Drop them side by side and break or cut them to fit around shapes as needed. No tape, staples or glue is required.
Our forms are designed to support grade slabs and beams from 5 inches to 6 feet thick as stated in specifications.
Our products are molded from 100% recycled waste paper. Reliable Void Forms lose strength when exposed to environmental moisture and also allow the soil to expand into the form without affecting the slab.
Reliable Void Forms are strong enough to support the placing and curing process in wet and rainy conditions.
