Macon, GA Exterior Basement Waterproofing

The water stops outside.

Most companies wait until water is already inside, then pump it back out. We excavate to the footing, seal the wall and drain it away before it ever reaches you.

There are two ways to deal with a wet basement.

Almost every company in Middle Georgia sells the one on the right. It is faster, it is cheaper to install, and it never touches the reason the water is there.

What GRC does. Exterior.
OUTSIDE INSIDE DRY Nothing to pump. Nothing to run. 1 2 3 1 Membrane sealsthe outer face 2 Gravel backfillkeeps it moving 3 Drain at the footingcarries it away

Stop it at the wall

  • The wall is dug out and exposed all the way to the footing.
  • A waterproof membrane goes on the outside face of the wall.
  • Cracks get repaired while they are reachable.
  • A French drain and gravel backfill carry water away from the footing.
  • Hydrostatic pressure against the wall drops.
  • Nothing has to run, and nothing has to be maintained.
The common alternative. Interior.
OUTSIDE INSIDE SOIL NEVER TOUCHED WET, THEN PUMPED The water still gets in. A machine sends it back out. 1 2 3 1 Water comes inthrough the wall 2 Floor cut openfor a channel 3 Sump pumpneeds power

Let it in, then pump it

  • The soil against the wall is never touched.
  • Water still passes through the wall, by design.
  • The basement floor gets cut open for a perimeter channel.
  • A sump pump moves the water back outside.
  • The wall stays wet and the pressure stays on it.
  • The dry basement now depends on a pump and on the power staying on.

Their own words for it, and ours: we are real excavation experts, not patchwork fixers. Digging is harder, slower and more disruptive than drilling a hole in your slab. It is also the only version that removes the cause.

Zero sump pumps.

Exterior work removes the cause. Nothing to plug in, nothing to maintain, and nothing to fail in the next storm.

What is it doing?

All six have one cause: water outside the wall with nowhere to go. Pick what you are seeing and it rides along to the quote.

We own the machines.

  1. 01

    Full Excavation

    We dig to the footing and expose the problem instead of guessing at it.

  2. 02

    Wall Sealing

    The foundation wall gets a waterproof membrane on its outer face.

  3. 03

    Protective Coatings

    A durable coating shields the wall from moisture for the long haul.

  4. 04

    Foundation Repairs

    Cracks get closed while the wall is open and reachable.

  5. 05

    French Drains

    Drainage at the footing takes water away from the house.

  6. 06

    Gravel Backfill

    Gravel keeps the flow moving instead of trapping water against the wall.

  7. 07

    Repair Wood

    Joists and girders damaged by moisture get repaired or replaced.

  8. 08

    Clean Mold

    Surface mold in the crawlspace gets cleaned as part of the job.

The worst basements in Middle Georgia are not in the newest houses.

  • Churches and historic buildingsOld foundations were not built for the drainage we expect now. They are the buildings that need exterior work most, and the ones interior systems serve worst.
  • Commercial propertyBusinesses across Middle Georgia, with the work scheduled around your operating hours.
  • Property managersOne dry basement protects the asset. We document what we found and what we did.
  • Homeowners with aging basementsThe most common call: a wall that has been damp for years and finally got worse.

What people ask on the estimate.

An interior system does not stop water. It lets water come through the wall, catches it at the floor and pumps it back out. That leaves the wall wet, the hydrostatic pressure unchanged and your dry basement dependent on a pump and the power staying on. Exterior work removes the cause.

Clay holds water and swells. Around here that means a foundation sits in saturated soil for days after a storm and the pressure pushes water through any joint or crack it can find. That is why the fix belongs outside the wall, in the soil, not inside on the floor.

No, and we do not pretend otherwise. We clean surface mold in crawlspaces with a three step process. Remediation is a separate licensed scope. If what you have needs remediation, we will tell you that instead of selling you a cleaning.

Yes. Churches, historic buildings and commercial property are a regular part of the work, alongside houses. Older foundations usually need the exterior approach more than newer ones do.

Nothing. Estimates are free and the inspection comes with a plain explanation of what we found and what your options are, including the option to do nothing yet.
