Question: I like the way travertine pavers look ungrouted. My husband likes to water my garden and also the patio area, often. My concern is if the travertine will lift or get damage from being constantly watered. We are sealing it, however, my installer suggested we grout it. I'm confused. I really like how it looks without any grout.
Answer: There is no reason to grout the travertine pavers. They are used primarily as pool pavers with no grout. After installation, it is suggested that polymeric sand is swept into the joints to prevent weeds from growing through.
Sealing travertine and using polymeric sand should be sufficient.
