It is used as a lightweight filling material in reinforced concrete hollow block slabs. Pocketed Lightweight Hollow Block, like other LENTOSAN products, enables the construction of lightweight, earthquake-resistant, and economical buildings.

Hollow block increases building comfort by providing sound and heat insulation in slabs. Due to its easily cut structure, it does not generate waste during application. Pocketed Hollow Block, which does not fill with concrete due to its void-free structure, provides concrete savings of up to 15% in slabs. Thanks to the smooth surface formed on the slab, plaster savings of 30-40% can also be achieved.
