Types of Paving Grout
Paving grout plays a crucial role in the installation and maintenance of various types of segmented paving. Paving grout not only secures the pavers in place but also enhances the aesthetic appeal and functionality of the paved surface. There are various types of paving grout in the market for various applications. Understanding the distinct characteristics and uses is essential for selecting the right paving grout. In this article, we explain the different types of paving grout on the market.
The Different Types of Paving Grout
Sand Grouting
Sand is the most common, yet most misunderstood form of paving grout. In South Africa, there is very little specially graded sand available to use for joint pavers. Sand interlocks adjacent paving bricks by means of friction while spreading the load. Using the correct sand in itself will prevent sand from washing out and other possible problems.
Cement-based Grout
In South Africa, a mixture of sand and cement is often used to grout paving. This leads to endless problems as cement-based grout stains paving and it will almost certainly crack. It is not uncommon to see pieces of cement grouting breaking out in a paved installation.
Epoxy-based Grout
Epoxy-based grout consists of epoxy resin and hardener. It offers superior strength, chemical resistance, and stain resistance. This type of grouting is ideal for areas with high traffic and exposure to spilled substances. However, its application can be more complex and may require professional assistance.
Polymeric sand
Polymeric sand is made from a mixture of sand and polymer additives, polymeric sand creates a flexible yet firm bond between pavers. It is suitable for joint stabilization and weed prevention, making it a popular choice for interlocking and natural stone paving projects. Proper installation techniques, such as compaction, are crucial for optimal results.
