[@aaronwilson9763]

QUESTION: if having to replace an entire section (because of excessive damage) along a run of sidewalk...do you need an "expansion strip"?

[@JathTech]

no. You only need an expansion strip when butting up against an existing structure like a house foundation that won't move with expansion. the other sidewalk sections have expansion joints (cuts or grooves) in them already so they should be able to absorb any movement of small pads like this one. If you're going over around 8 feet, you'll want to add expansion joints that line up with existing joints. You can do this with a jointing trowel or an edger, or you can cut the joints with a concrete or diamond blade saw after 24 hours. You'll want the joint to penetrate at least 25% through the slab, which is a 1 inch depth in a 4 inch slab.

What do you do for the curb on a driveway that is rounded? I have a small section like in your sidewalk repair (Not replacement) but I drive over it to get onto the driveway and it is curved.

Thank you for this video - very similar to my issue. How much might it cost (materials and labor) to have this done for me?

[@BlakeShaddix]

Depends on size of driveway and your location plus if you need trees and roots removed. Probably 5-10 thousand for entire driveway. Patches much, much less. Getting the roots out that caused the cracks in the first place has to be done.

[@alexthesalvo]

I have self leveling concrete I need to use on uneven parts of my concrete slab

[@infraprods]

Just a precaution, most self leveling compounds are meant for indoor use and to be covered with flooring. Traditional self leveling probably won't hold up in outdoor use when it's uncovered.

[@gazinta]

Follow the instructions on the bucket. It will be runny.

[@venomsixxx]

How. to. repair. cracks on stencil concrete. driveway?

[@zoilapena7708]

To cover those small cracks or thinner cracks you use the cement with rocks or plain cement please

[@EvilBontaKun1]

This might be 2 years too late but Cement is a part of Concrete, it's the binder. So if you need to cement something, you're just using the cement. Pouring concrete adds rocks as aggregate along with cement and some sand and is usually used like in the instances where he was pouring sections like the sidewalk. I hope that helps.

[@RikoLime]

HUh gonna have to watch more... find the right one.. HOA had my driveway pressure washed because it was "too dark" and claimed it didnt look new enough. Now I have to use outdoor cleaner and have it pressure washed again twice a year because it literally turns black every few months - only ever since they first cleaned it. It sucks!

[@followjesus5729]

Not sure if this would help, but I believe that there is a sealer use. And should be applied after a power wash.

It depends, is your walkway already heated or has a hydronic system preinstalled? If not, we do recommend a quick setting cement for its superior bonding properties.

[@jas20per]

Purchasing Concrete!!? Make your own using the magic numbers 3:2:1 by volume, doing it this way you can choose the correct size Aggregate for your purpose. So lets go three parts aggregate you choose the size. Two parts Grit Sand sometimes called Concreating sand or sharp sand. One part ordinary Portland Cement or fast setting version. Now the bonding agent usually this is Builders PVA Adhesive or for a stronger bond and also to add some flexibility to the mix use SBR additive replacing the PVA. Doing it this way makes things far cheaper you will always have the exact amount of concrete for your needs, and as long as you keep the Cement in a dry place you can have concrete or brick mortar whenever you want it.

Let the concrete cure (hardend) then remove your form should be easy by then

[@kiloindiaalphasierra4298]

you can add an oil type base to the boards so they pop off when the concrete hardens. sort of like PAM cooking spray is used in pans

[@merylburke9137]

That doesn't look remotely easy to me. But for some people it's doable. At least what it does is make me aware of what I would expect a repair person to do if I hired them to level out the dip in my cement driveway.

Is there a leveling compound i can use that will yield a more finished feel and look? can i pour concrete over the top? any tips would be greatly appreciated. #rookiemistake

[@djratino]

Use a diamond surface grinder. 4 1/2" right-angle grinder with the threaded diamond cup wheel. They're hell to get off once grinding. I propped a lawnmower blade in my wheel to get it back off the grinder. Rather than repour a slab for a driveway, I once used that to cut the edge down for a slope. Note, they make a 7" version too for larger grinders.
