Hardscaping in Portsmouth, NH

Hard Tech Construction builds patios, walkways, retaining walls, driveways and granite steps for homes and businesses in Portsmouth, New Hampshire. We are a locally owned hardscaping contractor based in Berwick, Maine, and Portsmouth is inside the area our crew covers every week.

What we build in Portsmouth

The same range we build everywhere, chosen to suit the property rather than a catalogue. Paver and natural stone patios with seat walls and, where it suits the yard, a fire pit or outdoor fireplace. Retaining walls in block, stone and granite where grade has to be held back before anything else can be built. Walkways and steps that stay level and drain, and granite steps and stonework at entrances. Driveways built on a base specified for vehicle weight, and pool decks with the right surface underfoot when wet.

For businesses and municipal property in Portsmouth we also build commercial sidewalks and ADA accessible routes, parking lot and entrance paving, public sidewalks and granite curbing.

Why the base matters here

Everything we build in New Hampshire has to survive frost. The surface is what you see, but the base is what keeps it flat. We excavate to depth, install and compact gravel in layers, and pitch the finished surface so water runs away from the house rather than sitting on it. Edge restraint holds the field in place and joint material locks the units together. Skipping any of that is why a patio looks right in October and is moving by April.

Getting a quote in Portsmouth

We walk the property, look at the grades, the drainage and how you actually want to use the space, and quote from that rather than from a phone call. Call (207) 464-0005 or use the form on this site.
