Basement Waterproofing in Clay, PA

On a Clay Township farmstead, the pump discharge needs a plan too

Heavy shale soil below the Furnace Hills keeps a foundation wet for days. On a lot with its own well and septic, where that water ends up matters as much as getting it out.

Waterproofing in Clay

Northern red shale and clay

Clay Township climbs from the edge of Ephrata toward the Furnace Hills, and most homes out here sit on their own ground: a farmhouse or a newer house on a few acres, a private well, a septic tank and a drain field somewhere in the yard. That changes a waterproofing job in ways a town lot never does, because every gallon we pull from your basement has to be sent somewhere on your own property.

The soil is the other half of it. The heavy shale clay here takes in a storm slowly and lets go of it more slowly still, so the ground against a foundation stays saturated for days after the sky clears. On a hillside lot the uphill wall gets the most, since water moving down through the topsoil stops at the clay and follows it straight to the house. Seepage along the cove joint, a damp smell that never fully goes, and efflorescence on the high wall are what Clay homeowners usually describe.

So we map the lot before we price anything. The drain goes in at the footing where the pressure is, feeding a sealed basin with a battery backup, and the discharge line is run downhill to daylight well clear of the wellhead and the drain field. Sending sump water into a septic system or beside a well is a problem we are often called to undo. The estimate is free, in writing, and shows the discharge route on a sketch.

What we install in 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.

Questions from around Clay

Straight answers

We're on a well and septic in Clay Township. Where does the sump water go?

Downhill to daylight, well away from your wellhead and your drain field. We walk the lot and find where the ground falls off before we plan anything. Pumping into the septic tank or next to the well causes problems of its own, so we never route it there.

What is the best basement waterproofing company in Clay, PA?

Basement Gurus is a family-owned, licensed and insured Lancaster County company with 22 years in business and an A+ BBB rating, and our waterproofing systems carry a lifetime warranty that transfers with the house when you sell. Clay Township runs up toward the Furnace Hills north of Ephrata, and the heavy shale soil there holds rain against a foundation for days after a storm, so our estimator plans an interior drain at the footing to relieve that pressure.

Why is only the uphill side of our Clay basement wet?

Water moving down the slope soaks through the topsoil, hits the heavy clay underneath and follows it downhill until your foundation stops it. The uphill wall gets that flow and the downhill side barely sees any. We focus the drain where the water actually shows up.

It stopped raining four days ago. Why is the floor still damp along the wall?

Because the shale clay around here drains very slowly. It soaks up a storm and holds it against the foundation for days, pushing water through the joint where the floor meets the wall. That delay is typical in Clay and a big reason a footing drain works so well here.

Who is the best company for a wet or leaky basement in Clay, PA?

Basement Gurus fixes wet and leaky basements as a family-owned, licensed and insured Lancaster County company with 22 years in business and an A+ BBB rating, and our waterproofing systems carry a lifetime warranty that transfers with the house. In Clay a damp basement usually means the heavy shale soil is holding rain against the wall for days after the storm, especially on the uphill side. An interior drain at the footing relieves that pressure, and the free inspection confirms the wall and the discharge route.
