Is All Sand the Same?

If you love to tackle do-it-yourself landscaping projects, you know getting the right materials is vital to obtaining the best results. The wrong grass type for your lawn can make it impossible to get the lush lawn you prefer or the incorrect fertilizer can do more harm than good. When a project calls for sand, the same is true. There are different types of sand that are best for certain applications. Knowing the difference can ensure you get the results you desire for your next project that calls for using sand.

Paving Stones

For sand to fill in around and under paving stone, you want a fine dust that will settle and compact quickly. A good choice for this project is granite dust that is easy to sweep into those cracks and will stay in place.

Leveling Lawns

When adding sand to level lawns in grass types that work best in a sandy soil, choose river sand.  Bermuda and Zoysia grasses are two lawns that require sand for the best results when leveling. Make sure to choose a well-screened river sand that will not add large chunks of gravel to your lawn.

Drainage for Soil

If adding sand to improve the drainage in your soil, river sand is best. 

Masonry Work

When adding sand for mortar when performing masonry work, a grittier white sand is a good choice. 

Sand Boxes for Play Areas

For a thick sand box for the kids, use white sand. This is also good for leveling property or landscaping areas.

Knowing the right type of sand to use is important since the consistency varies with the source. Talk to your landscape supplier before ordering sand for your project to ensure you get the right type for your project.

Polymeric Sand


Polymeric sand is the material used to fill the joints or gaps between stone or brick pavers in driveways, patios, and walkways.  Polymeric sand is designed to help hold stonework in place and keep it from shifting.  This resistance to shifting is called interlock.  Polymeric sand enhances interlock and stabilizes stonework. 

Until a few years ago, common sand was used to fill the joints that naturally occur in stone or brick pavers.  The sand would be swept into the joints and typically coated with a sealant that hardened the upper layer of sand.  This process worked reasonably well, but it was susceptible to being washed out by heavy rain, and also weeds and grass were often able to grow in the joints. 

Polymeric sand is a big step forward in joint filler for outdoor patio, driveway, and walkways.  Polymeric sand uses a water activated synthetic polymer to bind the sand particles and create a firm, water resistant joint filler.   Polymeric sand is applied like regular sand by sweeping or brushing it into the joints.  Once all the sand is brushed off of the stone and into the joints, water is misted over the stonework until it penetrates the sand.  The water activates the polymer, which hardens and binds the sand.

In addition to its excellent stabilizing properties, polymeric sand helps prevent water intrusion under your stonework which can lead to your stonework shifting or deforming.  Also, properly applied, polymeric sand prevents the growth of weeds and grass in the joints.  Finally, polymeric sand does not wash away so you do not have to continually replenish the joint sand for your stonework.
