What kind of sand between pavers

A loose-fill sand will wash away over time or when it is exposed to heavy rains. Because of this, polymeric sand for paver joints was developed to hold its form and to keep everything in place.

In recent years, a newer type of sand for paver joints has been developed which softens upon becoming wet. Polymeric sand is simply a granular sand material that is placed within the cracks and joints between stone pavers as a means of interlocking the units and preserving the beauty and integrity of the pavers. A water-activated polymer is introduced to the sand. After applying the material to the paved surface, the sand is sprayed down with water which causes the polymers to harden.

This then secures the sand in place. Polymeric sand is so durable that it can actually be power washed, with care. In addition to preventing the need for you to replace your joint filler after a rainstorm, the durability of polymeric sand ensures that water will be unable to seep beneath the paving stones.

This significantly reduces the chance of your pavers migrating, and stops water from washing away the base layer of sand which could cause the paving stones to sink.

Polymeric sand will keep your pavers looking great for years to come. This is because the edges grind together and locks the layer of sand in place, thus eliminating any chances of movement or shifting. Usually, contractors use concrete sand because of its granular texture, but mason sand works just fine too.

When exposed to heavy rains, granular sand will wash away over time. For this reason, polymeric sand is used because it retains its form and keeps everything stable. Another sand type used for joint filling is kiln dry sand.

Kiln dry sand is very fine and contains no moisture, making it perfect for filling in the joints between paving slabs.

It keeps the structure of the paving rigid and strong by stopping water ingress and prevent moving or shifting. Polymeric sand is a combination of fine sands added with polymer, hence the name.

There are two different types of sand used when building paver patios. The first is called by many names: all-purpose, leveling, or paver sand. These are all the same sand and are spread over the leveled ground on top of the landscape fabric, but beneath the PaverBase and pavers. This sand can also be used as the second type of sand, joint sand, which fills the gaps between the paving stones if they have spacer bars or gaps.

Flat-sided paving stones do not need joint sand.
