Adding multiple levels of parking to alleviate congestion, will see plenty of room for rugby supporters in future.

The water table needed to be lowered for the basement layer where bidim was used in drainage trenches and as a separation layer between the in situ and aggregate at the base of the surface bed.

The bidim used in this project was produced using
214 000 recycled cooldrink bottles.

Unsuitable in situ material at the site of this access road – due to a high water table – was excavated and infilled with dump rock. The high strength of bidim A8 and its filtration properties, ensured adequate adequate movement of underground water away from site.

The bidim in this project used the equivalent of
12 132 recycled cooldrink bottles.

A cutting almost always creates a problem with water that seeps into the layer works of the road. A cut-off trench was dug around the foot of the hill to accommodate for a sub-soil drainage system consisting of bidim A4, 110mm drainage pipes and 19mm stone. This drainage system prevents water running into the layer works of the road that can lead to deformation of the road.

The bidim used in this project was produced using
49 232 recycled cooldrink bottles.

The bidim in this project used the equivalent of
3 978 recycled cooldrink bottles.

N4 Kaapmuiden, 2014

This section of road constructed in a valley, has been vulnerable to ground water and consequent damage. Precast concrete cantilever walls were used to retain the imported material for the widening of the road. bidim was installed as a filter fabric over the entire wall area.

N1 Pienaarsrivier, 2014

The median of the highway lies well below the surface level of the fast lanes in both directions and large volumes of water build up in the median and filter into the layer works on both sides, degrading the base which eventually causes cracking and rutting.

Installed subsoil drains using bidim A4 in the median, drains the water in this area to stop the ingress of water and protect the layer works. The water collected by the subsoil drain is tapped off into storm water drains in the median.

The bidim in this project used the equivalent of
over 528 000 recycled cooldrink bottles.
