Tournesol Siteworks’ standard pots & planters are designed to be used with drain holes. When a container needs to be watertight, we recommend waterproofing the interior. Our TourneSeal coating system is liquid applied, elastomeric waterproofing material, designed to seal the pot. While we water test every planter coated with TourneSeal, best practices (and our warranty) demand that the installing contractor field test with 6” of water to confirm the absence of installation or shipping damage prior to planting. Bioretention Planters
All of our pots & planters are designed to be used with drain holes to ensure long-term plant health. Typically, our FRP pots are delivered without drain holes to allow the contractor to field verify the correct location prior to drilling. Tournesol Siteworks is pleased to pre-drill drain holes in either GFRC lightweight concrete or FRP fiberglass pots when requested by the customer. Standard drain hole configurations (see below) are done free-of-charge at the factory. For unique configuration hole sizes or quantities, please speak with your salesperson. Note: All dimensions are approximate and the location of drain holes can vary +/- ½”; standard drain holes are 1-5/8” Dia.
