The problem
When constructing buildings in swellable clay soil, one of the challenges is the lifting of the soil due to moisture fluctuations, particularly during extended dry periods. To address this issue, a common practice involves placing expandable polystyrene (EPS) blocks in the foundation before pouring the concrete floor. These EPS blocks act as an insulating layer, allowing the soil to move and breathe without compromising the integrity of the structure.
EPS is recognized as a contaminated material, both in its production phase and when used in construction. Additionally, a significant issue arises when the EPS block fails to break or exert pressure when the soil undergoes dewatering.
The Bioplasmar solution
Bioplasmar’s innovative solution, Bio-Build, was specifically developed to provide stability to building floors constructed in swelling soils. This surfacing material is created using Bioplasmar’s organic waste materials, making it an environmentally friendly choice. Unlike traditional materials like EPS, Bio-Build naturally degrades under the concrete after serving its purpose during construction.
One key advantage of Bioplasmar’s approach is its utilization of green and renewable waste materials, in contrast to the non-renewable energy sources used in conventional methods. Additionally, Bio-Build offers the unique benefit of allowing direct application of the bitumen layer, which is not possible with EPS. This not only saves the need for an additional concrete layer but also makes the overall process more cost-effective.
Another significant advantage of Bio-Build is its biodegradability. This ensures that the material does not persist in the environment unnecessarily and aligns with sustainable practices. Furthermore, Bio-Build provides sufficient space for soil swelling, mitigating potential issues associated with the expansion of swelling soils.
