GftK’s vdw 870 Paving Jointing Sand Stabiliser
GftK’s vdw 870 Paving Jointing Sand Stabiliser is specifically designed to penetrate into the sand and bind the individual sand grains together between so-called ‘flexibly’ laid paving stones or blocks. ‘Flexibly laid’ simply means that the blocks are laid on a bed of compacted sand / aggregate and not laid ‘rigidly’ into concrete or mortar. The use of the GftK’s vdw 870 Paving Jointing Sand Stabiliser effectively stabilises these sand filled joints, which very significantly increases their resistance to dispersal, and very significantly reduces the jointing sand being extracted by weathering and light domestic cleaning operations, such as vacuum sweeping and controlled power washing, plus this also increases resistance to entry for plant seeds, plant roots and burrowing insects such as ants. Therefore GftK’s vdw 870 Paving Jointing Sand Stabiliser is less penetrative, but much tougher and flexible, hardening to be more elastic than surface sealers, in order to bind the sand particles together and enable the filled joints to accommodate the natural flexing and movement of flexibly laid block paving.
