Why homeowners pick Tri-County

Built for Delaware weather, finished to last

Drainage Comes First

A patio that holds water fails fast. We plan pitch before the pour so water moves away from the house and usable areas.

Joint Layout Matches the Patio

Control and expansion joints are cut around the actual patio shape. That keeps movement controlled without making the finished space look like an afterthought.

Finish Options That Fit the Space

Choose broom, smooth trowel, exposed aggregate, stamped patterns, integrated borders, integral color, or post-pour stain. The finish should match how you use the patio.

Details

A concrete patio turns unused yard space into a clean outdoor room.

A concrete patio should do two things: look good and stay solid. Too many Delaware homeowners live with muddy grass, unstable pavers, or an old slab that pools water after every storm. Tri-County Construction pours backyard and side-yard patios to your actual use case, whether you need a grill area, dining space, firepit zone, hot tub pad, or pergola foundation.

The details matter before the concrete truck arrives. We set the patio elevation, pitch the slab for drainage, form the shape, and cut joints around the layout instead of forcing a generic grid onto the finished space. Standard finishes include broom, smooth trowel, exposed aggregate, stamped concrete patterns, and integrated borders. Premium upgrades can include integral coloring, post-pour stain, or a stamped finish that ties into walkways and walls.

If your pavers have shifted or your yard turns soft every spring, a properly poured concrete patio is a permanent upgrade. It gives you a stable surface for furniture, grills, and outdoor living while avoiding the weeds and settlement issues that come with loose systems. Seal the patio within 30 days and maintain it every 2–3 years for the cleanest long-term look.

FAQ

Common questions

Don't see your question? Call (302) 419-3232 or send a quick note through the contact form — we usually reply same-day.

How big should a concrete patio be?
Plan for at least 16x16 ft for dining and a grill, and larger if you want lounging space. We spec the size with you during the estimate.
Can you pour a concrete patio over an existing one?
Sometimes — it depends on the old slab condition and elevation relative to your house. Most of the time, tear-out and repour is the better long-term fix.
Do concrete patios stain easily?
With a quality sealer applied within 30 days, no. Without sealer, rust, oil, and leaves can stain the surface. Resealing every 2–3 years keeps it looking new.
What affects the cost of a concrete patio in Delaware?
Patio pricing depends on square footage and slab thickness, site prep and grading requirements, reinforcement (rebar or wire mesh), finish type (broom, smooth, exposed aggregate, stamped), access for the concrete truck, and removal of any old surface or grass. Every project gets a free on-site estimate — call (302) 419-3232.
