After trying mulch and pea gravel between our flagstone that is on a slope, we were encouraged to try this product. We previously add issues with the mulch and gravel washing away in heavy rain. I was concerned the Insta-Path would hold up. It must have a cohesive component because it has held up to several storms. I only put it in half the flagstone path to test it out. We will for sure be doing the rest of the path in the spring.
The friendly staff suggested this medium for a area between our pool/basketball pad and the house. It stays put, was easy to add flagstone to, and forms a semi hard surface. I can sweep leaves off or move some rocks if I need to. Performs great!
