Basement waterproofing in Murfreesboro
Fewer houses around Murfreesboro have a basement than a crawl space, and a basement that takes in water needs a different fix. Call to be connected with an independent local waterproofing company.
How an interior system works
Interior waterproofing does not try to hold water back at the wall. It accepts that some will reach the foundation and gives it a controlled path out.
A narrow strip of the floor slab is cut away along the walls that leak. A perforated pipe is laid in gravel in that channel, beside the footing. Water coming through the wall, or up at the joint between wall and floor, drops into the pipe and runs to a basin, where a sump pump sends it outside. The channel is then covered with fresh concrete.
On the walls, a plastic sheet or dimpled panel may be fastened from the top down, so that seepage runs behind it into the drain instead of across the room.
What gets disturbed
This is indoor demolition on a small scale. A concrete saw or jackhammer is loud and dusty, even with dust control. Anything stored along the walls has to be moved to the middle of the room or out of it.
In a finished basement, the bottom of the drywall and the flooring along the wet walls usually have to come out, and putting them back may not be part of the waterproofing price. The new concrete strip will not match the old floor in color. Ask how the stairs, the furnace and the water heater will be worked around.
Inside or outside?
Many basements can be handled either way. The exterior waterproofing page covers the outdoor route.
Interior drain system
- Installed from inside, in any season.
- Leaves the yard, deck and planting alone.
- Depends on a pump, so it needs power or a backup.
- The wall still gets wet on its outer face.
Exterior waterproofing
- Stops water before it reaches the wall.
- Needs a trench down to the footing.
- Can drain by gravity where the lot slopes away.
- More upheaval outdoors, less indoors.
Questions for a basement proposal
- Which walls will get a drain, and why not the others?
- Where will the sump basin go, and where does the discharge pipe end?
- Is a battery backup pump in the price?
- Who removes and replaces drywall, flooring and stored items?
- How is dust kept out of the rest of the house?
- Roughly how many basement systems do you put in each year around here? Crawl spaces are far more common, so it is worth asking.
Basement waterproofing questions
Will paint-on sealer do the job?
Waterproof paint can slow dampness coming through sound masonry. It will not hold back water under pressure, and it peels where salts push through. Treat it as a finish, not a fix.
Does interior waterproofing make the basement fit to finish?
It manages water that reaches the foundation. Whether the room is then dry enough for carpet and drywall is a question to ask the company directly, and to judge over a wet season before spending on finishes.
My basement only leaks in the heaviest storms. Is a full system needed?
Not always. Start with gutters, downspouts and the slope of the soil. If the water comes in at one crack or one window, a targeted leak repair may be enough.
