TephraLite

Lightweight Aggregate for Concrete Applications

TephraLite lightweight aggregates are suitable for virtually all structural lightweight concrete applications that require a high-quality material with proven and reliable characteristics. The sustainable aggregates quarried and produced near Quesnel, British Columbia, Canada, consist of red vesicular basalt and black scoria. The benefits of TephraLite lightweight aggregates for structural lightweight concrete are well established. Its low water absorption and high durability compared to common lightweight aggregates combined with its superior performance and ease of use make TephraLite your best choice for structural lightweight concrete applications.
