Bolt-A-Blok is a revolutionary, unitized post-tensioned, mechanically fastened block system.    Quality concrete blocks are connected mechanically by anti-corrosive steel fasteners and bars.  The fasteners and bars provide post tensioning which increases the overall capacity and acts as steel reinforcement to the wall.

Bolt-A-Blok system is significantly faster to assemble, stronger, safer, more economical, and environmentally friendly.  Bolt-A-Blok provides a superior alternative to current construction methods.  The overall cost is typically much less than masonry and poured or precast concrete. 

Bolt-A-Blok has limitless applications as compared to typical mortar-block, reinforced concrete, pre-cast concrete, and stick-built (wood) structures.   The system has immediate strength and requires no cure time or use of water.  Therefore, the building season is not restricted by temperature and inclement weather.  Bolt-A-Blok is a sustainable design.
