Stacked 1200 cover slabs marked 600 x 600 in a storage yard

Concrete manhole cover slabs

Elite Precast manufactures high-performance precast concrete cover slabs for drainage chambers, manholes and large diameter infrastructure applications across the UK.

Designed for strength, dimensional accuracy and long-term durability, our cover slabs provide secure structural closure for both standard and large diameter chambers in highway, commercial and infrastructure projects.

Manufactured in a controlled factory environment, our cover slabs deliver consistent quality, compliance and installation efficiency.

What are Concrete manhole cover slabs?

We supply both standard manhole cover slabs and special cover slabs, ensuring full coverage across your drainage and infrastructure requirements. Seating rings/adjusting units can be delivered at the same time as the cover slab, to reduce haulage costs, compliance and paperwork.

Used in drainage systems and inspection chambers, our manhole cover slabs:

  • Provide structural support for access covers and frames

  • Distribute traffic loads effectively

  • Maintain chamber stability

  • Ensure compliance with UK drainage standards

Engineered for heavy-duty loading conditions, our large diameter and special cover slabs offer:

  • Increased structural capacity

  • Enhanced reinforcement options

  • Bespoke sizing capability

  • Compatibility with large chamber systems

Suitable for residential, commercial and adoptable drainage schemes, as well as:

  • Major infrastructure projects

  • Deep drainage chambers

  • Utility shafts

  • Stormwater attenuation systems

  • Highway and civils applications

Installation Overview

As well as supporting design flexibility, installing special access cover slabs reduces the environmental impact of your project on the local environment, as off-site manufacturing minimises air pollution, vehicle movements and wastage on site.

It also supports Health and Safety on-site, as it reduces in-situ installations.

Special Access Cover Slabs are delivered to suit site ready for immediate installation on agreed dates that support site programmes, rather than holding up site schedule times.
