A Lot Classification (also known as a site classification) is a site-specific
testing regime performed using a utility mounted drill rig. We drill down to the
required depth as determined in the Australian Standards to give valuable
information to your engineer. It is important that a site/lot classification is
undertaken in accordance with Australian Standards AS 2870-2011 Residential
slabs and footings; AS 1726-1993 for Geotechnical Investigations. An Idealcorp
Site/Lot Classification consists of taking 2 bore logs where possible (this is
to profile the soil strata) and density tests to determine the soil
classification, along with a wind classification and a site classification.

What do we do on site? 

• Bore hole drilling identifies:
  • The subsurface soil strata (soil profiles)
  • Moist or hard soils
  • Determines the soil plasticity of clay (further laboratory testing maybe
    required to determine soil reactivity, included)
  • If fill is present on your site and the depth
  • If a water table is present
  • If there is rock or rock floating boulders on your site
• DCPs (Dynamic Cone Penetrometer) or PP readings – to
  determine soil density
• Fall of site – slope measured in degrees
• Wind classification – assists in designing roof structures
• Soil classification – Determines the soil type A, S, M, H1,
  H2, E. – reactivity of the soil
• Site classification – considers other aspects of your site,
  which may classify your site as a “P” (problem)

Why do I need a Site Classification (soil test)?

When a structural engineer is designing your home, the foundations are the most
important area of the engineering. Without appropriate foundations the house is
at risk of movement, cracking and potentially worse. Not all soil is the same.
Soil can be sandy, rocky or of a clay nature and many combinations of these
types. Soil variation can occur over extremely short distances. They all present
different challenges when a structural engineer is designing your foundations.
The soil may be prone to expansion and contraction, known as heave, common in
clay soils or it may be soft and collapsing creating stability issues. It may be
rocky which is great for stability but expensive if you are excavating a pool or
basement. A Site/Lot Classification provides the engineer with knowledge to
ensure they are designing the correct slab for the specific soil conditions of
your property. It supplies the engineer with a soil classification, this relates
to reactivity or heave in the soil, meaning how much can the soil expand and
contract when wet and dry. The report supplies a site classification which
relates to whether it is a P site, which alerts the engineer that there may be a
problem with water, trees, soft soils and other conditions that need to be taken
into account when designing the foundations.

Why buy from us?

We supply a large range of clients, from some of the largest project home
builders through to home owners building a granny flat or swimming pool. We make
it simple. Order online, you will be contacted to confirm our date on site, you
don’t need to be there when we come, we will be on site within the lead time
indicated when you place the order and your report will be completed and
returned via email. You now own this report and can provide it to any builder or
engineer of your choice to aid in the design of your project. Our report
includes things others charge extra for. We include shrink/swell (reactivity)
laboratory testing if required. We have the largest staff of employed
technicians in Sydney and surrounds, giving us control over our client service.
We are the only supplier who has an inhouse NATA accredited laboratory and we
have our own geotechnical engineer on staff. This allows us to provide a market
leading price, service and support to our customers as we do not subcontract the
work or testing to others.

What else do we do?

Acid Sulphate, soil infiltration, contamination, compaction, salinity and
durability tests are among some of the other services we provide. If these are
the tests you require please complete an enquiry form or call us to discuss.
