Waterproofing in Conestoga
Southern schist uplands
Conestoga Township is river hill country. The land climbs steeply from the Susquehanna, ravines cut down through it toward the water, and many houses sit along roads that follow a slope, with the yard falling away on one side and climbing on the other. Some began as small cabins or summer places that were enlarged and winterized over the years, so the basement underneath is often a patchwork of old wall and newer block.
Under all of it is schist, a short way down. Rain soaks into a thin layer of soil, meets rock it cannot pass, and moves along the top of the bedrock toward the river. On a hillside lot that flow runs straight into whichever wall is cut into the slope. In a ravine it can arrive from two sides at once, because the ground falls toward the house from the head of the hollow as well as from the hill behind it. Seepage tends to start a day after a storm and trickle on well into the following week.
On a Conestoga job we find where the wall is buried deepest and where the water shows first, then run the interior drain along that stretch of footing into a sealed basin with a battery backup. Where an older section meets an addition we seal the seam, a favourite entry point. Discharge on a steep lot needs a planned route and an outlet that will not scour the bank below it. All of that is written into a free estimate before any work is scheduled.
What we install in Conestoga
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 Conestoga
Straight answers
Our house sits at the head of a ravine and water comes in on two walls. Is that unusual?
Not in Conestoga Township. A ravine funnels water toward its head from the sides and from above, so a house there can take seepage on the back wall and a side wall at the same time. We drain both stretches of footing and leave the dry walls alone.
Our place started as a summer cabin and the basement is half old wall, half new block. Where does the water get in?
Usually right at the seam between the two. The old section and the addition were built years apart on different footings, and that joint moves just enough to let water through. On a lot of Conestoga homes sealing that seam and draining beside it takes care of most of the problem.
Can you run a discharge line down a steep bank without washing it out?
Yes, but it needs planning. We pick a route with steady fall, anchor the pipe, and finish the outlet with stone so it doesn't cut a gully into the hillside. On the river hills around Conestoga that outlet detail matters as much as the pump does.
Why does our leak only start the day after a storm has passed?
Because the water has to travel. It lands up the slope, soaks through thin soil, and then runs along the top of the schist until it reaches your wall. That trip takes time, which is why hillside seepage lags behind the rain and hangs on for days afterward.
Is there any point sealing the inside of the walls in Conestoga?
A coating alone won't hold back water that's being pushed along the rock with the whole hill behind it. What works is relieving the pressure with a drain at the footing and a sealed sump. A wall membrane can go on after that to keep the room dry and tidy.
