Geo Fabric Rolls

Geo fabric sits between the retained soil and the drainage aggregate behind your wall. Without it, fines migrate into the gravel and clog the drainage zone, and a blocked drain is the same as no drain at all.

It is the cheapest part of the drainage system and the one most often left off a materials list. It is also the part that decides whether the gravel and agi pipe you paid for are still working in five years.

Specifications

Both rolls work out to the same rate per square metre, so the width is a practical choice rather than a price one.

Which width

• 1m suits low walls, garden terraces and raised beds, where the fabric only has to line the back of the wall and turn over the top of the drainage zone.
• 2m suits taller walls and any job where you want to line the cut, run up the back of the excavation and still have enough left to fold over the aggregate. On a 1m high wall the fabric has to cover the full height of the drainage zone plus the return, so a 1m width leaves you nothing to overlap with.

How much to order

Work on the full length of the wall, plus an allowance for overlapping joins. Our wall calculator works it out alongside your gravel and agi pipe, and the drainage guide sets out quantities per lineal metre.
