They are designed and tested to withstand & proof load of 112.5KN and ultimate load of 140KN. The applied area is 320mm x 320mm at any position of lid-slab.
Southern Concrete Box Culverts are suitable for use in construction of:-
a) Open Drain
c) Tunnel, Sumps etc
Compare to cast in-situ structures they have many advantages such as:
a) Consistency and reliable cast concrete products
b) Shorter construction time
c) Easier field supervision
