Sika provides a complete solution to make buildings that are waterproof, ranging from underground structures, bathrooms, swimming pools to the roof.

Waterproofing protects structures against water infiltration which can cause expensive and irreversible damage. It is mostly invisible after construction is completed. Every day the basement of a building, or the outermost layer of a tunnel, is exposed to intense fluctuations in moisture levels and temperatures, all contributing to its deterioration. Count on Sika to provide long-lasting waterproof systems to protect your project.

Sika has over
100 years
of waterproofing experience, since the first Sika waterproofing product was invented in 1910.
With 50 years of experience, Sikadur Combiflex SG System, the leading solution in adhered tapes, is sold in nearly 90 countries where more than
40,000 km
of tapes have been applied!
3.3 million
square meters of Sikaplan® waterproofing membrane, equivalent to about 330 football fields, was used on the Gotthard Base Tunnel, the longest railway tunnel in the world.

Liquid-Applied Membrane

Liquid-applied membrane (LAM) is a monolithic, fully-bonded, liquid-based coating suitable for many waterproofing and roofing applications. The coating cures to form a rubber-like elastomeric waterproof membrane and may be applied over many substrates, including asphalt, bitumen and concrete.

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.

Considerations for Facade Joint Design

The facade is the face of buildings. In contemporary architecture, the facade is of special interest expressed by large dimensions, unconventional shapes and high material diversity. Especially with these unique shapes and connections, joint design is demanding and prone to mistakes. For integral joint specification, following some rough guidelines will result in a long-lasting and tight building envelope.
