Abstract: A method for heat sealing a portion of an upper heat sealable thermoplastic membrane to a portion of a lower heat sealable thermoplastic membrane which comprises placing a detachable stabilizer strip on the outer surface of the upper membrane over the over-lap seam portions to be sealed. The stabilizer strip must fully adhere or have mechanical contact to retain the dimensional stability of the upper membrane while maintaining the relative positions of the membranes. A hot air medium is directed between the upper and lower membranes thereby effecting a heat seal therebetween. Once the overlapped and sealed portions of the membranes are permitted to cool, the stabilizer strip may be removed.
