Hello, I wish to put gravel in my garden. What is the best solution, geotextile or stabilization slab and / or both? Thank you for your reply.
The slab is never a good solution under the gravel because it tends to induce stagnation of the water. Instead, place your gravel on a bed of sand. You will first have to disburse the ground a few centimeters, flatten it, then cover the ground with a geotextile felt that will let the water and the air but avoid the rest of the weeds undesirable. tamp the sand well with a manual or motor lady. Finally you will just add your layer of gravel to complete the work.
