SHORT DESCRIPTION:

• The LOK BILD System was developed by Dr. A. Bruce Etherington of AIT Bangkok and University of Hawaii, and has been tested in Malaysia, Thailand and the Philippines using cement concrete, and in the United Arab Emirates using sulphur concrete.

• The hollow blocks are designed to be assembled without mortar, producing perfectly aligned walls without special masonry skills. The system also includes precast concrete joists, which interlock with the concrete block walls to support in situ floors and roofs, and channel blocks, which are placed on top of the walls to make reinforced concrete ring beams.

• The interlocking blocks have narrow vertical recesses and a central cavity, which when assembled form continuous, vertically aligned holes over the full height of the wall. When cement grout is poured into them, the blocks become permanently locked together. Wherever necessary, eg at corners, cross-walls, or around openings, the large hollow cores can be filled with reinforcement and concrete, providing earthquake resistance.
