Precon Hollow Blocks

  • Density 1630 KG/M3

Percon by Nishu is made of Permeable or Porous or Pervious or No-fines concrete. It is a special type of concrete with a high porosity used for concrete flatwork applications that allows water to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.

Percon is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. It is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses. It is an important application for sustainable construction which protects water quality.
