Abstract
A floor or wall covering has blocks with mating strips having multiple ridges and multiple grooves in both mating members. Ridges and grooves can have different sizes and cross-sectional shapes from one another, and can mate in a manner that provides expansion gaps. Male/female positioning pairs can advantageously be included to facilitate alignment of the blocks during installation and use. Preferred floor blocks comprise a ribbed support portion that supports a working surface, and the ribbed support portion defines a plurality of cells that collectively reduce the weight of the block by a factor of at least 20% relative to corresponding block without such cells.
