Roof & podium drainage

Maintain a drainage route beneath compatible roof landscapes.

What it is

Roof and podium drainage uses CORE DRAINAGE CELL or CORE DRAINBASE to maintain a drainage void beneath podiums, terraces, green roofs, paving and artificial grass over waterproofed structures.

THE DRAINAGE PRODUCT RANGECORE DRAINAGECORE DRAINAGE CELL and CORE DRAINBASE create a drainage void beneath compatible roof, podium and landscape finishes.View CORE DRAINAGE

Suitable for

  • Podium landscapes
  • Roof terraces
  • Green roofs
  • Paving and artificial grass

Common applications

  • Sub-surface drainage

  • Landscape build-ups

How it works

  1. 01

    A protection and drainage layer moves water towards coordinated outlets.

  2. 02

    Geotextile layers filter and separate materials where required.

  3. 03

    The finish build-up is selected around falls, loads, thresholds and maintenance.

Before you specify

Waterproofing, outlets, loads and membrane compatibility must be coordinated by the project team.

Drainage products do not replace the roof drainage design.

Products in the build-up

These products may be used alongside CORE DRAINAGE, depending on the formation, loading, drainage and finish.

Questions

What does a roof drainage cell do?

A drainage cell maintains a sub-surface void that allows water to move towards coordinated outlets beneath a compatible landscape finish.

Does the drainage layer replace the waterproofing system?

No. The waterproofing, protection, outlets and membrane compatibility remain part of the coordinated roof design.

What information is needed for a roof or podium build-up?

Send the waterproofing system, falls and outlets, allowable loads, available depth, thresholds and proposed finish.
