Pressure injections
Eliminating leaks in existing concrete structures by injecting resin under pressure.
How it works
Pressure injections
Pressure injection is the most effective method of sealing and eliminating leaks in concrete structures. It involves drilling holes, installing so-called packers in them and injecting resin under pressure.
Injection seals not only leaks visible to the naked eye but also fills fine cracks and pores. Sealing injections eliminate leaks in cracks, construction joints and expansion joints.
What is injection. Injection is a process in which suitably selected sealing substances are forced under pressure through a pattern of holes drilled in the structure. Pressure injection is a non-invasive method that eliminates the causes of leaks and damp.
Types of resin
- epoxy resins, whose cured strength exceeds that of ordinary concrete, intended for joints transmitting considerable forces,
- polyurethane resins, used mainly where watertightness must be ensured.
