EASILY DRIVE IN OR OUT
It's dependable Direct Drive system ensures you can drive the anchor forward or reverse for quick installation. Installs with a handheld ½" impact wrench (350 ft-lbs of torque recommended minimum). Use our hand auger tool if you prefer a manual installation.
-
Turn a week-long job into a weekend project.
-
Save money on labor, materials and time.
-
No sledge or jackhammers or heavy machinery.
-
Install in the morning and build in the afternoon.
*For floating or free-standing structures where freezing soil conditions exist.
HOW IT WORKS
DRIVE
Using a lightweight handheld ½" electric impact wrench and a 12mm six point socket, drive the auger deep into the soil.
TIGHTEN
Tighten the nut and compress the load plate against stop washer below the load plate.
ATTACH
Place the post saddle in the desired location. Tighten the upper nut to attach the saddle to the auger and load plate.
HOW DOES FROST AFFECT THE ANCHOR?
The Deck Foot Anchor™ does not heave up from the ground like a fence post that is literally popped out of the ground a little bit each year. The Deck Foot Anchor ™ remains anchored to the ground and moves with the soil as it expands up or settles down during freeze or thaw cycles.
Use only with freestanding decks, unless the soil does not freeze in your area.
WHAT IS TERRA-SHIFT™
Terra-Shift refers to our unique friction release system in the bracket that protects critical post to beam connections on your deck in the event of any seasonal soil movement.
If any uneven uplift forces are imposed on your footings, posts will slide up or down independently as needed to protect and preserve the post and beam joints from separating.
COMPRESSION LOAD
POST SADDLES TESTED FOR MAXIMUM LOADS
Independent compression load testing has confirmed that the 4x4 and 6x6 post saddles support up to a maximum of 15,000 lbs and 19,000 lbs respectively before failure.
The table data shows what the auger with a 3-¼" dia. blade by itself will support in two soil types.
This is far more than your soil will ever support. So the Deck Foot Anchor is not the weakest link. Your soil bearing capacity is the limiting factor.
UPLIFT
Pull out resistance (tension) from undisturbed soil varies by soil type and auger length. If you are building a project where known uplift data is required please see our Tension Test data for sandy or clay soils based on auger length. This is data taken from field testing by Intertek in a location in Colorado and is part of an extensive residential code compliance review program this is expected to be completed in the spring of 2022.
TERRA-SHIFT: A SHOCK ABSORBER THAT PROTECTS YOUR DECK
AUGERS AVAILABLE IN 24" OR 36" LENGTHS
Watch this demonstration of how the patented Terra-Shift system works to relieve stresses that may build up during seasonal changes and threaten the integrity of your deck structure.
Regardless of the harshness of your climate, the post to beam connections supporting your structure will remain strong and sturdy.
Use the 24" for most applications. Use the 36" auger when you want more wind uplift resistance or you are building on a slope. The auger length will make no difference how the Deck Foot will perform in frost as the above animation shows.
The deck will always be resting on the surface and will rise or descend marginally with the soil expansion and contraction. But it will always remain securely anchored to the ground.
LOW OR HIGH ELEVATION DECKS
GROUND LEVEL
You can build your deck with joists as low as 2"-3" above grade if you wish. Simply hang the joists from the perimeter joist. If you want to extend the deck beyond the footing, extend the side perimeter joists 6"-10" and fill with blocking joists along the length.
EASILY UP TO SIX FEET
With proper bracing in both directions from 6x6 posts to beams, you can make a six-foot high freestanding deck as solid as a rock. It's possible to go even higher but it is not intended to support decks at a second-floor elevation.
SECURELY ANCHORED: READY FOR HIGH WINDS
Decks supported by concrete blocks that rest on the surface are susceptible to uplift in high winds and have to be secured to the ground with a webbing of cables and ground spikes.
The Titan Deck Foot Anchor™ holds your footings securely to the ground. Almost 2/3 of the United States and parts of Canada are in high wind zones.
For maximum uplift resistance, consider using the 36" auger.
HOW MANY FOOTINGS DO I NEED?
The Rule of Thumb is 6'-0" apart for each footing. This corresponds to a design load of 50 psf and tributary areas over each footing of 36 sqft.
So the total load imposed on the soil below each footing would be a maximum of 1800 psf as the footing is just slightly larger than 1 sqft.
If you have a large deck where three or more beams are going to be used, consider adding one additional footing along the interior beam. This is because the tributary loads of any structure are always greatest in the middle.
USE OUR IMPACT SOCKETS
Our 12mm high impact six point socket is designed to grip the hexagon drive head without stripping no matter the load.
This tiny investment can save headaches on the job site. If you use a low quality twelve point socket that does not fit as well, you are more likely to strip the drive head while under maximum load.
