Basement encapsulation
Basement encapsulation in Louisville, KY
Walls lined, the perimeter drained to a sealed sump, and the floor closed and sealed, so the whole basement is dry and usable. Installed by our own crew and backed by a lifetime transferable warranty.
Signs you need it
When a basement needs the whole system
Water at the floor edge after rain
Water that shows up where the floor meets the wall is pushed in by the water table rising in Louisville clay.
White powder or dark stains on the block
Efflorescence is minerals left behind by water moving through the wall. The wall is wet inside.
Damp smell and peeling paint
Long-term humidity in a basement corrodes metal, lifts paint and feeds mold behind finished walls.
A basement you want to use
Storage, a workshop or a room you plan to finish later all need dry walls and a dry floor first.
What we do
Lined walls, a drained perimeter and a sealed floor, as one system
Basement encapsulation is our interior basement system taken all the way around the room. The perimeter of the floor is opened, perforated drain tile goes in washed gravel at the footing and runs to a sealed sump basin and pump. The walls are covered with a liner, sealed at the top, so any water that comes through the block runs down behind it into the drain instead of across the floor. The channel is closed with new concrete, the floor is sealed, and the discharge is run outside and away from the house.
It is the same drainage our basement waterproofing page explains, with the liner on every wall. If you only need the walls dealt with, the basement wall system page covers the liner on its own terms. Furnaces, water heaters, softeners and posts stay where they are: we work around them.
- Perimeter drain tile at the footing, feeding a sealed sump
- Wall liner sealed at the top, fitted around utilities and posts
- Floor closed with new concrete and sealed, site cleaned

How the job goes
Two to three days for a typical basement
Inspect
We find where the water gets in, check the grading and downspouts outside, and photograph the whole basement.
Open the perimeter
The floor edge is cut and the concrete removed. Dust is controlled and the area is sheeted off.
Drain, liner, sump
Drain tile and gravel go in, the liner goes up the walls, the sump basin is set and the pump connected.
Close and seal
New concrete over the channel, the floor sealed, the discharge run outside, everything tested.

Questions
Basement encapsulation: what people ask
Still have a question? Call the office, Monday to Saturday, 9:00 AM to 5:00 PM.
How much does basement encapsulation cost?
It is priced by the length of the perimeter, how much of the wall gets liner and what the basement is used for. Every job is priced in writing after a free inspection, and the cost guide has typical Louisville ranges and a calculator for planning.
Is basement encapsulation the same as basement waterproofing?
It is our interior basement waterproofing system with the liner on every wall: drain tile at the footing, a sealed sump, lined walls and a sealed floor. The basement waterproofing page also covers exterior work, crack repair and downspouts.
Do I need the whole system, or just the walls?
It depends on where the water gets in. The inspection shows whether the floor edge, the walls or both are the problem, and the written estimate says which work your basement needs and why.
What happens to my furnace, water heater and softener?
They stay where they are. The perimeter is opened around them and the liner is fitted behind and around fixed equipment.
How long does it take?
Two to three days for a typical basement. The written estimate gives you the schedule for your house.
Is the warranty transferable?
Yes. The lifetime warranty on our work transfers to the next owner when you sell. The warranty page explains how it works.
Do you do this outside Louisville?
Yes. We are based in Louisville and work across Jefferson County, the surrounding Kentucky counties and southern Indiana. The service areas page lists every town we cover.
