Our Shellcrete Installation Process
Shellcrete, also known as tabby, shell tabby, coquina, and washed shell concrete is the ultimate concrete surface for those who want to celebrate the calling to our beautiful Florida beaches. Installed using white Portland cement, sand and shell that is mined here on the west coast, it evokes walking on the sand, but no sharp shells or sand between the toes. Naturally cool surface that reflects the suns heat, it is a choice product for pool decks, patios, walks and even driveways.
01
Preparation
Substrate should be clean and free of cracks prior to installation. The surface should be prepared to increase adhesion by any of several means including chipping, scarifying, sandblasting to a minimum of 1/16 in. average depth. Alternatively, a new base slab should be finished with a coarse street broom.
02
Installation
ShellCrete topping is installed at a thickness of 5/8” to 3/4”. Intra-State recommends a minimum pitch of 1-1/2” in 10 feet. The matrix utilizes cement, sand, and shell and is placed within forms. The matrix is then seeded with additional shell which is floated just below the surface. Once setting begins, the top surface of the shell is exposed.
03
Control Joints
Control joints will be saw cut according to accepted industry standards. Joints in the existing substrate will be matched in the topping. Alternatively, metal stripping may be used as control joints to eliminate the saw kerf.
04
Finishing
After curing, the surface of the shell is lightly ground with a concrete wheel to remove sharp edges and burrs. It is normal to lose some of the surface shell during grinding due to vibration of the grinding wheel.
05
Cleaning
After grinding the surface is cleaned with a solution of muriatic acid and water to remove the cement film from the surface of the exposed shell.
06
Sealing
It is recommended to sealcoat the finished surface to help resist water and stains. A high solids solvent based acrylic sealer such as Conglaze, is the preferred product.
Benefits Of Shell Tabby Concrete
Intra-State Terrazzo & Concrete ‘Signature’ topping is a decorative mix of concrete and shell often referred to as “shellcrete” or “shell concrete.” It is used to create unique and aesthetically pleasing driveway, walkway, patio, and interior flooring surfaces.
Aesthetic Appeal
The embedded shells create a unique and elegant visually appealing surface with a natural, beach-like appearance. The white, ivory, and pearly hue colors of shells are intensified by a range of natural shades from pale to a slightly deeper hue exhibiting browns, tan, sandy and earthy vibrant notes. These shells are often smooth and glossy with distinct patterns and attractive metallic sheen. Their polished and shiny tone surface strikes iridescent array of brightness.
Durability
Crushed shells can enhance the durability of the concrete mix, making it resistant to wear, cracking, and erosion.
Traction
The textured surface provided by the shells can offer better traction, making it safer for walking and driving, especially in wet conditions.
Environmentally Friendly
Using seashells in the mix can be considered eco-friendly, as it repurposes natural materials and reduces the need for additional aggregates.
Cooling Effect
Shellcrete may reflect more sunlight and absorb less heat compared to traditional concrete, resulting in a cooler surface in hot weather.

Coquina Preparation
- Shell Selection: The first step involves a selection of suitable shells chosen for their natural appearance and durability. These shells are typically cleaned, crushed into smaller pieces, and sorted for uniformity.
- Concrete Mix: A standard concrete mix is prepared using cement, sand, and aggregate water. The specific mix ratio may vary based on the intended application outcome.
- Incorporating Shells: Once the concrete mix is ready, the crushed shells are added to it. The shells added can vary depending on the desired appearance, texture, and density which make up a portion of the aggregate in the concrete mix.
- Mixing and Placement: The shells are thoroughly mixed with the concrete mixture until they are evenly distributed. Then, the mix is poured or placed onto the prepared surface, such as the driveway, walkway, patio, or interior flooring.
- Sealant: A sealant is applied to create a protective barrier on the surface of the driveway that shields it from the damaging effects of weather and ultraviolet (UV) rays enhancing the durability withstanding the weight of vehicles, foot traffic, and other loads. The sealant intensifies the colors and preserves the beauty making it easier to maintain.
