FAQ

Clear answers before work begins.

Is every wet basement a waterproofing problem?

No. Water can also come from plumbing, sewer backup, a failed sump system or surface water entering through an opening.

Is interior or exterior waterproofing better?

The better approach depends on the source of water, access, foundation condition, drainage and the property layout.

Can a crack be repaired without full waterproofing?

Sometimes. The correct repair depends on the crack, water path and surrounding foundation conditions.
