Akwaseal pond liner consists of bentonite encapsulated between two geotextile layers with a flexible membrane liner laminated to one of the geotextiles. The result is an easy-to-install, self-healing, self-seaming liner requiring little maintenance. The swelling properties of the bentonite clay and cushioning of the textiles eliminate the need for seam welding and underlayments.
