Biosand Technical Specification

Biosand, basically, is a unbound joint filling material for residential pavements/patios. An added feature of weed resistant is a fantastic addition. Every granule of sand is covered to raise the acidity of the product to point, stopping weeds.

How to:-

  • The empty joints should be completely filled with the BioSand to a level of 2mm below the surface of the paving on the new pavement.
  • On existing jobs, remove any existing weed growth and plants along with any existing jointing sand. Clean completely and allow to dry.
  • Jointex BioSand is an RTU (ready-to-use product). No mixing just open the 20Kg bag then pour over the pavement to be treated and filled. Brush carefully across the patio/pavement and of course fill the joints.
  • Fill to 2mm under the surface, use a compactor tool to settle, gently with a cushion base added.
  • Then brush away excess material, must not be left.
  • Over the next few days/weeks keep the joints topped up, they will settle completely in time, ensure to keep some biased spare for this.
  • Handy hint – allows apply in dry weather conditions
