Pumice is an extremely light, highly porous extrusive volcanic rock, formed through the rapid cooling of air-pocketed lava. In fact, some pumice is so light that it can float on water. Although pumice is often light in color as well, depending on its mineral makeup, it can vary from white to pink to gray to black.

Kaolin Clay

Kaolin Clay Powder is a 100% pure and natural clay made up of the mineral Kaolinite. Also known as White Clay, can be used with water or any other natural ingredients and works efficiently to tackle most of the common skin related issues. Kaolin clay mask for pores helps in shrinking large and open pores, powerfully fights off blemishes and maintains skin elasticity.


Baryte, barite or barytes is a mineral consisting of barium sulfate. Baryte is generally white or colorless, and is the main source of the element barium. The baryte group consists of baryte, celestine, anglesite, and anhydrite.


Sodium Bentonite has high absorbency with clumping attributes while also being useful as both a soil and pond sealant. It is considered a safe, natural, nontoxic and inexpensive treatment for porous soils. Its swelling capacity gives Sodium Bentonite the ability to bond with soil and create an impenetrable barrier.


Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.


Zeolites are widely used as catalysts and sorbents. Their well-defined pore formation and adaptable acidity make them highly active in a variety of reactions. Research and development of many biochemical and biomedical applications of zeolite, especially the naturally occurring species Hylandite, Clinoptilolite and Chabazite are ongoing.


Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls, and hence is denser. The difference is probably the result of lower magma viscosity, allowing rapid volatile diffusion, bubble growth, coalescence, and bursting. It is typically dark in color (generally dark brown, black or purplish-red), and basaltic in composition.


Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO₄·2H₂O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.


Gilsonite is a naturally occurring, solid, black, lightweight organic material that originates from the solidification of petroleum.


Attapulgite is a magnesium aluminum silicate clay of very fine particle size. Unlike bentonite (or montmorillonite) attapulgite crystals are needle shaped (acicular) rather than flat or flake-like. Like bentonite they disperse well to thicken, suspend and gel suspensions without flocculation problems.

About Us

Atrium Lightweight Materials Inc.

Atrium Lightweight Materials Inc is your nexus point between raw mineral materials and the facilitation of their use in industrial applications. It is the specific attributes of a mineral which determines how it can be utilized or blended sometimes with other minerals sourced from around the world. Many companies have inefficiencies or input requirements that require a unique mineral solution. Certain regions of the world have resources which can offer exceptional added value when utilized by a company in a different geographical context.

We began as a supplier of lightweight aggregates throughout Alberta and Western Canada. Due to the extreme frozen temperatures underground utilities needed to be placed 2 to 3 meters below the grade of the surface to stay below the frostline in winter. This is a considerable increase in cost relative to a standard shallow utility structure which is near the surface. Surrounding the pipe with an expanded shale, which has a lower thermal conductivity, frost protection is created to facilitate the implementation of shallow utilities that will no longer freeze during the winter. It also offers drainage of excess water around or near the pipe. We are the exclusive supplier of Aggrelite™ and Granulite™ lightweight expanded shale which is used in various geotechnical applications involving underground pipe insulation for shallow utility applications. These materials are also useful as a structural fill over poor soils & marshlands.
