The soil was excavated and the interior of each planter box was cleaned. A synthetic rubber Hypalon liner was installed and mechanically fastened to the concrete. Several perforated drainage pipes were plumbed to the exterior to remove excess water from the soil. The entire box is now completely watertight and will last for 30 years or more without maintenance.
For the last 4 years, every experience with Ken and his team has been nothing short of fabulous. Even if tough situations arise, and they always do in my line of work with homeowners, his professionalism shines through.
