Repair Cracked Concrete Slab

I'm hoping I can repair a significant crack in my uncovered patio using the same technique. My 10x30 patio wraps around the house into the carport so its hard to find a place to stop to consider a repour. The crack cuts across an outside corner making a triangle about 10x4 which luckily does not touch the house. The crack is up to one inch wide. More troubling is an up to one inch difference in level from side of the crack to the other. Atlanta has a lot of clay in the soil so that may be an issue I need to explore. CA

Have a 2 week old 16 x 37 slab which started cracking while the contractor was floating the concrete. It has continued to crack in several differant locations throughout the slab. Control joints were cut the day after pour but the cracks keep moving over the joints. How, if any, can he contractor repair these cracks. Any suggestions on a possible permanent repair.

I have a new driveway (just over 2 months old). Last week I had a new roof installed. The roofers covered the driveway with plywood to prevent damage from their very large and heavy truck but as they removed the plywood I noticed six new hairline cracks, each about 6-8 feet long. How do I prevent these cracks from growing, and is it a good idea to put a concrete sealant on my driveway? By the way, the driveway has a brick border with brick strips every 8 feet. (The bricks were not damaged by the truck).

It seems that I have two problems that I would like to know if they can be solved in combination. I have 1/4-1/2 inch cracks in my patio as well as some low spots which may be due to some settling. There are no new cracks so I'm ready to repair the existing cracks and resurface. Can I repair the cracks with an epoxy and then use a more substantial concrete overlay that will help with the low spots?

28 days ago we had 2 new colored driveways poured with stamped edges and several stamps done horizontally. We have not driven on them & the contractor is supposed to be sealing them very soon. We have multiple cracks, and we are wondering what we should expect from the contractor and/or what we can do to minimize any further problems.

I have a concrete walkway in front of my house that required a catch basin for a sump pump. Unfortunately, the contractor failed to install the proper cover at the time he fabricated the catch basin so he came up with his own solution. He cut out a 1" deep by 1" wide lip along the top of the opening of the catch basin. This fits a 19" by 19" frame that will hold a 16" by 16" grill. Unfortunately, about 1/2" of the inside perimiter of the 19" frame extends over the opening of the catch basin so the frame is not entirely supported by the cut out lip.

The frame and grill weigh about 50 lb and is not in a location with heavy foot traffic at all. The concrete slab is about 2 1/2" to 3" thick so there is plenty of concrete underneath the frame even after the cut out. The most weight it would need to support is me, but it will get plenty of moisture.

My question is, will I have any problems with the concrete lip that was cut out over time due to the frame only partially being supported by the lip? Would the concrete perform better if the grill was entirely supported or does it make a difference?

thanks for your help.

My new driveway immediately as it dried revealed two narrow drying cracks several feet in length. The contractor immediately resealed the driveway and cut larger grooves. However the cracks are unsightly, on the walkway to the house, and I am unhappy. I filed a complaint, and have been offered an epoxy resin to be added, but my impression is that still leaves me with the cracks that detract visually. What are my options? Is it unreasonable to want some level of refund on this product? Should I have the expoxy done or will this add to the unsightliness? Was this preventable? We did have steel rebar as part of our installation. Any insight is appreciated.

We have a 40 year old slab that seems to slide when the soil is dry. It moves up to .75 in.
We soaked the dry side of the house (the side that slides) for awhile. We stopped because we didn't see much in the way of results. However, since we have stopped soaking the soil the sliding has started again. I want to pour cement under my 16-in. slab sides, but I think I should soak the soil and move things together a bit before I start digging. What do you think?
