eVos-eTen slabs are Voided-PT slabs, based on two featured construction techniques Voided Slabs and Post-Tensioned Slabs. eVos is a superior bi-axial voided slab system, it creates voids within the concrete slabs in about 30-80% of the total slab area, replacing large quantities of concrete and dramatically reducing slabs self-weight. The compressive force applied to post tension strengthens the concrete to create thinner plates while providing enhanced crack resistance and greater deflection control. 

eVos with Post tension is developed to integrate the benefits of eVos and post-tensioning in one slab, hybrid slab. Hybrid slabs are longer, thinner, lighter and capable of spanning further than traditional reinforced concrete. eVos -Post tensioned (hybrid) slabs are sustainable alternative to traditional reinforced concrete. Reduced quantities of concrete and reinforcement together with use of 100% recycled eVos void formers help to lower CO2 emissions and reduce the carbon footprint of the building.
