Rising Damp

Rising dampness is moisture that is soaking up a wall or floor from below the ground.

Moisture will travel upwards against gravity through porous material via a process called ‘capillary’.

Capillary penetration of moisture from the ground up through concrete, floor or masonry is known as "rising damp" and is determined by the shape and porosity of the construction materials through which this penetration takes place.

Rising damp will spread upwards and laterally.

Left unprotected, rising damp will rarely reach a height of more than 1.20m.

Most Common Cases

  • Bridging of existing damp proof course ( ex: patio installed over damp proof course)
  • No damp proof course in the property.
  • Water leak under floor.
  • Problems can arise when houses originally built with a damp proof course have been modified. This could be a raised patio has been installed and therefore breaching the damp proof course or the floor ventilation has been reduced or blocked.

Rising damp can also result in the decaying of skirting boards / timber flooring.

Two lines of defence to prevent rising damp are

  • Effective damp proof course installation
  • Adequately ventilated timber suspended ground floors
