I am so glad I put my project on hold to find just the right product! GD Gravel is not only easy to install, it also saved me time, money, and a lot of back breaking work. This was a perfect solution for my needs as it allows water to flow freely through, keeping the patio surface clean and dry, and the pebble in place. GD Gravel truly is a no fuss, no muss, zero maintenance product. I have no doubt my patio surface will look just as great years from now as it did the day I installed it! Thank you for your top-notch customer service and superior product.
