A facility where construction and demolition waste is received for sorting, processing, or compacting before being transported to recycling centres, treatment facilities, or landfill sites, ensuring efficient waste management within the self-build property sector.

Water Hammer

A pressure surge or shock wave in plumbing systems caused by the abrupt stopping or changing direction of flowing water. This results in loud banging noises and can lead to pipe damage if not addressed, typically due to issues with valves or water flow.

Wayleave Agreement

A legal contract between a landowner and a utility provider granting permission for the installation and maintenance of utilities (like cables or pipelines) on or across the landowner’s property, typically involving compensation and terms of access.

Weathered

Referring to materials or surfaces that have been affected by exposure to environmental elements such as wind, rain, and sun. This can result in changes in colour, texture, or structural integrity, often aimed at enhancing drainage or resistance to the elements.

Weep Hole

A small opening, often found in masonry or brickwork, designed to allow moisture trapped within a wall or building structure to escape. This prevents water accumulation, reducing the risk of damage and promoting air circulation within the wall cavity.

White Land

A classification for land designated in planning contexts that has no specific development proposals or restrictions. It typically allows existing uses to remain unchanged, providing flexibility for landowners while limiting immediate development pressures.
