Our Terefil® technology provides an advanced lightweight foamed concrete for soil replacement, large void filling, and pipe abandonment.
Advantages of Foamed 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: Foamed 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.
Specialised Plant & Equipment
The Terefil® LCC is produced by mixing the base grout and foam inline or mechanically to form the specified design mix.
The Terefil® LCC is produced by mixing the base grout and foam inline or mechanically to form the specified design mix and design density product. Mainmark produces LCC using a self-contained Terefil® mixing and pumping rig.
In remote or difficult access conditions, the equipment may be segmented to allow flexibility of access and ease of transport.
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.
