Sika Sarnafil Inc.
website | Company information

Sika Sarnafil’s G476 waterproofing membrane is now available in a six-and-a-half foot wide self-adhered format. The membrane is a 120-mil thick composite sheet composed of a 60-mil vinyl waterproofing membrane and an integral 60-mil non-permeable closed cell foam backing layer coated with a pressure sensitive adhesive. The flexible foam backing layer conforms around minor irregularities in the substrate and provides a cushion for the waterproofing membrane.

The pressure-sensitive adhesive provides a tenacious bond between the membrane composite and substrate to mitigate potential water migration under the sheet. The system’s self-adhering component is designed to increase installation efficiency, according to the company.
