Foundation drainage, footing drains, and sump discharge

Normal function

They limit hydrostatic pressure and keep rainwater and groundwater from entering basements, crawlspaces, slabs, or wall assemblies.

What a homeowner may notice

• Damp crawlspace, basement seepage, efflorescence, wet foundation wall, sump cycling, discharge too close to the home, or soil saturation.
• Water appears only after heavy rain and correlates with gutter overflow or a buried leader.
• Cracks, settlement, blocked footing drain, failed pump, or missing backup/overflow route.
• Mold-like odor or wet insulation in the crawlspace.

Professional inspection

Start with roof and surface drainage, then inspect foundation grade, downspout discharge, sump pit/pump/check valve, accessible footing drain outlets, vapor barrier, wall cracks, and moisture readings. Separate plumbing leaks from stormwater.

Repair or replacement path

Correct the roof-to-site water path first, then clean/repair leaders or footing drain outlets, waterproof or seal appropriate cracks, service the sump, and design an interior/exterior drain system when needed.

Typical materials and equipment

Solid/perforated pipe as designed, sump pump/check valve, discharge pipe, waterproofing, sealant, gravel/geotextile, cleanouts, and restoration materials.

When to act

Active foundation water and failed sump discharge deserve prompt attention, especially before heavy rainfall.

What moves the price

Water source, excavation, depth, foundation type, soil, access, pump/electrical, interior finish, waterproofing, and engineer/design needs.
