How thick should a concrete slab be?

It depends on what the slab will support. For residential uses like shed pads or light storage, 4 inches is usually enough. For garage floors, RV pads, or areas with heavy equipment, we recommend 6 inches or more. We will assess your needs and recommend the right thickness.

Can I pour a slab over dirt?

Not directly. The dirt needs to be compacted and a gravel base needs to be added first. Pouring concrete directly on loose dirt leads to settling, cracking, and failure. Proper base prep is not optional if you want a slab that lasts.

How long does it take to pour a slab?

Most residential slabs can be poured in one day, though site prep might take a day or two depending on conditions. The concrete needs to cure for at least 7 days before you put heavy loads on it. Full strength develops over 28 days.

What Is Flatwork

Flatwork is any horizontal concrete surface. That includes driveways, patios, walkways, and slabs for buildings or equipment. Here in Compton, we pour concrete slabs for all kinds of projects: shed foundations, garage floors, RV pads, storage areas, workshops, and outdoor living spaces. If you need a flat, stable surface that can handle weight and weather, concrete is the answer.

A properly built slab gives you a clean, level area that does not shift, sink, or turn into mud. It provides a solid base for whatever you need to put on it. Whether you are building a new structure or just want a place to park your trailer, quality concrete flatwork in Compton, CA makes the space usable and keeps it that way for decades.

Why Site Prep Matters

The secret to a long-lasting concrete slab is what happens before the concrete truck shows up. If the ground is not prepared correctly, the slab will crack, settle, or break apart over time. We take site prep seriously because we know it makes the difference between a job that lasts 5 years and one that lasts 50.

Here is what needs to happen:

•Clear the area: Remove grass, roots, debris, and anything else that could interfere with the slab
•Excavate to proper depth: Dig down far enough to allow for base material and the thickness of the concrete
•Compact the soil: Loose dirt will settle and cause cracks. We use heavy equipment to pack it solid
•Add a gravel base: This layer helps with drainage and provides a stable foundation for the concrete
•Install reinforcement: Rebar or wire mesh strengthens the slab and prevents cracking

If you also need concrete foundations or footings, we can handle that at the same time. Everything gets built to the same high standard.

Our Process for Pouring Slabs

We follow a proven process on every flatwork job. You will know what to expect at each step, and we will keep the work area safe and organized.

Step 1: Site Assessment and Layout

We measure the area, check drainage, and mark where the slab will go. If there are utility lines or other obstacles, we work around them safely.

Step 2: Excavation and Base Prep

The ground is excavated, leveled, and compacted. We add gravel and install any necessary reinforcement like rebar or wire mesh.

Step 3: Forms and Pour

Forms are set to hold the concrete in place. Concrete is poured, spread evenly, and finished to your specifications. Control joints are cut to manage cracking.

Step 4: Curing and Cleanup

The slab needs time to cure and reach full strength. We protect it during this process and clean up the site before we leave.

We also handle concrete patios and other outdoor flatwork using the same reliable process. Everything is built to last.
