Piling Technology

A strong foundation.

Our granny flat builders engineering principles are based on piling technology using a combination of skin friction and bearing. Because it is a non-displacement pile, the system can be used in any penetrable soil-sands, silts, clays, small gravels and even rock, as well as in all wind categories.

Installation times range from 10 minutes to 30 minutes, depending on which size Surefoot you are using. Adjustments to plumb and level after your foundation is installed makes it an easy to use system. Surefoot has instant bearing capacity in every direction so works can continue that same day.

Footings keep evolving to take advantage of additional means of withstanding loads. Our system is engineered to Australian Standards and is Building Code of Australia compliant with load capacities up to 360kN (36 tonne). Surefoot’s hybrid system can handle a large bending moment load which means that it can be used for just about any application.

Floor Systems

Surefoot Foundations.

Our Granny Flats and Gardens Studios are constructed using a fully galvanised welded floor system. We use 100 x 50 mm joists, and 150 mm x 50 mm bearers in steel with a thickness of 2 mm. Unlike timber, our floor and foundation system is not susceptible to shrinking and movement. This system allows us to screw fix every floor sheet securely eliminating any squeaking . Our subfloor system and the surefoot foundation, give a long term maintenance free period for the life of your studio.
