Selection Criteria for Paving Jointing

The Key Criteria for the selection of the right Paving Jointing Mortar / Paving Grout for a project must be defined and detailed / specified as soon as possible to avoid future problems in application (e.g. with delays due to wet weather), or eventual disappointment will follow in the paving performance and its durability (e.g. with damage from cement cracking , frost, burrowing insects or weed growth etc.).

The most appropriate Paving Jointing Mortar or Paving Pointing or Paving Grout, as they are also sometimes known, should be selected according to:

The Type of Paved Area i.e. Patios & Paved Pathways, Paved Driveways & Car or Truck Parking Areas, Paving around Commercial Developments, Town Centre Pavements & Street / Highway Paving works, Heritage & Historic Paving Areas


  • The Paved Area’s Traffic Exposure e.g. Pedestrian, Light Vehicular, Frequent Vehicular, or subject to Heavy Goods Vehicles & Commercial Traffic.
  • The Paved Area's Environmental Exposure e.g. Cleaning with Mechanical Street Cleaning machines, high pressure water jetting, the use of de-icing salts, boring insect and weed growth prevention.
  • The Application Conditions i.e. Weather conditions (wet or dry?), residual moisture conditions (possibility of water in the joints?), temperature and variations (high or low?), Method of Application (trowel or slurry?), dust and dusting restrictions, waste run-off restrictions (preventing entry to drainage system etc.)
  • The Size and Type of Paving e.g. Small Format Paving, which is regarded as joint dependent - Such as stone setts, cobbles and blocks; or Large Format Paving, which is regarded as bedding dependent - Such as stone slabs and flags, plus the units surface profile and ease of cleaning and any sensitivity to grout staining.
  • The Specific Joint Dimensions i.e. the Joint Depth and also very importantly the Joint Width, together with the variation of these across the paving.
  • Any other relevant local requirements i.e. Closure time available and the finished mortar permeability, which is normally assessed in terms of litres per square metre per hour (l/m2/hr) as may be required for local SUDS regulations. The Jointing material colour matching / contrast and consistency required etc.
