ABSTRACT:
A bed-depth gauge consists of a guide member, a screed member, and means for assembling them for relative movement, for effective depth adjustment, in a vertical direction that is generally perpendicular to a bottom edge of the screed member. The guide member has a pair of arms that extend laterally, at different heights, which are used to engage and follow a fixed reference surface to thereby enable the bottom edge of the screed member to level and control the depth of both a base layer and also an overlying upper layer, comprising a bed prepared for installation of paving blocks and the like.
