Injection is a procedure of pumping cement-based, polyurethane-based, epoxy-based or acrylate-based material into damaged or cracked structures to securely seal leaks, repair compromised structures and make them watertight again for the long term.
Successful Waterproofing with Sika Injection Systems
There are three primary success factors involved in ensuring the effectiveness and durability of injection projects. It is essential that the right combination of injection materials, injection equipment and injection method are selected. Together, this is what Sika’s extensive technical and practical experience provides:
Injection Material
The selection of the right injection material and the right specific injection product for the defined project requirements is the first key factor for success. The material’s viscosity, flexibility and behavior in contact with water are especially important - all which can significantly influence the effectiveness of the injection.
Injection Equipment
The second key success factor is having appropriate equipment for the selected injection material - for correct material preparation, mixing and delivery. This includes: the initial dosage and mixing, delivery from a suitable pump, to use of the right packers/ ports/ connectors.
Injection Method / Application
Thirdly, the correct injection method and application techniques must be followed by trained, skilled and experienced contractors, to ensure the success and provide complete, permanent leak-sealing solutions.
