Reducing Slabs

• Add to project

Concrete reducing slabs are used in the main shaft construction of manhole chambers to suit up to and including 4000mm chamber sections. They are generally manufactured with a 900mm, 1050mm or 1200mm circular reducing section and are used to reduce the access point opening size into the chamber section

Benefits of the system include:

• 900mm, 1050mm or 1200mm reducing section.
• Eccentric access positioning.
• Fits flush to the chamber ring.
