Basement Waterproofing · Cambridge
Interior vs Exterior Waterproofing
Two approaches, different costs and use cases. Here's how to tell which you need.
The right Cambridge waterproofing method depends on the water source.
Interior systems
Perimeter drainage and a sump manage water that gets in — less disruptive and lower cost.
Exterior systems
Excavation and membrane stop water at the wall — more involved, best for persistent outside pressure.
Which do you need?
We assess the source and recommend the lightest fix that works — see waterproofing.
A proper diagnosis saves you from over- or under-fixing.
Frequently asked questions
Is interior waterproofing enough?
Often, for seepage — but persistent exterior pressure may need excavation. It depends on the source.
