Concrete Repair Made Easy: Common Issues and Solutions

While concrete is strong and durable, it is susceptible to damage over time. Top concrete waterproofing service in Rive-Sud providers can fix a variety of common concrete problems using proven methods. Cracks, spalling, erosion, and leaks are all repairable issues. This article covers the most typical concrete repair needs and effective solutions. 

Repairing Cracks 

Cracks are the most common concrete damage. Very fine cracks can simply be sealed with a penetrant sealer. Wider cracks need structural repairs: 

●       Epoxy Injection - Epoxy is injected under pressure to penetrate cracks and structurally rebond the concrete. 

●       Stitching - Steel bars are epoxied into holes drilled across the crack to stitch it closed. 

●       Rout and Seal - The crack is routed into a wider V-shape and filled with an elastomeric sealant. 

Patching Spalling 

When concrete spalls, flakes, or chips off, it exposes the underlying rebar to corrosion. Spalled areas should be patched: 

●       Saw cut a clean edge around the spall, then chip out all loose concrete.

●       Coat exposed rebar with a bonding agent and anti-corrosion coating.

●       Fill the cavity with a patching mortar blend. Finish and cure the patch properly. 

Resurfacing Erosion 

Surface erosion causes scaling, pitting, and dished areas. Thin resurfacing restores a smooth appearance: 

●       Diamond grind or abrasive blast to remove all unsound concrete and provide a rough profile.

●       Apply a bonding agent slurry layer before pouring a thin resurfacing mix.

●       Finish the surface to match the surrounding concrete. Allow proper cure time. 

Waterproofing Leaks 

Persistent leaks and moisture migration require sealing concrete with waterproof membranes or hydrophilic chemicals: 

●       Surface-applied membranes are commonly used for above-grade applications by the leading concrete waterproofing service in Rive-Sud.

●       Interior-injected polyurethane foams or hydrogels can plug leaks inside slabs on grade. 

When to Call a Professional 

Some concrete issues, like minor cosmetic damage, can be addressed with basic DIY repairs. However, extensive repairs to structural elements or repairs needed to stop leaks should be handled by concrete repair professionals. They have the specialized tools, materials, and expertise to diagnose problems and make lasting repairs. 

Hiring Qualified Contractors 

Not all contractors have the specialized expertise required for structural concrete repairs. Property owners should seek experienced concrete repair contractors who are fully insured and licensed. Reputable contractors will provide proper documentation and references illustrating their qualifications for completing complex concrete repairs. 

With the right products and methods, an expert concrete repair service in Rive-Sud can fix common issues like cracking, spalling, pitting, and water leaks in order to extend the life of existing concrete structures. Proper repairs restore both visual appeal and structural integrity.
