Movement joints are designed to relieve or absorb anticipated movement between structural elements, which are generally caused by thermal expansion/contraction, settlement, load transfer, dead loads and at times even seismic activity.
Movement joints are dynamic, and will be subject to horizontal (expansion/contraction), vertical and shear movement. Therefore, before selecting the most appropriate movement jointing system, it is important that the movement criteria of the joint is known engineer to ensure that the proposed system accommodates all the predicted types of movement.

MultiJointMultiJoint is a closed cell, cross linked Ethylene Vinyl Acetate (EVA) copolymer waterproof foam, available in a wide range of sizes. The product is installed into joints using a two-pack, solvent free, modified epoxy adhesive, ie: MultiJoint Adhesive.
CementjointCementjoint is an advanced, elastomeric, highly tear resistant, breathable, composite waterproof tape. When embedded in Cementseal, it gives a highly flexible, impermeable seal over 'live' cracks and expansion/construction joints.
