Gap, PA — Southern schist uplandsLocator card for Gap, Salisbury Twp, ZIP 17527, in Lancaster County, PA. The town name is set across the top of a dark banner. Below it, a cross-section of the ground this town is built on — the Southern schist uplands — shows an irregular ridge of schist bedrock breaking up toward the surface, its foliation ruled through it in fine parallel lines, split by 3 steep joints and crossed by two quartz veins, with water running sideways across the top of the rock toward the right.LANCASTER COUNTY, PASOUTHERN SCHIST UPLANDSGapZIP 17527 · Salisbury Twp

The ground under Gap

Southern schist uplands

Piedmont schist and quartzite with shallow bedrock — the hill country below Route 30.

There is often only a few feet of soil over rock down here. Rain cannot go down so it goes sideways, riding the top of the bedrock until it hits the uphill wall of your basement. That is why so many homes on these slopes leak on exactly one side, and why the leak follows the hill rather than the storm.

What we install in Gap

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.

Most common call here

  • Water always enters on the same uphill wall
  • Springs or wet ground in the yard that never dries out
  • Seepage that continues for days after the rain stops
  • Rusty staining where iron-rich water has been running

Questions from around Gap

Straight answers

Do you actually work in Gap?

Yes — regularly. Our office is at 2348 Harrisburg Pike in Lancaster, and Gap (Salisbury Twp) is a routine stop for our crews. Ask for the Gap photos when the estimator comes out.

What does a job in Gap usually cost?

It depends on how much wall needs draining and what the ground is doing. The estimate is free and in writing before anything starts, there is no money down, and financing is available.

Why does my neighbor need a different system?

There is often only a few feet of soil over rock down here. Two houses on the same street can sit on different grades and take water differently, which is why we read the water path before quoting.

How fast can you get here?

Free estimates in Gap are usually within a few days, and we run 24/7 emergency service when there is active water in the house.

Is the warranty transferable if I sell?

Yes. The waterproofing warranty is for the life of the home and transfers to the next owner, which is worth having in hand at closing.
