What we do
Void Filling
NPPF’s Expanded Polystyrene (EPS) Geofoam offers a high-performance, lightweight, and reliable solution for filling voids in civil, construction, and infrastructure projects. Whether used under roads, bridges, airport runways, or buildings, NPPF Geofoam reduces structural loads, accelerates construction, and delivers long-term stability. Its excellent compressive strength and ultra-lightweight nature make it ideal for challenging soil conditions, areas requiring elevation adjustments, and spaces where traditional fill materials would be too heavy or impractical.
NPPF Geofoam meets or exceeds ASTM D6817 specifications and is available in densities from 12–50 kg/m³, offering high load-bearing capacity with minimal deformation. It is easy to handle, cut, and install—making it a cost-effective choice that reduces labor, time, and equipment needs.
Lightweight Fill
How can it help my business?
Used where traditional fill would overload underlying structures, such as podium slabs, podiums, rooftops, or over weak soils.
Advantages:
- Minimizes dead load and soil stress
- Easy and quick to install
- High compressive strength with low weight
- Long-term dimensional stability
- Non-toxic, chemically inert, and resistant to decay
Road Widening
How can it help my business?
EPS blocks prevent differential settlement and reduce subgrade stress in road widening projects.
Advantages:
- Lightweight with high compressive resistance
- Eliminates need for compaction or fill testing
- Fast and efficient road construction
- Minimizes impact on nearby roads and utilities
- Ensures long-term pavement stability
Bridge Abutment Backfill
How can it help my business?
NPPF Geofoam reduces lateral pressure and prevents settlement behind bridge abutments.
Advantages:
- Lightweight yet supports heavy structural loads
- Reduces differential movement at bridge approach
- Saves on reinforcement and reduces future maintenance
- Simplifies construction near sensitive zones
Retaining & Buried Wall Backfill
How can it help my business?
EPS geofoam is ideal behind retaining walls where weight and pressure need to be minimized.
Advantages:
- Up to 100 times lighter than traditional backfill
- Decreases pressure and soil movement
- Increases wall life and safety
- Quick to install and shape on site
- Ideal for segmental and curved retaining structures
Airport Runways & Taxiways
How can it help my business?
Used under runway shoulders and taxiways to prevent settlement and ensure smooth operations.
Advantages:
- Withstands repeated loading and thermal changes
- Efficient and non-biodegradable with long service life
- Reduces vibration and noise transmission
- Saves time during runway upgrades or expansions
- Replaces weak subsoils to improve overall stability
Rail Embankment Fill
How can it help my business?
EPS supports railway infrastructure by providing uniform, stable embankment fill.
Advantages:
- Reduces subgrade stress in poor soil areas
- No compaction needed, saving time
- Ensures consistent support for rail tracks
- Long-lasting and resistant to moisture and decay
Bridge Under Fill
How can it help my business?
Fills spaces beneath bridges while reducing the load and supporting structural transitions.
Advantages:
- Prevents settlement at bridge ends
- Easy to shape around complex forms
- Lightweight and durable under dynamic loads
- Reduces maintenance and repair cycles
Floor Raising
How can it help my business?
EPS is used for raising floors in commercial, industrial, or infrastructural spaces.
Advantages:
- Precise leveling with high strength-to-weight ratio
- Reduces concrete volume and slab thickness
- Compatible with ducts and service lines
- Fast installation with minimal disruption
- Long-term support under heavy foot or equipment loads
