There is little that can be done in damp, shaded areas to prevent weeds from continuously growing. That being said, Techo-Bloc’s Stabilizing Sand allows very minimal weed growth between the joints. As for the shifting of the slabs, we test our products using saline tests rather than water tests. Our dry-cast paving stones are de-icing salt resistant and engineered to withstand the harshest climates. We're a Quebec grown company, we know how difficult Canadian winters can be. As such, each paver is designed to interlock with the pavers next to it, which creates a solid and sturdy surface that won't shift over time. Any well installed Blu 60 slab will be forever set in stone or, better yet, concrete.

what color coping/pavers are these? thanks

Hey Jess,

The pool coping is Bullnose in Champlain Grey and the slabs are Blu 60mm slate in Champlain Grey as well.

Hope this helps!
