Expansion Joint System Kit

The Expansion Joint System is a ready-to-install kit that forms a precise 10 mm movement gap in a 100 mm concrete slab while transferring load smoothly across the joint. Each 3 m steel profile comes pre-drilled for Connolly Universal Dowel Sleeves, so dowels slot in straight and true with the patented twist-fix action—no drilling, packing, or alignment jigs required.

Features + Benefits:

Complete Joint in One Kit: Expansion joint, galvanised dowels, sleeves, pegs, and wedges arrive together—just set and pour.
Twist-Fix Sleeve Connection: Patented interface locks UDS sleeves to the profile instantly for perfect dowel positioning.
Versatile Dowel Capacity: Pre-formed holes accept round dowels to Ø30 mm or square dowels to 24 mm, future-proofing the slab for heavier loads.
Corrosion Protection: 12 mm × 300 mm galvanised dowels resist rust and preserve joint performance in wet or corrosive environments.
Fast, Repeatable Setup: Pegs and wedges hold the profile at the correct height and line, cutting installation time and re-work.
Product Uses: Ideal for expansion gaps in industrial floors, warehouses, distribution centres, hardstands, and any 100 mm-thick slab requiring controlled movement and positive load transfer.
Pack Size: One kit contains — 1 × 3 m steel expansion joint profile, 9 × 12 mm × 300 mm galvanised dowels, 9 × Universal Dowel Sleeves, and a 4-pack of pegs & wedges. Profiles also available (separately) for 120–300 mm slab thicknesses.
