Structural Engineers, “Design Methodology-The Haener Interlocking Mortarless Block System” August 1989) This type of masonry system relies on self-weight to resist external forces through interlocking mechanisms of shear keys.ĭry-Packed Interlocking Masonry Construction Types of Dry-Packed Interlocking Masonry Constructionĭepending on the type of occupancy of the building, the assembly of dry-packed masonry can be completed in one of the three ways: plain, surface bonded, and grouted (Ref. In this method of masonry construction, blocks are not laid on mortar except in the first two block layers above DPC and top two courses leading to roof band.Īs per the requirement of IS 4326:1993 (Indian Standard for Earthquake Resistant Design and Construction of Building – Code of Practice), a thin mortar of the specified type can be used even in these Interlocking types of the blocks. Though still uncommon, these systems could be used to construct strong, durable, and cost-effective buildings. It is a mortarless masonry system using blocks that interlock to provide leveling and alignment. The walls constructed using this system may be left exposed, plastered or finished with cement paint. The system of dry-stacked interlocked masonry enables affordable building construction, speedier construction of high quality in stretcher bond as well as enhanced aesthetic properties. A mortarless dry-stacked interlocking masonry system consists of Interlocking compressed earth blocks(ICEB) or concrete interlocking blocks or fly-ash interlocking blocks that are laid dry-stacked or with minimum mortar slurry in a stretcher bond in a wall.
