Recently, polymeric sand has been a hot topic of discussion. Polymeric sand is a new item that has been incorporated in the brick paving industry. It is a high tech mixture of sand and cement additives. It is an ideal option for filling joints between pavers. This type of sand hardens almost like grout between the bricks. It keeps the pavers in place better by binding the pavers together. It is better able to handle water and outdoor elements. It also assists in the prevention of weeds and bugs.
Polymeric sand is now available in a variety of colors specifically designed for different size, thickness, and spaced pavers. Keep in mind that polymeric sand might not be right for every project and needs to be used with care to prevent hazing on brick surfaces. Often, polymeric sand is used in substitution of a brick sealant which also helps to lock the joining sand between the brick pavers. Brick sealant, when used with polymeric sand, can cause a chemical reaction and stain the brick. Always seek the advice of a paving expert when considering polymeric sand or sealant for your brick pavers. If you decide to sand or seal your pavers it is critical that you understand and follow the directions exactly to prevent damage to the pavers.
