Bricks, Masonry, Asphalt and Concrete - Filling in Exansion Joints

What is a good product to use for filling in the joints I cut into the concrete? I cut them about 1/4" wide x 1" deep.

I found a few products but they all say the joints shouldn't be more than 1/4" - 1/2" deep. I would need to fill them with sand or expanding foam first.

Is there something that is self leveling that can handle deep joints?

Thanks!

There is a butyl rubber caulk that works great in expansion joints. I wouldn't worry too much about the depth, as it will just take more of it to fill. It levels out quite well and looks fine. Sorry I don't have the brand name, but look for butyl rubber. Regular caulk or silicone won't work.

I'm with chandler, just don't worry about the depth. A deeper cut will just ensure that any cracking occurs where you cut the grooves. The caulking has to stand up in rain/snow and sun conditions without sticking to your feet, etc. when it heats up.

The standard way is to use a backer rod (round closed cell foam) available at a big box.

Force the correct size into the joint and leave it about 1/4" or so below the level of the concrete. This will allow you force the caulk into the joint and make it adhere wel to both sides. Smooth the joint when it is filled.

1/4" Joint is not really suitable for an exterior joint. If it were me, I would not fill the joint for one full climatical cycle (9 months to a year). At that point, the size of the joint will have stabilized, and you should be OK sealing the joint.

Go to a masonry store and look for backer rod (if you want to use it) primer and a Urethane sealant. Two companies that make it are Sonneborn and Sika, there may be others in your area.They make it for homeowners caulk guns, a larger caulk gun and a bulk sausage gun. It comes in a selection of colors.After puttin the caulk in you have to tool it.They have knives at the masonry storeor you can use a plastic spoon. There are two types in the one kind I get at work. Sonneborn NP-1 or SL-1 ( self leveling) but you still need to tool both. Hope this helps you out. Good Luck.

Oh by the way, I only caulk my expansion joints and my cuts that I put in the concrete are probably 1/8 x 1" deep are only relief cuts to make the concrete crack in those areas. Just for info.

I am pouring a concrete reatianing wall. i do not want to use wood as an expansion joint due to mosture. The annual temps are between 45 - 75 F. What can i put in as part of the pour ? Thx.
