What type of foundation is required?

BOXA uses a rapid install, instant load-bearing galvanised steel micro-pile footing system supporting an optimised and  treated engineered timber subframe. Minimal environmental footprint with a clean, light and aesthetic finish No ground works or digging / trenching, no cement, no water, no waste, no curing time.

BOXA uses a rapid install, instant load-bearing galvanised steel micro-pile footing system supporting an optimised and  treated engineered timber subframe. Minimal environmental footprint with a clean, light and aesthetic finish No ground works or digging / trenching, no cement, no water, no waste, no curing time. Ideal for sandy, muddy, clay,  calcrete, dolomitic ground conditions. For rocky ground, a chemical anchor system is employed together with the micro pile footings. A galvanised steel stub column and levelling system supports the engineered and treated timber  (Eucalyptus) subframe. Additional lateral micropiles are fixed directly to the subframe to minimise any deflection and  vibrations, and ensure lateral stability. Where elevation of floors exceeds 1.0m above ground level a stainless steel  cable cross-bracing system is also installed to further ensure stability.  

Once the project is confirmed and prior to completion of the design process, Sustainabuild will attend site and  undertake a thorough assessment of the access, topography and ground conditions, including DCP tests. If a Geotech report of the site is available this will also assist in validating the ground conditions and pile lengths in accordance with  the engineering parameters of the micro-pile footing system.  

The bearing capacity of each footing ranges from 3,000 – 9,000 kg, depending on the ground composition. BOXA  installations typically have a dead load in the range of 250-300 kg per sqm, and a footing distribution of 1 per 7-10 sqm,  depending on the typology. Therefore the dead load of BOXA installations ranges from 1,750 – 3,000 kg per footing,  well below or within the lowest end of the range of the footing bearing capacity. A more primary concern is the live uplift loads in the event of high winds, which is where the footings really perform given the lengths of steel micro-piles in the  ground.
