Concrete Repair & Replacement

When to Repair vs Replace Concrete

Deciding whether to repair or replace damaged concrete depends on the severity of the problem. Minor surface cracks, small chips, and cosmetic blemishes can usually be repaired cost-effectively. If the damage is limited to the surface and the underlying structure is still sound, repair is often the best choice. We can fill cracks, resurface worn areas, and restore the appearance of your concrete without the expense of full replacement.

However, when concrete has severe cracking, sinking, heaving, or structural failure, replacement is usually the better option. Large cracks that run all the way through the slab, sections that have settled significantly, or areas with extensive damage from freeze-thaw cycles typically need to be removed and replaced. Trying to patch these problems is like putting a bandage on a broken bone. It might hide the issue temporarily, but the underlying problem remains.

We provide honest assessments of your concrete and recommend the most practical solution. If your driveway or patio can be saved with repair, we will tell you that. If replacement is necessary to ensure safety and long-term performance, we explain why and provide a clear estimate. Our goal is to help you make an informed decision that protects your investment and meets your needs.

Common Concrete Problems We Fix

Cracks and Spalling

Cracks are the most common concrete problem. Hairline cracks are normal and usually do not affect the structural integrity of the slab. However, wider cracks can allow water to penetrate, leading to further damage, especially during freeze-thaw cycles. We repair cracks by cleaning them out, filling them with specialized concrete repair compounds, and sealing the surface to prevent future water intrusion.

Spalling is when the surface of the concrete flakes or chips away, exposing the aggregate underneath. This happens when water gets into the concrete and freezes, causing the surface to pop off. Spalling not only looks bad but also weakens the surface and creates trip hazards. We remove the damaged material, clean the area thoroughly, and apply a new layer of concrete or resurfacing compound to restore the smooth, durable finish.

Settling and Sinking

When sections of your concrete settle or sink, it creates uneven surfaces and trip hazards. This happens when the soil underneath the concrete compacts, washes away, or shifts. Settling is common in driveways, sidewalks, and patios, especially if the original base was not properly prepared. We offer concrete leveling services to lift and stabilize sunken slabs without the need for complete replacement.

For areas that have settled too much or where leveling is not practical, we remove the damaged section and pour a new slab with proper base preparation. This ensures the new concrete will not settle again and gives you a smooth, level surface that lasts for decades.

Discoloration and Staining

Concrete can become discolored from oil stains, rust, mold, mildew, and other contaminants. While some stains are purely cosmetic, they can make your property look neglected. We offer cleaning and sealing services to remove stains and restore the appearance of your concrete. In cases where staining is severe or the surface is badly worn, we can apply a decorative overlay or resurfacing treatment to give your concrete a fresh, new look without full replacement.

Our Repair and Replacement Process

When you contact NWC Norwich Concrete for concrete repair or replacement, we start with a thorough inspection of the damaged area. We assess the extent of the damage, determine the underlying cause, and recommend the best course of action. Here is what you can expect:

• Free on-site evaluation and detailed estimate for repair or replacement
• Explanation of the problem and why it occurred
• Clear recommendations for the most cost-effective solution
• Professional execution using quality materials and proven techniques
• Proper surface preparation and reinforcement to prevent future issues
• Clean, efficient work with minimal disruption to your daily routine
• Complete cleanup and disposal of old concrete if replacement is needed

For repair jobs, we carefully prepare the damaged area, remove any loose or deteriorated material, and apply the appropriate repair product. We match the color and texture as closely as possible so the repair blends seamlessly with the existing concrete. After the repair cures, we seal the area to protect it from future damage.

For replacement projects, we remove the old concrete, properly prepare the base, install reinforcement, and pour new concrete to the correct thickness and specifications. We take care to match the finish and appearance of your existing surfaces so the new section looks like it has always been there. The result is a durable, attractive repair or replacement that restores the function and appearance of your concrete.
