Precast Decorative Concrete and Pumice

Concrete is a crucial component of modern civilization...it forms the utilitarian backbone of our physical infrastructure. Concrete also finds utility in the expressive details that beautify and add interest to that infrastructure. When formulated, mixed, and poured correctly, it endures for centuries.

Manufactured Stone and Brick Veneers

Exterior and interior finishes of stone and brick are persistently popular and classically beautiful, lending interest and character in the form of texture, shape, depth, and color. A stone or brick finish is also extremely durable and requires little care. But materials and installation costs—especially for dressed native stone—can be quite expensive.

Weight too, is an issue. Stone and brick finishes require beefed-up structural supports and sturdier foundations to carry the additional load.

The construction materials industry responded to these often-prohibitive costs by developing cast stone and brick products made from lightweight pumice concrete—veneers that look and function like the real thing, but with significant advantages in materials costs, installation costs, and weight.

Pumice is the ideal aggregate for these decorative concrete products: it can be sized for any needed mold shape, providing bulk and strength, yet results in an impressive, lightweight look-alike that can be used as an interior or exterior finish without additional supporting ledges.

Fine-grained pumice also lends impressive pozzolanic qualities to the concrete mix, amplifying strength and durability.

Color is critical in manufactured stone and brick products, and the consistent clean near-white color of Hess pumice means the color of the molded stone or brick starts and finishes rich and vibrant.

The same intense demands of color purity, durability, strength, load-reduction and portability hold true for decorative cast concrete products.

GFRC Panels and Products

Glass fiber reinforced concrete (GFRC) products apply lightweight mold-cast concrete on a grand scale, resulting in panels that beautifully skin and protect large structures and finish interior walls and ceilings with fascinating, enduring detail. For such surfacing panels, the balance between weight, strength, and durability is a delicate one—bright, hard, lightweight Hess pumice aggregate and superfine Hess Ultrapozz (pumice pozzolan) make it all work to impressive advantage.

Case in point: Nippon Electric Glass (Japan) and NEG America, world-spanning supplier of materials and support to GFRC panel manufacturers, stocks and distributes Hess UltraPozz.

Decorative Concrete Applications

Pumice concrete is molded and formed into statuary, ornate exterior furniture, counter tops, fence panels, fireplace surrounds and more. It is the perfect choice for casting cornices, columns, copings and other architectural elements (especially in restoration work). And the same intense demands of color purity, durability, strength, load-reduction and portability hold true for all these products and applications as well—demands that our bright, pure, carefully refined pumice meet or exceed.

Lightweight Concrete Strength

Strength and less weight can co-exist effectively. For those casting and shipping precast concrete products, decreasing per-piece weight while retaining strength and performance means significant savings in shipping costs. Hess Pumice’s expertise in strong, lightweight pumice-concrete mix designs for molded concrete products could be just what you need to increase your reach — to competitively ship your precast concrete products farther and more effeciently.

pantheon dome made with pumice concrete Completed in 126 AD, the enduring Pantheon in Rome, and in particular the dome, was constructed with pumice aggregate and pumice pozzolan-enhanced concrete. Almost 2000 years later, the Pantheon is still the world’s largest unreinforced concrete dome.
