Pre-sloped MultiDrain M100D units are available where required, typically in areas subject to chemical leaks.

However, for most standard applications, level channels laid flat will usually be sufficient.

Yes. Level invert channels include a vertical knockout for pipe connection, or you can use the multifunctional end cap for a horizontal pipe connection.* When a sump unit is specified, multiple outlet options are available to suit different depths.

*Please note: MultiDrain shallow channel sections require a dedicated outlet unit for vertical connections. A horizontal pipe connection is not available for shallow units.

Yes. Pre-sloped MultiDrain channels are designed with a 5 mm fall per metre, up to a maximum channel run of 20 m. If the ground gradient is shallower than this, the system can be installed to discharge at the ‘high’ end.

The channel should be installed so that its top edge aligns with the top of the sump unit. Sump units are supplied with a cut-out section that can be created after the channel is installed, allowing the two components to be connected correctly.

A T connection can be formed using the MD 0.5m length channel sections, which include cut-out sections on both sides to allow a channel of equal depth to be connected at 90°. For larger sites or higher capacity requirements, a universal gully can also be used.

Yes. MultiDrain channels can be cut to length and mitred to achieve changes in direction. When doing so, ensure no sharp edges are left exposed and treat any cut metal to minimise the risk of corrosion. It is also important to cut both the grate and channel so that the grate’s anti-shunt feature remains aligned with the channel, and to ensure the Drainlock mechanism is retained.

No. ACO does not approve or recommend contractors, as we are not directly involved in the installation of the channels. We advise that any contractor is carefully vetted to ensure they have the relevant experience and are suitable for the specific works required.
