Should I leave a gap (grout lines) between my Travertine Pavers?

Question: Do I need to leave a gap (grout line) between the Travertine Pavers? 

Answer:
No, you do not need a gap (grout line) in between the Travertine Pavers. Install them right up against each other. Once the installation is complete, sweep polymeric sand into the joints and hose the deck with water afterwards. This will harden the polymeric sand and prevent weeds from growing through the cracks.
