Point V Channel Drainage
Let us explain
Point Drainage

Surface water clearance

  • Intercept performance only at gullies

Installation

  • Excavation may be required from a minimum of 1.0m to 5.0m at the outfall of large sites, disturbing lower sub-soil layers which may require additional ground engineering consultation. Large quantities of spoil resulting from excavation, with consequent Landfill Tax costs
  • Large quantities of pea gravel required as bedding and backfill
  • More pipework, manholes, gullies and rodding points required
  • Excavation support required in deep trenches, planking, strutting and shoring
  • Complex final falls required to ensure effective clearance of surface water, each creating a dish to drain to gully

Aesthetic appearance and environmental performance

  • Less comfortable/harder work to walk, drive or push wheeled vehicles, trolleys or wheelchairs across

Channel Drainage

Surface water clearance

  • High intercept performance across total length of channel run; reduced occurrence of ponding or streaming across site; higher capacity than similar diameter pipes

Installation

  • More concrete needed for bed and hauching
  • No pea gravel required as bedding and backfill
  • Excavation is seldom more than 500mm below the finished paving level. If the reduced formation level of the site is 500mm or lower, extra excavation may be needed
  • Minimal interference with existing services due to shallow excavation
  • Minimal spoil to cart away (Landfill Tax)
  • Easy to achieve required levels / falls through following correct installation procedures
  • No planking or strutting
