What are concrete manhole rings?

Concrete manhole rings are manufactured in accordance with BSEN1917, BSEN5911-3 and BSEN5911-4. Manhole rings that are signed off to meet these standards are given the Kitemark stamp so they’re easy to identify. Concrete manhole rings are used to manufacture manhole access to sewer systems and drainage systems. Whether you use concrete rings or not depends on the depth and the requirements of the inspection system.

Pre-cast concrete manhole rings are used for when construction goes deeper than 1m. They’re the most commonly used product to create circular manholes, with minimum diameters depending on the depth of the system. The minimum diameter for depths up to 1.5m is 1050mm and the minimum diameter for anything deeper is 1200mm.

Some concrete manhole rings come with step-irons. These are yellow cast iron steps which allows workmen to safely climb up and down the manhole with secure foot and hand holds. If a concrete manhole ring without step-irons is purchased, then they can be added on separately using mortar.

What is a concrete cover slab and why might I need one?

Concrete cover slabs, also known as biscuits, reducing slabs and lids, are used to finish a stack of manhole rings on the main shaft. They create a single access opening in the most common 600mm x 600mm opening dimensions. This allows maintenance with tools and cameras and it also reduces the size of the opening should the manhole cover itself be tampered with.

Giving concrete cover slabs the alternative name ‘reducing slabs’, cover slabs can take an 1800mm diameter opening down to just 600mm x 600mm which greatly reduces risk to the public. It reduces the risk of adults, children and pets falling in should the manhole cover itself be removed.

Serving as a base for the manhole cover too, concrete cover slabs offer a reliable and heavy duty platform to create an all-round safer construction.

What are step-irons?

Step-irons are either pre-built or added on to concrete manhole rings to create steps to allow access safely into the system. Yellow in colour so they’re very visible, step-irons are typically made from stainless steel or cast iron which is then coated in plastic for strength and grip. Choosing a stepped or non-stepped concrete manhole ring is dependent on the requirements on the manhole.

What are concrete chamber sections?

Concrete chamber sections mostly refer to square or rectangular chamber sections. These types of products are also available in ring shapes, known as concrete manhole rings. Concrete chamber sections are manufactured from pre-cast concrete which has been factory-controlled to ensure it’s of high quality. Concrete chamber sections are also known as HICs (House Inspection Chambers).

Pre-cast house inspection chambers are available at Drainage Superstore manufactured by brands such as Marshalls CPM and Advanced. They are manufactured to meet British Standards in a variety of dimensions.
