a) We have a rubble foundation that was leaking badly in any sort of rainstorm. Perez hand dug trenches around the home and below the original footer, poured new footers and installed cider blocks against the existing foundations, applied a waterproof membrane to prevent leakage. Filled in the trenches and left the area clean as it was before he started. b)Ripped up old driveway and rebar by hand. Leveled off the base of the driveway so that drainage was away from the house. Installed new cement so that the driveway is now new and smooth. Looks great. c) We have 4 stone porch support columns. The one on the driveway was leaning away from the house due to the condition of the now replaced driveway. This was pulling away from the home. Perez dismantled the old column, stone by stone, poured a new and level footing and reused the existing stones to match the remaining columns and is now perfectly level. Excellent work all professionally done. All debris was removed timely and the landscape was returned to original condition. I highly recommend Perez and his team for any concrete work. Very satisfied.
