Leaking concrete structures below ground such as basements and civil engineering structures, can have a greatly reduced service life due to steel corrosion and concrete damage, in addition to any reduced functionality and use. In order to avoid the expensive costs of repairs to the structure, or to water damaged interior finishing’s, furnishings or other goods, plus the costs of any operational downtime, these leaks can often be securely sealed and waterproofed by injection.
Sika provides an extensive range of injection systems for all types of leak sealing applications in concrete, masonry and natural stone structures. These can be used at any time, including during the initial construction works, or later to extend the service life during any subsequent refurbishment, according to the specific project’s requirements. Sika injection systems can not only close, flexibly bridge, seal and make leaking structures watertight for the long term, some can also be used to increase or restore structural integrity and load bearing capacity, thereby providing complete and durable maintenance solutions.
Sika's high performance injection materials are also fully compatible with Sika’s complete Engineered Waterproofing range and they can be used for the repair and sealing of cracks, voids, joints,hoses and compartment systems in many different structures. As a prerequisite, all of Sika’s injection products are also fully tested and conform to all of the relevant global standards.
