Application instructions



Where to form an expansion joint in in situ concrete, Isoplaat shall be placed against the shuttering on the concreting side before the pour begins. Copper nails may be used to prevent displacement in joints in suspended slabs.

Joint sealing

A joint sealing slot can be formed by placing a removable timber former on top of the Isoplaat. Alternatively Isoplaat can be installed to the full depth of the slab and cut back to the required depth subsequently using a power brush

machine. This latter method is generally used for housing estate roads, which cannot be cleaned and sealed until building has finished. Isoplaat should be tamped down to ensure that it fills the joint completely and provides continuous support for the joint sealant.
