Concrete Patios in Murphy, Texas

Patios for outdoor kitchens, fire pits and covers

Murphy's fee schedule charges $100.00 each for an arbor or patio cover, an outdoor fire pit or fireplace, and an outdoor kitchen, on top of the $100.00 residential flatwork permit for the slab itself.

Thickness under heavy features

A patio slab is generally at least 4 inches thick, but a hot tub or outdoor fireplace calls for 5 to 6 inches. For scale, a 12-by-12-foot patio 4 inches thick takes about 1.78 cubic yards of ready-mix concrete. The City's flatwork handout lists no thickness or strength for private slabs; the National Ready Mixed Concrete Association's figure for exterior slabs is 4,000 psi, consistent with the ACI 332 residential code.

Slope and drainage

The U.S. Department of Energy's Building America guide says patios, porch slabs and walks within 10 feet of a foundation should slope away at a 2% grade, and ENERGY STAR recommends at least 0.25 inch per foot. We'll talk through where water goes before the forms are set.

From Collin County farmland to a turnpike suburb

The first settlers arrived in 1846, drawn by Peters Colony land grants, says the Handbook of Texas. The City of Murphy names Comfort and Lydia McMillen, who came from Arkansas with their six children and settled on a branch of Muddy Creek later called Maxwell Creek. The town took William Murphy's name when the St. Louis Southwestern Railway arrived in 1888 on land he provided, and it stayed a farming community into 1970, shipping cotton, corn and onions. The Old Murphy Schoolhouse was built in 1938 as a WPA project.

Growth came late. The Handbook counts 136 residents in 1970, 1,547 in 1990 and 3,099 in 2000. In the 1980s families moved in on lots of 1 to 5 acres, and the City says residential growth has been strong since the President George Bush Turnpike opened in 2000. The 2020 Census counted 21,013 people.

What the housing looks like

About half of Murphy's housing was built before 2005 and half after, going by the Census Bureau's 2020–2024 median; about 81% of units date from 2000 or later, and about 98% are single-family detached. Owners live in about 94% of occupied homes, and the survey's median value for an owner-occupied house is $555,500. The SF-E estate district requires lots of at least 40,000 square feet.

Parks and landmarks

Murphy Central Park, at 550 North Murphy Road, has an amphitheater seating 2,500 to 3,000, a 2-acre stocked pond and about 0.6 miles of 8-foot concrete trail linking to the Maxwell Creek Trail. Timbers Nature Preserve was first built in 2000 as Murphy City Park and was renovated and expanded in 2015, and Murphy Marketplace, built in 2008 at North Murphy Road and East FM 544, is the city's main shopping center.

Summer heat and the ground underneath

NOAA's 1991-2020 normals put the June-August average high at DFW Airport at 94.3°F, and the NRMCA says wind over 5 mph, low humidity and high temperatures raise the risk of plastic shrinkage cracks, which form when the surface dries before the concrete sets. In cooler months it wants new concrete kept above 50°F while it cures.

The Soil Science Society of America's booklet on Houston Black, Texas' unofficial state soil and a Blackland Prairie clay, explains the cracking: the soil is high in smectite, a clay that swells as it gets wet, shrinks as it dries and cracks the ground. We'll look at the soil and drainage at your house before planning the base.
