Product Details

SAMAC De-Bonding Sleeves are designed to allow controlled movement within masonry and concrete structures, particularly at expansion and movement joints. Fitted over plain-ended wall ties or connecting ties, these sleeves isolate the bond on one side of the tie, enabling the structure to expand and contract without inducing stress or cracking.

Manufactured from durable, corrosion-resistant polythene or PVC, de-bonding sleeves provide a reliable solution for accommodating thermal movement while maintaining lateral restraint. Commonly used in cavity wall construction and concrete slab joints, they ensure that ties can perform their structural role without restricting necessary movement. Their simple push-fit design allows for quick installation on site, making them an essential component for compliant movement joint detailing.
