A sieve screen module comprising:
- (i) a plurality of interlocked sieve elements, each sieve element having a rectangular parallelpiped body formed with through apertures to provide a mesh, opposed edges of said body having castellated formations arranged and dimensioned so as to be interdigitated with the complementary formations of the juxtaposed elements to provide a smooth joint, the underside of said formations being grooved to form together a continuous channel,
- (ii) an elongate member extending along within said channel and a settable material contained in said channel which adheres to the elongate member and channel walls for locking said sieve elements together.
