The foundation is completed when the slab floor joists meet with the slab slab. Another important thing to know is that an underneathlayment cannot be used for any type flooring. The foundation and underpinning must be made of rubber, foam, or rigid plastic. Your underlay should absorb moisture from the soil around the foundation. This will not only keep your foundation dry but will also ensure that the slab floor will be strong and durable.
