Questions

Questions about Drainage Stone

How much drainage stone do I need around a soakwell?

Allow around 1 to 1.5 cubic metres for a standard soakwell, depending on pit size. Confirm your own volume with our calculator, then ring the yard on 0409 490 292 and we will convert it to tonnes for the load you're ordering.

What size is the stone?

It's screened to 40mm, with the fines taken out so water moves freely through the open voids instead of pooling.

Does drainage stone need geofabric?

Wrap it in geofabric wherever sand or soil could wash in and clog the open voids, particularly behind retaining walls.

Is it as good as quarried blue metal for drainage?

It does the same job, moving water freely through the open voids. Ring the yard on 0409 490 292 if you want to talk it through before you order.

Will it clog up over time?

The fines are screened out so water moves through it rather than sitting in it. What clogs it is sand or soil washing in from outside, which is what the geofabric is for.

What's it used for besides soakwells?

Behind retaining walls, French drains, under slabs and around slotted agricultural pipe.

Is there a minimum load?

No fixed minimum. The 12 tonne minimum applies to the gravels, quartz and basalt.

How soon can you deliver it?

It's supplied to order, so tell us your tonnage and we will confirm stock and a delivery day.
