To avoid weeds and displacements in the paving, the joint must always be filled to the full height of the joint edge and be completely free of soil and other organic material. The paving is cleaned with a stiff broom and the joints are refilled as needed. Moss and algae can be removed by suitable means. Extreme weather conditions can cause white deposits (efflorescence) in the joints and on the edges of the paving stones. However, they are usually washed off at the next rain shower. The deposits can also be removed by regular cleaning of the stones. We have added a mineral additive to DANSAND ® joint filling sand, DANSAND ® Stone dust and DANSAND Kerama ®. The mineral has a naturally high pH value, which creates a nutrient-poor environment in your joints. The weed seeds dry out and can neither take root nor germinate.
