Corodrain Roof Gutters

Abutment Soaker

Corodrain Abutment Soaker

Corodrain Abutment Soakers provide weatherproof protection between a pitched roof and a vertical wall abutment.  They are available lipped for fixing directly into the wall or unlipped for use with a separate flashing band.  Manufactured in GRP,  Corodrain Abutment Soakers are a tough and long lasting alternative to lead, and are cheaper, quicker to install and less prone to vandalism and theft. The bonded 25mm sanded strip give maximum mortar adhesion and the two water bars along the horizontal section prevent moisture entering the roof space.

Installation

PREPARATION
Prepare a space for the abutment soaker: Allow 100mm between the abutment and the ends of the tile battens. Fix another batten down the slope of the roof, level with and up against the ends of the tile battens, to support the abutment soaker along its length.    

POSITIONING
Place the abutment soaker with the flat surface vertical against the abutment and the profiled surface down onto the roof. Nail the abutment soaker to the supporting batten.

To span the length of the roof: if the gradient of the roof is 30 degrees or more, overlap the ends of each abutment soaker piece by at least 150mm, if the gradient of the roof is 29 degrees or less, overlap the ends by at least 225mm.
At the eaves, the abutment soaker can be extended up to 150mm from its supports to reach the eaves gutter. At the ridge use a lead saddle.    

FIXING
Lay tiles onto the abutment soaker, using a mortar bed on the sanded strip of the abutment soaker. The gap between the edges of the tiles and the abutment should be no more than 15mm. A cover flashing can be used if required.

For an Unlipped Abutment Soaker, weather the side abutment by covering the flat vertical surface of the abutment soaker with a step flashing.

For a Lipped Abutment Soaker, create a channel in the abutment wall for the lip of the abutment soaker to fit into.

For a Lipped Abutment Soaker, set the lip into the channel using a high quality external grade of mastic.

Properties

LEAD REPLACEMENT
GRP lasts as long as lead, is tougher, cheaper, more resistant to accidental damage, and is less prone to theft or vandalism. Using preformed GRP abutment soakers saves significant installation time over traditional methods. Roofers report elimination of many problems with valley troughs when changing from lead to CORODRAIN GRP. Coloured lead grey as standard (other colours available on request). 

DURABILITY
Made with high quality un-filled polyester resin with glass fibre reinforcement for maximum strength. A tough bonded melinex film gives excellent weathering performance. Minimum life of 30 years. 

MANUFACTURED IN THE UK
Manufactured to BS EN ISO 9001:2008 quality standard, at our automated continuous pultrusion plant in Coventry. All available from stock for rapid delivery to site.

NO MAINTENANCE
The inherent qualities of the materials make the soakers UV light and acid rain resistant, and the smooth surface finish inhibits the growth of moss, lichen and the build up of debris.
