Filler Slab construction is an innovative, sustainable, and economical building technique that is emerging in today’s construction world. This substitute material replaces the bottom parts of a concrete slab while not compromising on structural strength and durability. If you are into sustainable building methods, this technique finds its use in any scale and type of building. In this blog, we’ll explore the filler slab building approach by delving into its applications, benefits, drawbacks, and more.
As we know, a slab is a flat and horizontal structural element made of reinforced concrete that forms floors, roofs, and ceilings of a structure. But, what is a filler slab? A filler slab is also a reinforced concrete slab in which, an alternative material replaces the bottom of the slab. These alternative materials include cost-effective and eco-friendly materials like Mangalore tiles, clay pots, bricks, coconut shells, etc.,
The idea behind introducing a filler slab is that the lower half of the concrete in the RCC slab is in tension and doesn’t bear significant weight load. Furthermore, these substitute materials minimize the amount of concrete.
Laurie Baker, renowned for his focus on affordable construction methods, popularized the filler slab technique in the late 1900s. Based in Kerala, Baker drew inspiration from Mangalore tiles, leveraging their efficiency in design. Throughout his career, he promoted the use of locally available materials and energy-efficient building practices. His approach not only was cost-effective but also significantly reduced environmental impact by lowering the consumption of concrete and steel. Laurie Baker aligned the filler slab technique with his broader vision of promoting sustainable and eco-friendly architecture.
For different types of projects, various materials are selected as fillers based on design concepts, styles, availability, cost, aesthetics, and client requirements.
