Geofoam

Insutech Geofoam blocks outperform soil or sand backfilling through several key technical advantages:

1. Exceptional Weight Reduction: Its density is up to 98% lower than traditional soil, radically decreasing dead loads on weak or unstable subgrades.

2. Compressive Strength: Engineered in various density grades to support high traffic and structural loads without significant deformation.

3. Rapid Execution: Large-scale blocks are easily handled manually or with light machinery, shortening project timelines by up to 50%.

4. Dimensional Stability & Durability: A chemically inert material that does not decay, is resistant to bacteria, and provides long-term structural stability.

5. 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:

1. Subgrade Leveling: The base soil must be perfectly level and free from sharp debris to prevent puncturing the blocks.

2. Block Placement: Blocks should be laid in a "running bond" pattern (like bricks) to ensure load distribution, using "mechanical connectors" if specified.

3. Protective Layering: Covering the Geofoam with a geotextile or geomembrane to protect it from petroleum spills or solvents.

4. Final Capping: Pouring a reinforced concrete slab or a paved base layer over the Geofoam to begin distributing traffic loads.
