Application

The Radmat range of SWB Blue Roof Geocells provides attenuation as part of a Blue Roof system that is designed to manage and control incident rainfall at a rate in line with the SuDS strategy or the attenuation requirements for a development.

Description

Manufactured from polypropylene SWB Blue Roof Geocells are load bearing modular units that are clipped together to form a single- or double-layer attenuation cell that is wrapped in Radmat G12 Geotextile Filter Fleece.


Features and benefits:

  • Used in conjunction with rainwater outlet restrictors to control discharge, the Blue Roof is designed to be half empty within 24 hours.
  • SWB Blue Roof Geocells can be finished with a green roof, paving or rounded ballast as stated below. Where a support system is being used to support roof mounted plant or equipment each foot of the support system must be placed on a 1 x 1 metre spreader plate so as to ensure load distribution.
  • Green roofs can be installed over Radmat MedO D25, D40 or D80 reservoir/ drainage boards can be installed directly onto the Radmat G12 geotextile.
  • Rounded ballast should be installed over Radmat DM12 drainage board to prevent the rounded ballast penetrating the Radmat G12 geotextile when trafficked.
  • Bedded paving should be installed over Radmat DM12 drainage board to prevent damage to the Radmat G12 geotextile when installing.
  • Paving on supports should be installed on paving supports with a minimum 200 mm diameter base.

Installation

Manufacturer's standard.

Guidance for specification option:

  1. Install Radmat G12 Geotextile Filter Fleece over the roof surface and up all upstands, ensuring enough length is left around the installation for the G12 to wrap up the sides of the SWB Geocells, and enough to overlap a minimum 150 mm onto the top of the SWB Geocells.
  2.  Lay SWB Blue Roof Geocells, clipping adjacent panels to each other using the SW Cross Connectors ensuring each SWB Blue Roof Geocell is correctly oriented for the clips to meet. (This is also the jointing method for a 2nd layer of SWB, SWG are connected with a shear connector.)
  3. Cover with Radmat G12 Geotextile Filter Fleece ensuring minimum 150 mm overlaps.
  4. Immediately cover with the specified roof finish (green roof/paviors/ballast).
