Height limits can approach 36 feet for three-storied load bearing walls.Ĭonsideration For Dry-Packed Interlocking Masonry Construction a) Cornersĭry-packed interlocking masonry construction should be started at the corners. Reinforced grouted walls provide masonry assemblies with properties and load capacities similar to conventional reinforced masonry systems. In grouted construction, dry-stacked units have their cores partially or fully filled with grout, including horizontal and vertical reinforcement.Height limits can be as high as 21 feet 8 inches for two-story load bearing walls. For surface-bonded walls, dry stacked units can be finished on both sides with a cementitious or acrylic bonding matrix reinforced with fiberglass mesh or plastic fibers as rain and air barrier, as well as providing the final surface finish and color.Plain dry-stacked units can be used for retaining walls, foundation walls, partitions, and load-bearing walls up to about 9 feet tall in structures not intended for human occupancy.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.

Interlocking concrete blocks code#

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.
