Benefits of Interlocking Blocks and Bricks

Although building techniques and materials have evolved over thousands of years, construction is still a long, complex, and expensive process. And it is, by and large, not environmentally friendly. The energy required for construction, the materials used and the pollution that is to be found in the construction area are among the many things that negatively impact the environment. Interlocking blocks may not solve all construction problems, but they do resolve many issues associated with traditional materials.

  1. Interlocking blocks may not solve all construction problems, but they do resolve many issues associated with traditional materials.

    1.What are Interlocking Blocks?

    Interlocking blocks are like 2 adjoining pieces of a jigsaw puzzle. Each block has a projection at one end and a depression at the other. The projection of one block fits in to the depression of the next so that they always align perfectly. The blocks have vertical holes in them which have a double purpose. Firstly, the holes reduce the amount of material required to make the block without compromising on it strength. Secondly, steel rods can be inserted or mortar poured into them to increase the building’s strength and stability. A paper presented at the 13th World Conference on Earthquake Engineering in Vancouver, Canada by Martin Wieland and R. Peter Brenner proved the structural benefit of this construction method.


    There are two main materials used in the manufacture of interlocking blocks. Soil cement blocks are made using a soil to cement ratio of between 1:6 to 1:10. Concrete blocks are made using cement to sand to gravel ratio of 1:5:3. To find the manufacturers and suppliers of different kinds of interlocking blocks in your area, you can check online to narrow down your search list.

  2. 2.The Advantages of Interlocking Blocks

    Interlocking blocks offer numerous advantages to other building materials. The materials required for production are widely available so they do not have to be shipped in from long distances. Since the manufacturing process is a simple one, production facilities can be easily set up at convenient geographical locations, once again reducing the cost of transporting them to the construction site. In the case of very large construction projects, an interlocking block production facility can be set up at the construction site to provide the most cost effective supply solution.


    Another cost saving is achieved because the simplicity with which the blocks can be laid and aligned reduces the number of high wage skilled masons required on a construction project. When compared to convention masonry block construction, interlocking blocks, which are dry assembled, save a great deal of mortar which is normally used for vertical and horizontal joints, which again produces savings in terms of both cost and time.


    Any time you can save time is critically important. This means you can start building later on in the summer knowing you can have it completed before the rain and snow begin to arrive in sleets which can severely hamper the progress on any work site. This enables an owner or a business to be able to begin selling goods and/or services throughout the winter and sooner than if a building could not be started at all until the spring.


    The structural stability and durability of interlocking blocks is much greater than that which is offered by timber construction. Another benefit is that, unlike timber, interlocking blocks are immune to termite and other insect damage. Vulnerable and high stress parts of a building can be reinforced by running steel bars through the aligned holes of the blocks. Because of the ease and economy with which interlocking block walls can be built, load bearing walls can be used where infill walls would normally be placed, thereby providing both additional strength and load bearing ability to accept future additions to the building. Interlocking block construction techniques can be used for everything from single to multi-story construction.

  4. 3.Interlocking Blocks are Used Everywhere

    Initially popular in East Asia as an alternative of fast depleting timber resources, interlocking blocks have gained international acceptance for the many benefits they offer and are now used all over the world for all sorts of construction and structure building.
