Grassland Screw Piles is a screw pile installer in Winnipeg, Manitoba, owned by Rob Wiebe. The site says Rob has more than 30 years of construction experience and a long interest in machinery and hydraulics that led him to start the business.
The company installs Almita screw piles, which it describes as CCMC certified and backed by a team of engineers. The site explains how screw piles work in sandy, clay and marshy soils, and lists applications that include deck construction. Its pages cover screw piles, helical piles and deck building.
Contact the company through the site or at +1204-999-0758. Ask for the CCMC evaluation documents for the pile model proposed, how installation depth and torque are verified, and whether an engineer's plan is supplied for the building permit. These are general suggestions, not statements about this company's practice.
