I just reset my walkway pavers (S+H), I had to do this because of mole tunneling beneath. Do I have to fill in “grout” spaces with sand? I kind of like it bare.
Moles and other animals can be quite destructive for landscaping. Our advice would be to to fill in the joint 1/2-2/3 with polymeric sand or brick sand just to keep insects or even the moles out.
