Building Water Leaks

Symptom guide

Wet Basement Or Floor

Ground water, drainage or a plumbing loss? The distinction decides the fix.

Basement water can be groundwater, a failed drain, a foundation issue or a plumbing loss. Testing tells them apart, and the answers lead to very different repairs.

What to check yourself

  • Note whether it follows heavy rain or plumbing use
  • Check the floor-wall joint and floor drains
  • Look for efflorescence on the walls

Likely causes

  • Groundwater through the envelope
  • A drain or sump failure
  • A below-slab plumbing loss

What the investigation does

  • Moisture mapping and drain testing
  • Isolation of pipes under the slab
  • Drainage and repair recommendations

Quick answers

What should I do first about this?

Moisture mapping and drain testing

Can this be fixed without opening everything?

In most cases the investigation narrows the target before any finish is opened. Small access points are sometimes needed to confirm a finding, and that is discussed before anything is opened.
