For years, paving stones have been increasingly used again for inner-city streets, public paths and squares as a floor covering. Unfortunately, this has some massive disadvantages in addition to the visual enhancement, because the joint is washed out by weeds, rain and other natural influences. Mechanical cleaning by suction sweeping machines also weakens the joint. Deeply washed-out joints are not only a reservoir for all kinds of impurities, but also represent a potential for accidents that should not be underestimated.

Due to the practically non-existent joint, the paving stone can come loose and create serious tripping hazards. These weak points are eliminated by our paving joint mortar systems. Gremmler paving grouts can be used for both old and new paving made of stone of almost any size.
