Waterproofing Northeast

Interior drain tile

Water along the basement floor?
Start with the cause.

Below-slab drain tile collects groundwater and directs it to a sump. It can be a useful repair when the observed water path supports it, but every puddle does not call for a full system.

Check the simpler causes first

Gutters, downspouts, surface slope, plumbing and window wells can all affect where water appears. Roof water collecting near the foundation deserves attention before a construction recommendation.

We ask where the water starts, when it happens, what has already been repaired and how you use the basement. Sometimes the next step is a surface-water correction, monitoring or another specialist.

What the system does

The pipe and washed-stone zone provide a collection path to a sump. With an appropriate outlet and a scope matched to the water path, the system can lower local water pressure in the drained area and reduce seepage at the floor-wall joint.

It does not make every part of the foundation waterproof. Soil, the treated footprint, pump capacity, discharge and water outside that footprint still matter.

What your visit should answer

  • Does the evidence support below-slab drainage, a targeted repair or a different next step?
  • What exact perimeter, wall drainage, sump and discharge work would be included?
  • What access, concrete restoration, finish work and exclusions affect the quote?

Planning tiers currently span $5,000–$25,500+. Measured footage, footing condition, access and basin scope determine the applicable tier. Explore pricing without giving us your email.

Installation and written coverage
  • Qualifying WPNE drain tile uses 4-inch perforated corrugated pipe and washed 3/4-inch drainage stone at the bottom of the footing, without undermining it.
  • The written footprint identifies the collection path, wall drainage, sump, discharge and concrete restoration.
  • The proposal names the approved American-made Zoeller primary pump. Optional Spin 508 backup and an approved AGM battery are quoted separately.
  • Limited lifetime workmanship coverage applies to the exact qualifying WPNE-installed drain-tile and wall-drainage footprint, subject to the signed agreement. Product coverage is separate.

Read the written warranty terms.

Groundwater pressure, in plain language

Water around and beneath a basement can build pressure and enter through available joints or openings. Drainage manages a defined collection area and gives that water a route to the sump. A wet wall alone does not establish the source or prove that a full perimeter system is needed.

Read the groundwater-pressure guide.

Interior versus exterior work

Interior drainage involves slab access and restoration. Exterior work involves different access, excavation and restoration. Neither is the right answer for every property.

New exterior installations remain closed for the remainder of 2026. Exterior assessments are for 2027 planning. Installation is anticipated in late April or early May, once ground conditions allow. An assessment does not reserve an installation date.
