Pavelock Sand 20 Kg

Product Description

Pave-Lok is a lightly bonded jointing sand specially formulated to allow rapid filling of vertical joints between segmental pavers. We recommend use on flexible pavements.

Features & Benefits

  • Helps retain integrity and stability of joint.
  • Resists wash out after 30 minutes setting.
  • Retards weed growth.
  • Is quick and easy to apply.
  • Minimises wind-blown joint erosion.


• Initial Set: Pave-Lok will Gel Set just 30 minutes after being wet. This gel set is strong enough to resist wash out by rain.

• Final Set: For Pave-Lok to become fully bonded it must dry out. The rate that Pave-Lok dries is dependant on 2 factors.
1. The drainage of the base. For best results the base should be permeable (eg sand), and have a drain so that excess water can escape.
If the base is concrete and bunded, rain water will be trapped and drying of the Pave-Lok will be very slow.
2. The weather conditions. In hot dry conditions the Pave-Lok will set within a few days.

Strength of Bonding
• PaveLok is a lightly bonded sand. A thin section of fully bonded sand can be snapped in ones fingers. PaveLok should not be used for structural construction.

• Pave-Lok is designed for flexible pavements. This means that the bond between the paver and the Pave-Lok is not strong, ensuring that if the base moves there will be many small “cracks” between the Paver and the Pave-Lok instead of a few large cracks across the Pavers and a mortar.

Upon the addition of water a white stain (efflorescence) can appear on the pavers. This efflorescence is the precipitate of fine white crystals (salts) and can come out of the paver or rise up with the base water. In the short term this stain can be removed with soapy water, but with rain new salt will likely be deposited. To negate this it is recommended that the pavers are sealed prior to soaking with water and that washed sand is used for the base.

Pave-Lok is suitable for use in the following areas:
• Driveways
• Footpaths
• Sloping sites
• Roadways/Airport standing areas (where designed)
• Where there is heavy traffic movement
• Where mobile vacuum sweepers are used
• In high wind areas
