Oak Island is a barrier island in Brunswick County, reached by the bridge from NC 133, with the Oak Island Lighthouse, beach cottages and homes raised on pilings. Concrete here meets salt, wind, blowing sand and storm surge every year. It has to be built tougher than concrete inland.
Coastal Concrete Wilmington is a locally owned concrete company in Oak Island NC. We build driveways, patios and pads, and we give a free written estimate before work starts.
Concrete built for a barrier island
On Oak Island, salt air is constant, the ground is pure sand and the water table is high. Concrete needs steel that is well covered, a mix made for the weather and a sealer that blocks salt. A concrete company in Oak Island NC has to plan for all three.
We also plan for wind, since gusts can blow sand and dry fresh concrete in minutes.

- Pads for storage and equipment
- Repairs and sealing for salt wear
Sand, storms and flood rules
Barrier island sand washes easily. Storm surge can scour the ground around a slab, and heavy rain can leave voids. We compact bases in layers, thicken edges and add drainage. Flood zone and coastal rules can limit what can be built and how, so we help you check before we pour.
After a storm, we can look at slabs, walks and driveways and fill washed out voids. See concrete leveling and concrete repair.
Driveways and parking under raised homes
Many Oak Island homes sit on pilings with parking beneath. The slab there must be flat and strong, and it must drain well. See driveway installation, concrete slab installation and concrete staining and sealing.
We pick finishes that grip when wet and clean up easily.

Questions about hiring a concrete company in Oak Island NC
Do you work on Oak Island from your Wilmington shop?
Yes. Oak Island is a drive south of Wilmington, and we serve it regularly. We visit for a free estimate, measure the work and give a written price. For larger jobs, the trip is a small part of the cost. We plan the day around bridge and beach traffic, especially in summer.
Call us any day from 5 AM to 10 PM, give us your address and describe the work. If your home is raised on pilings or has a narrow lot, tell us, so we can bring the right equipment. We also plan truck access, since beach streets can be tight, and we tell you how long trucks will be on your street.
Tell us the type of home and the height of the pilings, and a concrete company in Oak Island NC can plan the slab before the visit. Ask us to review your home plans for any parking slab below the house.
How do you protect concrete from salt air on Oak Island?
We use a few simple steps. We cover the rebar with enough concrete so salt has a hard time reaching it. We use a mix made for outdoor use. We seal the surface with a product that blocks salt and water, and we suggest rinsing the slab with fresh water now and then.
Sealer wears off faster by the ocean, so plan to reapply every two years or so. Small cracks should be filled early, since salt water slips into them and rusts the steel. See concrete staining and sealing. We leave care notes after the job and can return to reseal when it is time.
A short walk after a storm shows us where sand moved, and we are glad to look and write up what we find. Tell us the age of your home and any past repairs, and a concrete company in Oak Island NC can plan new concrete to match what is already there.
Can you pour a driveway or slab under a home on pilings?
Yes. Parking beneath a raised home is common on Oak Island. The slab must be flat and strong, and it must drain, since wind blown rain and storm water pass through. We work around the pilings, the stairs and the utilities. We also look at flood rules, since some areas limit what can be built below the base flood level.
We check the rules with you before the pour, and we call NC811 before digging. See concrete slab installation. A free visit shows us the access, the pilings and the slope, and we give you a written price with a clear plan.
Rinse the slab with fresh water after beach days, since regular rinsing helps concrete near the ocean last longer. A concrete company in Oak Island NC should ask about wind and blowing sand, since both affect how we place, finish and cure a slab on a barrier island in summer.
What happens to concrete during a storm surge or flood?
Water can scour sand from around and under a slab, leaving voids and sagging edges. Debris can crack the surface, and salt water soaks in. Strong, thick slabs with good steel and tight edges stand up better, and drains help water leave fast.
After a storm, walk the slabs and look for gaps, cracks and washed out spots. Take photos. We can fill voids, lift settled slabs and repair edges. See concrete leveling. We also tell you honestly what is storm damage and what was already there. Good photos before and after help with insurance claims.
A concrete company in Oak Island NC should be honest about flood rules, and we tell you what we know and who to ask. Ask us how we handle trucks on narrow beach streets, since we plan delivery times, parking and the path of the chute so neighbors can still get in and out.
Is there a good finish for a beach house driveway or patio?
A light colored, textured finish is a good choice. A broom finish grips and costs little. Exposed aggregate has a natural stone look that suits the beach and hides sand. A good sealer is important, and a penetrating type keeps salt out without a slick surface.
Avoid smooth glossy finishes, since wet feet and wet sand make them slick. We bring samples and test them in the sun with you. See exposed aggregate concrete. We also slope the slab so rain and rinse water run off fast, which keeps algae and mildew from building up in the shade.
Sample boards in the sun show how a finish will look on the island, and we bring them to every estimate. Share photos of the washed out edges and any cracked steps, and a concrete company in Oak Island NC will tell you which repairs are urgent and which can wait for your off season.
How soon can you come out to Oak Island?
Usually within a few days. Call us any day from 5 AM to 10 PM, tell us what you want to build or fix and give us your address. We set a time to visit, measure and talk about your ideas. Photos of the area help, but they are not required.
After the visit, you get a written estimate with the work, the thickness, the finish and the price. There is no charge for the estimate and no pressure to sign. If you have a rental season or a deadline, tell us when you call. We plan backward from your date and tell you what is realistic.
Rental season matters, so tell us your dates, and we will plan the pour so the work is done before guests arrive. Ask us to plan the work for the quiet months, since scheduling a pour before or after the rental rush keeps guests happy and the crew working safely.
