Waterproofing mortars are used to protect structures against water infiltration. They are supplied as ready-to-use solutions to seal against damp soil, seepage and percolating water. Waterproofing mortars are often applied in basements, water reservoirs, water retaining structures and other engineering structures as well as beneath tiling for swimming pools, balconies, bathrooms and kitchens.

How to Select an Injection Material to Seal Leaks?

Leaks in concrete, masonry and natural stone structures can often be securely sealed and waterproofed by injection. However, to make leaking structures watertight for the long term, it’s essential to select the right injection material. On the basis of our extensive technical and practical experience, we have prepared a guide which will help you choose the optimal injection solution for your project requirements.

Watertight Concrete System

Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.
