Customer Questions & Answers

We are putting this down. Do you use duck tape to hold in place or some other way to keep it from shifting 

Asked by: Pam j
There is no need for it to be secured to the foundation. The weight of the flooring will hold the underlayment in place. The seams need to be sealed, but this product has a built in lip and tape to make that easier and the edges need to be taped down to create a full moisture suppression system, but you do not need to secure anything other than the edges to the foundation.
