Concrete slab foundation path / lane are used when a wide cross section to use a local foundation slab is too large. Sectional area divided in a way so as not to lengthen the lane is too wide. This foundation is stronger than the other two types of shallow foundation.

This is due entirely composed of reinforced concrete, although the reinforced concrete, making the price of this foundation is cheaper than a foundation stone for the building terraced houses. Size –  equal footing plate width lane down the foundation stone, which is between 70-120 cm. Use of these widths due to the function of this lane slab foundation is cut stone to replace the foundation, especially if the cut stone is very difficult to obtain, or indeed there are plans to build houses up or level.

a. How to calculate the volume of concrete
How to calculate the volume beron for the foundation of this type are as follows.
Volume foundation = (Volume I Volume II) x length of foundation slab.

Volume I = cross-sectional area x height foundation

Volume II = ((a + b) / 2)*b

Description: a. = Width of the top of the foundation
b. = Height of foundation
c. = Width of the foundation brought

b. Calculate the material needs
Supplies materials for volume 1 m3 of concrete slab foundation with cement mortar 1: 2 sand: 3 split is

1. Stone broken / split 2 / 3 as many as 83 m3 (0.83 m3 x 100)t
2. Concrete sand as much as 54 m3 (0.54 m3 x 100)t
3. PC as much as 850 bags of cement (8.5 bags x 100)t
