Masonry sub-flooring

Abstract

A device for use in constructing a support surface for pavers and paving bricks comprising a planar tread surface; two elongated complementary mounting members being disposed at respectively opposite ends of the device and extending over substantially the entire width of the device, adapted to overlap and interlock. Thus when two devices are arranged end-to-end the complementary mounting members are fitted together and overlapping one another to define a mounting area. Each mounting member further includes a fastener receiving means, the fastener receiving means being located such that when a portion of the mounting member overlaps a corresponding portion of a complementary mounting member, the fastener receiving means of the portions are aligned to receive a single fastening element. The device further comprises two elongate engagement members disposed at opposite sides of the device and having shapes which are complementary to each other so that two devices can be arranged side-by-side with the complementary engagement members fitted together; and a grid-like area between said members including openings which pack, retain and support fine particulate matter, such as sand, marble dust, etc while simultaneously allowing water to drain through.

1 . A method or process for use in connection with covering an area with pavers and paving bricks comprising the steps of covering said whole areas with about 2 inches of gravel; packing the gravel over the area; laying a grid unit on top of the compacted gravel one grid unit at a time, by placing it end to end and side by side to other grid units already laid down, such that their sides interlock the grid units into place, and the entire area to be paved is covered with one continuous surface of grid units; compacting and locking the units into the gravel and into place; pouring and sweeping sand on and into the grid units covering the area; setting the paving bricks on top of the grid unit surface; and when all of the brick is set, sweeping sand into the brick.
