blocks have tongue and groove profile to form interlocking masonryInterlocking Shear key makes masonry Earthquake resistentBlocks have exposed brick finish requiring optional plasterBeveled edge blocks ease handling and smooth flow of rain water on wall faceCompatible for both Load bearing and for In fill applications Unskilled / semiskilled workers can also make blocks and masonryHydraform blocks and masonry are compatible for Green Building Interlocking blocks facilitate speedier, cost effective and greener construction requiring no post construction work No investment required in pallets for stacking blocks during curingMasons find Hydraform interlocking masonry simpler and faster and give better productivity Hydraform block machines can be set on construction site itself, avoiding multiple handling and transportation Flexibility to alter density & compressive strength to suit project requirement Option to use waste materials for making block
