Re: Company Name Change
Dear valued Client,
As you may know, Alston Associates has been owned by Terrapex Environmental Ltd. (Terrapex)
since 2010. This letter serves to advise you that effective April 1, 2019, Alston will officially be
using our parent company’s name Terrapex.
There has been no change in management and we will be providing the same geotechnical
services on which we have built our reputation in the industry. Our commitment to our clients will
remain unchanged. Along with geotechnical services, Terrapex provides consulting services in
environmental, hydrogeological and building science fields.
Our email addresses will change from alston.ca to terrapex.com, and we will start using
Terrapex’s phone no. (416) 245-0011, although our 905 number will remain active for another
Thank you for being one of our valued clients.
TERRAPEX ENVIRONMENTAL LTD.

Vice President, Geotechnical Services
