Injection is a specialised process where materials are pumped into cracks, joints, voids, or behind structures to repair, seal, or strengthen concrete and masnonry without demolition. At PCR, we select and apply the correct injection method based on the structure’s condition, water pressure, crack behaviour, and long-term needs.
✅ Our Injection Capabilities Include:
1. Epoxy Injection
For structural cracks in beams, slabs, and columns
- Rigid bonding
- High strength
- Used in seismic and load-critical repairs
2. Polyurethane Injection
For active water leaks and moving cracks
- Expands to seal
- Flexible
- Ideal for basements, retaining walls, and lift pits
- Systems: Köster 2IN1 (both PU + re-injectable), Sika Injection-201
3. Acrylic Gel Curtain Injection
For inaccessible areas (e.g. lift shafts, external walls)
- Low-viscosity resin gels in surrounding soil
- Forms curtain membrane behind concrete
- Ideal where external waterproofing isn't possible
4. Joint Injection
For construction/cold joints that are leaking or at risk
- Stops lateral water movement
🛠 Our Process:
- Leak tracing and structural assessment
- Drilling and port installation
- Injection via manual or controlled pump system
- Finishing and sealing of injection points
- Optional overcoating or surface waterproofing integration
