“Two men laid 70lm of DuraKerb in 2:15 hrs (first time using DuraKerb). The productivity with DuraKerb was found to be 3/4 times greater than with concrete kerbs and there was a reduction in traffic management costs.” Essex County Council

DuraKerb: Laying & Cutting Method

DuraKerb is installed in the traditional manner & no additional training is required.

Dry and Wet Bed Laying Method

A dry mixed concrete, or ready mixed concrete, the latter having a slump of 25mm to 35mm (ST1 / BS 8500), is required. The string line is to be set up on pins and set to correct level. The concrete is to be placed along the intended line behind the string. The concrete should then be spread and struck level with a shovel, leaving no high or low points. Check that the minimum specified thickness of concrete at least is under the struck concrete surface.

The DuraKerb is then to be taken from the pallet or truck and placed on the concrete bed, laying from the left offering it to the string line. This is done from the verge/footway side, holding the DuraKerb with both hands. It is then to be adjusted into position using a small rubber hand maul. With a hand on the top, the surface is then to be tapped into position until flush with the string line.

The second unit is then introduced by offering it to the string line at the end of the first DuraKerb. Ensure that the male alignment spigot on the end face of laid kerb is located snugly in the female slot of the kerb being laid. The DuraKerb has a 2.5mm lug integrated into the side face to reduce contact between kerbs, which in turn facilitates the reduction of spalled kerbs during installation. The laying process is then repeated, checking that the first DuraKerb has not been disturbed, adjusting as necessary with the rubber maul. Successive DuraKerb units can then be added to the line.

On completion of the kerb line, backing concrete is to be run out from the shute behind the DuraKerb, covering the lateral flange, keying the DuraKerb to the haunching and race. The kerb layer then faces off the front of the kerb race, trimming flush to the front flange of the DuraKerb. The rest of the haunching should then be trowelled into shape and then the line of DuraKerb should be checked again for accuracy.

 

Single Installation and Cutting Method

The male fitting can easily be removed if required for single installation, by cutting. If lengths shorter than standard kerbs are required then measure the required length and cut accordingly.

DuraKerb advocate the use of hand tools when cutting to eliminate respiratory concerns and lifting tongs by installers in an upright position, in order to minimise the risk of posture strain and hand/wrist injuries.
