Project Overview

Expanded Polystyrene (EPS) Geofoam is an innovative and reliable material for use in foundation construction, providing a lightweight, stable, and thermally efficient solution for a wide range of building and civil engineering projects. Molygran’s Geofoam EPS blocks are engineered to deliver exceptional compressive strength and dimensional stability, making them ideal for use beneath slabs, raft foundations, and other load-bearing structures.

Benefits

  • Lightweight and Strong: Up to 100 times lighter than traditional fill materials while maintaining high compressive strength.
  • Improved Stability: Reduces load on weak subsoils, minimising settlement and structural movement.
  • Thermal Efficiency: Excellent insulation properties help reduce heat loss through the foundation.
  • Fast Installation: Easy to handle, cut, and install on-site, speeding up construction.
  • Durable and Sustainable: Resistant to moisture, rot, and chemicals, and fully recyclable.

The brief The brief

Traditional foundation systems often face challenges when built on weak or variable ground conditions. Heavy fill materials can increase settlement risks, while poor thermal insulation can lead to heat loss and reduced energy efficiency. The challenge was to find a lightweight, durable, and thermally efficient material that could reduce ground pressure, improve stability, and enhance the overall performance of the foundation system.

The solution The solution

Molygran supplied precision-cut EPS Geofoam blocks to serve as a lightweight foundation fill and insulation layer beneath structural slabs. The EPS blocks were designed to meet specific load-bearing and thermal performance requirements, ensuring both structural integrity and energy efficiency. Their lightweight nature simplified handling and installation, reducing construction time and costs.

The use of Molygran’s EPS Geofoam in foundation construction provided a stable, energy-efficient, and cost-effective solution. The lightweight fill reduced ground pressure and settlement, while the thermal insulation properties improved building performance. Installation was completed quickly and efficiently, with minimal environmental impact and long-term durability assured.
