Winnipeg Region
Site and Soil Evaluation Field Day @ Winnipeg Region

MOWMA/OWSIM are hosting a Site & Soils Evaluation Field Day in the Winnipeg area on October 13, 2018. This practical training day is a great opportunity to get hands-on experience evaluating a site, as well as practicing hand texturing and sampling. Installers who have recently completed their certification training will be able to take their new knowledge and apply it on-site. Experienced designers and installers should also consider this opportunity to continue their education.

Please contact the MOWMA/OWSIM office with any questions you may have.

The expected outcomes for this training are listed below, and a registration form is available. You may register for this hands-on training by fax, email, or online. Please contact the association office with any questions you may have.
