A modular surface having an important use as a sports deck, and particularly for ball sports like tennis. The surface is built up of a number of generally square tiles in which the play surface is supported by a large number of support pegs intended to rest on an undersurface. The tiles are flexible so that the support pegs can remain in contact with the undersurface even if it is not perfectly plane, assuring consistent ball bounce. A special arrangement of expansion joints gears the ability of the tile to absorb expansion and contraction resulting from temperature changes to the geometry of the tile to: (a) keep the pegs on the ground even in the presence of temperature changes to assure consistent ball bounce, and (b) keep the play field itself from expanding or contracting without the need for anchoring it to the undersurface.

A module for a modular surface comprising a tile having an upper surface and a plurality of support means underlying the surface for engaging an undersurface, the tile being flexible to accommodate imperfections in the undersurface while keeping the support means in contact therewith, continuous floating expansion joints dividing the surface into square pads supported by said support means and oriented with diagonals generally parallel to the tile edges whereby the number and effectiveness of the expansion joints is greatest along the tile diagonal to maintain said support means in contact with the undersurface under conditions of changing temperature.
