Any advice on patching a cement driveway?

Question

Our cement driveway has really taken a beating. It has large cracks and it is pitted from salt dripping off of the car in the winter. I've used the rubbery liquid stuff in the cracks and it shrinks and looks worse than ever. Can I do a skim coat of cement over the whole thing? We can't afford to replace it right now.

Answer 1

Yikes! No matter how tempting, stay away from the skim-coat of concrete idea. Unless you lay down a good four inches, it will crack up like peanut brittle.

I resurfaced a concrete deck over a garage that had cracks everywhere and was leaking. The job had to be perfect, so I did a huge amount of research, and found a urethane-based product line that worked great. The job was in Florida, so I had a lot of expansion and contraction, and the material had to be flexible enough to move, and hard enough to make a good deck. The products met these requirements, and more.

There is a rubber compound you mix up and apply to pits and cracks, and a urethane coating that is rolled on for a finish. It is a bit slick, so you will need to add an abrasive in the mix for skid-proofing.

The name of the product is Sanitred @ www.sanitred.com. They ship in about three days after your on-line order and are very helpful.

Good luck on your project!

Now this all depends on if you are talking about a pitted kind of thing or holes... not sure how deep but up to about 1 - 3 inches deep I've patched some areas in my concrete parking space and sidewalks, Two things seemed to help, because I actually had to do it twice, the second time I got some advice at the store, clear out as much as possible of the loose gravel and really knock the parts loose, then spread a coat of a glue product that bonds the old concrete with the new concrete, Mix the concrete according to bag directions and use a piece of wood like a 2x4 to level it off.

Answer 3

The Home Depot has a kind of cement called "leveler" , the bag of this product is about $35, just read the mixing instructions, mix and then pour on the cracks, it will level by itself, you do not need any tools to straighten the surface,

Answer 4

the only REAL solution is replacement. I think you should wiat and save the money. Quick fix never work well and ocst more in the long run. A skim coat over the top is too thin and will crack.

Answer 5

it relies upon on the product used and approach of application. some forms of concrete treatment speedy and a few sluggish. for a proprietor of a house wait atleast 24 hours it ought to have a compression capability of 3000psi after 30 days of curing. as far as cracking all concrete will crack. Its a competent theory to have strengthen joints each ten ft. you would be fantastic

Answer 6

Go to Home Depot or Lowes. There are materials that will do the job. Just ask the salesman for some help.
