51. SABS Test
Waterproof
• Test method is for the worst case
scenario i.e. Cape Town 1,000-mm
rainfall per annum with a wind speed of
30 metre/second conducted over a 24-
hour period.

52. SABS Test
Soft Body Impact
• A 30 kg bag swings to impact the wall 900 mm
above the floor height to access the
serviceability criteria
• 1800 mm above the floor height to access the
safety criteria.
• Two impacts of the bag where executed on the
exterior wall surface for each of the above
criteria and the wall was inspected after each
impact for any sign of cracks, damage or
collapse – none.

53. SABS Test
Chisel Impact
• After two impact of the chisel from a
height of 375 mm above the floor
height a slight indentation was visible.
The depth of the indentation was less
than 3 mm.

54. SABS Test
• All test conducted by the South African Bureau of
Standards, have been executed on a 100 mm (4
inch) wall as this is an acceptable norm for in situ
walls and is also the standard applied to low cost
housing units.
• Thermal conductivity of 100 mm moladi wall =
0,54 W/m.K
