Our Terefil® technology provides an advanced lightweight cellular concrete for soil replacement, large void filling, and pipe abandonment.
Advantages of Cellular Concrete: Beyond Traditional Mixes
Cellular concrete stands out for its unique properties, catering to a wide spectrum of applications.
It boasts a lower density, ranging from 500 to 1500 kg/m3, which is a stark contrast to the 2,400 kg/m3 found in traditional concrete.
Though its compressive strength, which spans from 0.5 to 5 MPa, might seem low compared to standard concrete, it perfectly meets the needs of scenarios prioritizing a lightweight, free-flowing material.
The Fluidity Factor: Cellular Concrete in Action
One of the standout attributes of cellular concrete is its high fluidity. This material can be pumped over long distances, filling gaps, trenches, or voids.
There is typically no need for levelling or compaction. This fluid nature proves invaluable when filling trenches, decommissioned pipelines, or spaces behind retaining walls, as it seamlessly flows around obstructions, ensuring a consistent fill.
Soil Replacement with Terefil®
In a ground improvement application, Terefil® is used to create a lightweight raft prior to building construction.
Weak, compressible or liquefiable soils are excavated to a designed depth and replaced with cellular concrete. This reduces the weight on the underlying soils and provides an engineered fill material with consistent strength and stiffness properties.
Unique Features of Terefil®
Adjustable Density
Terefil® can be tailored to a density range between 500 – 1,500 kg/m3, fitting diverse project needs.
Reliable Compressive Strength
Starting at 0.5 MPa, its compressive strength can be modified based on the desired density.
Rapid Installation
With a rate of up to 40 m3 per hour, Terefil® ensures a time-efficient installation process.
Quick and Consistent
Terefil® sets in just hours and offers a self-levelling, highly flowable application.
