Industrial (Packaging, Absorbent):
- Vermiculite is used as a lightweight filler, liquid absorbent for dangerous goods and lab packing and as a liquid waste solidification agent.
Construction (Insulation, Concrete Aggregate):
- Vermiculite is ideal as a pool base under vinyl lined pools, chimney insulation mix, light weight aggregate in plaster and concrete, attic insulation, aggregate in spray-on fireproofing and as a masonry fill insulation.
Horticultural (Lt. Wt. Soil Amendment, Seed Topping):
- Light weight Vermiculite provides aeration and moisture retention.
- It also possesses cation exchange properties, thus it can hold available to the growing plant ammonium, potassium, calcium and magnesium.
