Giant roll of the special porous pipe

The tube is carefully laid along the whole length of the drainage ditch

The tube is then wraped in the Geo-Textile to filter any soil that might make it through the gravel to the tube. The tube is then covered in the filtration gravel.

The trench is then filled with the filtration gravel and packed down. The Geo-Textile material is folded over the top so that when the soil is replaced no soil passes with the rainwater into the gravel. The soil is then replaced and the grass relayed.
