The water penetration test was conducted on an unfinished 100mm moladi wall which was exposed to an apparatus which replicates rainfall conditions equivalent to an annual rainfall of 1000mm per annum in conjunction with a wind speed of 30 metres per second. The rainfall conditions are based on that of the city of Cape Town, which has the most severe rainfall recordings in South Africa. The wall was exposed to the rainfall apparatus over a consecutive 24 hour period. It was concluded that moladi walls are certified as waterproof as it was able to remain impervious to exposure of the harsh rainfall conditions for the entire 24 hour period.
SOFT BODY IMPACT TEST
The soft body impact test was carried out on an unfinished 100mm moladi wall which was subjected to a collision from a 30kg sandbag at various velocities. The sandbag was attached to a pendulum-like apparatus and released from a swing height of 900mm to test the serviceability criteria of a moladi wall. Thereafter, the sandbag was released from a swing height of 1800mm above the point of impact in order to test the safety criteria of a moladi wall. After each collision the wall was thoroughly inspected to assess damage sustained by the moladi wall, such as collapse, cracking, superficial damage or depressions. It was recorded that no damage was sustained.
CHISEL IMPACT TEST
The chisel impact test was carried out on an unfinished 100mm moladiwall which was subjected to two consecutive strikes of a chisel at a very high velocity. The chisel was released from a height of 375mm above the unfinished floor level to test the strength and impact resistance of a moladi wall. A slight indentation of less than 3mm just above the chisels point of impact was recorded.
