Prefer an open basin for your Scupper or Spouts? Our Flexible Basins are the perfect choice for custom block reservoirs up to 8 feet wide, especially in northern climates, where frostproofing masonry can be a concern. Available in tan and grey to match or complement block colors, these rip stop PVC reservoirs eliminate corner folds and wrinkles of makeshift EPDM constructs and come pre-punched for included bulkhead fittings, with 10″ backing plates for plumbing submersible or external pumps.
Flexible Hardscape Basins

TECH TIP
For best results, fill Flexible Basin with water before finishing off the surrounding walls with caps. You’ll be able to pull the flexible sides upwards and work out any wrinkles for the most attractive appearance before permanently attaching the top layer of wall blocks.
