Concrete Slabs & Flatwork

The Foundation of Many Projects

Concrete slabs and flatwork are the backbone of countless residential and commercial projects. Whether you need a floor for a new garage, a pad for equipment, or a level surface for a shed or workshop, the quality of the slab determines how well everything else performs.

At KeenCraft Corona Concrete, we've been pouring concrete slabs in Corona since 2024. We know that seemingly simple flat concrete requires careful attention to base preparation, proper thickness for the intended use, correct reinforcement, and accurate finishing. Cut corners on any of these, and you'll have problems down the road.

Where We Install Concrete Slabs

Concrete slabs serve many purposes for Corona property owners:

• •Garage floors: A properly sloped, level garage floor makes vehicle entry easier and helps prevent water pooling. We can add epoxy coatings or other finishes for added durability.
• •Equipment pads: AC units, generators, hot tubs, and pool equipment all need stable, level bases. We size and reinforce slabs appropriately for the equipment weight.
• •Shed and workshop foundations: A solid slab provides a much better base than gravel or bare ground, preventing settling and making the interior space more usable.
• •RV parking pads: Heavy RVs need substantial support. We install thicker slabs with extra reinforcement to handle the weight without cracking.
• •Commercial flatwork: Warehouse floors, loading areas, and utility spaces all require specialized concrete work designed for heavy use.

Each application has different requirements for thickness, reinforcement, and finish. That's why experience matters. We've seen what works in Corona's conditions and can guide you to the right solution for your needs.

What Goes Into a Quality Concrete Slab

Site Preparation

Everything starts with the ground below. We excavate to the proper depth, removing vegetation, roots, and unsuitable soil. In Corona, we sometimes encounter expansive clay soils that need special attention. We'll install a compacted gravel base that provides stable support and helps with drainage.

Formwork and Grading

We set forms to exact dimensions and heights, using laser levels to ensure proper slope for drainage where needed. For most slabs, a slight slope (1/4 inch per foot) directs water away from buildings and prevents pooling.

Reinforcement

Concrete is strong in compression but weak in tension. That's where reinforcement comes in. We use rebar or wire mesh positioned correctly within the slab thickness to prevent cracking from shrinkage and loading. The type and amount of reinforcement depends on the slab's intended use.

Pouring and Finishing

We use concrete mixed to the right specifications for your application. As we pour, we work the concrete to eliminate air pockets and ensure full coverage. Then we finish the surface to your requirements: smooth trowel finish for garage floors, broom finish for traction, or whatever your project needs. We also cut control joints at appropriate intervals to guide any cracking that might occur.

How Thick Should Your Slab Be?

One of the most common questions we get is about slab thickness. Here are general guidelines:

4 inches is standard for residential applications like sheds, light storage, or sidewalks. 5-6 inches works for garage floors and areas with regular vehicle traffic. 6-8 inches is necessary for heavy equipment, RV parking, or commercial applications where forklifts or trucks will operate.

But thickness isn't everything. A 6-inch slab poured on poorly prepared ground will fail faster than a 4-inch slab on a properly compacted base. We design each project based on your specific situation, soil conditions, and intended use. That's also why our work relates to other services like foundations and driveways, where proper engineering makes all the difference.
