All-
I have a steep, downwardly-sloped driveway made of concrete. Its developed a crack right in the center of it from the top all the way to the bottom.
I’d ideally like to seal it with some kind of product. I know I can Google this but I am interested to see if anyone on here has specific experiences with certain products that have done a bang-up job in sealing their cracks and hopefully preventing further expansion.
So…what’s the Dope on concrete crack sealants?
I used PL brand Polyurethane Concrete Crack and Masonry Sealant. On a horizontal surface with some foot traffic it lasted 8 years before I took it out and traied patching cement. The patching cement appears to be too quick drying and it cracked. after a week.
I also used the sealant to seal cracks in a concrete stairway and the seal hos bo=een it place for over 8 years with no problem. It provides a flexible gasket like seal which should withstand gradual expansion of the crack, and if not, you can easily peel it off and re-seal.
Someone with experience using concrete patching cement on a steep slope may give you advice on patching cement.
Color matching may be a problem.
Good luck
Thanks! I’m not overly concerned about color-matching but you raise a valid point: is the degree of slope a concern in as far as what kind of product I should use?
The degree of slope is not an issue with urethane type sealants as they are flexible when they dry. Concrete will possibly sag, but again I have not tried concrete patching a steep slope.
I told you in your last thread on this, use a two-part epoxy sealant.
They are usually two tubes that extrude into one nozzle and available at any decent hardware store.
Are you going to properly clean and repair the driveway as I suggested, or just slap a patch on it?
