• Allproof Industries' commercial linear drainage is the ideal solution to all heavy duty channel requirements
• Available  rated from load class A to E

Design requirements

• PC is the ideal solution to all heavy duty channel requirements. Available in a range of widths, depths and grate options rated from load class A to E.
• All channels and grates come as standard with lockdowns to secure the grates and prevent any damage through movement. Security lockdowns may be available depending on system set up and project requirements, please contact Allproof for more information.
• Grates from this range can be utilised on other systems manufactured by Allproof Industries allowing designers to create consistency throughout their project.
• The system design accommodates runs of up to 43 metres, terminating at a sump. A mirror image can then be run in the opposite direction, resulting in maximum length of 76 metres between sumps. Overall system length is unlimited, dependent on required flow rates or other constraints
• On site mitre cuts are used to form corners, junctions and irregular lengths
• Joints can be sealed with suitable flexible sealant if required
• Outlets are achieved by utilising pre marked knockouts
• Allproof supply a wide range of grates to meet durability and capacity requirements. These include stainless steel, galvanised steel, glass filled nylon and cast iron

• Maximum length of 76 metres between sumps
• Overall system length is unlimited — this may be reduced dependent on required flow rates or other constraints

Installation requirements

• A minimum concrete surround is required to meet load capacity requirements, please see documentation available on the website allproof.com
• Channels are set to height on a bed of concrete to achieve required embedment and finished paving height
• Allproof suggest that site concrete is used to haunch the channel into position and prevent movement during concrete placement
• It is important to support the channel from the weight of the setting concrete by having either the original grates, or appropriate bracing in place. Protect grates from concrete contamination during installation by wrapping in plastic or masking tape. Alternatively, timber infills to match grate width can be installed during concrete pour to maintain channel design width
• Chemicals used during installation and finishing may react with a galvanised edge and/or grates, please ensure this has been catered for or a stainless steel finish may be required
