Concrete Replacement in Sunnyside, Queens

When Does Concrete in Sunnyside Need Replacing Instead of Patching?

Replace concrete when cracks run through the slab, the surface has sunk or heaved, or the top is flaking apart. Patches hold on small chips. They fail when the base underneath has moved, because the new material sits on the same weak ground.

Sunnyside has many older buildings, and their concrete has been through decades of winters. Walks that lead to entrances, paved areas beside apartment buildings and slabs behind attached homes all reach the end of their life eventually.

Tree roots add to the damage on residential blocks, where mature trees push up paving close to a house. A slab lifted by roots will not settle back down, so it needs to come out.

If you see water pooling against a wall, the slab may have shifted toward the building. That is a sign to replace the slab with the right pitch, not to add another coat on top.

How Is New Concrete Poured So It Lasts?

Lasting concrete depends on what is under it. We remove the old slab, dig out soft soil, compact a gravel base, set forms to the correct slope and pour. The surface is finished and left to cure before anyone walks on it.

The slope is the detail that people notice later. A slab that sheds water toward the street or a drain stays drier and freezes less. A slab that holds water cracks and scales within a few winters.

We also cut control joints so the concrete cracks along planned lines, not across the middle of a panel. A broom finish gives grip when the surface is wet or icy.

What if the concrete touches the public sidewalk?

Concrete on the public sidewalk is a different job. It generally needs a DOT permit, and the owner must keep it in good repair under Admin Code 19-152. Read about sidewalk violations to see how notices work. Confirm current rules with the city.
