Preventative Maintenance
Stop Your Driveway From Cracking Before It Starts
Atlanta builders use the same cheap plywood expansion joints you'll find everywhere — and Metro Atlanta's roughly 50 inches of annual rain funnels straight through them, eroding the soil under your concrete faster than in drier climates. We replace them with weatherproof silicone that seals out moisture and protects your driveway for years.
Most jobs start at $1,400 + $12/additional ft
See Why This Matters
Watch John from Hill Country Slabs explain how unsealed expansion joints damage your driveway — and what you can do about it.
The Problem With Plywood Joints
Builders use plywood because it's cheap and fast. But it creates serious problems for your driveway over time.
Water Infiltration
When it rains, unsealed joints act as troughs that funnel water directly under your concrete — right where it does the most damage. At roughly 50 inches of rain a year, Metro Atlanta gives those joints far more water to funnel than drier climates do.
Soil Erosion
Water moving through the saprolite beneath Metro Atlanta driveways carries fine soil particles away, hollowing out voids under the slab while the surface above looks undisturbed — this is especially aggressive here, where rainfall runs half again what a drier climate like Austin sees.
Cracking & Sinking
Weakened soil means your slabs crack and sink. What starts as a $1,400 preventative fix becomes a multi-thousand dollar repair.
Our Solution: Weatherproof Silicone
We remove the old material and seal your expansion joints with professional-grade silicone.
Remove Old Material
We clean out the rotting plywood, debris, and sediment from every expansion joint in your driveway.
Prep & Backer Rod
We install backer rod to the proper depth, ensuring the silicone bonds correctly and flexes with seasonal movement.
Seal With Silicone
We apply weatherproof silicone that blocks water and stays flexible through Atlanta's 40-60 annual freeze-thaw cycles — the exact movement that cracks a rigid filler — so it looks clean for years.
