Verified scope

What this product is.

CORE DRAINAGE CELL is a thin, interlocking void former used beneath podiums, roofs and planters or wrapped as a vertical fin drain. Water-management performance depends on the geotextile, falls, outlet and protective layers around it.

Applications

Where it can be considered.

  • Podium drainage
  • Green-roof and planter drainage
  • Horizontal landscape drainage
  • Geotextile-wrapped vertical fin drains
  • Wall, basement and sports-area interfaces
Limitations

Where judgment is required.

The cell does not create a drainage outlet; falls, discharge and overflow must be designed.

Use the drainage-cell sheet only; do not apply CORE DRAINBASE buffer-capacity figures to this product.

Waterproofing protection and roof/podium compatibility remain with the project designer.

Filter geotextile and cover layers must prevent fines entering the void.

Installation overview

Sequence the interfaces.

  1. 01

    Prepare and protect the receiving layer and confirm falls and outlets.

  2. 02

    Lay the specified geotextile and interlock cells using the pin-and-socket connection.

  3. 03

    Cut cleanly around penetrations without damaging waterproofing or adjacent layers.

  4. 04

    Wrap or cover with the specified overlapping geotextile to retain fines.

  5. 05

    Install the designed filter, protection and landscape layers without crushing or displacing cells.

Straight answers

CORE DRAINAGE CELL questions.

Can it be used vertically?

Yes. The current guidance includes geotextile-wrapped vertical fin-drain uses, provided discharge and protection are designed.

Is it the same as CORE DRAINBASE?

No. They are separate products with different dimensions, materials and performance data.

Does it protect waterproofing?

It may form part of a protected build-up, but the waterproofing designer must approve the protection, compatibility and load sequence.
