MSI – Beach Pebbles

One of the top options for your Massapequa Rocks is the MSI beach pebbles. These colored and polished pebbles offer a decorative look for your landscaping needs. You can use these pebbles to help protect the soil from extreme temperatures, keep weeds from growing, and add a beautiful look to your garden or flower beds.

These rocks can also be used in areas that are susceptible to washouts, such as under the downspouts. You can add the MSI beach pebbles to your front entrance for a more professional look, too.

We offer these pebbles in five different colors. Use them indoors and outdoors to add a decorative accent to your potted plants, as well.


Along with the beach pebbles, we also offer several types of gravel. Whether you’re looking for Bluestone screening, crushed bluestone gravel, red crushed gravel, white gravel, or pea gravel, we have the right choices for you. Our gravel comes in different sizes and can be delivered or picked up.

The right gravel can provide a beautiful walkway or driveway. It can also be used for several other areas of your landscape.


We also offer several other pebble options. Our Mexican Beach Pebbles are bagged and make a great choice for your landscape needs. If you prefer a white stone, we offer the Himalaya white pebbles from MSI, as well.

No matter the type of Massapequa rocks you need, we carry them. Our rock options work great for landscaping and for pathways throughout your property. At 9 Brothers Building Supply, we have the best rocks for your project.
