How do I joint concrete slab paving laid using the unbound method?

Concrete slab paving installed unbound is jointed with kiln dried jointing sand. The sand is brushed and vibrated into the joints using a plate compactor.

Important: The paved area should not be cleaned by vacuum road sweepers for a minimum of 3 months. This prevents loss of jointing sand and allows sufficient time for the sand to self-stabilise. If necessary, the jointing sand can be stabilised immediately by using a sand joint sealant.
