Abstract
An intermeshable construction unit for constructing structures, such as walls, paving, screens, embankments and the like without mortar is disclosed. The intermeshable construction unit has a body portion which is block-like in shape. The body portion has a top, a bottom, a front end, a back end, and two opposed sides. A central spine having two sides runs along the central axis of the body portion between the front end and the back end. A plurality of teeth protrude from both sides of the central spine to form a web with each of the teeth terminating along the opposed sides. The teeth are separated by notches which have a width greater than the width of each of the teeth so that the units may be aligned, whereby one intermeshable construction unit may be meshed with another intermeshable construction unit to interlock the units. The intermediate construction units may be adapted within three planes during construction, namely the vertical, horizontal and diagonal planes. Thus, by staggering or off-setting the teeth from notch-to-notch, several patterns for structures can be designed for easy construction on sight by general labor. To increase the load bearing capacity of the intermeshable construction units, the units may be laid on a designed aggregate base in combination with geotextile fabrics.
