How to keep sand between pavers from washing away
Pavers are an easy way to create beautiful outdoor living spaces, but you want to install them properly to keep your new patio looking great. Ensuring they stay in place without shifting starts with laying the proper substrate and ends with locking the pavers together by filling the joints. Sand is the crucial element for both tasks. While sand seems light and difficult to manage, it's effective in binding the pavers together and is the best way to keep pavers in place.
Create a strong base for pavers with a layer of porous material, such as gravel or crushed rock. This layer also helps improve drainage so your patio doesn't have standing water or water issues. The rock serves as the foundation for your sand layer.
Choose a sharp-edged sand that has varying grain sizes rather than sand with more rounded grains. Add a few inches of sand on top of the gravel and pack it down with a compacting machine. Compacting machines only compress a couple of inches of material at a time, so do this in two steps for a strong base.What Do You Pour Into Gaps Between Paver Bricks? : Designed Landscapes

The bedding layer also helps keep sand between pavers from washing away by providing support underneath the seams and pavers. Use the same type of sand as you did in the base. Filling gaps between pavers helps lock the individual bricks in place so they don't shift.
Once all the pavers are set in place, spread more sand over the top of them. Sweep the sand between the joints with a push broom. Repeat until you fill all of the paver gaps. Use the same type of irregular, sharp-grained sand as you did for the base and bedding layers. Irregular grain sizes with sharp edges bind together better and compact more neatly than smooth, homogenous sand particles.

Brick pavers can increase the curb appeal of any property. They can also provide some extra outdoor living space where you can spend time with friends and family on a nice summer day. To keep your pavers looking good and structurally sound some maintenance is required. One of the biggest results of weathering on pavers is the erosion of the joint sand.
This is the sand that acts like mortar in between the bricks. It is placed between all the pavers to help lock them in and keep weeds and moss from penetrating the surface between the pavers.
As wind and rain plague the surface this joint sand can wash out and compromise the pavers. Without joint sand, water can penetrate the surface and collect under the pavers. This creates a wet moist area between the pavers where weeds will begin to grow. In colder climates, freeze and thaw cycles can begin to heave and move the pavers out of place creating an uneven surface.
To protect joint sand from washing out between pavers it needs to be sealed. Once the pavers are cleaned and new joint sand is installed the entire surface can be sealed. This can enhance the beauty of the pavers and help to lock out moisture. The sealer will also solidify the joint sand so it will not wash away or erode as easily. The sealer helps to lock in the pavers and joint sand to create a weatherproof surface that will last for many years.
