Interlocking block making and building is a construction technique that utilizes interlocking blocks to create sturdy and efficient structures. This method involves the use of specialized machines to produce interlocking blocks made from a mixture of cement, sand, and water. These blocks are designed with grooves and ridges that fit together perfectly, ensuring a secure and stable construction. The interlocking blocks eliminate the need for mortar or cement joints, making the building process quick and cost-effective. This technique is widely used in the construction industry due to its versatility and durability. It allows for the creation of various types of structures such as houses, schools, and commercial buildings. Interlocking block making and building is an innovative and sustainable approach that promotes sustainable development and provides a solution for affordable housing.
