What is Engineered Cast Stone?

Engineered Cast Stone is a unique mixture of premium cements, crushed limestone, colorfast pigments and proprietary admixtures. The cast element is hand etched to expose internal aggregate while preserving fine details and sharp edges. The resulting stone-like material resembles natural limestone but is superior to natural stone in strength, density, uniformity and durability. Our Engineered Cast Stone architectural elements also surpass the surface quality and appearance of traditional cast stone. Engineered Cast Stone may be reinforced with steel or polymer rebar and mineral fibers.

Engineered Cast Stone is available in 12 standard colors or custom colors which are pigmented throughout the casting. Natural ingredients may result in minor variations of color uniformity. Custom colors are also available, we can match most any stone color. Please provide us with a color specification or a color sample. We can create a color sample and send it to you for your approval.

Engineered Cast Stone elements are also available with an acrylic primer coating suitable for topcoat painting at the jobsite. Stainless steel embedded anchors are typically provided to assist with mounting Engineered Cast Stone elements to structural substrate. Large cast elements contain stainless steel embedded lifting hardware.

Architectural medallions, frieze bands, sculpted panels, and other cast elements are available in Engineered Cast Stone or GFRC. Architectural Grilles are only available in Mineral-Polymer Composite.

How is Engineered Cast Stone better?

Engineered Cast Stone is better than natural stone because it is uniformly engineered and not subject to the occasional random defects found in natural stone. Engineered Cast Stone is also made from sustainable materials and is easier to fabricate than natural stone and therefore less expensive.

Engineered Cast Stone is superior to polymer stucco EIFS carvings because of the quality of its highly detailed surface texture and details. Engineered Cast Stone is also much stronger than EIFS systems and not as readily damaged by storm events or environmental challenges. Engineered Cast Stone is heavier than EIFS carvings and therefore needs more substantial support. Conditions that require an ornament to be less heavy than one made from Engineered Cast Stone can benefit from Pineapple Grove Designs’ light weight material alternatives TechStone and PolymerStone.

Engineered Cast Stone is extremely durable. It is uniformly engineered for strength. Engineered Cast Stone colors are uniform throughout the matrix; not surface coated like some other manufactured cast stone. Engineered Cast Stone is carefully finished with a consistent surface appearance, finely detailed features, and straightforward installation methods.

Mineral-Polymer Composite is earth friendly

Mineral-Polymer Composite is composed of sustainable and recycled metals and minerals and is fabricated using environmentally responsible methods and procedures. The raw ingredients are composed of over 50% post industrial and post consumer material.

Mineral-Polymer Composite items are engineered strong enough to reduce the need for excessive packaging material. They are also sufficiently durable and can outlast the lifecycle of the project where they are installed thereby eliminating the environmental cost of their replacement. They are fabricated on demand and thus do not require resources to inventory, maintain or replace spoilage. Mineral-Polymer Composite items are shipped directly from the manufacturing facility to the jobsite greatly reducing energy consumed in typical distribution shipping and handling. Mineral-Polymer Composite material generates no solid waste as overruns and blemished or otherwise unusable items are ground up and reused to fabricate new Mineral-Polymer Composite items.

Elements: Custom Elements

What is HDU?

High Density Urethane (HDU) is a versatile, lightweight, and durable synthetic material commonly used in various applications, particularly in signage, architectural details, and decorative elements. It is made from urethane foam, which is manufactured through a process that results in a dense, closed-cell structure, making it resistant to moisture, rot, and insects.It can be used in a variety of finishes and textures, and is often used in architectural accents, decorative moldings, and plaques, as well as custom signage.Overall, HDU is a popular choice for creating detailed, long-lasting decorative and functional elements.

Custom Architectural Elements, sculpted panels, and other decorative elements are available in HDU.

How is HDU better?
HDU is highly durable and can withstand outdoor environments without cracking, warping, or deteriorating over time, even in harsh weather. It can be easily cut, carved, sanded, and painted, making it an excellent alternative to traditional materials like wood or stone for detailed designs. Despite its density, HDU is much lighter than wood or metal, making it easier to handle and install. HDU is non-porous and moisture-resistant, which makes it ideal for outdoor use, especially for signage or decorative elements that are exposed to the elements.
‍
HDU is earth friendly
HDU can be considered earth-friendly for several reasons, particularly due to its sustainable production process and its long-lasting, eco-friendly properties. HDU is chemically inert and does not release harmful gases or toxins into the environment, making it safer to use and less impactful on the ecosystem compared to other materials like treated wood or certain plastics.

Because HDU is lightweight, it requires less energy to transport compared to heavier materials like wood or metal, contributing to lower fuel consumption and reduced emissions during shipping. This helps lower the overall carbon footprint of the material.

HDU’s durability means it does not need to be replaced or repaired as frequently as materials like wood, reducing the consumption of resources over time. Its resistance to moisture, rot, and insects minimizes the need for harsh chemical treatments, paints, or frequent maintenance.

These attributes make HDU a more sustainable option for projects requiring long-lasting, versatile materials, especially for those looking to reduce environmental impact.
