How To Avoid Weeds In Pavers
What happens here
Understanding why your patio will remain weed-free and how to maintain it ensures long-term success. The three primary reasons for weed prevention are: 1) **Soil Compaction**: The subsoil is so dense that roots cannot penetrate it. 2) **Geotextile Fabric**: This physical barrier blocks roots from reaching the subsoil. 3) **Packed Paver Joints**: The joints are completely filled with hardened polymeric sand, leaving no space for weed seeds to germinate or roots to establish. For maintenance, over a period of 5-8 years, polymeric sand may erode from the joints. When this occurs, pressure wash the affected joints clean, let them dry completely for 24 hours, and then refill them with fresh polymeric sand and activate it as per the initial installation process. This simple maintenance keeps your patio pristine.
Goal: Ensure long-term weed prevention and know how to maintain the patio
