Direct injection is the most proven and reliable method for sealing leaking cracks and joints in concrete. Port holes are drilled into the concrete of the affected structure which are then pumped with resins under pressure to ensure they fill the entire space of the crack/joint. This cures to form a solid resin, flexible gel, or high density foam that provides a long lasting seal.
Benefits of Direct Injection
- The huge variety of resins available allows all cracks, from hairline to fissure, to be sealed using the system.
- Cracks can be sealed whether they are actively leaking, damp, or dry.
- Many resins remain flexible so will allow for some movement whilst maintaining their seal.
- Cure times and the extent of resin travel can be adjusted and controlled on site.
- Direct injection helps to prevent corrosion and concrete spalling by encapsulating the reinforcement steel.
- Compatible with concrete repair mortars and a range of paints and coatings. Visit High Impact Coatings for more information on our range of paints and coatings.
