  • Backing plates for pump connections
  • Bulkheads for submersible or external pump plumbing
  • Fold-out anchor flaps with punched glue points

Three Color Options:

  • Tan: Blends with natural stone, sandstone, and warm-toned hardscape
  • Grey: Complements concrete, bluestone, and cool-toned materials
  • Black: Creates depth, hides water line, works with any color scheme

Compatible With:

  • Atlantic Formal Spillways
  • Atlantic WaterWalls
  • Atlantic Wall Spouts
  • Garden block wall installations
  • Engineered stone systems
  • Custom hardscape water features

Pump Connection Options:

  • Submersible pumps: Install pump inside basin, plumb through bulkhead
  • External pumps: Connect external pump to bulkhead from outside basin
  • Cord pass-through: Use Atlantic Cord Seal Fittings to pass electrical cords through liner

Important Notes:

  • Perfect for open basin applications requiring visible water reservoir
  • Not recommended for Colorfalls installations unless used with FiltoClear filter
  • Fits surrounds up to 8 feet wide
  • For closed basin systems, consider Atlantic rigid basins or Basin Kits

Note: Flex Hardscape Basins are designed for open basin installations where the water surface is visible. For Colorfalls (LED spillway) installations, use with a FiltoClear filter to keep water clean and clear. For closed basin systems with splash mats and rock cover, Atlantic rigid basins or Basin Kits may be more appropriate.

Frequently Asked Questions

Q: What's the difference between a Flex Hardscape Basin and a rigid basin?
A: Flex Hardscape Basins are flexible PVC liners that conform to your hardscape installation—they're ideal for open basin applications where you want a visible water reservoir integrated into your wall structure. The flexible design allows you to create custom shapes and sizes up to 8 feet wide. Rigid basins, on the other hand, are pre-formed hard plastic reservoirs with fixed dimensions—they're better for closed basin systems where the basin is hidden under a splash mat and decorative rock. Flex basins give you more design flexibility, while rigid basins offer easier installation and built-in filtration (Matala mats).

Q: Why aren't Flex Hardscape Basins recommended for Colorfalls without a filter?
A: Colorfalls are LED-illuminated spillways that create stunning nighttime displays, but the lighting makes any debris, algae, or cloudiness in the water highly visible—it literally spotlights water quality issues. Open basins (like Flex Hardscape Basins) expose water to sunlight, leaves, and debris, which can quickly make the water look unappealing. Without a FiltoClear filter to keep the water crystal clear, your beautiful Colorfalls display will be diminished by murky water. For Colorfalls, either use a FiltoClear filter with your Flex basin, or choose a closed basin system (rigid basin with splash mat and rock cover) that hides the water.

Q: How do I install the anchor flaps and secure the liner?
A: Installation is straightforward. First, position the Flex Hardscape Basin in your hardscape structure with the basin sitting where you want the water reservoir. The fold-out anchor flaps extend outward from the basin edges. Fold these flaps out flat and position them where your capstones will sit. The flaps have punched glue points—apply PVC liner adhesive or construction adhesive at these points to secure the flaps to your hardscape base. Then install your capstones on top of the flaps, sandwiching and sealing the liner in place. This creates a watertight seal and prevents the liner from shifting. The welded corners mean you don't have to fold or pleat material—it lays flat and neat.
