Abstract
The invention provides a wall structure of precast concrete sections (2) having face surfaces (10) which resemble natural ledgestone, ashlar, rock face, or other stone textures surfaces and shapes. The sections are provided with grooves (14) at the upper (4) and lower (8) surfaces. The grooves accept overflow of mortar or adhesive which coats the surface to which the sections are to be bonded. Thus, the excess mortar is substantially hidden within the grooves where it acts as additional bonding between the layers of sections. At their lateral surfaces (6), the sections are angled to further resemble the appearance of natural stone upon installation. Methods of installation are also provided.
