The Common Issues with Paving Grout

Paving grout is an essential element in a paving system. However, like any other construction material, it is not without its challenges. Understanding these common issues with paving grout and knowing how to address them can significantly enhance the durability and visual appeal of your paved surface.

Cracking or Shrinkage

One of the most common issues with paving grout is cracking or shrinkage. This issue often arises due to temperature fluctuations, moisture changes, or inaccurate installation.

Repairing failed cement grouting can seem like a daunting task, but with modern technology like ROMEX® D1, the process is simplified. ROMEX® D1 is strong and durable but most importantly, it is flexible which means it expands and contracts with the pavers.

Discolouration and Staining

Discolouration and staining are other common problems. The usage of high-quality grouts such as ROMEX® D1, ROMEX® Profi-Easy, ROMEX® NP Jointing Sand, and appropriate sealing can mitigate discoloration. For existing stains, follow cleaning techniques recommended by the manufacturer or consult professionals if necessary.

Paving Sand That Washes Out

Paving grouting sand might be washed out by stormwater, flooding, and gutter downpipes amongst others. Contractors generally use cement and plaster sand to compact the grouting sand, however this doesn’t last. ROMEX® NP Jointing Sand is the ideal product as it contains a polymeric binder that binds the jointing sand particles together while remaining flexible.

Preventing these common grouting issues begins with choosing the right product and ensuring an accurate installation. In summary, although cracking, shrinkage, discolouring, and staining are common issues associated with paving grout, they can effectively be managed with the right ROMEX® products.
