If any of this is happening, call us

Georgia clay does not forgive a bad wall.

Heavy red clay holds water, swells, and pushes. That pressure is what tips walls over and floods yards. Here is what we get called for most.

Wall is leaning or bulging

Cross-tie and timber walls rot and tip. Once a block wall bows out, it is holding on borrowed time.

Water stands in the yard

Puddles that last for days after rain mean the grade sends water to the wrong place.

Slope is washing away

Every storm carries more topsoil down the hill and cuts channels through the lawn.

Water reaching the foundation

Wet crawl spaces and damp basement walls almost always start with grading and downspouts.

Backyard too steep to use

A terraced wall turns a hill nobody walks on into flat ground for a patio, a pool pad or a lawn.

Driveway cracking or sinking

When the soil under a slab moves, the slab follows. Fix the ground first, then the concrete.

Retaining walls

Modular block, natural stone and pressure-treated timber walls — from a 2-foot garden wall to structural walls that hold a driveway or a house pad.

Grading, excavation & drainage

We reshape the ground so water leaves the house instead of collecting against it, and turn unusable slope into flat, usable yard.

  • Yard leveling and pad prep
  • French drains, catch basins, downspout lines
  • Erosion control and land clearing

How we build

Most of a good wall is buried where you will never see it.

Anyone can stack block. Walls fail because of what happens under and behind them. This is the sequence we follow on every job, and we will show you each stage as we go.

1

Dig and cut the bench

We excavate below grade and cut a level bench into solid, undisturbed soil — never on loose fill.

2

Compact the base, level the first course

Crushed stone base, compacted in lifts. The first course gets leveled block by block — every course above copies it.

3

Drainage stone and geogrid

Perforated pipe, clean stone backfill and geogrid tied into the soil behind the wall. This is what stops the lean.

4

Build up, cap, finish the grade

Courses go up with the right setback, caps get glued down, and we regrade and clean the site before we leave.

How we are set up

Four crews. Each one does one thing all day.

Most contractors send the same three guys to pour concrete on Monday and lay flagstone on Tuesday, or they hand your job to a sub you never meet. We do not. Each trade has its own crew, its own lead and its own equipment — and they all answer to us.

CREW 01

Earthwork & walls

The machine operators. They cut the slope, set the base and build block and timber walls.

  • Skid steer and mini-excavator
  • Block, stone and timber walls
  • Grading, drainage, geogrid
CREW 02

Pavers & natural stone

The pattern guys. Screed, cut, lay and lock — patios, walkways and fire pits.

  • Paver patios and walkways
  • Flagstone and bluestone
  • Fire pits, steps and seat walls
CREW 03

Concrete

Forms, rebar, pour and finish. Driveways and walkways that get jointed right so they do not crack.

  • Driveways, aprons, sidewalks
  • Tear-out and replacement
  • Slabs, pads and footings
CREW 04

Finish & landscape

The ones who make it look finished — sod, beds, mulch, lighting and a clean site the day we leave.

  • Sod, topsoil and plant beds
  • Mulch, pine straw, edging
  • Low-voltage lighting and cleanup

What that means for you: on a big job the crews overlap instead of waiting on each other. The wall crew finishes and the paver crew is already on site the next morning — so a project that takes another company six weeks takes us two or three.

Before and after

Rotted cross-ties out. Timber walls and steps in.

This backyard had three old railroad-tie terraces that had rotted through and were sliding down the hill. We tore all of it out, hauled it off, and rebuilt with pressure-treated timber tied back into the slope, with steps between the levels.

Why homeowners pick us

A wall is only cheap once.

The owner is on your job

You meet the person who builds the wall, not a salesman who hands it to a sub you never see.

Written price, no surprises

Materials, block count, drainage and haul-off itemized before we start. If the ground changes the plan, you approve it first.

Drainage included, not upsold

Pipe, clean stone and fabric are part of the wall. Skipping them is the number one reason we get called to replace someone else's work.

Photos at every stage

We send progress photos of the base, the pipe and the geogrid — so you can see the work you are paying for before it gets buried.

Clean site at the end

Spoil hauled off, ruts regraded, driveway swept. Your yard should look finished, not survived.

What customers say

Neighbors who stopped worrying about the hill.

★★★★★

Our old cross-tie wall was leaning into the driveway. They tore it out, put in block with real drainage behind it, and hauled everything off the same week. Two heavy storms since and it has not moved.

★★★★★

Back half of the yard was a swamp every spring. They regraded it, ran a french drain to the street and laid sod. The kids can finally use it.

Marcus T.Lawrenceville, GA
★★★★★

I got three quotes. They were the only ones who explained the geogrid and sent me photos of it going in. Price held exactly to the estimate.

Questions we get every week

Straight answers before you spend anything.

Most residential block walls land between $35 and $70 per square foot of wall face, measured height times length. Access, wall height, drainage and how much dirt has to be hauled off move the number more than anything else. Walls over about 4 feet usually need engineering, which adds cost but is not optional. We give you the full breakdown in writing so you can compare bids line by line.
For metro Atlanta, budget roughly $18 to $32 per square foot installed for concrete pavers, and $28 to $45 for natural flagstone or bluestone. A 300 to 600 square foot patio is usually 4 to 7 working days. Steps, fire pits, seat walls and any grading or drainage the yard needs are quoted separately so you can see exactly what each piece costs.
It depends on your county and the wall height. In most metro Atlanta jurisdictions a wall over 4 feet from the bottom of the footing, or any wall with a surcharge like a driveway above it, needs a stamped design and a permit. We tell you up front which category you are in and handle the paperwork and the engineer coordination.
Sometimes. If the base is sound and only the top courses have shifted, a rebuild of the upper section plus new drainage can work. If the wall is leaning at the bottom, the base or the drainage failed, and patching the top is money thrown away. We will tell you which one you have even if the honest answer costs us the job.
A typical residential wall of 30 to 60 feet runs 3 to 6 working days once we start. Grading and drainage jobs are often 1 to 3 days. Rain moves schedules — clay has to dry enough to compact — and we would rather wait a day than build on mud.
We plan the access route with you before day one, use plywood or mats on turf where we can, and regrade and reseed any ruts we make. Cleanup and repair of the access path is part of the price, not an extra.
Yes. A good part of our work is site prep, pad grading and structural walls for new construction, plus repeat drainage and erosion work for HOAs and rental portfolios. We carry general liability and workers comp and can send certificates before we mobilize.
Yes. The whole crew speaks Spanish and English, and this site works in both. Call, text or WhatsApp in whichever you prefer.
