  • 2
    Torque recordsWill they log final installation torque for every pile and give you a copy?
  • 3

GAMCON Helical Piles & Waterproofing

GAMCON Helical Piles & Waterproofing is a construction company at 170 Evans Avenue in Toronto, Ontario. Its website describes a focus on helical piles, helical anchors and foundation waterproofing for Toronto buildings.

The site lists residential and commercial helical piles, helical anchors, interior and exterior basement waterproofing, and sump pump installation. GAMCON describes licensed and insured crews, solutions for difficult soil conditions, and a client-focused approach, and it offers a free consultation and an online quote request form. A portfolio page and a blog are also on the site.

GAMCON serves the Toronto area; call +1 416-888-4188 to request a quote. Because it offers both piles and waterproofing, ask whether the two scopes are priced and warranted separately. Also ask which pile size and helix configuration is proposed, whether installation torque is recorded and shared, who provides the engineering, how permits are handled, and what the written warranty covers.
