good foundation. Referring to Figure38, the dimensions 

 A and B should be all equal to the thickness of the outer 

 wall at the bottom with the limitation on dimensions 

 B as noted above. 



The floor of the tank may be made monolithic, in 

 which case it should be reinforced as shown in Figure 

 37 with " Steelcrete " mesh 3-13-075. The side walls 

 should be securely tied to the floor, as indicated in the 

 same figure, with 3-9-20, except that where the lower 

 layer of mesh on the side walls is of a lighter size, that 

 same size may be used for this purpose. 



The life and efficiency of a concrete tank depend 

 upon its impermeability or resistance to leakages. 

 Whether water-proofing compounds are used or not, no 

 detail is more important to observe than that all the 

 concrete should be poured in as nearly one operation as 

 possible. If it is not possible to do this in one operation, 

 the floor should be made in one and the outer shell in 

 another. This is of so great importance that the designer 

 should nothesitate to insist on day and night work to attain 

 this end. This brings us to the subject of waterproofing.
