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

Key Features & Benefits
Precast cover slabs offer significant advantages over in-situ construction:
High compressive strength
Factory-controlled quality
Reduced on-site labour
Faster installation
Long service life
Dimensional precision
Suitable for trafficked areas
Full specifications
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.
Compliance & Technical Support
Elite Precast cover slabs are manufactured in accordance with relevant UK standards and industry best practices.
We support:
Civil engineer specifications
Highway authority approvals
Infrastructure design requirements
Structural assessments
Project documentation processes
Technical drawings and dimensional information are available upon request — call 01952 588885 (6.00am – 4.30pm, Monday to Friday) and talk to the team.
Bespoke Options
Where standard sizes do not meet your project requirements, we offer bespoke manufacturing, including:
Custom diameters
Non-standard accesses
Multiple access openings
Lifting point configuration
Reinforcement modifications
Load classification requirements

Frequently Asked Questions
What is a precast concrete cover slab?
A precast concrete cover slab is a structural concrete unit used to cover manholes or drainage chambers while supporting access covers and distributing surface loads.
What is the difference between standard and bespoke diameter cover slabs?
Standard cover slabs are typically used for conventional manholes and drainage chambers, with a 600 x 600, 675 x 675 or 1200 x 675 opening. Bespoke or special cover slabs have project specific openings and loadings.
Are your cover slabs suitable for highways?
Yes. Our slabs are manufactured from high-strength precast concrete and can be designed to meet heavy traffic load classifications when specified correctly.
Do you manufacture bespoke cover slabs?
Yes. Elite Precast can manufacture custom-sized cover slabs with tailored apertures, reinforcement and load capacities to suit project requirements.
Are your cover slabs compliant with UK standards?
Yes. Our products are manufactured in accordance with relevant British Standards and drainage industry requirements.
