  1. I have these gaps between paving stones and between the stones and the elevation of the house. The ants and weeds start to grow through the gaps. I found some products recommended online e.g. Sika EBT but these don’t seem to be easily obtainable in Belgium. Any advice on how to fill this and what products to use? Thank you.
