Client Testimonials

Sean J.

Great service and attention to detail. Had a large area of shell crete put down at our house on the key and Intrastate did a very nice job. I had a lot of questions and they were patient and answered them all prior. Plus their price beat others. Plus they cleaned up and left the area in good condition as that is a pet peeve. Pros!

Roni B.

Pavers were installed in my lanai planter surround. The plants were carefully removed with a minimal of soil getting into the pool. Both the office staff and the installers were personable and professional. The estimate was clear and fair. The job was done as indicated and beyond. I am new to Florida and very pleased to find a company of integrity.

Chris M.

I called to ask about getting Terrazo, Epoxy, or Stained concrete flooring in my house. The gentleman I spoke with was extremely knowledgeable and quickly helped me determine the pros and cons of each option and the relative estimated costs. The conversation only lasted 20 minutes or less but amount of no nonsense clear information conveyed was 10 times more than I get usually. Ultimately we decided none of these options would be a good fit for our home but if your considering any of them I cannot recommend strongly enough that you give them a call as they will help you quickly figure out which, if any, of these options is good or you.

Robert A.

As a custom homebuilder since 1986 it is important to surround yourself with quality subcontractors. Intrastate is a quality subcontractor and offers a service that our high-end clients desire. Intrastate was on time, responsive and outstanding finished work makes it easy for us as the general contractor. Their ability to meet with homeowners also helps us as a general contractor. I would recommend Intrastate to other builders.

Our Shellcrete Installation Process

Shellcrete 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.



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.



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.


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.



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.




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.



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 Shellcrete

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.


Crushed shells can enhance the durability of the concrete mix, making it resistant to wear, cracking, and erosion.


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.

Shellcrete 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.
