Groundwater & Basement Water Intrusion in Portland, ME
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.

Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
What is the made ground built out of?
Whatever was to hand when it was placed: rubble, ballast, ash, spoil from other sites, and the timber of the wharves themselves. It was not engineered fill and no record was kept, so what is under a particular building is genuinely unknown.
Why does old timber in the fill matter?
Because it rots when it is not permanently wet, and leaves a void where it was. Wharf timbers buried in the fill survived as long as the ground water stayed above them; where the level has dropped, they have decayed and the ground above has settled.
Does the tide reach these basements?
The ground water does, which amounts to the same thing. The level beneath these streets rises and falls with the harbor, so a basement here can be wet on a high tide and dry six hours later, entirely independently of any rain.
