ACO Water Management has expanded its most popular range of monocast drainage channels to deliver greater hydraulic capacity and cut installation costs.

MonoDrain® is a monolithic general-purpose channel drainage system for surface water conveyance and is suitable for the core application of channels drainage in car parks, town centres and commercial developments.

The new MonoDrain PD150D is an expansion to the existing PD100D channel. Made from the same high strength Vienite® polymer concrete, the PD150D has an increased bore width of 150mm, allowing for a greater hydraulic capacity across a larger surface area.

It requires fewer drainage runs to manage the water, making the PD150D a solution for larger projects, with the assurances of BS EN 1433:2002 certification and a load class of D 400 for general vehicle parking areas.

The channels are available in one metre lengths, improving installation speeds, while each unit requires just 100mm of concrete haunching.

This allows for up to 41% less concrete use compared to other monocast channels, and up to 56% versed grated channel equivalents.

Specifying the MonoDrain® system could equate to significant savings over £5.07 per metre*.

The expanded one-piece range includes 10mm Heelguard™ inlets.

They are available in three colours, black, grey and natural, the channels provide engineers and architects versatility for their designs, making it possible to co-ordinate with asphalt, concrete or natural paving.

The range has an improved access unit, incorporating a thermoset composite frame and lid to provide protection from oxidation.

The self-locking function allows easy access, while the channel can be maintained in the same way as a traditional grated system through pressure jetting.
