TephraLite – Geotechnical by CanLava

“The Natural Lightweight Solution to Your Construction Challenges”

CanLava’s Tephralite is a high-quality lightweight red vesicular basalt, that is a cost-effective solution to many engineering challenges. TephraLite has a wide variety of uses and applications. We understand that one of the many problems faced by geotechnical engineers when developing designs for specific types of projects is the weight of natural fill used in construction. Our TephraLite delivers on all the required engineering characteristics needed to overcome the challenge of weight. TephraLite ensures great project outcomes over the long-term. This natural volcanic lightweight aggregate is a high performing material, test results prove it.
