Hello again.
I finally got round to starting to lay a shingle drive. I am aiming to lay 100mm of compacted scalpings then 40 - 50 mm of shingle on top. The scalpings will be compacted, i already did a post on this and was pointed at a useful website - i am borrowing a mechanical compactor.
The driveway will replace an old front lawn.
I wanted to use a geotextile under the scalpings to stop the sub base blending in to the surface layer. I should say now, that after excavating away the depth of soil for the driveway i have exposed a layer of clay.
After all the rain today, it now looks like a pond. There is no where for the water to go as i effectivley have a 150mm deep pit. (Hemmed in by kerbstones on 3 sides).
I got very confused in Wickes when buying the Geotextile. Drainage is a major concern (the water table is so high at the moment, my back grass is litrally under water today, also being on clay).
I bought 2 different rolls of stuff, planning to take the one i do not use back for refund.
First roll is called "Driveway Fabric" it is a woven roll. It says "Prevents water from penetrating the substrate" and "prevents puddles and pools from forming on the driveway". Both of these statements sound totally contradictory to me. Is is permiable or not? This is the stuff that i would rather use as it explicitly says for driveways.
The other roll is a mesh, so is obviously permiable. This stuff says "Heavey duty rough ground cover" - "ideal for under pathways, patios and decking". - but maybe this stuff is not strong enough for a driveway?
