Crack Repair Using Pressure Injection
The repair of the concrete structures is suitably accomplished using pressure injection of the damaged areas with a liquid polymer, which hardens with time. Other applications, such as those involving very thick-walled structures (e.g. tank repair) or where a high volume of water flow must first be stopped may be better suited for high-pressure injection.
Types of injection
force injection
Description
Filling the gap or crack with epoxy resin that connects the structural elements in a way that allows the transfer of stresses between them (thanks to which they work as one element).
Recommended uses
Concrete, cement or PCC substrates.
sealing injection
Description
Forcing into the scratch or the cross-section of the element flexible polyurethane resins or gels that seal the partition.
Recommended uses
Ceilings of underground car parks, foundation slabs, external walls.
