Concrete Repair Product Reviews Concrete surfaces are constantly under attack bythe elements resulting in the need for repairs. When I was in college I had a job doing maintenance in a downtown Denver hotel. I didn't really know what I was doing but most things weren't that hard to figure out. One time, though, I needed to repair a broken up concrete door threshold. I removed the old concrete and went down to the hardware store and bought a bag of premixed concrete. I added the amount of water the bag said to use (maybe just a little extra for good luck) and poured it in and troweled it off-another job well done!

Two weeks later my boss called me into his office. Seems he had just gone past my repair work and found it as cracked up as the original threshold. I was so disappointed! We went back to the scene of the crime to do some actual investigation in advance of launching off on another repair attempt. While we were standing there, one of the kitchen workers came through with a heavy hard-wheeled dolly loaded with supplies that dropped onto the threshold as he passed: we knew the cause of the problem. For the next repair, we added reinforcing steel, used higher strength concrete, and eliminated the drop-off onto the threshold. When I left a year later, the new threshold was still working well. I took away a good lesson-one that I soon found applied to just about any repair work.

Door sills may be constructed of wood or metal and are generally fitted above a concrete foundation. Over time, foot traffic and weather elements may weaken and corrode the concrete to the point it begins to crack and break up. If this happens, a gap may appear between the concrete and the sill. The old concrete must be removed and replaced to close the gap. Put on eye protection, along with work gloves and a dust mask. Use a chipping hammer with a chisel bit to break up the concrete under the exterior door sill then pull out the rubble by hand.

Vacuum out any remaining pieces with a shop vac for a clean surface.

Wet the cement/sand mixture with a garden hose lightly then mix it again until it becomes the consistency of mud.

Immediately, tilt the wheelbarrow up, allowing the concrete to pour down onto the bonding agent before it dries.
