Commercial Concrete in the Myrtle Beach-Conway SC Area
The Myrtle Beach-Conway corridor is one of South Carolina’s most active commercial development zones. Coastal Carolina University’s expansion, the retail and service growth along US 501, and the ongoing residential development of Horry County’s interior all create sustained demand for commercial concrete — parking lots, loading areas, retail flatwork, and warehouse floors. This guide addresses what business owners, developers, and property managers need to know about commercial concrete in the Conway area, including specifications, permit requirements, cost structures, and how to choose a contractor for commercial work. In this post, we cover what distinguishes commercial concrete from residential, the most common project types in the area, and the planning process for Conway commercial projects.

Why Commercial Concrete in Conway Is Different
Commercial concrete differs from residential in several important ways that affect both cost and outcomes. Load requirements are higher: a residential driveway handles 3,000–6,000 lbs of vehicle weight; a commercial parking lot handles those loads repeatedly across thousands of visits and must also accommodate delivery trucks, fire department access, and occasionally heavy equipment. Specifications must reflect these loads.
Permitting is mandatory: all commercial concrete projects in Horry County and the City of Conway require building permits. The City’s building department reviews commercial projects for ADA compliance, drainage requirements, and structural specifications. Commercial contractors must hold appropriate state licensing — residential-only licenses are insufficient for commercial work.
Drainage engineering is more complex: commercial lots often have larger impervious surface areas, which means stormwater management requirements from Horry County apply. Projects that exceed certain impervious surface thresholds require engineering review for stormwater management. Working with a contractor familiar with these requirements prevents permit delays.
Types / Options: Commercial Concrete in the Conway Area
Parking lots are the most common commercial concrete project in the Conway market. Standard commercial parking concrete is 5–6 inch thick with rebar reinforcement, specified at 4,000–4,500 PSI. Drainage slope of 2% is standard across parking field areas, with curb and gutter or valley gutters directing water to retention areas. Cost: $4–$7 per square foot installed for standard specifications in the Myrtle Beach-Conway market.
Loading docks and truck approach areas handle the heaviest vehicle loads and require thicker sections — typically 7–8 inches with heavier rebar — at the point of maximum stress. Loading dock approaches in Horry County often require engineered drawings due to their structural significance. Cost: $7–$12 per square foot for heavy-duty sections.
Retail and restaurant flatwork (sidewalks, entry approaches, outdoor dining pads) serves as the public face of commercial properties. These applications must meet ADA slope requirements, be finished to a safe texture, and use expansion joints that prevent trip hazards as the concrete ages. Cost: $5–$8 per square foot for properly specified commercial flatwork.
Warehouse and industrial floors require flatness tolerances and surface hardness specifications that residential contractors rarely work to. Laser-screeded floors for forklift operations, epoxy-coated finished surfaces, saw-cut control joints in precise patterns — these are the hallmarks of properly executed industrial concrete. Cost: $5–$10 per square foot depending on specifications and size.
Practical Uses
New retail development along US 501: The Conway-Myrtle Beach corridor along US 501 sees consistent new retail and service development. A typical 10,000 sq ft retail pad’s exterior concrete — parking, drive aisles, walk areas — runs 30,000–50,000 sq ft of concrete work at $4–$7 per square foot. These projects require stormwater engineering, ADA review, and commercial permits. Conway Concrete Pros has the licensing and commercial experience to handle this scope.
Restaurant outdoor dining expansion: Conway’s hospitality sector, connected to the broader Myrtle Beach tourism market, sees frequent requests for concrete outdoor dining areas. A 1,000 sq ft outdoor dining pad in decorative broom-finished or stamped concrete runs $5,000–$12,000 depending on finish and drainage complexity. ADA accessibility requirements apply.
Medical or professional office parking lot: A 50-space parking lot serving a medical office or professional building in Conway typically requires 30,000–35,000 sq ft of concrete. At $4–$7/sq ft with full base prep and drainage, budget $120,000–$245,000 for the concrete scope alone. Permits, engineering, and stormwater management are additional.
Coastal Carolina University area development: Commercial development near CCU serves the student and faculty population with retail, restaurants, and services. These projects frequently involve building footprints on previously undeveloped land — which means new construction base engineering on native or recently graded Horry County soil. The same fill-soil preparation considerations that apply to residential new construction apply here, amplified by heavier commercial loads.
Warehouse floor for inland distribution: Conway’s position between Myrtle Beach and the inland SC highway network has attracted warehouse and distribution use. New warehouse floor installations in the 10,000–50,000 sq ft range are a growing segment of Horry County commercial concrete. These projects require laser leveling, specified PSI above 4,500, and appropriate control joint layout for forklift traffic patterns.

How Commercial Concrete Projects Work in Conway
Commercial projects in Conway typically proceed through a more formalized process than residential work: proposal development (often requiring engineering drawings for larger projects), permit submission, scheduling with the City or County building department for inspection coordination, phased construction to maintain business access, and final inspection before occupancy.
The permitting timeline for commercial concrete in Conway typically runs 2–4 weeks after complete document submission. Projects that require stormwater engineering add time to the pre-submission phase. Planning for a 4–6 week lead time from initial contact to permit approval helps commercial clients avoid scheduling disruptions.
Frequently Asked Questions
What permits are required for commercial concrete in Conway SC?
All commercial concrete projects in Conway and Horry County require building permits. The City of Conway Building Department handles permits within city limits; Horry County Code Enforcement handles unincorporated areas. Projects with significant impervious surface coverage require Horry County Stormwater Management review. Contractors must hold valid South Carolina General Contractor licenses for commercial work — a residential builder’s license is not sufficient.
How long does commercial concrete take to cure before opening to traffic?
Standard commercial concrete cures to 70% of design strength at 7 days — sufficient for passenger vehicle traffic. Full 28-day cure is required before heavy truck traffic and forklift use on loading areas. For business operations, this means phasing the project to allow portions of the parking to remain accessible during construction, or accepting a 7–14 day window before the space is fully operational. We plan project phasing around business needs during the proposal phase.
How much does commercial concrete cost per square foot in Conway?
Standard commercial parking and flatwork runs $4–$7 per square foot in the Conway and Myrtle Beach market, consistent with the area’s concrete pricing of $200–$238 per cubic yard. Heavy-duty loading areas and industrial floors are priced higher at $7–$12 per square foot. Base preparation, drainage engineering, permits, and traffic control (for occupied sites) are additional cost items. We provide detailed commercial proposals that itemize all scope elements.
