(Video) How To Repair Concrete Spalling

Spalling concrete is concrete that has chipped, flaked, broken off or has dents in it... This is usually the result of poor installation and poor mix of the concrete, causing it to become weak and possibly damaged.

 

First, clean the concrete with Shell Busey's Home Cleaning Formula and rinse well.  While still damp from washing, apply a concrete adhesive (Weldbond) to the entire area.  Mix the Bonded Topping mix to a thicker consistency (like a muffin mix) and trowel over the prepared area.  Texture the surface with a broom if that look is desired.  Allow to cure for 24 hours, then follow with the brightening concrete procedure.  Leave for the one week and seal with a solvent-based concrete sealer.

 

For Severely damaged surfaces, I would suggest hiring a Concrete Restoration service to place a new layer of concrete minimum of 1.5" over the existing surface.  If concrete is sinking in some areas I recommend using a Slab Jacking service to lift and stabilize the slab.  Avante Concrete can handle your slab jacking needs.
