AAS provides three different product materials for architectural stone applications:
- Dry vibrant-tamp cast stone
- Wet-pour architectural precast concrete
- Architectural GFRC (Glass Fiber Reinforced Concrete
All three products provide considerable design flexibility and durability compared to natural stone products such as limestone. The project specific detailed engineering and custom fabrication simplify the installation while also achieving superior design aesthetic.
- While cast stone and architectural precast use different casting technique, the two products have similar structural properties. AAS has track record for developing custom stone design, using either of the two products, or combining the two products as required to achieve intended design objective for a project cost-effectively.
- Architectural GFRC panels are only 3/4″ thick, and yet have very good strength to weight ratio, providing unique advantages over other casting techniques. The AAS GFRC product material is much more durable compared to other thin veneer panels. GFRC can match look of other architectural stone products as well as limestone. The GFRC panels cost relatively more than other architectural stone products, however it has specific advantages with less structural support requirement and simpler installation.

Dry Vibrant-tamp Cast Stone
The dry vibrant-tamp fabrication technique allows flexibility to shape both sides of stone panels even when shape or design of stone panels is highly complex. This is offers more flexibility to realize virtually any design shape. The manufacturing process also opens up design freedom to emulate looks of variety of different stone types including natural limestone. AAS has extensive track record with projects where manufactured stone matched custom color and finish of natural stone samples.
Cast stone is very cost-effective compared to natural limestone. Learn more about the vibrant-tamp casting process in this video:
> PROJECT EXAMPLE: LA Sports HOF: Complex geometry, large size stone pieces for interior stone veneer that achieved architect’s design vision of complex channels of nearly Cane River.
> PROJECT EXAMPLE: Houston Market Square – cast stone cladding combined applications for stone façade, pilasters, coping, cornices and bandings – custom color emulating lueders limestone.
Dry cast-stone has comparable structural properties to wet-pour precast stone.
Wet-pour Architectural Precast Concrete Stone
The wet-pour manufacturing technique allows flexibility to embed structural steel or other reinforcements making it more suitable for load bearing architectural elements. In general, architectural precast concrete can achieve longer span or length for individual stone pieces.
Different finishes can be achieved on architectural precast stone using post cure treatments such as acid etching, sand-blasting and other techniques. On heavy use application areas such as stair treads, architectural precast can retain the surface finishing of the stone for very long time spans.
Architectural GFRC (Glass Fiber Reinforced Concrete)
The architectural GFRC also known as light weight concrete offers look and finish, as well as longevity and reliability of other stone products with much lighter weight. The proprietary manufacturing technique enables very high strength to weight ratio for the GFRC panels.
While cost of architectural GFRC can be more than other cast stone products, it can also help with less structural support requirements and simplified installation equipment requirements.
COMBINING DIFFERENT PRODUCTS FOR A SPECIFIC PROJECT
Customers have options to combine any of the three product materials with seamless matching of color and finish.
