Replace it with this beautiful paver walkway #sealcoating #diy #asmr #fyp #satysfying #landscape
How to build a paver walkway - Here we remove this old concrete sidewalk and replace it with this beautiful paver walkway. We install overlay pavers on the existing concrete porch. We also install edging stone blocks for the garden bed. This install was done on an open grade base and we used concrete as the edge restraint.
