Interlocking tiles as a good solution to external floor coverings has been one of the choicest in all cities of Nigeria. This research was aimed at examining the effect of various production methods used among artisans within Ilorin metropolis on the physical and mechanical properties of commercially produced interlocking tiles. Also, the laboratory production of the interlocking tiles adopting the commercially used methods was carried out. Results of the physical and mechanical properties of interlocking tiles produced showed bulk density of tiles ranging from 2.04 to 2.26 g/cm3, water absorption capacity ranging from 4.87 to 7.81%. Maximum compressive strength was also observed in interlocking tiles produced using vibration compaction method and an average compressive strength of 20.51 MPa was obtained compared to mortar method with average compressive strength of 13 MPa. Flexural strength for vibration compaction method was peak at 1.25 MPa for 8 mm particle size interlocking tiles and minimum at 0.89 MPa for 4 mm particle size interlocking tiles. Interlocking tiles with 4 mm grain size had the maximum mechanical strength. An efficient and sustainable method of production of interlocking tiles can be adopted and replicated by all commercial tiles
