Product features & Benefits
Concrete infill recessed covers
Recessed covers are designed for filling with concrete as specified in BS EN 124 – C45- 45 N/mm2 for a test cube of 150 mm, or a 40N/mm2 for a test cylinder 150mm diameter x 300 mm high, using a 10 mm coarse aggregate.
Anti-slip surface covers
Concrete infill covers provide a non-slip surface similar to the surrounding areas. Solid top covers incorporate a raised lozenge pattern on the surface.
Materials
The components of Elkington covers are manufactured from the following materials: Ductile iron components to BS EN 1563:1997 Structural steel sections (removable beams) to BS 4-1:2005
fine tolerances
The seating faces of Elkington covers and frames are machined to ensure metal-to-metal contact within 0.25mm tolerance.
non-rocking
Correctly installed, Elkington covers will be non-rocking under traffic and sealed against ingress of road dirt and other detritus.
Watertight
A film of graphite grease between the contact faces of Elkington units provides a gas and airtight seal, and a watertight joint under normal rainwater conditions.
Pressure-tight
Standard single units with locking screws and holding-down bolts are available to withstand upward pressure. Consult our technical department for details.
Easy removal/replacement
The machined underside seating face of Elkington covers allows the sliding out of covers for easy removal or replacement.
operator control
Jack screw operating keys locate positively and securely into Elkington covers and are a necessary tool if the inherent cover seal is to be broken effectively and to allow operator maximum control during operation.
Secure and vandal resistant
Covers are designed to prevent tampering and unauthorised removal. Elkington covers cannot be removed without the correct lifting key, so unauthorised removal is virtually impossible. Locking bolts can be fitted to Elkington cover keyways as an additional security feature.
vibration resistant
To prevent movement of covers in high density traffic conditions, we recommend the use of a factory-fitted vibration-resistant locking system. Can be fitted to recessed covers only.
Closed keyways
Elkington cover keyways are closed and fitted with plastic plugs to prevent them from blocking up.
frame bars
Elkington 140 mm deep supporting frames incorporate an ‘I’ beam design profile to provide a robust and rigid frame that will withstand the specified loads, without any concrete infill or backfill.
rigidity
The robust and rigid design of Elkington D400, E600 and F900 frames, combined with close manufacturing tolerances, provides a monolithic structure that will withstand the dynamic effects of traffic movement and impact.

Secure support
The clear opening width between supporting frames are at least 10 mm greater than the pit/chamber design to allow for minor deviations in pit construction dimensions.
Beam wallbox
Supporting beams in Elkington Multispan units are easily removed with appropriate lifting equipment for access to the total chamber area. Beam wallboxes do not project into the chamber opening.
finishes
Units are coated with a black bituminous solution that acts as a temporary protection during transit, Removable supporting steelwork is galvanised to BS EN ISO 1461:2009.
installation
Consignments of Elkington units are accompanied by comprehensive installation instructions.
levelling bolts
All side frame bars and wallboxes are fitted with bolts to assist in the levelling of the unit during installation.
