these coatings form strong, impermeable barriers using advanced chemical technology.
Liquid Applied Waterproofing - Polymer Based
Normet’s TamSeal polymer-based waterproofing systems are engineered for extreme environments. They resist chemicals, seawater, sewage, and waterborne contaminants like chlorides and sulfates. With solar heat resistance and flexible or elastomeric properties, TamSeal coatings offer durable protection and easy application.
Normet Sheet Waterproofing Membranes
Normet’s proven sheet waterproofing membranes are engineered to protect large concrete surfaces such as foundation slabs, retaining walls, and tunnels. Designed for diverse environments and applications, these membranes deliver reliable performance and superior durability.
Penetrative Waterproofing Sealers
Normet’s penetrative waterproofing sealers include advanced admixtures and chemical systems designed for deep concrete protection. The range features silane-siloxane, silicate, and crystalline technologies, offering long-lasting resistance against water ingress and environmental contaminants.
Concrete Joint Waterproofing
Normet specializes in advanced waterproofing solutions for concrete joints. Our re-injectable tube systems deliver water-stopping grouts and gels to critical areas beneath concrete surfaces. Combined with hydrophilic waterstops and joint treatments, these systems offer versatile and durable protection for a wide range of applications.
Water Plugging
Normet’s TamCrete Plug and PolyPlug are rapid-setting, single-component mortars designed to stop water ingress in critical concrete structures. These solutions harden even under constant water pressure, making them ideal for sealing leaks in basements, foundations, substructures, and tunnels.
