Deck Foundations – Using Helical Piers

Deck Foundations – Using Helical Piers as Your Solution

We have all heard the old adage “It is only as strong  as its foundation”. This particularly true with your home and the additions that  you make to it. When adding a deck to your home, using helical anchors for its foundation gives you the security of a deep foundation with the ease of installing a helical soil screw.

This same technique is now being used in deck construction for many reasons including ease of installation, all weather installation and simply economics.

The old fashioned method of buying extra long and expensive deck posts and concrete is being replaced with simple steel helicalfoundations. Helical foundations are a steel shaft  that has a helix shaped flight welded to its leading end that uses installation torque as an indication of capacity. These helical anchors come in many sizes, configurations and  lengths. The anchor is turned into the soil via a hydraulic gear motor that is  either attached to a small machine, such as a skid steer or even installed by  specialized hand held equipment. The gear motor slowly turns the helix into the  soil until it is significantly embedded past the upper active regions of soil.  After installation a simple steel bracket is attached between the steel  foundation and the deck posts.

Gone are the days when we need to excavate soils and fight the placement of  deck posts. If a helical anchor is installed in the wrong place they can simply  be reversed out of the soil and placed in the correct position without having to back fill the hole. Gone also is the need for concrete mixing and filling around  posts. The helical piles install with minimal disturbance to the soil so back filling and concrete is not required. And lastly, gone are the days of  watching your buried deck posts rot away due to water and termites.

On your next deck project save on lumber, concrete and installation costs by using helical anchors as the preferred method of foundation building.You will  now have the confidence that your new wood deck with last for many backyard barbecues and neighborhood gatherings for friends and family.
