What? We needed to create a driveway at our home. The ground was originally a lawn and we were aware that making a hard surface drive would increase runoff into the surface water drainage system.
Where? End terrace, Heptonstall.
When? Spring 2017.
Design:The ground was cleared and approximately 100mm of course rubble was laid an compacted. This was topped with type 1 mot and coarse sand to create a smooth level surface.
Recycled plastic geogrids were set on this surface on top of a permeable membrane. It was then filled with washed pea gravel.
Benefits/Constraints: The adding of a drive in a village with restricted parking is of huge benefit to the community as well as ourselves. Although the cost is substantial it’s quite easy to do, so labour costs can be minimised. The geogrids retain most of the pea gravel, although some escapes. Over time the pea gravel settles so the geogrids start to show, particularly on the wheel tracks, this can be overcome by redistribution of the gravel. Weeds do still grow in the pea gravel so these need dealing with, but pull up quite easily.
Further Opportunities:The pea gravel was chosen for cheapness, other more decorative materials could be used if desired.
Who? Mitchell Excavations did the groundwork, P&J dropped the kerb. The rest was done by myself.
Funding: The initial groundwork cost £1200 Materials about £1000 Labour was free as I did it but about a 7 man days. We required a dropped kerb, this needs permission from the local authority £105, plus £900 contractor cost.
Building / Implementation: We required a dropped kerb, this needs permission from the local authority.
