Foundation Patch: Hydrolic Cement??


this is a sealant, NOT a structural part of pavement,,, to be certain the sealant can be supported, however, fill to appropriate depth w/CLEAN sand,,, read the previous suggestion,,, you do NOT want 3sided adhesion - ONLY both sides, NOT the bottom,,, there isn't any sealant designed for 3way.

Since the dirt has washed out where the water drainage was, dies this sealer have enough density to sit in the crack/hole (not too big per photos) and cure?

the sealant's NOT structural,,, if you use a non-sag & either fill the jnt as noted above OR install backer rod ( preferably closed cell ) of the appropriate dimension, won't make any difference to the sealant.

EDIT PREVIOUS POST,,, think i said sand,,, meant vermiculite,,, vermiculite's compressible, sand ain't !

Sorry I wasn't clear.

What should I rip out? All the concrete or all the patch that is crumbling?

tx,

I would rip the hole thing out. When you said the soil was washed out from under the concrete, made me think if this was the right thing to do.
is this your responsibility or the towns? being the garbage truck uses it.

THe alley butts up against my slabs along side my foundation. Those slabs are just under 2 ft and are at a slight downward angle as in the photos.

I went to our local box store and found 2 different items:

1. Was a polyurethene tube concrete sealer/patch by Water-tite.

2. An Epoxy concrete sealer/patch for sealing concrete cracks which you mix by Rost-o-leum.

Both products said to use a Degreaser before applying. (recommendations?)

Does either one have an advantage or disadvantage? The epoxy costs less than the tube stuff.

The tube is about $3.50 for 10.5 oz.

The epoxy which you mix is about $17. and will do 14 lin feet.

THanks,

Tom

In some of your pictures it looks like asphalt. You cant use uratheane on asphalt, it just wont hold. I own a waterproofing company and i'll tell you want i think should be done. First get rid of all the cement you put down, that wont work, it's got to be able to move and still hold. Second is go get a wire brush and duct tape it to a broom stick or something so you can stand up and brush the hell out of all the cracks. Third, blow all the areas with a leaf blower or broom it very good. Fourth, Any place where the crack is concrete to concrete use a TOOL GRADE uratheane not a pour grade. A pour grade will look like crap and it will be a mess plus you'll never get it sealed. They sell SIKA in uratheane tubes at homedepot. Just shoot it and tool it so its seald with something like the rounded end of a butter knife. Fifth, any where the crack is asphalt to concrete or asphalt to anything you must use an asphalt based product. the chemicals in asphalt eat urathane products. Try to find a mastic in tubes or an asphalt crack filler.

Hope this helped.

Is the polyurethane in the tube the right stuff?

Also, would the epoxy work?

THanks,

Tom

Epoxy is too Brittle and hard. It will not be flexible to be able to expand and contract.

Not an application for a patch job.

you can chase pennies and go through the same thing next year. If you enjoy that and do not have anything better to do, you can patch with good flexible materials, since you have an unstable material with poor support under it.

Would you use this water stop cement on cracked driveways also, or self leveling driveway caulk?
