• 120mm Length: Ideal length to cover the portion of the tie bar within the vertical expansion joint, ensuring effective debonding.

• Essential for Movement Joints: Used specifically at expansion joints to allow controlled thermal and moisture movement in brickwork and blockwork.

• Prevents Mortar Bonding: The plastic material prevents the mortar from adhering to the wall tie on one side of the joint, enabling free movement.

• Durable Plastic Construction: Made from resilient plastic, these sleeves are designed to withstand being encased in mortar during construction.

• Pack of 250: Supplied in a trade pack quantity, offering an ample and cost-effective supply for professional builders and masonry contractors.

Description

This pack contains 250 plastic Movement Tie Debonding Sleeves, which are crucial accessories for use with plain-ended movement ties in masonry construction. Each sleeve measures 120mm in length and 20mm in width. The sleeve is placed over the tie bar where it crosses the vertical movement or expansion joint. Their function is to prevent mortar from bonding to the tie on one side of the joint, effectively 'debonding' that section. This allows the masonry to expand and contract horizontally due to thermal or moisture changes without restraint, preventing undue stress and subsequent cracking in the wall. They are essential for ensuring the longevity and structural integrity of masonry movement joints.
