About the Concrete Block Company

We are the only company in Costa Rica to offer well engineered, concrete solutions, utilizing Lock-Block technology. Created in 1984,  Lock-Block Ltd's products feature their signature proprietary interlocking key design, establishing them as a leader in pre-cast concrete block retaining wall systems. The production process has been proven in independent engineering studies to offer greater tolerances and strength than all other comparable systems with straighter joint lines and less potential for movement of units under high-stress conditions.


The Concrete Block Company can offer concrete units ideal for a range of commercial and residential projects. They are safe, simple, and quick to assemble, making them more efficient than traditional construction methods. What usually takes more than a month with cast-in-place concrete, can be built in days using our concrete blocks.
