What Are the Problems With Polymeric Sand?

One of the main problems with polymeric sand is under-watering during the installation process. When polymeric sand isn’t properly watered, it tends to form a “crust” or hardened layer on the top, rather than fully bonding the joints. This can result in several issues. Firstly, if the sand only forms a crust, it doesn’t provide a strong bond in the joints, leading to potential erosion over time. The crust can break away, causing the joint to become loose and unstable.

Moreover, under-watering causes cracks and gaps in the joint. When the sand fails to fully bond the entire depth of the joint, it leaves empty spaces that can allow for movement and shifting of the pavers. This can result in uneven surfaces, trip hazards, and potential damage to the overall structure.

Another problem with polymeric sand is it’s susceptibility to extreme weather conditions. When exposed to excessive heat or heavy rainfall, the sand can become weakened and prone to erosion or washout. This can lead to the dislodging of pavers and a compromised stability of the paved area.

Furthermore, polymeric sand can be difficult to repair or replace once it’s fully set. If any issues arise with the joint, such as cracks or gaps, it can be challenging to address them without disturbing the surrounding pavers. This can result in additional costs and time-consuming efforts to rectify the problem.

Lastly, the effectiveness of polymeric sand may vary depending on the type of pavers and the specific installation conditions. It’s important to carefully follow the manufacturers instructions and consider the specific requirements of your project for optimal results.
