Cracks in basement Floor

clagaApril 4, 2012


I have 2 or 3 cracks in my basement floor starting where the drain pipes enter the floor.

The largest width of the cracks is approximately 1/8" to less than 1/4"; the cracks diminish in width over the 5 to 7 foot length of the cracks.

Can they be chauked? If so is there a special chauk for this application?

If the concrete is dry, JB Weld in the cracks followed after full curing by sanding with a pad or or random orbital sander with 120 grit might make the cracks nearly invisible. Sand just to cut the cured epoxy flush with the concrete. The concrete will ruin the abrasive paper quickly so several pieces may be necessary. If the cured epoxy is overheated, the surface will not be smooth. Sand a little and let it cool. JB Weld is expensive but is a good product. Use the slow curing, dark colored which is usually the product in the larger tubes.
