Commercial Sidewalks and ADA Accessible Walkways
Hard Tech Construction builds commercial sidewalks, entrance walkways and ADA accessible routes for offices, retail plazas, medical buildings and multi-unit properties across southern Maine and the New Hampshire Seacoast. The walkway is the first thing a customer or tenant touches on your property, and it is also the surface most likely to generate a complaint or a claim if it is built wrong.
Accessible routes are a build detail, not a sign
An accessible route has to hold a running slope no steeper than 1:20 unless it is built as a ramp, and a cross slope no steeper than 1:48. Those numbers sound small on paper and they are unforgiving in the field, because a walkway that drains well is fighting the cross slope limit the whole way. Getting both right at once is the actual skill.
We lay out the route before we excavate, shoot grades across the full run, and build to the tighter of the two constraints. Where a site cannot hold the running slope, we build a proper ramp with landings at the top and bottom, handrails where the rise calls for them and a level area at every door. Detectable warning surfaces go in at curb transitions and vehicle crossings.
Surfaces that stay flat under real use
Commercial walkways take foot traffic all day, carts, deliveries, snow equipment in winter and the occasional vehicle that should not have been there. We build in poured concrete where you want a continuous surface and the lowest maintenance, and in pavers where you want the look, the ability to lift and reset a section without a visible patch, and a surface that tolerates ground movement better than a slab.
Pavers are worth a serious look on any property where utilities run under the walkway. When a line needs attention, the units come up and go back down and nobody can see where the work happened. On a concrete walk, that same repair leaves a permanent grey rectangle.
Drainage is what fails first
Almost every commercial walkway problem we get called about traces back to water. Water that sits on a walk in November is ice in December, and ice at an entrance is the single most expensive thing on a commercial property. Water that gets under the surface and freezes lifts slabs and pavers until the joint between them becomes a trip edge.
We pitch every surface so runoff leaves the walk, keep it moving away from the building rather than toward it, and tie into existing drainage where it exists. Where a low spot cannot be pitched out, we build in a drain rather than hoping. The base underneath is excavated to depth and compacted in layers, because in this climate the base is the whole job and the surface is just what you see.
Working around an open business
Most of this work happens on a property that cannot close. We phase the build so entrances stay usable, keep a signed accessible route open while we work on the primary one, and schedule pours and closures around your hours rather than ours. If your building has a delivery window or a shift change that cannot be blocked, tell us early and we will plan around it.
For municipal and public right-of-way work, the requirements and the inspection process are different, and that is covered on our public sidewalk installation page.
Entrances, steps and the rest of the approach
A walkway usually arrives somewhere. Entry steps, landings and the transition from parking to building are part of the same design, and building them together is how you avoid a mismatched patch where two contractors met. We build granite steps and stonework for commercial entrances, retaining walls where grade has to be held back along a route, and parking lot and entrance paving where the approach needs work too.
