Merrimack driveways, patios and the ground under them
Most of the concrete calls we get in Merrimack come from single-family homes on wooded lots, from older capes and ranches to bigger colonials in newer neighborhoods, plus some small businesses along the main roads. A lot of driveways here are long, went in with the house and have spent decades under plows, so they're the slabs we look at most. The yards are a lot like the ones we work on in Bedford and Amherst, with garages set back from the road and backyards that slope toward the trees.
That shapes the job before we ever pour. Long driveways mean more base to dig out and pack, wooded lots mean roots and rocks once we open the ground, and an old slab usually has to come out first, so prep is often the bigger part of the work.
Concrete work we do for Merrimack homes and businesses
Concrete driveway building
Long Merrimack driveways that went in with the house often settle, so we dig out the old base, pack new stone and pour a slab ready for plowing.
Concrete patio construction
A backyard patio here often sits where roots and rocks run underneath, so we clear and pack the ground and slope it away from your house.
Stamped concrete services
Stamped concrete gives a patio or walk the look of stone or brick, and we seal it so the pattern holds up through our winters.
Concrete sidewalk building
Front walks that have heaved or tipped toward the house are common here, so we rebuild them on packed stone with a slight pitch that sheds water.
Garage floor concrete
Winter salt and slush wear out older garage floors here, so we pour a fresh slab with control joints, cuts that tell cracks where to go.
Decorative concrete
Colored or patterned finishes suit the newer colonials and front entries we see in Merrimack, and we pick one that keeps its grip when it's icy.
Concrete retaining walls
Sloped backyards are common on Merrimack lots, and a poured retaining wall holds the hillside back so you get flat ground for a patio or play area.
Concrete floor installation
Basements, workshops and outbuildings here often need a floor poured level and smooth, and we set the base and vapor barrier first to keep ground moisture under it.
Concrete pool decks
Pool decks here go through hot summer sun and hard freezes, so we use a textured finish for bare feet and slope the deck away from the water.
Concrete steps construction
Front and back steps on older Merrimack houses often crumble at the edges, so we form and pour new ones with steel inside and even step heights.
Slab foundation building
Additions, sheds and garages around Merrimack often sit on a slab foundation, and we dig and pack the subgrade, the ground the slab rests on, before we pour.
Foundation installation
When builders and homeowners here put up a new house or addition, we form and pour the foundation walls, with the planning done before the first truck arrives.
Concrete parking lot building
Small businesses along Merrimack's main roads need parking areas that take daily traffic and plowing, so we build a thicker slab on a deep packed base.
Concrete footings
Decks, porches and additions need footings set below where the ground freezes in New Hampshire, and we dig and pour them to the plans for your job.
Foundation raising
If part of an older foundation here has sunk or tipped, we look at what's under it and plan the lift and support before anything moves.
Concrete cutting
We cut openings, trenches and clean lines in existing slabs, from making room for a basement drain in Merrimack to removing a damaged section of driveway.

Working in Merrimack: permits, scheduling and price
Building permits in Merrimack come from the Merrimack Building Division, and that office decides what your concrete job needs, so we work to what they ask. We'll help you confirm it's the right office for your job and get the paperwork moving, and because any permit has to come through before we dig, starting early keeps the pour date from sliding. We're licensed and insured, and you're welcome to ask us for proof before you sign anything.
Merrimack sits between Manchester and Nashua, and we do the same work in both, so our crew is rarely far from your driveway. Your price moves with the size of the slab, how much old concrete comes out, how deep we dig to reach firm ground, how thick the slab needs to be and the finish you pick, and the estimate gives you your own number. The base is the part nobody sees once we pour, so it's the first thing people want to cut, and it's the last place I'd cut, because a fancy surface on a soft base sinks and cracks like any other slab.
Winters and wet ground are hard on slabs here
New Hampshire winters freeze and thaw the ground over and over, and when water sits under a slab it swells as it freezes, lifting and cracking concrete laid on loose dirt. That's why we dig out soft soil, pack crushed stone in layers and cut the control joints as soon as the concrete will take the saw, so cracks tend to fall in the joints instead of across the middle of your driveway.
Merrimack's zoning marks wetlands, flood hazard and aquifer conservation districts across parts of the city, and on lots near low, wet ground we look hard at where the water runs before we set a form. A patio or driveway that falls back toward the house sends meltwater at your foundation, so we pitch the slab away from it.
How a concrete job runs when you call us in Merrimack
Here's how a job goes from your first call to the day you can use the slab, and who you'll deal with along the way.
Call or send the form
Tell us where the slab goes and what it's for, by phone at (603) 377-5028 or through the form. We'll set a time that works for me to come out.
I look at the spot
I come out myself, walk the area, ask how you'll use it and check where the water runs. You'll have an estimate on site before I leave, so you know the price before anything starts, and it helps if you're home to walk it with me.
Permit, prep and pour
Once you say go, we get any permit paperwork moving, then our crew digs out and packs the base. I'm on site with the crew for the pour and the finish, and we plan the pour around the weather instead of rushing it in midday heat.
Curing and what to watch
Curing, the slow hardening that gives concrete its strength, needs time, so before we leave I'll tell you when you can walk on the slab and when you can drive on it. I'll also tell you what to watch for that first winter, like where water pools after a rain.
Questions about concrete work in Merrimack, NH
How much does a new concrete driveway cost in Merrimack, NH?
The cost of a Merrimack driveway is set mostly by its length and the base work under it, so a long driveway on soft or wet ground costs more than a short one on firm soil. Tearing out the old driveway, how easily the concrete truck can reach the spot and a stamped or colored finish all add to it, while a plain broom finish, the lightly brushed texture that gives tires and boots grip, keeps it down. I'll give you your own number when I come out to look.
How do I apply for a building permit in Merrimack, NH?
You apply through the Building Division's permit page, which takes building permit applications online through OpenGov. The division posts its current permit fee schedule there too. If your concrete job needs a permit, we'll help you pull the paperwork together.
Which building code applies to a Merrimack permit filed after January 1, 2027?
From January 1, 2027, every permit request in Merrimack has to follow the updated New Hampshire State Building Code. Through December 31, 2026, requests can still be filed under either the older or the updated version, and the state code sets the minimum for buildings and structures in every municipality in the state. If your job lands close to the switch, we'll plan the paperwork around it.
How long does a new concrete patio or driveway take to cure before I can use it?
You can walk on a new slab well before you can drive on it or set heavy furniture down, and I'll give you both days for your pour before we leave. Curing goes slower in cool fall weather and faster in summer heat, and we keep a fresh slab from drying out too fast, because that's what leaves a weak, dusty top that chips later.
What causes concrete driveways to crack and sink in Merrimack?
Most of the cracking and sinking I'm called to look at starts under the slab, where loose dirt was raked flat instead of dug out and packed, then settled and froze through a few New Hampshire winters. Joints cut late or skipped let cracks run wherever they like, and a slab poured in midday heat can end up with a weak top. Concrete can still crack, but a packed base and joints cut on time usually keep cracks small and in the joints.
Do I need a demolition permit to tear down an old garage before a new slab in Merrimack?
The Building Division issues a demolition permit for tearing down and removing a whole structure, so check with them before an old garage comes down. We'll help you find out what the division needs for the teardown and for the new slab, so neither one holds up the other.
