PRACTICAL SILO CONSTRUCTION 



also keep out the surface water as well as retain 

 the moisture in the silage, 



FOUNDATIONS FOR THE SILO 



These must be given careful attention, as the life 

 of the structure depends upon same. The practise 

 of constructing the foundation in a haphazard man- 

 ner is to be regretted; for, when we consider the 

 weight of the concrete structure, as well as the weight 

 of the column of silage it contains, the vast impor- 

 tance of amply protecting this in constructing an 

 adequate foundation is easily to be seen. 



At Fig. 1 is shown the usual type of foundation 

 for a concrete silo, where the floor of same is at 

 ground-level, as indicated at a. The dotted lines 

 at 6 show the form of constructing footings, which 

 are determined by the size of silo. 



The following table will aid in determining the 

 diameter and size of the footing courses for the 

 different sizes of silos usually constructed.
