Poly Sand Compact

Polymeric Sand Will Ensure a More Durable Brick Paver Patio, Walkway or Driveway

By Mark J. Donovan




Poly sand compact, or Polymeric sand, is used in building concrete paver, brick or stone patios, walkways and driveways. It is used to bind or interlock the concrete paver, brick or stones together to produce a more durable patio, walkway or driveway surface. Polymeric sand is brushed in between the paver/brick joints and then watered down to activate the polymer binder.

Once activated the poly sand compact tightly interlocks the pavers or bricks to prevent washout, insect damage and weed penetration.

Traditionally landscapers would sweep torpedo or silica sand into the joints to interlock the pavers, bricks or stones.

In some cases a sealer was used to help hold the upper layer of sand in place in between the joints and to prevent wash out, insect damage and weed growth. However, most of these problems would still crop up over time, particularly after a strong rain storm.

What makes Poly sand compact different and better is that it is comprised of crystalline silica and quartz, along with a polymer ingredient. After the poly sand compact is swept into the seams and activated with water it binds the silica and quartz throughout the entire depth of interlocking material. As a result, it creates a much more durable brick or paver walkway, patio or driveway. In addition, it helps prevent water from filtering down underneath the bricks, stones or pavers, and compromising and deforming the overall integrity of the patio, walkway or driveway.  Polymeric Sand compact is a key ingredient in building a lasting patio with concrete patio pavers.

Consequently landscapers have been switching to polymeric sand to lock in brick, pavers and stones. Though it costs quite a bit more than silica or torpedo sand, landscape contractors end up saving time, money and hassles in the end. One of the most common frustrations with landscape contractors is having to run back and repair a freshly installed patio, walkway or driveway due to a heavy rainstorm that shortly followed the installation and washed out the joint sand.

As previously mentioned poly sand compact is pricey. Polymeric sand costs approximately 3 times as much as silica or torpedo sand. However, considering the fact how little is actually used to interlock the brick or paver joints, it is minimal to the overall cost of the brick or paver project and well worth the investment.

The alternative to not using poly sand compact is ultimately much higher and more frequent repair costs due inevitably to rain water, ant and weed damage.

So the next time you’re installing your own paver or stone patio, walkway or driveway, or are getting bids from landscape contractors on installing it for you, consider using or asking about poly sand compact.
