This is an example of a grout repair we completed on a relatively new paver patio that was originally installed by another contractor. Unfortunately, the installer left excessively large joints instead of making the proper cuts to achieve a tighter, more professional fit. Large gaps not only affect the appearance of a patio but can also lead to ongoing maintenance issues as joint material washes out and weeds begin to grow. ​ At Boulder Brothers LLC, we recommend using premium polymeric sand whenever possible. While it costs more than traditional joint sand, it provides a stronger, longer-lasting bond when installed correctly. Proper installation is just as important as the product itself—the correct amount of water must be applied during activation to ensure the sand cures properly. When done right, polymeric sand can provide years of durable performance with minimal maintenance. Quality installation makes all the difference. Investing in proper craftsmanship from the beginning helps prevent costly repairs down the road.
