Secant Pile & Shoring Wall Injections are specialized services used to reinforce underground structures, control water leakage, and improve the stability of retaining walls and excavation support systems. These walls are often used in deep excavations, basements, tunnels, and other civil engineering projects where soil and water pressures need to be controlled. Injection ensures a tight seal between piles or panels and enhances structural integrity.
Water leakage, voids, or gaps in secant piles or shoring walls can compromise safety and cause structural weakening. Injection techniques fill these voids with grout or chemical sealants, preventing water ingress and improving overall strength.
Our Services Include:
1. Inspection & Assessment
Surveying the wall or pile system to identify gaps, cracks, or leakage points.
2. Surface Preparation
Cleaning joints, gaps, or pile interfaces and installing injection ports for precise material placement.
3. Injection Methods
- Cementitious Grout Injection: Fills voids and strengthens the wall structure.
- Chemical/Polyurethane Injection: Seals water leakage and provides waterproofing.
- Compaction Grouting: Improves soil stability around piles if required.
4. Finishing & Quality Check
Ensuring proper sealing and structural integrity after injection, with tests to confirm effectiveness.
Common Applications:
- Secant pile walls for deep excavations
- Shoring walls in basement and underground construction
- Retaining walls for tunnels and bridges
- Water retention or cutoff walls
Benefits:
- Seals water leakage effectively
- Enhances structural stability and load-bearing capacity
- Prevents soil erosion and structural settlement
- Cost-effective alternative to reconstruction
- Extends life and safety of underground structures
This service ensures secure, water-tight, and structurally sound secant pile and shoring wall systems for safe and long-lasting construction.
