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 Pequea

Southern schist uplands

Pequea is where Pequea Creek finishes its run to the Susquehanna, and the village packs into the low ground where the two meet, with steep river hills rising behind it. A lot of the homes are older. Some were built or used as seasonal places, and many sit close to the water at the bottom of a long slope.

That gives a Pequea basement two separate sources of water. The first is the hill. Rain lands on thin soil over schist, runs along the top of the rock, and reaches the back wall of any house built against the grade. The second is the creek. Pequea Creek drains a large piece of the county, and after a heavy storm it can climb quickly, lifting the groundwater under homes on the low ground. Hill water arrives slowly through the uphill wall over several days. Creek water comes up through the floor and the cove joint within hours.

We sort out which source you are dealing with before quoting, and often it is both. The uphill wall gets a footing drain. Low lots get a sealed basin with a high-capacity pump and a battery backup, since the storms that raise the creek tend to knock the power out as well, and a check valve so pumped water cannot fall back into the pit. For a house that sits empty for weeks we add a high-water alarm. The written estimate is free.

What we install in Pequea

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

  • Springs or wet ground in the yard that never dries out

Questions from around Pequea

Straight answers

Our basement only floods when Pequea Creek comes up. Can waterproofing help with that?

It helps with groundwater pushed up by the creek, which is what floods most Pequea basements. A sealed sump with a high-capacity pump handles water coming up through the floor. If the creek itself pours in over the ground, that's a flood event, and we'll be straight with you about what a basement system can and can't stop.

How fast does water come in after a big storm?

It depends on which source you're seeing. Water from the creek side can show up through the floor within hours. Water from the hill behind the house arrives slowly through the back wall and keeps coming for days. Pequea homes often get both, one after the other.

We only use the house in summer. How do we know the pump is working?

We fit a high-water alarm and a battery backup, so the system keeps running through an outage and warns you if the water climbs. For seasonal homes in Pequea we also recommend a quick pump test before you close up for winter.

The power always goes out in the same storms that raise the creek. What happens then?

That's exactly why the battery backup matters here. The backup pump takes over when the power drops, which is usually the moment the groundwater is rising fastest. We size it so it can keep up through a long outage.

Does a house halfway up the hill in Pequea still need a sump?

Often, yes, but for a different reason. Higher up, the creek matters less and the hill matters more, so the water arrives through the uphill wall. A footing drain along that wall feeding a sump is usually the right fit.
