Basement Waterproofing in Lancaster, PA

Stop the water, keep the room.

A dry basement is a drainage problem, not a paint problem. We relieve the water pressure under and beside your foundation and give the water somewhere to go, so the room stays dry through the wettest spring Lancaster County can produce.

Interior waterproofing at the footing, in cross-sectionCutaway through soil, a concrete block foundation wall, and the basement floor and framing beside it. Water seeps down through the soil on the left and gold arrows show it pressing against the wall. A green wall vapor barrier runs down the inside face of the block and turns into a sealed cove joint where the floor meets the wall, with a gold wedge marking the joint water would otherwise enter through. Below the floor slab, a green perforated drain pipe sits in a gravel bed at the footing and runs right into a sealed green-lidded sump basin, whose discharge line rises and carries water off to the right, away from the house.GradeWall vapor barrier over blockCove joint, sealedPerforated drain in a gravel bed at the footingDischarge, routed away from the house

How the system works

Interior drainage, in cross-section

Not to scale · every install is sized to the house
Interior drainage, in cross-sectionCutaway through the soil, the block foundation wall and the basement floor of a house. Rainwater falls from a downspout and seeps down through saturated soil on the left, pressure arrows push it sideways against the wall, and a drainage system set into the floor on the right carries it away. Five numbered callouts. One, gold: rain and snowmelt saturating the soil against the wall. Two, gold: water forced through the block and in at the cove joint where floor meets wall. Three, green: a perforated drain pipe in a gravel bed at the footing, below the slab. Four, green: a sealed sump basin with a cast-iron pump and battery backup. Five, green: the discharge line running water away from the foundation.12345GradeWall vapor barrier
  1. The problem: Rain and snowmelt saturate the soil against the wall. Downspouts and grade decide how much arrives.
  2. The problem: Pressure pushes it through the block and in at the cove joint where floor meets wall.
  3. The system: A perforated drain in a gravel bed at the footing intercepts the water before the floor does.
  4. The system: It runs to a sealed sump basin with a cast-iron pump and battery backup for outages.
  5. The system: Discharge is routed far enough from the foundation that it does not simply come back.

Where you live changes the job

Basement Waterproofing on limestone is not basement waterproofing on red shale

Lancaster County has four distinct ground conditions, and each one changes how we size and place this work. Your town page has the specifics.

Limestone valley floor

Interior French drain tied into a sealed sump basin with a battery backup, because the volume shows up fast and all at once. Wall vapor barrier where the block has been wicking.

Northern red shale and clay

Interior drain at the footing to relieve the pressure, plus wall reinforcement (carbon fiber or steel) anywhere the block has started to move. Exterior grading and downspout extensions to stop feeding the clay.

Southern schist uplands

Drainage on the uphill side first — interior drain plus exterior interception where the grade allows — and a discharge line routed far enough downslope that it does not simply return.

Susquehanna river terraces

Sub-slab drainage with a high-capacity sealed sump and battery backup, mortar repointing on stone walls, and encapsulation where the space is unfinished.
