HI- JOINT MORTAR is a rapid set joint mortar designed for the joining of pavements units constructed with clay, natural stone, granite setts, concrete flags, and paving bricks.


  • Rapid Setting
  • Chloride free
  • Excellent Bonding properties
  • Ready to use, only requires the addition of clean water.


Hi, Jointing Mortar can be used in the following applications:

  • Jointing of natural stone setts and slabs.
  • Joints to curbing.
  • Jointing of concrete flags.
  • Jointing of clay pavers.


Hi- Joint Mortar is available in  20kg bags.


Ensure the paving is free from any dust, dirt, or grease, presoaked, and have all ponded water removed prior to application. To overcome any potential segregation that has occurred during transit, thoroughly mix the maxi bag contents before us.

Hi-Joint Mortar should be mixed with approximately 3.5 liters of clean potable water, per 20kg bag of material, for 3-4  minutes to reach a lump-free flowing consistent slurry.

Do not remix or add additional water to the mix only enough material which can be placed within 10 minutes.

Pour the fresh mortar onto the prepared paved area and chase into all joints with a soft brush or squeegee. Ensure joints are full, allowing for settlement, and remove any excess material with the squeegee once joints are full.

Spray a mist of water onto the area at all times to aid the cleaning process. When the joints are sufficiently hard (this could be as soon as 15-20 minutes) remove any residual material with a constant flow of water and diagonal sweeping action.


Hi-Joint Mortar will keep for up to six months if kept in a dry store, up off the ground, and providing the bags remain sealed. High temperature and high humidity conditions may reduce the storage life of the product.


Hi-Joint Mortar contains cement powders which can be harmful to the skin. During use, avoid inhalation of dust and contact with the skin and eyes. Wear suitable clothing, gloves, eye protection, and respiratory protective equipment.
