Kerb Inlets

Kerb Inlets

Precast concrete Kerb Inlets are supplied to various municipal specifications, i.e. Tshwane Type and Johannesburg Type. They come in configurations of precast concrete channel (600mm lengths), steel frame and concrete slabs, and can be supplied in any length of 600mm sections. There are two applications, one being drop outlet and the other, end outlet.

Correct side of road

To ascertain what hand (direction of water) the kerb inlet (KI) is, do as follows: Stand in the middle of the road, looking at the KI/Catchpit. Whichever direction the water is coming from, i.e. from your left side, then the KI is classified as a Left Hand.

 

Any drainage system is as good as the kerb inlet. There are essentially five requirements to this vital structure:

 

  • Hydraulic efficiency – this is the most important aspect of a kerb inlet and therefore requires the greatest attention including the need to remain unblocked at all times
  • Structural sturdiness – the proximity of this structure to the road requires that it is capable of withstanding any static or dynamic loads to which it may be subjected
  • Safety – any deviation of the kerb lines, or the gutter creates a potential hazard for passing traffic or pedestrians
  • Maintenance – without suitable access for periodic cleaning, this will soon become clogged and of no use whatsoever
  • Economies of cost – the kerb inlet represents approximately 15% of the value of a storm water reticulation and should, therefore, be cost effective

 

Our range of kerb inlets are very effective.
