Upgrading Your Slab/Foundations
troud Homes provides you with a ‘M’ class soil as a standard. We have found that 95% of other builders only provide you with a ‘S’ type soil which is only found to be about 2% of the building sites on the Sunshine Coast.
Below is an easy table to determine what the simple cost are to upgrade your soil for a standard Home up to 250m2.
For all ratings, it’s simply a matter of building a foundation that’s suitable for the soil type, and for the type, shape and size of house you want to build – an engineer will be able to figure out what’s most appropriate for your design and the site you’re building on.
Most Class ‘S’ sites will only need a basic reinforced slab while sites with other classifica-tions will require the slab to be stiffened. For slabs, this will require a series of cross beams in the slab – and sometimes piers too. This extra ‘stiffening’ helps to prevent the slab from bending and twisting.
For ‘highly’ and ‘extremely’ reactive sites and problem sites (i.e. Class H1, H2, E or P), a structural engineer will need to do a special assessment and advise on how to safely build a house without the risk of damage due to soil movement. Visit build.com.au to find out more.
