Flexlock Ultra


Flexlock Ultra Sand is a unique mixture of polymer binders and calibrated sand available in Sandy Beige and Graphite Grey. The installation of Flexlock Ultra Sand is almost identical to using regular paver joint sand except for the application of water. Once Flexlock Ultra Sand sets, it becomes very firm and locks between the paver joints while still retaining flexibility and providing a long lasting, durable jointing material. Flexlock Ultra Sand is recommended for a variety of uses including pool decks, patios, footpaths, driveways, parking spaces, pavements etc.
