Newton Pipe Collar Self-Adhesive Surface Seal

The Newton Pipe Collar is a specialist, self-adhesive sealing component designed to provide a rapid and permanent watertight seal around service pipes that penetrate Newton cavity drain membranes. Circular in shape and highly flexible, the collar is manufactured from a premium butyl rubber base with a high-strength fleece backing. This design allows it to conform tightly to the pipe and the surrounding membrane, creating a robust gasket that prevents water or gas ingress at one of the most vulnerable points in a waterproofing system. Because it is self-adhesive, it eliminates the need for complex cutting or messy liquid sealants, ensuring a professional, clean finish that remains flexible enough to accommodate minor thermal expansion or contraction of the pipework.

Benefits:

• Provides a fast and reliable watertight seal around service pipe penetrations
• Features a high-tack self-adhesive backing for immediate bond to the membrane
• Flexible construction conforms easily to different pipe diameters and irregular surfaces
• Fleece-backed surface provides an excellent key for subsequent wall finishes or screeds
• Extremely durable and resistant to the damp conditions found in basement environments

Good to Know:

• The product is identified by the Newton product code A35
• Designed for use with standard service pipes (typically 110mm) but can be adapted for smaller diameters
• Surfaces must be clean, dry, and free of dust before application to ensure a permanent seal
• Often used in conjunction with Newton CDM Rope for double-layered protection around the pipe base
• Suitable for both internal and external waterproofing applications
