Local
Economy component = 27%
Foundation in mud mortar of 450 x 450mm over 600 x 600 mm footing in class II bricks
DESIGN EXAMPLE : Foundation for a single 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) = 125 KN/sqm
 
W (weight of soil)    = 18 KN/sqm
 
Angle of repose of the soil = 30 = 125/18x0.111 = 0.77m.
 
Assuming bearing capacity of soil = 200 Km/sqm
 
Width required  = 125/200 = 0.625m
 
Thus provide a foundation width = 76cm and depth 77cm
 
Critical Factors
 
·      Quality of Soil
·      Width and Stepping of Foundation
·      Breaking of vertical joints
·      Protection from water
·      Availability and Cost of Bricks

 
Tools Used
 
·      Trowels
·      Plumb bob 
·      Thread
·      Pans
·      Shovel
·      Pick axes
·      Baskets
 
DO’S
 
DON’T’S
 
·         Soil should have medium Plasticity
·         Vertical Masonry joints should be properly broken
·        Masonry should be stepped after one day’s Construction
·      Excessively sandy and clayey soil should not be used for masonry mortar
·      Height of Masonry construction should not be more than 1m per day
·      Masonry should not be allowed to dry out quickly
