1. Lightweight concretes and screeds

Exfoliated vermiculite can be used as a replacement for dense aggregates to produce a lightweight insulating concrete. This finds use as in-situ roof and floor screeds and in the fabrication of precast products. It is also used as a back fill where improved insulation is required.

Lightweight roof screeds, as a slope to drain, not only shed water but can reduce the steel structure design while providing a smooth insulating roof substrate for the roof membrane.
