Rehabilitation & Relining

Reline or replace corroded existing manholes and chambers with corrosion-proof polymer concrete — stopping inflow & infiltration without full reconstruction.

Decades of corrosion leave existing manholes and chambers cracked, leaking and unsafe. Our polymer concrete rehabilitation installs a corrosion-proof structure inside or in place of the old one — restoring full structural integrity and stopping inflow & infiltration, often without full reconstruction.

• Corrosion-proof — resists H₂S, chemicals and saline ground
• 100% waterproof, non-porous structure
• 120 MPa compressive strength, no steel reinforcement
• Lightweight — faster, safer installation
• 100+ year service life, minimal maintenance
• Ashgal-approved quality
