Polymer Concrete Pits

Polycreteregistration mark Pits
Excellent insulation properties, high mechanical strengths, chemical resistance and zero water absorption, makes them ideal as electrical and communications enclosures.

Polycrete® Pits are made from polymer concrete and are available with a wide range of lids and access covers to Glass G (AS 3996). They are lighter and therefore less cumbersome than traditional concrete pits.


Plastic Pits

Polyethylene Pits
Recommended for light duty applications, they are robust, cost-effective and versatile. Plastic Pits are available with a wide range of lids and access covers to Class B (AS 3996).

Polyethylene moulded pits are lightweight, easy to cut and feature a ribbed construction for strength and durability.

SCEC approved pits

SCEC Approved Pits
The ACO PITLOK® and ACO COVERCOM® range has been fully tested and assessed by the national security service of Australia who appraises on behalf of SCEC. SCEC have subsequently endorsed the lids, plinths and pits for the ‘Protection of Classified Material’ to SL1 And SL2 respectively.

ACO PITLOK® comprises a system of compatible enclosure components to produce a SCEC SL1 rated enclosure. 2 product ranges are offered:

ACO COVERCOM® comprises a system of compatible enclosure components to produce a SCEC SL2 rated enclosure. It is the industry’s exclusive concrete pit range including tamper evident lids and precast reinforced concrete pits

Surface Ducting Systems

Polycreteregistration mark Ducting
Ducting are light and heavy duty surface ducting systems. Both are available in 100mm, 200mm and 300mm nominal widths and consist of one metre length modular channels that are assembled to produce continuous runs.

Lids are available in polymer concrete, steel and ductile iron to suit every application up to Class G (AS 3996).


EzyBrixx is a range of modular rigid plastic cable pits. The twin wall design features a unique interlocking wedge system which ensures component interlock and wall rigidity. In most applications concrete backfill is not required.
