Grade D Sand

Washed Treepit Subsoil

One of our medium/coarse washed sands used in the base of tree pits for optimum drainage.

Description

In order to move the water away from the base of the tree pit we would recommend a layer of a washed medium coarse silica sand. Our Grade D sand drains at around 470mm per hour and is perfect for laying in the bottom of your tree pit. We have other sands available if this does not suit your specification.
