What basement waterproofing looks like on site
Interior and exterior waterproofing solve the same problem from opposite directions and cost very different amounts. Interior drain tile manages water that has already reached the wall; exterior work keeps it away. Which is right depends on the wall, the grade and the budget, and both should be explained.
A sump pump without a backup is a system that fails exactly when it is needed, because the storms that flood basements are the storms that take the power out.

FAQ
What does basement waterproofing involve? Common questions
Interior or exterior basement waterproofing?
Interior drain tile and a sump for most existing houses: it is less disruptive, cheaper, and it manages water that has already reached the wall. Exterior membrane and drainage for a wall that can be excavated, or for new construction — it stops the water before it touches the foundation. Crack injection handles a single leaking crack. The right one depends on where the water comes from.
Why does my basement leak only in heavy rain?
Because that is when the water table around the house rises above the floor, or when the gutters overflow and dump water at the foundation. Water follows the easiest path in — a floor-wall joint, a crack, a window well. The first check is always outside: downspouts, grading, and whether the ground next to the house is a bowl.
