This certificate relates to the Megacom Building System for the erection of single story attached and detached houses.

The Megacom building system comprises hollow interlocking concrete blocks that are dry-stacked (no mortar between horizontal and vertical joints) to form the walls of dwellings. The first levelling course is, however, bedded in mortar on the surface bed or strip footing. Core columns (cavities in the blocks filled with concrete and a continuous vertical reinforcing bar) stabilise external and internal walls and are required at specified positions. A continous ring beam is formed above window and door height by placing reinforcement in a minimum of two horizontal rows of blocks and filling all cavities with concrete. Internal walls are bonded to external walls with hoop-iron clips and reinforcing bars. Internal and external gable walls are reinforced and the cavities above ring beam height are filled with concrete.

Double pitched roof construction comprises timber purlins or mild steel lipped-channel purlins (wire tied to the ring beam) and profiled steel sheet roof cladding.

Window and door frames are of the Clisco type, manufactured from pressed mild steel.
Walls are finished externally with a skim-coat or conventional plaster and acrylic paint. Internally walls are skim-coat plastered, or plastered both sides where required.

Foundations can be either thickened edge beams and thickened surface bed under internal walls, or conventional strip footings with concrete block foundation walls filled with concrete.

The certificate covers the use of the building system in all areas of South Africa excluding the SCCP area for the erection of single storey buildings of the following occupancy classifications as defined in Table 1 of Regulation A(20)1 of SABS 0400 of 1990: H3 & H4: attached and detached houses and their related outbuildings.
