Engineered Cast Stone | Medallions & Friezes • Masonry Inserts • Custom Elements

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.

Engineered Cast Stone is earth friendly

Engineered Cast Stone is composed of low CO2 cements, sustainable and recycled aggregates, and is fabricated using environmentally responsible methods and procedures. The raw ingredients are composed of over 50% post-industrial and post-consumer material. Quarried aggregates are sourced within 200 miles of the final production facility.

Mineral-Polymer Composite | Grilles • Custom Elements

What is Mineral-Polymer Composite?

Mineral-Polymer Composite is a unique mixture of polymer cements, crushed limestone, mineral fiber and proprietary admixtures. The cast element has a smooth finish with fine details and sharp edges. The resulting casting has exceptional flexural strength and durability. Our Mineral-Polymer Composite elements may also be reinforced with steel or polymer rebar.

Mineral-Polymer Composite elements are available primed with a durable industrial acrylic topcoat painting.

Stainless steel embedded anchors are typically provided to assist with mounting Mineral-Polymer Composite elements to structural substrate. Large elements contain stainless steel embedded lifting hardware.

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

How is Mineral-Polymer Composite better?

Mineral-Polymer Composite is uniformly engineered and fabricated in a process that consumes and releases substantially less carbon than conventional metal production and is not subject to oxidation and corrosion that typically attacks architectural metal. Mineral-Polymer Composite is also made from sustainable materials and is easier to fabricate, install and maintain and therefore is less expensive.

Mineral-Polymer Composite is extremely durable. It is uniformly engineered for strength. The finishes are long lasting and resistant to deterioration and color fading caused by weather, sunlight or most environmental conditions. Mineral-Polymer Composite products are uniform throughout the matrix; not surface coated like some other manufactured cast stone. Mineral-Polymer Composite is carefully finished with 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.

GFRC | Custom Elements

What is GFRC?

GFRC is a unique mixture of premium cements, crushed limestone, acrylic polymer, mineral fibers and proprietary admixtures. The cast element has a smooth finish with fine details and sharp edges. The resulting stone-like material is superior to traditional cast stone in flexural strength and durability. Our GFRC elements may also be reinforced with steel or polymer rebar.

GFRC is available in natural cement white finish. Items 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 GFRC or Engineered Cast Stone. Architectural Grilles are only available in Mineral-Polymer Composite.
