Cracked, sunken, chipped, or spalling concrete surfaces are more than just unsightly blemishes on your property—they represent serious safety hazards, reduce property value, and allow damaging water to erode underlying sub-base soils. At Brook Concrete Company, we provide comprehensive concrete repair in Dunwoody, GA, restoring driveways, patios, sidewalks, steps, and commercial slabs to safe, beautiful, and durable condition. We believe in providing honest, objective assessments, helping you understand whether targeted repair, resurfacing, or replacement is the most cost-effective path forward.
In north Georgia's climate, where seasonal rainfall saturates expansive red clay soils followed by winter freezes, small surface defects can quickly evolve into major structural failures if left unaddressed. Our team utilizes commercial-grade repair mortars, polyurethane injection compounds, and precision leveling methods to halt concrete degradation and protect your hardscape investment.
Comprehensive Concrete Crack Repair and Joint Sealing
Cracks are the most common complaint among property owners. However, not all cracks are created equal:
- Hairline Shrinkage Cracks: Microscopic cracks that occur as concrete cures and loses moisture. These are typically cosmetic but should be sealed to prevent water penetration.
- Active Settlement Cracks: Fractures where one side of the crack is noticeably higher than the other, indicating subgrade soil movement or washout.
- Structural Diagonal Cracks: Severe cracks caused by heavy vehicle overloads or tree root upward pressure.
We clean out fractures using diamond-wheel grinders, extract debris, and inject high-strength polyurea or elastomeric polyurethane sealants that bond tenaciously to concrete walls. These flexible sealants expand and contract with seasonal temperatures, creating a permanent watertight barrier that keeps moisture from freezing and expanding inside the joint.
Surface Spalling, Scaling, and Chipping Restoration
Spalling occurs when the top layer of concrete flakes off, exposing coarse aggregate stones beneath. This unsightly damage is often caused by trapped moisture, poor original finishing, or improper chemical use. For slabs suffering from surface degradation without deep structural cracking, we mechanically grind the surface clean, apply bonding primers, and install high-strength polymer-modified cementitious overlays that restore a clean, uniform finish.
Leveling Sunken and Uneven Concrete Slabs
When soil beneath a concrete walkway or patio slab settles or washes away, panels can sink several inches, creating dangerous trip ledges. Sinking slabs can also cause stormwater to slope toward your home rather than away. We evaluate the root cause of the settlement. In cases where the underlying base is severely compromised, full concrete driveway replacement or panel reconstruction is the best long-term solution.
Choosing Between Repair, Resurfacing, and Full Replacement
We pride ourselves on honest, transparent recommendations. If your slab has isolated damage and a solid base, targeted repairs will save you thousands of dollars. If the surface is cosmetically flawed across the entire area, concrete resurfacing can provide a brand-new decorative look over the existing slab. However, if more than 30% of the surface is severely broken, heaved by tree roots, or structurally detached, full replacement is the only lasting remedy.

Our Step-by-Step Concrete Repair Workflow
- Thorough Damage Assessment: We inspect the slab, check for subgrade voids, and identify underlying moisture causes.
- Mechanical Surface Preparation: We chase cracks with diamond blades, grind away spalled concrete, and pressure-wash the area.
- Polymer Injection & Patching: We apply industrial bonding agents and place high-strength repair mortars.
- Waterproof Joint Caulking: We seal expansion and control joints with UV-stable commercial polyurethane caulk.
- Walkthrough & Maintenance Review: We review the completed repair with you and offer guidance on ongoing care.
Frequently Asked Questions
Can you guarantee that repaired cracks will never return?
While our flexible sealants bond permanently and keep water out, ongoing soil settlement beneath an unstable slab can cause new stresses. Addressing underlying drainage and grading is essential to preventing future movement.
How quickly can I walk on repaired concrete?
Most rapid-set polymer mortars and polyurea joint sealants cure rapidly, allowing light foot traffic within 2 to 4 hours of completion.
