Also being made on the same machine as the Solid Blocks are also dense and with least drying shrinkage, water absorption and moisture movement.
Moreover they are even more water tight than the Solid Blocks as they are made from richer Concrete Mix.
PraYoSa's Hollow Blocks have well designed Grip Handles. This grip handles makes handling these blocks easier and also ensures that the mason always puts the Flared side of the Face and Web shells on the top to ensure wider surfaces or the mortar. This is a feature mentioned in IS 2180(part I) which is hardly taken care by any block manufacturers.
We request you to call the PraYoSa representative to explain you about such special features of PraYoSa Hollow Blocks.
