Avoid Costly Oversights
This is a photo of a house built in Victor Harbor, Adelaide South Australia which is built on stumps. As you can see this stump is sitting on a paver which is sitting on dirt. Basically this is a big red light! If any water washes beneath this property it can quite easily remove some dirt away from beneath the paving, causing it to sink. This would of course result in damage to the flooring above and significant repair costs.
