Stabilizing construction in swelling soil
Floor lifting due to changes in humidity levels, especially during long periods of dry weather, is a problem of current construction in swelling clay soil.
The current method used to prevent this phenomenon is laying EPS (expandable polystyrene) blocks in the construction’s foundation, when pouring the concrete floor. This provides insulation by creating an extra layer that enables soil movement and breathing, without damaging the construction.
However, after the drainage, the EPS is no longer needed, but it cannot be removed. This is problematic since at times it causes serious damage in the form of floor floating.
To ensure a stable construction floor in swelling soil, Bio&Build was created, a surface made out of Bioplasmar's appropriate organic waste materials. This surface serves as long as needed for the implementation, and then biodegrades naturally underneath the concrete.
Bioplasmar’s main advantege is the use of green, renewable waste, instead of fossil nonrenewable energy.
Further, one can directly implement the bitumen layer on the Bio&Build, which cannot be done with the EPS, which is sensitive to heat.
Bio&Build is much more cost effective as it saves an additional layer of concrete, biodegrades within weeks, and allows additional space for swelling.
