The Castia Stone advantage

The advantages are many. We give you a wide selection of accessories, including fluted columns, and our designs were created to reflect an old-world elegance. Castia Stone is easy-to-install, environmentally friendly, and protects your home with a unique rainscreen technology.

Manufactured stone veneer

All Castia Stone products are manufactured with high-strength concrete, aggregate, sand and water. The stone is processed through an automated dispersing and mixing system and then poured into forms. Once the forms are filled and brackets are installed, the stone is cured in an environment where humidity and temperature are constantly controlled. This intense curing cycle ensures the consistency of quality, durability and color of all Castia Stone products.

Rainscreen technology

The Castia Stone “rainscreen” design creates a continuous 1/2” airspace between the stone siding and the structure of your home or building, which allows ventilation and drainage to occur. This means you can say goodbye to trapped moisture, dry rot and mold. Castia Stone quality is proven through product development and testing.

Specially engineered brackets are used to hang Castia Stone and create the continuous ½” airspace. These brackets are embedded into the concrete before curing and are designed to withstand average pullout strengths in excess of 200 pounds.

Venting and draining

One of the most important features of the Castia Stone siding system is the rainscreen design which allows proper moisture drainage and ventilation. When installed properly, the Castia Stone siding system will deflect any moisture directed at the building. If moisture does penetrate the siding, it will be channeled directly outward because of Castia Stone’s innovative bracketing system that creates the continuous ½” gap between the siding and the actual structure. This air space prevents trapped moisture, which may lead to dry rot and mold.

Trapped moisture is the leading cause of building failure, and other products like stucco, wood siding, natural stone and other pre-cast products do not feature this space for venting and draining. Moisture may not only enter from the outside, but condensation from inside may also migrate from the building interior and become trapped between the structure and exterior façade. The Castia Stone siding system allows any moisture that travels through the walls to vent outwards.

Pre-cast stone has been used in construction for hundreds of years with proven strength and durability. It is manufactured to withstand the abuse of natural elements such as rain, hail and ultraviolet rays.

Mortar-free system with expansion joints

Castia Stone is one of only a few masonry systems that do not require mortar. Instead of using mortar to support the product, Castia Stone employs a cast-in-place bracket system that is screwed to the wall. To produce a mortared appearance, a commercial grade polyurethane or silicone caulking is applied to all seams and then silica sand is spread over the caulking. This same caulking is used in many commercial buildings as expansion joints.
Because tiles are individually supported, the Castia Stone system is more resistant to seismic movement than any other masonry product. The Castia Stone system is beneficial to new construction because homes or buildings can settle without the risk of cracking mortar joints that may lead to moisture damage.

Determination of anticipated joint movement

When taking into consideration the amount of movement a specific joint will endure, we can assume that temperature will account for the majority of that movement. Settling of new construction and seismic activity will also account for some movement. Since Castia Stone is manufactured with light weight concrete, the coefficient of linear expansion used to determine the maximum movement a joint will endure is less than standard weight concrete. A standard tile will expand less than 0.01 inch with a 100 degree temperature variation. The Castia Stone system is designed to allow for up to 50% movement of joint space, if necessary for settlement and seismic activity.

Stainless steel screws

All Castia Stone products are installed using stainless steel screws. The pull-out strength of a screw is much higher than that of a nail or a staple, and these screws are engineered to support a load 20 times more than the weight of each Castia Stone piece that they are holding.


Sand is used to coat the caulking and creates a mortared appearance.


Castia Stone weighs about the same as traditional stucco. The average weight of the siding is 7lbs per square foot. This allows Castia Stone to be installed on most structures without making changes to the foundation or adding reinforcing support.

Color throughout

All Castia Stone products are mixed with naturally occurring iron oxide colors which allow for a natural variance in color. While UV rays will slightly affect any color, this color throughout system allows the product to stand up to harsh rays of the sun.

Year-round installation

Unlike some masonry products, Castia Stone can be installed regardless of weather and temperature conditions. Contact your local Castia Stone distributor to get a list of certified installers in your area.

Many designs to choose from

Available in a variety of colors, textures, and richly crafted moldings, Castia Stone offers unlimited design possibilities to enhance many architectural styles.

Environmentally conscious

Castia Stone is made up of concrete consisting of cement, aggregate, sand, coloring and water, unlike many exterior siding products it does not impact our forests. Pre-cast concrete is formed through a natural chemical reaction.


Castia Stone is priced competitively with alternatives such as brick, stucco and cultured stone. It is less expensive than natural stone. Get an estimate for your project.

Low maintenance

Remove dirt with water. Castia Stone requires no painting because the color is in the mix. If necessary, individual tiles can be replaced easily.


Castia Stone is backed by a lifetime limited warranty.
