Monolithic Slab Installation in Greenville SC

One Pour. Total Strength. Built for Upstate Terrain.

If you’re building a new structure in Greenville SC—whether it’s a garage, small home, or accessory dwelling unit—chances are a monolithic slab is the right way to begin. At Sampson Concrete, we specialize in monolithic slab installation that combines foundation and footing into a single, continuous pour. It’s a cost-effective, time-efficient, and highly durable solution, especially suited to the clay-heavy soil and elevation changes that are common across the Upstate.

From the gently rolling hills of Parkins Mill to flatter suburban lots near Verdae, our team installs monolithic slabs that are level, reinforced, and built to support the weight of your structure for decades to come.

What Is a Monolithic Slab?

A monolithic slab is a concrete foundation where the footing and the slab are poured at the same time. Unlike traditional foundations that require separate excavation and multiple pours, a monolithic slab streamlines the process—saving you time and money without sacrificing quality.

It’s ideal for:

• Detached garages and workshops

• Guest houses or backyard studios

• Small primary residences

• New home construction on stable, well-drained soil

We’ve poured monolithic slabs in areas near Augusta Road, around Cleveland Park, and on wooded properties with custom home builds north of downtown.

Why Monolithic Slabs Are Perfect for Greenville SC

Greenville’s soil can shift when saturated, especially in lower-lying areas. A monolithic slab—properly reinforced and installed—resists cracking, settling, and erosion better than DIY foundations or piecemeal construction. Benefits include:

• Increased structural strength from integrated footing and slab

• Fewer seams and joints = less risk of water infiltration

• Faster construction timeline than multi-pour foundations

• Cost-effective for garages, tiny homes, and additions

• Reduced excavation, ideal for smaller lots or tight builds

Our slabs are designed for long-term performance, whether you’re supporting parked vehicles, framed structures, or concrete walls.
