Waterproofing From the Outside In
Exterior waterproofing stops water before it ever touches your basement wall. A contractor digs down along the outside of the foundation, cleans and repairs the wall, coats it with a waterproof membrane, and lays new drain tile at the footing. Then the trench is backfilled and the yard put back.
It's the bigger job, and it costs more than an interior system. But for some Youngstown-area homes it's the right one. Old clay tile outside the footing may have collapsed or filled with roots. A finished basement may be one you don't want torn up. Or the wall itself may need sealing.
Basement Waterproofing Youngstown connects you with established local waterproofing companies that handle exterior work. They're insured, licensed or registered where required, and they put their warranty in writing. This service is free to use.
When Exterior Waterproofing Makes Sense
Your Basement Is Finished
Exterior work keeps water out without cutting into finished floors and walls inside.
The Wall Needs Sealing
Wet walls, cracks or crumbling mortar can be repaired and sealed from outside. Wet wall causes
Old Outside Drains Have Failed
Clay tile that is crushed, root-filled or silted up can be replaced with modern pipe.
Water Comes Through One Wall
A single leaking wall is sometimes easier to dig than to fix inside, especially along an open side yard.
How Exterior Waterproofing Works
- Locate buried lines. Your contractor should have gas, water, power and cable lines marked through 811 before any digging.
- Excavate. The soil is dug out along the wall, down to the footing.
- Clean and repair the wall. Dirt and old coatings come off. Cracks and holes are patched.
- Apply a membrane. A liquid or sheet membrane seals the wall. Many contractors add a drainage board over it so water runs down freely.
- Lay drain tile. New perforated pipe at the footing carries water to a sump or out to daylight.
- Backfill and grade. Gravel and soil go back in, sloped away from the house.
Excavation and Membranes
The membrane is the barrier. Rubberized liquid coatings and peel-and-stick sheets are common, and both work when applied to a clean, dry, repaired wall. Old tar coatings, often found on Youngstown's older homes, crack and wear thin over the decades. They're not the same thing.
Published guides put waterproofing membranes at about $4 to $7 per square foot installed. The digging is what drives the total. How far down the footing sits, the soil, access and how much of the yard is in the way all count.
Exterior Drain Tile
New drain tile at the footing replaces the old clay tile many homes in the area were built with. It's laid in gravel, often wrapped in fabric to keep silt out, and sloped to carry water away. Exterior drains on one side of a house run about $30 to $90 per linear foot in published guides.
What Excavation Means for Your Yard
Expect a trench along each wall being done, with soil piled nearby. Plants, walkways, decks and patios near the wall may need to come out and go back. Driveways next to the house add cost. Ask your contractor what's included in the restoration. Published guides put landscaping repairs after foundation work at about $300 to $1,000 or more.

What to Ask Your Contractor
- Which walls will you dig, and how far down?
- What membrane and drainage board will you use?
- Where will the new drain tile send the water?
- What happens to my landscaping, walkways and driveway?
- Is the warranty in writing, and what does it cover?
Exterior Waterproofing Questions
Is exterior waterproofing worth the cost?
It can be, when the wall itself needs sealing, the basement is finished, or the outside drains have failed. For many basements, an interior system solves the same water problem for less.
Interior or exterior: which is better?
Neither is better for every house. Interior systems manage water that reaches the footing. Exterior systems keep it off the wall. An inspection should explain which one your basement needs, and why.
How long does exterior waterproofing last?
A well-applied membrane with good drainage lasts many years. Ask for the warranty terms in writing, since they vary by contractor.
Will they dig up my landscaping?
Usually, along the walls being done. Plants and pavers near the wall may be lifted and replaced. Ask what restoration is included before you sign.
