Hess is the leading supplier of pumice products to industry in the world. Here's why:
The quality of Hess Pumice is recognized as superior to any U.S. source, with a hardness and purity equal or superior to any source in the world.
We process over 30 standard grades and more than 300 custom grades.
Hess ships pumice worldwide—by the freight car, ocean container, pallet, or single bag.
Hess Pumice Products was founded on good fortune and nurtured by hard work and optimism.
Hess crushes and processes pumice for use in a wide and amazing variety of products and industries. Being chemically inert and crystalline silica-free, pumice is both safe to use and safe for the environment.
Pumice concrete has several exciting advantages over conventional concrete in many construction applications. And our pumice pozzolans—HessPozz and Hess UltraPozz—have sparked the renaissance of pumice pozzolan for high-performance concrete formulations.
Our DS-200 and DS-325 lightweight aggregates are specifically engineered for use in the oil well cementing industry. They provide a superior composite of lightweight slurry, high-strength concrete and a low permeability shield.
Hess Pumice is used extensively worldwide for critical surface finishing processes—for glass, metal, wood, leather, and plastics.
The near-white color of our pumice, coupled with its chemically and environmentally inert nature makes it an appealing choice as a filler and extender.
U.S. Grout, a division of Hess, produces an ultra-fine cementitious grout composed of a finely ground mixture of Portland cement, pumice and dispersant that will fill tiny cracks.
The foamy structure and near-white purity of Hess Pumice makes it ideal to capture and hold cyanobacterial toxins and other impurities found in fouled drinking water.
When used for purposes of blast mitigation, cellular solids, like pumice, collapse at a cellular level beneath the force of the blast, absorbing much of the blast energy and effectively containing the damage.
Because of its highly porous nature, pumice holds water and air—both critical to well-conditioned, aerated soils.
Pumice is finding its way into more and more applications and industries that have traditionally relied on other materials.
