Rapidfill Technical Information

Trench Breaking

Trench breaking involves placing a barrier—typically made of lightweight, durable material—within a trench to control water flow, prevent erosion, and protect infrastructure. NZ Foam’s Rapidfill is ideal for this, forming a strong, impermeable seal that installs quickly and adapts to any terrain.

Light Weight Fill

Lightweight fill is used to reduce ground load in areas with poor soil conditions or weight-sensitive structures. NZ Foam’s Rapidfill provides a high-strength, low-density solution that installs quickly, bonds to the substrate, and delivers long-term stability without adding unnecessary weight.

In Ground Pools

In-ground pools often require void filling or backfilling to stabilise the surrounding ground and prevent movement over time. NZ Foam’s Rapidfill is ideal for this, offering a lightweight, water-resistant solution that conforms to complex shapes, provides excellent support, and ensures long-term ground stability.
