Important Notice

Plainsman Clays Ltd. will be closed to public access starting Thursday March 19. We will keep the doors closed (no exceptions), but continue to take and fill orders via phone (credit card only accepted) and e-mail. Pick up orders will be placed on at the front of the building, however we will be unable to assist in any loading. These measures allow us to limit contact with customers and minimize any risk with regards to the COVID-19 virus.

We can be reached by phone at 403-527-8535, fax 403-527-7508 and via email at

Thank you for your understanding during this difficult time.

Plainsman can supply clay fillers with a wide range of physical properties, colors, textures, particle sizes and shapes, plasticities and water permeabilities. Our process also enables us to make much coarser particle sizes with consistent particle size distributions than what are commonly available elsewhere.


We have light and dark cream, light and dark grey, light and dark brown, light and dark red, maroon, greenish and rust colored clay, silt and sand powders.

Particle size/shape

We have silty and sandy materials as well as fine and very fine powders. Particle shapes ranges from flat sub-micron particles to large angular and rounded ones.


We have permeable powders that allow water to pass through very freely and, conversely, completely impermeable ones (that swell on contact with water and completely block further passage). When these impermeable powders are incorporated in suspensions they help hold onto the water to provide resistance to water loss and dry-out.


Plastic clay powders have very large total particle surface areas and have surface chemistries that have an affinity for water. This makes them excellent to act as both fillers and at the same time suspend non-dissolved particles (this suspension happens because the particles have charged surfaces and oppositely-charged edges that produces in a house-of-cards aqueous structure that envelopes the non-clay particles).
