Why homeowners pick Tri-County
Commercial sidewalks and public-facing access routes need the right grades, curb cuts, and tactile warning pads. We build those details into the scope from the start.
A broom finish gives walkways traction in wet Delaware weather. It is practical, clean, and required on sloped access routes.
Right-of-way work can involve DelDOT or municipal approvals. We coordinate permits and inspections when the sidewalk crosses into public-facing requirements.
Details
A cracked or uneven walkway changes how people move through your property. For homeowners, it hurts curb appeal and makes the front entrance feel tired. For businesses, HOAs, and property managers, it can become a trip hazard, an insurance issue, or an ADA compliance problem. Tri-County Construction installs residential concrete walkways and commercial sidewalks across Delaware with the right thickness, finish, and permit path for the job.
Residential walkways are typically poured 3–4 inches thick for paths to front doors, side gates, back patios, and outdoor spaces. Commercial sidewalks are usually 4–6 inches thick and may require ADA grades, curb cuts, ramps, or tactile pads. We form straight runs, curves, and angled layouts using flexible forms and steel stakes so the finished path works with the property instead of fighting it.
The difference between a walkway and a sidewalk is often permit ownership. Private walkways are usually on your property. Sidewalks can be public-facing or in the right-of-way, which can bring DelDOT or municipal requirements. We handle both, including slip-resistant broom finishes and visual continuity with nearby driveways, patios, and hardscape.
