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

Waterproofing in Terre Hill

Northern red shale and clay

Terre Hill is on high ground, which sounds as though it ought to be good news for a basement. That is only half the story. Being high means surface water arrives fast and with momentum behind it, off the slopes above you and off the roofs and driveways of everything upstream.

The other half is what it lands on when it gets there. The soil in this borough is heavy, and it does not take that arriving water down and away. It holds it at the surface and through the first few feet, which is exactly where your foundation wall is standing. Terre Hill hands you the arrival speed of a hillside and the drainage of a clay pan on the same property.

The work therefore comes in two halves. Outside, interception before any of it reaches the house: a swale, a run of exterior drain, downspouts carried well past the wall. Inside, a footing drain and a sealed basin with a battery backup for whatever still gets through. On a lot like this the exterior half regularly does more of the work than owners expect it to.

What we install in Terre Hill

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 Terre Hill

Straight answers

We are at the top of the hill. Why are we the ones with water?

Because height gets you the runoff and the soil keeps it. Water arrives fast off the slopes and roofs above, and the heavy ground in Terre Hill won't take it away downward. So it stays in the first few feet, right where your wall is.

Water comes across the driveway in sheets during a storm. Where should it go?

Into a swale or an exterior drain that carries it around the house before it reaches the wall, which is standard on a Terre Hill lot. On a lot like that, intercepting surface flow is the single highest value thing we can do, and it usually costs less than people assume.

Is exterior work enough on a Terre Hill lot, or do we need both?

Often the exterior does the bulk of it here, which is unusual and worth knowing. We'd normally do the outside first, watch it through a storm, and add the footing drain only if water is still getting through. You pay for the second half when it's earned.

How much of the yard gets dug up for a swale?

A single line across the uphill side, restored and seeded when we're done. It's one to two days on a typical lot. The estimator marks the route with you before anything starts so there are no surprises about where it runs.

The soil out here is like modelling clay. Does that change the drain design?

It changes the stone and the fabric we use around the pipe, because heavy soil will silt a poorly built drain shut in a few years. Proper filter fabric and washed stone are what keep it open. It's not visible once it's covered, and it's the difference between ten years and forty.
