Starting Monday, July 6, entry to our facility will be open for customers. However the following guidelines must be followed:

  • Only 1 person permitted at a time, no exceptions.

  • Hand sanitizing at entry is mandatory.
  • No admittance to office or washroom accessibility.
  • Debit or credit cards - no cash accepted.

Entry is for the purchase of supplies only. Technical assistance or inquiries are to be submitted via email or phone. Curb side pickup remains available if this is preferred rather than plant entry.

Observance of these conditions is essential for the continued health and safety of our employees and our customers.

Thank you for your understanding and continued support.

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).
