frequently asked Questions

A high-quality grouting serves different purposes. For one, the plates remain continuously at the same distance. In addition, there is a visually appealing overall picture. The joints protect the panels and reduce stress.

Concrete is not a suitable material. The lack of elasticity can cause cracks over time. In the worst case, the terrace slabs suffer irreversible damage. Joint mortar should therefore always be elastic.

In terms of costs, the sand can convince. High-quality grouts cost significantly more money. In addition, the rework is more complex. In the case of joints made of sand, sweeping again in the desired grain size is sufficient.

Regular refilling is required when introducing sand. In addition, insects are much more active in the loose soil material. Weeds grow through the sand and collect in the joints of the patio tiles. Sand is relatively elastic, so the floor tiles can slip. Alignment correction is required over time.

For stopping in, grit with a grain size of 1 to 3 mm is recommended. The fine grit can be swept into all joints. Make sure that it is basalt chippings so that the edges get caught.
