Herewith more photo’s showing the installation of the mattress apron below the gabion structure on a layer of geotextile. On-site training for installation is taking place with our gabion toolkits showing the correct rock size and quality to be used and the correct lacing together of adjoining mattress units, using the Binding wire supplied with the materials. These units are laced together using the preferred lacing technique along all common joins so that the structure become one integrated monolithic wall.

To counter all future loads imposed on it in the long term. Base baskets and mattresses are all Class A Galvanised and PVC coated to prevent long term corrosion of steel wire along the water’s edge. Higher basket layers do not require this due to infrequent flooding to this level. Already they are achieving 30m3/day using 30 people on site, indicating production rates of 1man/m3/day, for the erection of the basket, including , bracing, lacing and packing.

The structure is proceeding well, and visual evidence of progress is now very evident. We are racing against the imminent river rise when the rain comes.

Herewith more photo’s showing current progress on the riverwall in Upington. All seems to be going well and with speed. The owner is also involved with monitoring progress on site and is impressed with progress.

It is continuing as before with rock being supplied in greater amounts now, there was a time when the rock was a little oversized, as a maximum 250mm size is allowed, this has now been corrected.

More photo’s now taken as the project continues, we have received many more gabion inquiries from the Northern Cape area due to this project. As can be seen now they are achieving more than 30m3 per day, as they place and prepare a whole section of baskets first, before placing the rock into the baskets and tying them down the following day.
