Drivetex Ground Stabilisation
A heavy duty, non-woven geotextile fabric providing the best performance in ground stabilisation, filtration and drainage. Drivetex is a professional driveway fabric, to be used beneath MOT Type 1 or 3 aggregate or hardcore in sub-base layers. This prevents sinking and rutting caused by settlement of aggregates into the soil beneath (sub-grade) – a process known as ‘pumping’.
This high quality product does not lose strength when used below ground, making it the ‘number 1’ choice for driveways, roads and other areas subject to vehicular traffic. Drivetex can also be used for the construction of land (French) drains, for wrapping soakaway crates and for use beneath permeable paving and other SuDS compliant installations.
Our standard sized roll is 2.25m x 25 metres, other sized rolls can be ordered, each order would be priced according to quantity and carriage costs.
(for use as a ground stabilisation membrane)
1. Excavate soil (sub-grade) to the required depth (allowing for sufficient depth of sub-base, base course layer and the surface finish e.g. block paviours, tarmac etc, including any base layer required for these – depths of each layer will vary depending on the intended use e.g. pedestrian/vehicle use, light/heavy use).
2. Lay DRIVETEX fabric out and ensure joints are overlapped by a minimum of 300mm (overlaps should be kept to a minimum). For some applications the specification may require DRIVETEX to be jointed using other methods, e.g. stitching, gluing etc.
3. Secure using EXTRAFIX fixing pegs.
4. Lay sub-base layer over the fabric and compact using a compacting plate or roller.
5. Following installation of the sub-base, base layers (e.g. base coat tarmac) for the surface finish can be laid.
(for use as a drainage membrane)
1. Excavate a trench to receive the land drain, to a suitable depth and width.
2. Line the base and sides of the trench with DRIVETEX fabric, cutting it to a suitable length and width where required. Overlaps should be kept to a minimum, but where necessary they should be a minimum of 300mm. Leave enough DRIVETEX fabric protruding beyond the top of the trench on both sides to cover (with an overlap) the shingle/gravel before backfilling the top of the trench.
3. Lay a bed of 10mm pea shingle (or similar clean, non-limestone gravel) in the base of the trench on top of the DRIVETEX fabric.
4. Lay the perforated pipe on top of the shingle and fill round with more shingle/gravel, making sure there is at least 75mm surrounding the pipe.
5. Cover the top of the shingle/gravel with the remaining DRIVETEX fabric (see point 2).
6. Backfill the rest of the trench with soil before installing the surface finish e.g. turf.
