  5. 5. Slab on Ground Constructions The Australian Standard AS 3660.1-2000 Termite management Part 1: New building work specifies that a slab on ground should be designed and constructed either in accordance with AS 2870 or AS 3660. Section 2: Performance Criteria 2.3.1 Concrete slabs as termite barriers • A concrete slab or footing used as a termite barrier shall (a) be designed and constructed so that any cracks passing through the slab or footing do not exceed 1 mm in width through the depth of the slab; (b) have all interfaces between the penetrations and slab or footing provided with a termite barrier system integrated with the slab; and (c) have all joints, except for tied footing slab construction joints, provided with a termite barrier system integrated with the slab.
  6. 6. Legislation • Queensland amendment to the BCA. • BCA amendments only apply to building classes 1 & 10 • AS2870 -2011 Residential Slabs and Footings • Soil Classification – A, S, M, H, E, P − Slightly reactive to Extremely reactive. 6

  36. 36. Ventilation Sub-floor ventilation is often a forgotten part of termite management. The BCA (Vol. 2) requires the sub-floor between a suspended floor and the ground to be ventilated. AS3600 specifies ventilation to be minimum of 8,400 mm squared nett ventilation/Lm This minimises sub-floor moisture which helps to prevent timber decay, and creates an environment that discourages termite attack. To be effective, acceptable sub-floor construction must: •Be free of building debris and vegetation •Provide cross ventilation, •Contain no dead air spaces •Be graded to prevent ponding and be above the external ground level •Have evenly spaced openings 36
