Portland Oregon concrete contractors
As hard-wearing as concrete is, repairs are inevitable. Whether they are a large or small repair, we will be able to resolve them for you promptly.
The first thing we will need to ascertain is what caused the damage. Sometimes this is obvious; something like a vehicle driving into a concrete pillar does not need much detective work. But other times, there can be underlying issues that can lead to concrete repair work being necessary. Cracks in concrete are a perfect example of this, and we would need to accurately assess the project to make an informed decision about what caused them to make sure that we get to the root cause and can be confident that the repairs we carry out will fix the issue once and for all.
What is best to patch concrete?
A variety of options are available for repairing damaged concrete. One option is surface grinding followed by slurry sealing with an epoxy resin sealer. This process removes all traces of oil from hardened surfaces like cracks in non-reinforced areas while also filling low spots before being coated repeatedly with multiple layers to provide strength and durability against future weathering effects such as freeze/thaw cycles and high traffic volumes.
How do you repair cracks in structural concrete?
Concrete is a sturdy building material; yet, it can still crack. Cracks in concrete are unsightly and cause structural problems due to water seepage that causes corrosion of steel bars or rebar found inside the cracks. The best way to repair cracked structural concrete involves removing all loose particles from the area surrounding the hole then inserting an expandable metal mesh into gaps deeper than 3/8 inch with pneumatic drills until they reach tight against each other. To finish off this process, you must seal any openings around these areas by using polyurethane foam injected through holes drilled on either side of where the new epoxy resin will be placed not to allow air pockets that would form gas bubbles curing resulting in weakened structures.
The cured resin is placed in the concrete crack with two small holes at either side, and filler is added to fill any gaps for deeper cracks. The filler used has a resin content of 92% to achieve the most consistent results. The new epoxy resin is mixed with hardener at a ratio of 1:1 to form a rigid silicone; after mixing the resin is poured into the crack and any filler added. Polyurethane foam is then placed into the opening on each side to make sure there are no air bubbles that would weaken the structure. The new epoxy resin is stiffer than concrete and can fight off water penetration.
After the epoxy hardens, sanding will be added to the epoxy’s surface to smooth it off and make it look uniform. After a sander has smoothed off the surface, clean water is sprayed onto the area to ensure the surface is free of dust and debris before being sealed up.
How do you fix hairline cracks in concrete?
It’s often difficult to pinpoint the cause of hairline cracks in concrete if they’re not visible. However, you can fix these breaks by using a polymer-modified filler material to seal them up and make it so water cannot seep through any further. Other methods, such as pressure washing or fixing with acrylic or epoxy resin, are typically considered the most effective way for longevity.
