Challenges

Precast sewer lids and access covers are exposed to groundwater, sewage gases, and continuous moisture. Inadequate sealing materials can harden, crack, or lose compression over time, leading to water ingress, odour leakage, and increased maintenance.

Solution

Forech supplied a solution manufactured from **EPDM Rubber Sheet**, specifically selected to meet the mechanical, environmental, and operational requirements of the application.

• Forech EPDM Rubber Sheet with excellent resistance to water, sewage gases, and weathering.
• High elasticity and compression recovery ensuring long-term sealing performance.
• Stable material properties under continuous moisture exposure.
• Custom-cut EPDM rubber sheet profiles to suit precast concrete interfaces.

Outcome

• Achieved reliable watertight sealing of precast sewer lids
• Reduced groundwater ingress and odour escape
• Lower maintenance and inspection frequency
• Extended service life of underground precast infrastructure

Conclusion

By using Forech EPDM Rubber Sheet, the project achieved durable and long-term sealing performance. This case study demonstrates Forech’s capability in supplying engineered rubber sheet solutions for critical underground infrastructure applications.
