Cover slab
Bespoke cover slabs designed around your project requirements
Not every network access infrastructure project is suited to an off-the-shelf cover solution. For these applications, Cubis Systems can offer bespoke concrete cover slabs.
Cover slabs sit outside our core access cover range as a tailored option for covering larger chambers and meeting more demanding site requirements.
Each slab is designed around the project in question. D400 and F900 options are available to suit the required opening size, loading class, and access arrangement.
Cover slabs complement our D400 composite and ductile iron cover ranges, extending the options available when a more tailored solution is required for heavy-duty access. Get in touch to discuss your requirements.
Key product highlights
Bespoke to each specification
Cover slabs can be manufactured to suit virtually any chamber size and opening arrangement. Ideal for applications where standard cover setups don't suit.
Heavy-duty load capacity
Available for D400 and F900 applications, concrete cover slabs are designed for sites with high traffic volumes, heavy vehicles or intensive point loads.
Large clear openings
Bespoke cover slabs help safely span sizeable, non-conventional openings while still meeting the project’s loading requirement.
Optimised accessibility
Apertures can be positioned directly above below-ground assets. So, maintenance teams can access cables and equipment without removing the full slab.
Enhanced security options
Padlockable sub-security covers can be bolted into the concrete slab to help prevent unauthorised access to critical network infrastructure.
Flexible cover arrangements
Once the slab is installed atop the chamber, standard covers can then be installed above the slab or recessed into it - allowing easy future access.
Full system solution
Cover slabs integrate with our STAKKAbox™ access chamber systems and cover ranges, giving a fully coordinated solution for larger infrastructure projects.
Tailored technical support
From chamber dimensions and asset locations to loading requirements and access needs, we work with project teams to develop a solution that fits.
How it works
Concrete cover slabs are designed around the individual requirements of your project. Our team reviews the chamber size, required loading class, site conditions, access points and asset locations before developing a bespoke slab arrangement. This can include integrated apertures, recessed ductile iron covers and sub-security covers where required. The finished slab is manufactured to provide a secure, durable cover for the chamber below, helping protect critical assets while maintaining practical access for inspection and maintenance.
