Shellcrete – Intra-State Terrazzo & Concrete ‘Signature’.
Character with Elegance!
Intra-State Terrazzo & Concrete ‘Signature’ topping is a decorative mix of concrete and shell often referred to as "shellcrete" or "shell concrete." It creates unique and aesthetically pleasing driveways, walkways, patios, and interior flooring surfaces. This combination involves embedding shells into a traditional concrete mix.

Here's a general description of how this mixture is prepared and its benefits:
- 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.
Benefits of Using Shell Topping:
- 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 an 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.
