How to repair badly poured concrete?

Question

i am a decent diy guy at my own house, but my friend, who is blind, needs help with his own house. mostly stuff i can do easily, like drywall and fence issues, but he needs help with concrete- he has a steel frame with poured concrete floors entrance stairwell and small porch, like five by four, and it's crumbling away, the surface is disintegrating. no cracks, but falling apart. doesn't much matter what it looks like, but what can i do to preserve the present structure as long as possible? it was only laid three years ago and now he's tracking concrete into his house! thanks!

Answer 1

They have a concrete grinder thats used to grind concrete after it was poured. For if it rained or if a form busted out in a tie beam and it grinds cement to a finish. you can get one at a rent supply. Its a dirty job you will have to grind all the bad concrete away and seal it.

Answer 2

Go to Home Depot, ask for the "filler and surface" for concrete repair, it shouldn't take much more then a small from for this. Make sure you have all the loose stuff off and cleaned, wet it some before pouring.

Answer 3

sounds like the concrete froze before it dried--when it was poured--the slabs are probably only bout 2 or 3 inches thick--and they did nt put any reinforcement in them..so the best thing to do -is to break them out and repour them--you dont have to do all of them at one time-- be sure to put a light broom finish --going long wise of the step--you can use sack crete  to repour them---grinding wont help-- because the concrete comes to the top of the metal  frame--so any grinding will cause a low place on each step---and will hold water--which will cause more flaking of the concrete,,no sealer is needed because this will cause the steps to be slippery when wet
