Geofoam
Geofoam
Geofoam It is used to drastically reduce vertical and lateral loads on soil and retaining structures, preventing settlement issues in roads, embankments, and bridges.
Insutech Geofoam blocks outperform soil or sand backfilling through several key technical advantages:
Exceptional Weight Reduction: Its density is up to 98% lower than traditional soil, radically decreasing dead loads on weak or unstable subgrades.
Compressive Strength: Engineered in various density grades to support high traffic and structural loads without significant deformation.
Rapid Execution: Large-scale blocks are easily handled manually or with light machinery, shortening project timelines by up to 50%.
Dimensional Stability & Durability: A chemically inert material that does not decay, is resistant to bacteria, and provides long-term structural stability.
Lateral Pressure Reduction: When used behind retaining walls, it significantly reduces lateral earth pressure, allowing for thinner wall designs and lower reinforcement costs.
Insutech Geofoam is the ideal solution for complex geotechnical applications:
Bridge Abutments & Embankments: Building roads over soft or clayey soils without the risk of sudden settlement.
Retaining Wall Backfill: Reducing lateral forces to save on concrete and steel costs in wall construction.
Rooftop Landscaping: Creating slopes, mounds, and aesthetic levels on building roofs without exceeding structural load limits.
Pipeline Protection & Insulation: Providing a protective layer and mechanical insulation for large underground utility lines.
Stadium Seating & Auditoriums: Constructing tiered seating platforms rapidly and with minimal added weight.
To ensure stable engineering performance of Geofoam, the following protocol is recommended:
Subgrade Leveling: The base soil must be perfectly level and free from sharp debris to prevent puncturing the blocks.
Block Placement: Blocks should be laid in a "running bond" pattern (like bricks) to ensure load distribution, using "mechanical connectors" if specified.
Protective Layering: Covering the Geofoam with a geotextile or geomembrane to protect it from petroleum spills or solvents.
Final Capping: Pouring a reinforced concrete slab or a paved base layer over the Geofoam to begin distributing traffic loads.
