Frequently Asked Questions

1. How does polymeric sand work?

Polymeric sand is applied into the crevices between pavers or stones. Water is then added to the binder, which hardens over a given period. The sand acts as a strong binder, covering and stabilizing the pavers. It also seals the cracks, minimizes weed growth and damages caused by insects, does not erode, and forms a smooth and long-lasting bond.

2. What is the difference between jointing sand and polymeric sand?

Joint sand is used as an initial binder of paver stones to form an interlocking system.  Polymeric sand provides stability to the pavers and keeps the stones from moving with pressure. It also seals cracks and cervaces and keeps water from seeping under the pavers.

3. Can water drain through polymeric sand?

Polymeric sand, besides creating a deterrent for insects and weed growth, allows excess water to seep out effectively.

Polymeric sands are used to stabilize and bind the stones and tiles on the floor to ensure there are no unnecessary gaps or cracks that can lead to weed growth, insect infestation, and further damage to the foundation. The best polymeric sands listed here can help you create impermeable blocks with maximum durability and flexibility and save you time and energy while performing the task. When choosing one, make sure to consider the quality, drying time, resistance, color, and ease of use.
