When selecting the fill it is important to follow the practical guidelines on what type of soil you can use. The ideal filling is clean granular soil such as crushed rock, gravel or sand. The practical guideline stats that filling must be granulate, it must contain no organic substances such as wood and it should not contain clay as it will shrink and expand. The ability of the fill to carry load without failing or settling will depend on how tightly the grains are packed together; in other words, on the density of the clay. Filing should always be applied…show more content…
We know out of experience that brick work can satisfy all this requirements. To prevent damp in walls an impervious sheet is laid over the full foundation wall width on the floor level, minimum of 150 mm above the natural ground level. A Polyethylene damp proof course of 0.375mm (SANS 952 type B, black) is laid on the foundation wall. Brickwork walls can be structural where they surround the building and carry the loads of the roof and floors or it can be non- structural where the wall only carries its own load. The superstructure wall starts on top of the foundation wall and ends just before the roof structure on ceiling level. In single story structures is there no deference in the required minimum compression strength of brickwork unit (7.0Mpa solid) or mortar (class2) for structural or non structural walls. In double story structures the compression strength of brickwork raise to 10.5 Mpa for hallow walls, meanwhile the mortar strength unchanged stay. The strength of structure brickwork depends…show more content…
• The mortar and the compression strength of all the brick unit. • The type of bonding in which the brick units are laid in. • Tightness, height and length of the wall. • If the structure brickwork in the wall is reinforced or not. Brick walls are build by laying bricks in a line that overlap. Bonding is the patron in which the bricks. There are deferent types of bonds: • Rowlock bond • Stretcher bond • Sailor bond • Soldier
