Expanding a home or commercial space is an exciting step—but one that starts beneath the surface. Before framing, electrical, or design begins, your project needs one critical element: a solid, expertly matched foundation addition.

At CBD Concrete, we specialize in adding to existing concrete foundations with seamless precision, ensuring structural integrity for everything that follows. Whether you're adding a room, extending your office, or constructing a new garage, we’ve got your base covered.

What Is a Foundation Addition?

A foundation addition is the process of extending your existing concrete foundation to support a new structure. It must be carefully planned and installed to:

• Match the elevation and strength of your current foundation
• Tie into the original slab or footings without cracks or movement
• Meet current building codes and engineering standards

Improper foundation additions can lead to uneven floors, wall separation, and structural stress—all of which are avoidable with the right team.

Common Projects That Require Foundation Additions

• Room Additions – Expanding a home with new bedrooms, offices, or living spaces
• Garage or Workshop Additions – Freestanding or attached expansions
• Sunrooms and Enclosures – Concrete bases for all-season spaces
• Commercial Expansions – Offices, storage wings, or showroom additions
• Accessory Dwelling Units (ADUs) – New builds in backyards or on investment properties

Our Process: Seamless, Secure, and Built to Last

At CBD Concrete, we approach every foundation addition project with detailed planning and expert execution:

1. Site Evaluation & Measurements

We assess the current foundation, soil stability, and proposed load-bearing requirements to design a compatible extension.

2. Formwork & Reinforcement

Matching the reinforcement (rebar) and slab thickness ensures that old and new concrete act as one.

3. Precision Pouring

Our team pours the new foundation using premium concrete that bonds effectively to the existing surface.

4. Curing & Quality Checks

We allow proper curing time and inspect the transition zones to prevent cracking or shifting over time.

The result? A seamless addition that looks and performs as if it were always there.
