Asked Questions

What drain should I install?

This depends on a lot of factors such as desired aesthetic, what load class you need & where is it being installed. Check how much water the area will receive, has it got a slope? Is it near your pool? Do you live near saltwater?

What is nominal wheel loading?

The nominal wheel loading refers to the weight of 1 wheel of the vehicle.

For example, if you estimate the heaviest vehicle that will be driving over the drain weighs 2215kg. The nominal wheel loading is 553.7 kg (2215 ÷ 4 = 553.75). Therefore you will require a Class B rated grate (Class B nominal wheel loading is 2670kg).

What is polypropylene?

Polypropylene is a material with excellent mechanical, physical and chemical properties.

Some of the most significant properties of polypropylene are:

Chemical Resistance: Diluted bases and acids don’t react readily with polypropylene

Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of deflection (like all materials), but it will also experience plastic deformation early on in the deformation process, so it is generally considered a “tough” material. Toughness is an engineering term which is defined as a material’s ability to deform (plastically, not elastically) without breaking..

Fatigue Resistance: Polypropylene retains its shape after a lot of torsion, bending, and/or flexing.

Insulation: polypropylene has a very high resistance to electricity.

What lengths do the channels come in?

Most SABdrain channels are sold in 1M lengths to be joined together. They are easily cut, allowing installers to achieve exactly how many metres they need.

Sizes above 200mm x 300mm are sold in 500mm pieces
