Outdoor pieces are cast in a stained
grey cement and aggregate mix or an off-white cement and crushed marble mix.
In order to produce a top-quality concrete that will not break down in the winter,
two additives are used: A) Air Entraining: This puts microscopic bubbles in the concrete
that contract and expand during the freeze/thaw cycle, and B) Water Reducing Plasticizers: Less water in the mix means a higher
strength.
Our concrete can stay outside all year round, although bowls, fountains, and statues
that collect water will crack when said water freezes and expands (true of all
concrete). Our products have been exposed to the harsh conditions of the Canadian
prairie's winters for some years now, without any significant problems.
