ELECTRICALELECTRICAL PITS:

Electrical Pits can be manufactured from a variety of materials for a wide range of applications. They can be used for the underground connection of electrical cables, communication connections or fibre optics. Plastic for its light weight is an ideal choice. For its versitility and strength G.R.C. and for its load capacity and flexibility of manufacture Precast Concrete would be a great choice.

QualityIntensely vibrated precast concrete structures made in a factory controlled environment are generally superior compared to that attained under general site conditions. Concrete cover to steel reinforced to suit specification is achieved to a higher standard in a precast mould compared to in situ offerings.

TimingPrecast product can be delivered to site when site conditions and / or the contractor are ready. Being already cured, therefore finished product is capable of immediate use and acceptance of design load.

SafetyOpen excavations are dangerous and costly. With short installation times, personnel in deep excavations along with barricading and safety equipment / supervision are reduced to a minimum. Precast is an essential product for pedestrian access areas where same day job completion can be achieved.

DesignEach precast pit is individually manufactured to the client’s requirements. Penetrations and exact heights are incorporated directly from engineering plans to create a custom built pit where needed. A full range of access covers or gratings are offered to finish the project as specified.

EfficiencyQuick installation will result in reduced time spent on the job for both plant and labour. Excavations are open for less time, while immediate back-fill and clean up can be carried out as one continuous operation thus eliminating the on-going and costly return operations.

EconomicalPrecast pits are more economical when compared to in situ. With a stricter control of raw material quantities, labour and the ability to reuse factory mouldings, this makes the precast product a far cheaper item.

why use PRECAST CONCRETE ?

Glass Reinforced Concrete ( GRC ) is a generic name for a composite product constructed from a matrix of cement, fine aggregate and glass fibre. Methods of manufacture are the traditional vibration casting method similar to the precast concrete industry or the more common spraying through a special glass / slurry chopper gun. GRC combines the high strength of fibre glass with the rigidity of cement mortar to give a tough rigid material that has a strength to weight ratio superior to most other commonly used building products.

HistoryCooke Precast Concrete Pty. Ltd. commenced business in September 1996, with a staff combining together bringing many decades of knowledge and experience within the precast concrete, transport and specialists in the drainage industries.

OperationsThe Company manufactures from a factory at Edinburgh North, South Australia, with an extensive range of slip moulds for precast production in the drainage field, numerous moulds for sumps, side entry pits, inspection openings and cable pits. Cooke Precast Concrete can provide a large range of access cover products in addition to septic tanks, car park and domestic products. With our own large concrete batching facility we are able to produce consistent mixes as well as the special design batches like calcareous aggregate, fondag, coloured and high strength concrete. With the opening of our G.R.C. (Glass Reinforced Concrete) division in July 2000 our flexibility to supply all types of product is now complete.

CommercialCooke Precast are suppliers to Local Government, State and Federal Authorities and being a Quality Endorsed Company to AS/NZS ISO 9001:2008 we can comfortably perform to the required standards.

IndustrialWith our vast range we supply to Civil / Drainage and Electrical Contractors, Plumbers and Builders for projects ranging from housing development to new airports, or motels to take-away shops. We are proud manufacturers of a modular Pumping Station System (sizes up to 3200mm internal diameter) which are custom made and supplied throughout Australia and shipped to New Zealand.

DomesticFactory flexibility enables us to produce a full range of septic tank and ancillary products, also paving slabs, a range of walling sleepers and lawn edges for parks and gardens.

G.R.C. Drainage & ElectricalG.R.C. pit and linear drainage products are lightweight yet with the strength stronger than concrete. Cooke Precast produces a full range of easy to handle pits suited for both the electrical and drainage industry. Along with the linear drainage channel system (Rapid channel) being available ex stock with a choice of covers or gratings we can supply a lightweight alternative to complement our catalogue.

Pit InstallationSection Detail

Ground PreparationExcavate the hole to suit the pit, put a bag mix concrete pad fo the pit to sit on, in order to create an even solid base.

1 Pit PlacementSet the pit in place, and connect the appropriate pipe work to the pit.Note: with a grated pit the grate sits inside the pit. A solid top cast iron cover sits over the pit.

2 Back FillBack fill the hole with stabilised crushed rock or concrete depending on the load classifaction.

3 Protective EdgeNote: all pits require a concrete surround at the top edge of the pit for protection against vehicle impact.
