Why the Winslow Geo Anchor
• Today’s engineers and contractors place tremendous value on performance, cost, and environmentally friendly technology, and want to provide each of those elements to their customers.
• Thousands of Winslow Geo Anchors have been installed in foundations during the past 20 years without one structural failure or callback -- including five major pool projects in the past two years.
• In addition to an unparalleled record of performance, it often costs 15- 20% less than drilled concrete piers. And, since steel has a much smaller C02 footprint than concrete, it’s a far ‘greener’ solution too.
Bottom line: we’re passionate about delivering this product.

How the Winslow Geo Anchor delivers superior performance for less money and is ‘green’
• Each anchor is custom fabricated to exact project specs by certified welders using a-grade materials at a controlled facility.
• Installed anchors are tested to ensure load capacity – a check not done with drilled concrete piers.
• Installs in minutes vs. days, in any weather, and produces no spoils/off-haul. Cost per ft. is often 15- 20% less than drilled concrete piers.
• The production, transportation, and installation of steel anchors has a significantly smaller CO2 footprint than drilled concrete piers.

Additional Benefits
The Winslow Geo Anchor also provided benefits in:
• Ease of construction: Anchors were ‘done’ when installed (avg. eight minutes per), vs. 3 days for piers (drill, 1.5 days, off haul spoils, .5 days, set caissons/pour, 1 day).
• Logistics: An array of trucks required for drilled piers vs. one tractor for anchors (no mixers or pump trucks – and accompanying neighborhood congestion – required).
• Safety issues: Amplified with the drilled piers solution (18 holes 16” diameter x 15’ deep introduces dangerous environment for humans and/or animals).
• Documentation: Each anchor installed is observed by a geotechnical engineer to ensure torque and depth requirements – checks not done with drilled piers.

Corrosion Protection
• Every Winslow Geo Anchor is coated based upon project specific soil conditions (Resistivity, pH, Sulfates, Chlorides), and appropriate corrosion protection applied (epoxy, galvanization, cathodic).
• Consultation provided by Carrie Howell, recognized leader in corrosion engineering in construction industry.
• Technical paper: “Corrosion of Helical Anchors in Soils” (2008, Dr. Tom Bragg, Director, Special Projects, Best Base Foundation Systems. Available at: www.thebestbase.com).
