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.
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.
