How to install this product:
In the product guide, the instructions to install the product are as follows:
- Dig the trench 318mm wide (218mm wide if against a structure) by 200mm deep for the channel (400mm deep for sump). Mark the finishing height with a fixed line 3mm below the final surface. Lay 100mm (min.) bed of concrete.
- Knock out the pre-formed outlet from the inside (marked with hammer symbol) or fit the sump or outlet endcap. Position sump or outlet channel on a concrete bed, fit PVC-U union/trap to drainage pipework.
- Lay channels starting from outlet/sump, ensuring joints connect by lowering units horizontally. Fit endcap to end channel. For fully watertight joints, use a suitable sealant.
- With gratings fitted, haunch around channels/sumps with concrete (suitable fill material). The final surface is to be 3mm above the grating. Bricks/paviours should be laid in mortar for lateral stability.
ACO drainage systems can be used for a variety of commercial or domestic purposes, or on industrial properties or environments.
