Waltham is our home city. We pour, cut and raise here.

A&B Waltham Concrete is based in Waltham. Much of our work here is flatwork, the slabs that sit flat on the ground, like concrete driveways, patios, walks and garage floors. We also take the tricky jobs, like cutting a new opening in a wall, raising a house or pouring where a truck can't get close.

We're licensed and fully insured, and we do the same work in Newton, Watertown and the other cities around Waltham.

I start under the slab. The finish comes after.

At the estimate I walk the site, ask how you'll use the concrete and look at what's under the old slab and where the water goes. Size, how much has to come out, the base and access set the price, and the schedule turns on any permit or engineer the job needs first. Your written estimate spells out what's included.

  • Whether the old base has sunk or washed out
  • Where the water runs off the slab
  • How a concrete truck reaches the pour
  • Which city office the permit goes through

The base matters most. Nobody sees it after the pour.

When the dirt is raked level instead of dug out and packed into a firm subgrade, the ground a slab sits on, the slab sinks as that dirt settles. A slab that falls toward the house sends water to your foundation, and skipped joints leave cracks wherever they want.

The base is the first thing people want to cut, because on day one you can't see it. I'd rather you spend there than on a fancier finish, so we dig down to firm ground, pack the base, slope the slab away from the house and plan control joints, cut lines that give cracks a straight place to go.

From your call to the walk-through. Here's how it runs.

  1. 01. You call or write

    Call or send the form with a few lines about the job, what's sinking, cracking or pooling, and we'll set a time for me to come out.

  2. 02. I come out and look

    I come out myself, look at the site and ask how you'll use the concrete, because a parking pad and a patio aren't built the same way.

  3. 03. Your written estimate

    You get it in writing with what's included, then we line up any permit, surveyor or engineer before the pour goes on our schedule.

  4. 04. The pour and the walk-through

    Our crew works within the city's posted hours, 7 am to 5 pm weekdays and 8 am to 4 pm Saturdays. We walk the finished job with you before we leave.

Permits, rules and cracks. Answered plainly for Waltham.

Here are straight answers on permits, contractor rules and what to expect from a new slab. If your question isn't here, call and I'll answer it.

Do I need a permit for a concrete driveway in Waltham?

The Waltham Building Department is the office to ask, because it issues building permits here and its list of small projects names work like roofing and siding, not driveways. We work out which city office your job runs through, handle the permit steps for our work and tell you early if we need your signature.

How much does a residential building permit cost in Waltham?

Waltham charges $12 per $1,000 for residential permits, with a $50 minimum fee. Permits for small projects can be paid up front. If your job needs one, I'll point that out when I come out for the estimate.

Does a concrete contractor in Massachusetts need HIC registration?

Yes, for work on an existing home you live in with one to four units, Massachusetts requires Home Improvement Contractor registration. New construction, buildings over four units and vacation or investment properties fall outside it. The registration number has to show on permits, contracts and ads, and covered jobs of $1,000 or more need a written contract.

How long will I be without my driveway after new concrete is poured?

You're off it through the tear-out, the base work, the pour and the curing, the wait while the concrete gains strength before it can carry a car. You can walk on it well before you can drive on it. Size, access and the mix all change the wait, so I'll go over yours at the estimate.

Will my new concrete driveway crack like the old one?

It shouldn't crack the same way if the old base was the cause, because we dig it out and pack it instead of pouring over loose dirt. Concrete can still crack, so we cut the joints on time to steer it and plan the pour away from midday heat, which can leave a weak, dusty top.
