The FinnJoint™ is a long term maintenance free alternative to joint sealants. The FinnJoint™ provides edge protection eliminating the need for rectification of spalled concrete edges and continuous replacement of sealants. All other products must be fitted after pouring. The FinnJoint™ consists of an anodised aluminium extrusion, a hydrophilic rubber gate seal, and nylon fixing tabs. It allows concrete slabs to shrink during curing without cracking, and services expansion and contraction due to temperature changes.
