Concrete Soakaway Rings

Manufactured with tongue and groove joints concrete manhole soakaway chamber rings can form a quick and effective method of storing and managing stormwater.

Soakaway units feature 75mm diameter holes providing a minimum area of exfiltration of 50,000mm², per metre of nominal diameter, per metre of depth.

Use a geotextile membrane around the outisde to prevent ingress of backfill material and top with a concrete ring cover slab, or 2-4 courses of regulation brickwork, and manhole cover to suit loading application. Chambers are considered confined spaces and access should be restricted.
