Jumbo water repellent Gypsum Block is a lightweight wall building material composed of gypsum as the main material. It known as calcium Sulphate Dihydrate (CaSO4·2H2O). It contains auxiliary materials and additives and is made from calcination, stirring, forming and drying.

Every block is moulded with tongue and groove at all sides to enable fast and easy assembly. Due to no conventional cement-sand mortar or plaster being used, the walls are erected almost without water like drywalls.

It is used for building non-load bearing interior partition walls, and exterior walls. Walls built with Jumbo Gypsum Blocks are massive, crack-free and of high stability.
