Set Your Paving Stones for Long-Term Success

Polymeric sand is a unique material that is used to strengthen the connections between your interlock or flagstone projects. It is a critical element in any hardscape project, and should not be overlooked. It requires a small investment and will be the key to increasing the longevity of your landscape. As a bonus, polymeric sand prevents the growth of weeds between your interlock and eliminates joint erosion. Polymeric sand is reliable for a variety of applications including flagstone and pavers used in poolscapes, patios, driveways, and walkways. It is available in grey and beige colours in regular and high-performance options. High performance poly sands are ideal for poolscapes, driveways, and high traffic areas. 

How it Works

Polymeric sand is spread like normal sand but, once set with water, the individual sand particles bond to form a solid joint between patio stones and pavers. It is a cement-based product that is made to expand, contract, and re-heal itself. Unlike other joint filler options, poly sand stands up to the test of time!

Installation Instructions

Polymeric sand is installed in 3 easy steps!

Step 1:Spread

To begin, spread the polymeric sand evenly in small sections at a time. Use a tough-bristle street broom to fill the joints completely.

Step 2:Compact

Next, pass a protected compactor plate or paver roller over the entire surface to properly compact the sand. Once the sand has been compacted for the first time, repeat steps 1 and 2 until the joints are filled completely. Proper compaction will not allow a finger to sink into the joints. Before moving on, remove excess sand from the surface using a broom.

(Ask us about polymeric sand products that do not need compaction!)

Step 3:Activate

To activate the poly sand, quickly shower the surface with a water hose nozzle. Always start from the bottom of the slope and work in sections of 200 sq ft. at a time. 

Immediately after this, wet the same section for an additional 30 seconds to saturate the joints. Water accumulation at the surface will be your cue to stop showering the sand. 

Once the installation process is finished, do not allow any vehicular traffic for a minimum of 48 to 72 hours to allow the joints to dry out completely.
