A grid-top floor tile for outdoor use includes a polymer tile having a grid-type top surface with multiple levels, such as a bi-level surface having an upper lattice and a lower lattice oriented generally transverse to the upper lattice. The multiple levels of the surface are preferably integrally formed with one another and provide drainage gaps therethrough. In a bi-level surface configuration, the lower lattice has a top surface below a top surface of the upper lattice, so as to draw residual moisture below the top surface of the upper lattice. The tile further includes a support structure, configured to support the tile on a support surface and provide drainage pathways beneath the top surface. The tile still further comprises various reinforcement members on each of the loop and pin connectors used to interlock the tiles when forming a flooring assembly.
