Concrete Repair Specialist repairing, cutting, grinding, removal and concrete repairs commercial and residential concrete contractor. Hi I’m James Belville 3rd generation in the concrete industry, I have fixed, poured, cut, removed and replace a lot of concrete in the past 30 years.
Concrete is a very versatile building material.
It amazes me every day of the many different ways you are able to create a beautiful piece of art work out of old concrete, by simply repairing it from a rustic look. Here is a technique have done in many homes. Inside of a lot of homes these days, contractors pour the floor throughout the entire home. They later choose to apply flooring materials such as carpet, vinyl, wood ECT… Often homeowners don’t realize is that their walking on a concrete floor that has potential to be an absolutely beautiful floor, better than any other flooring material. It’s the hardest and the most durable and if taken the time the cleanest. Sometimes we think of a concrete floor as a cold floor, it’s a very consistent floor. When it’s really hot outside the concrete floor will stay cool and on cold days it feels warm.
Concretenever stops getting hard and it is forever expanding and contracting. Because it does this it will crack. Interior floorslike to do this more often as the slab is held in place by walls. When the slab warms it expands, creates pressure and POW! You have a crack. Ok think of what marble looks like… It has veins running throughout, light colors and dark colors. With some mild repair works and some interesting techniques your old rustic floor can be transformed it to a stunning high end high gloss concrete floor.
I would want to prep the entire floor starting with the cracked areas; they have to be cleaned and free from dust and rubble. Then filled with a cement patch compound as this will be a permanent repair for large cracks. Hair line cracking is essential to increase the beauty when the repairwork is complete and the job is done. Once the cracks have been addressed and the patch work has cured the next phase starts, here the floor has to be clean, free from glues or anything stuck on and oils have to be treated. Sanding the floor can be a very time consuming way to prep the floor, I found by using a large grinder you’re able to prep floor faster and more efficiently plus your closer to the slab and can see things that couldn’t be seen with floor sanders and such. The color variations will later add to the end result as well, so now the floor is in the next phase, do you add color stain? Not necessary unless you as the home owner would like a theme to match something inside your house or just like to have a color. After thinking about it for a while you decide to keep it natural, my favorite, less money out of your pocket and a nice dark grey high gloss floor will match virtually anything.
The floor repair is in its finial preparation stage, if possible its best to perform the next task when the concrete floor is above 60 degrees. This is the time to add any extra veins throughout and if there is a room that was chosen for another color or design such as streaks of accent colors like gold, silver, black or nothing at all, personal preference is a very helpful tool for your concrete repairman. I’ve had someone once who wanted their daughters name in her room and I thought how fun is that! So of course I said yes I can do that for her…
Ok we come to the final stage of the repair, polish or wax work very good. Some are made of a chemical compound, some are bio-degradable and then there is paraffin type wax, this is the one I prefer indoor when the home is intact with families that reside in that home, new builds I prefer chemical sealant but it’s very strong and the smell will linger for a very long time. The paraffin wax has to be worked in with the use of a floor buffer. This tool is heavy and it spins at a moderate speed to heat the wax and as it melts and works itself into the pours of the floor it becomes thinner and thinner, as its being warmed and spun it begins to shine and become glossier to the point of reflection. Completing this procedure throughout the home there is no smell from this type of application. The wax basically burns on to the slab. One of the most difficult things is to remove wax from concrete, nearly impossible aside from grinding or sanding. So it is very durable and only sweep and mop it. Routine polishing is something a homeowner can do by renting a very small floor polisher once in a while and bring back the fine luster quickly and easily.
Patios and how they need to be repaired
In this part of the country families spend most of their time outside enjoying the beautiful weather. A lot of that activity is in their very own back yards, they have patios, pools and pool decks maybe a small sport court. Just like the concrete everywhere in the world it to will have things come up and it might not be anything other than a extension. If your one of the lucky ones here in the south west you have a lawn as well. With a lawn there will be lots of watering, with all the water that may stream a crossed your concrete it then could start to cause the ground (sub-grade) to weakening and the concrete will begin to shift and move. If there is substantial weight in it, say like the columns that hold the roof up over your back patio. Failure on a back patio can be just repaired, depending on the project of course and how long it’s been putting stress on the house and the structure. These generally are difficult and a bit time consuming but a lot less expensive than a full removal of the old concrete and then jack up roof to plumb and so on. I’m going to talk about a repair that as little as a third of the price and just as good if not better, what am I saying it IS better!
If the slab is mostly in tack and its only broke by the columns then this cosmetically will look best, if the crack goes into the slab closer to the center then when the bad concrete get saw cut and removed then the “cut” line will have to move closer to the end of the crack. Once you have established visually a proper cut line it then can be cut, carefully not to cut to deep to fast, letting the machine do the work for you at its pace, after all that’s what they design the machine to do.
It is cut. Now the columns have their own footing and that is also a concern as they will continue to do this and will eventually break the new slab too. So before the section that was just cut is removed, it can be used for a great floor to use the heavy duty jack system to brace the house up. However the safest way to put that jacks is a priority as it can create massive structure damage if not performed flawlessly. Once the jacks are in place you then begin to raising process. This is the tenderest things you can do as the walls and ceiling that on the exterior could crack or if already cracked could have chucks and pieces fall off. This is a possibility any ways but in experience is key here. The home is jacked to a high enough spot that rebar can be added and the dirt removed from around the footing of the columns. Once a larger hole that is tapered to get wider at base (a true footer) and rebar is in place you can pour high strength concrete onto the hole especially designed for a column footing.
Meanwhile busting up concrete is something no one can say they like it but it has to be done for the recycling process. Jack hammer is better than sledge hammer but whatever it takes to remove it has to be done. You can “demo” all but the couple spots you’ve chosen for the jacks and the braces for the roof. Remove all debris and dowel in rebar stubs along the face of the existing patio slab 18 to 24 inches apart. This will insure the new concrete will remain at the original level it was poured
48 to 72 hours have to go by for the high strength concrete to completely cure. Once cured, the jacks can be lowered from the roof and columns, take the rest of the rubble out and at this point add a sub-grade compaction material suck as crushed rock that’s 5/8 minus as it tightens and locks itself with more compaction. Once finished you then can pour the concrete and if need be color match and or finish it with standard type. Once it is poured in place it will need a very good quality sealant in the joints such as polyurethane and a overall spray on sealer. Both of these will help in the protection from the same thing happening twice.
