Medford's rain comes in a concentrated season, with December and January the wettest months. When soil around the house stays saturated for weeks, water finds every crack, tie hole and gap where the wall meets the floor. Downspouts that dump next to the foundation and yards that slope toward the house make it worse.
Waterproofing works best when it starts outside: gutters, downspouts and grading are the cheapest fixes. If water still gets in, the options are crack injection, an interior drain with a sump pump, or exterior waterproofing of the foundation walls.
From least to most invasive:
Sloping soil away from the house and extending downspouts several feet out keeps a lot of water off the walls in the first place.
If water comes in through a specific crack, polyurethane injection seals it from the inside.
A drain channel along the inside of the footing collects water and sends it to a sump pump. It's the most common fix for recurring seepage.
Excavating around the foundation to apply a membrane and install drains stops water at the wall. It's the most thorough fix and is easiest in Medford's dry season.
