OUR CONCRETE SLAB INSTALLATION PROCESS
A dependable slab starts with the right prep and process. At Coast Salish Concrete, we follow a five-step approach to deliver slabs that are stable, level, and ready to build on.
Step 1
Site Prep and Grading
We begin by clearing the area and grading it carefully to promote drainage and establish a stable foundation. This sets the tone for the rest of the slab's performance.
Step 2
Form Setting
Our team installs forms to shape the perimeter and structure of your slab. We double-check alignment and elevation to match your build requirements.
Step 3
Base and Reinforcement
We compact the sub-base and install rebar or mesh reinforcement to support the slab’s strength and reduce the risk of shifting or cracking over time.
Step 4
Concrete Pouring
We pour high-quality concrete evenly across the formwork, ensuring a uniform surface and consistent depth throughout the slab.
Step 5
Finishing and Curing
The surface is smoothed to your requested finish, whether broomed, slick, or ready for flooring. We then allow proper curing to lock in strength and durability.
WHY CHOOSE A PROFESSIONAL CONCRETE SLAB CONTRACTOR?
Improper grading, rushed prep, or a lack of reinforcement can lead to water issues, cracks, and costly delays. Hiring a contractor who understands the full process is key to getting it done right. When you work with Coast Salish Concrete, you get:
- A properly poured slab that meets grade, depth, and support standards
- Clear communication and dependable timelines
- Reinforced, well-prepped work that minimizes movement and drainage problems

FREQUENTLY ASKED QUESTIONS
We know that planning for a concrete slab is a major step in any project. These answers are designed to help you move forward with confidence, knowing Coast Salish Concrete handles every detail with care and precision.
How thick should a concrete slab be for a garage or addition?
Most residential slabs are typically 4 to 6 inches thick. For garages or additions that require extra support, we may recommend a thicker pour depending on load requirements and soil conditions. We’ll assess your project and recommend the right thickness to ensure long-term performance and stability.
Do I need to remove the old slab before pouring a new one?
In most cases, yes. Removing the old slab helps ensure a stable and level foundation, especially if the existing concrete has shifted, cracked, or settled over time. Our team will evaluate the site and advise whether a full removal is necessary or if the existing slab can serve as a suitable base.
What kind of reinforcement do you use?
We typically use rebar or welded wire mesh to reinforce slabs, depending on the project type. Reinforcement improves strength, minimizes the risk of cracking, and supports heavy loads. We also compact the base and use control joints to further prevent movement or stress fractures.
How long before I can build on the slab?
While concrete begins curing quickly, we recommend waiting at least 7 days before beginning light framing and 28 days for full structural loads. We’ll guide you based on your slab’s purpose, size, and site conditions to ensure it’s ready before you move forward.
