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

Waterproofing in Gap

Southern schist uplands

The village of Gap takes its name from the break in Mine Ridge that the road runs through, which is probably the most useful piece of drainage information a homeowner here could be handed. A gap in a ridge is a low point, and a low point in a landscape is where water goes.

Salisbury Township sits on Piedmont rock with shallow soil over the top, so rain does not travel far downward before it starts travelling sideways. It rides the surface of the bedrock toward the low ground, which is to say toward the notch, which is to say toward the houses standing in it. Seepage in Gap shows on the wall facing the high side and keeps running for two or three days after the sky has cleared.

What we install follows that pattern. The interior drain goes in along the uphill footing where the water actually arrives, exterior interception goes in where there is grade to work with, and the discharge is routed with enough fall that it cannot make its way back. On the older properties we look at what the barn and outbuildings shed as well, since they usually sit further up the slope than the house does.

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

Questions from around Gap

Straight answers

We are right in the notch. Is everyone above us draining onto us?

Effectively, yes. A gap in a ridge is where the landscape sends water, and Gap sits in it. That doesn't make the problem unfixable, it just means interception matters more here than it does on flat ground.

Why does seepage keep going for days after it stops raining?

Because the water is still travelling. It landed somewhere up the slope and it's working down the top of the bedrock toward you, which takes time. That lag is how we tell a hillside problem from a downspout problem in Gap.

The barn sits above the house. Does that need dealing with too?

It usually does, and it's often the cheapest part of the fix. A barn roof above you on a Salisbury Township slope puts a serious volume into the ground uphill of your footing. Gutters and one run of pipe can take a surprising amount of load off the house.

Can you put an exterior drain in if the rock is only two feet down?

Sometimes, and shallow rock is exactly why we look before promising it. Where there's no depth to work with we do the job from the inside at the footing, which works regardless of what the excavator would have hit.

Does being out in Salisbury Township mean a longer wait for an estimate?

Not meaningfully. Gap is about forty minutes from the Harrisburg Pike office and our crews run east on 30 every week. Free inspections out there are usually a few days out, and active water in the house gets treated as an emergency.
