Pit InstallationSection Detail

Ground PreparationExcavate the hole to suit the pit, put a bag mix concrete pad for 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.

Rapid Channel Installation DetailSteps to Install Rapid Channel

Ground PreparationExcavate the trench for the drain to the appropriate level, noting that you need to allow at least 100mm of base concrete under the channel for support. When complete line the channels up along the trench to ensure all the pieces are there.

1 Concrete BasePour a base of 30 mpa concrete into the trench and level out, then place the channels onto the stiff mix of concrete. Using a rubber hammer you may have to tap down the units until you get the required level. Always start laying the drains from the outlet point back as this makes it easier to attach the socket joints together. To achieve a straight line use either a laser light or string line on the top surface.

2 Final PourAfter the base has set, finish off the drain by placing concrete on either side of the channel to the finished level.

Reinforcing around the base of the drain is not required in most cases. However due to different ground conditions and applications this is not always the case. You may need to seek engineering advice.

3 Top EdgeRemember the concrete should be 3 to 4mm above the top edge of the channel. This will allow water easy access to the drain and avoid traffic impact.

Our G.R.C. Products division has the flexibility to manufacture special or custom products to your requirements.

At Cooke Precast we have a steel engineering facility that can manufacture moulds and patterns to meet the exacting tolerances needed for a quality product.

Together with our precast concrete plant and working together with our customers we can offer a complete package from a design idea through to a quality endorsed product.

A good example of this is the two products shown on this page. Both are sold using G.R.C. and Precast Concrete with Steel or Alloy Covers all of which constructed at our Elizabeth plant in South Australia.

At Cooke Precast we provide the construction industry with better products by improved design.
