Polymeric sand is a special type of sand used in the joints of pavers. When mixed with water, it forms a strong, semi-flexible bond that holds pavers in place and offers several benefits. Firstly, it keeps your patio stable by preventing paver shifting. Secondly, it deters weed growth and deters ants from burrowing into the patio. Lastly, it enhances durability and longevity by preventing water seepage into the sub-base.
