Concrete Repair in Clementon, Cherry Hill, & Washington Township, NJ

After 25 years working concrete in South Jersey, I have seen every version of this. The good news is that almost all of it is fixable, and not every cracked driveway needs to be torn out and replaced. The trick is knowing what your slab actually needs, a real repair, a partial section pour, an extension, or a full tear out and rebuild. I will look at it honestly and tell you the right call for your house.

Driveway Demolition and Tear Out

Sometimes the slab is past saving. If you have multiple wide cracks running across the driveway, sections that have heaved more than an inch, or large areas where the surface is flaking down to the aggregate, a tear out is usually the smart move. I break up the old concrete, load it out, and haul it off. None of it gets left behind to deal with later.

Then comes the part most people never see, the base. South Jersey soil is mostly clay with sandy pockets, and clay holds water. If you pour fresh concrete on a base that was not compacted right or that drains poorly, the new slab is going to crack just like the old one did. I dig down, set a proper stone base, and compact it in lifts before any forms go in. That is the part that decides whether your new driveway lasts ten years or thirty.

Pouring a New Driveway

For new pours I set forms to grade so water runs off the slab and away from your foundation, not toward it. I tie in rebar where it makes sense, place the concrete at four inches for a standard residential driveway, and finish it broom for traction. Then I cut control joints in the right spots so when the slab does shrink (and concrete always shrinks a little as it cures), the cracks happen where I want them, hidden in the joints, not random across the surface.

Mix design matters too. Around here we deal with hard freeze thaw cycles from December through March, so I use a mix with the right air entrainment to handle it. Cheap concrete with the wrong mix is how driveways start spalling after two winters. I have re-poured plenty of those for homeowners who got the lowest bid the first time.

Driveway Extensions and Side Pads

A lot of homeowners around Voorhees, Marlton, and Mount Laurel call me to widen the existing driveway, add a side pad for a second car, or pour a new pad for a camper or work truck. Extensions are straightforward when they are done right. I tie the new pour into the existing slab with rebar dowels so the seam holds together instead of separating in the first winter. I match the slab thickness, set the joint where it makes sense, and make sure the new section grades the same way as the rest so you do not get a low spot that holds water.

If your existing driveway is already in rough shape, I will tell you straight. Sometimes the smarter move is to tear out the whole thing and pour a single clean slab the new size you want, rather than tying new concrete to a slab that is already failing.

Crack Repair, Spalling, and Sunken Slabs

Not every concrete problem needs a tear out. Hairline cracks I chase out with a crack router, clean, and fill with a flexible sealant that moves with the slab as it expands and contracts. Surface spalling from de-icing salt or a bad initial finish can sometimes be resurfaced with a polymer-modified overlay, depending on how deep it goes. Sunken porch landings, sidewalk slabs, and apron sections from settled subgrade can be lifted and re-bedded, or cut out and re-poured to grade.

The wrong move is painting or skim coating over a real structural problem. It looks fine for a season, then the crack telegraphs back through. I would rather give you the honest fix the first time, even if it is more work, than do the cheap thing and have you call me back in a year.
