  Brick Foundation in Cement Mortar 1:8
System Components
Initial Cost Structure
DESIGN EXAMPLE : Foundation for a TWO storey Building
Maximum width required = 2 x width of the wall +0. 3m
(Assuming 23cm thick brick wall) = 2 x 0.23 + 0.3 m.
                                                = 0.76m.
Minimum Depth Required = 
Assuming P
Safe permissible pressure on base) = 175 KN/sqm
W (weight of soil)                           = 18 KN/sqm
Angle of repose of the soil = 30 = 175/18x0.111 = 1 m.
Assuming bearing capacity of soil  = 200 Km/sqm
Width required                             = 175/200 = 0.85m
Thus provide a foundation width  = 85cm and depth 100 cm
