Product description +
A black underground riser seal base is designed to create a secure and watertight connection between the inspection chamber base and the riser section. It ensures a tight seal that helps prevent water ingress and stops leaks within the underground drainage system.
Manufactured from durable black PVC, it is built for long-term underground use and integrates smoothly with standard inspection chambers, risers, and covers. The secure fit supports structural stability while maintaining reliable system performance and easy access for future maintenance.
