Secure Screw Piles is a Dartmouth, Nova Scotia contractor that installs screw piles and also offers rock drilling. Its site is branded for Halifax and says it works anywhere in Nova Scotia.
The site argues that its screw piles, which it distinguishes from helical piles, carry more load because of a larger bearing surface, install in any season with less equipment, and work in rocky or dense soils. It also cites lower noise and vibration, which it says suits urban and sensitive sites. It describes the piles as removable and reusable and mentions a 30 year product warranty. Pages cover what screw piles are, rock drilling, residential uses and a quote form.
Call 1 (902) 222-9232 or use the quote form. Because the site compares screw piles with helical piles in its own favor, ask for the pile dimensions, the load design behind them, how torque is recorded, and what the warranty covers.
