We have just installed this product. We had a pea gravel pathway that was very squishy and irritating to walk on. We decided to try this on a gamble. We pulled back the gravel to the existing weed mat, laid this product, then raked the gravel on top. It is awesome! Very solid and very easy to walk on!!! Of course we haven’t gone through a winter or many years of having this product so I’m not certain how it will wear, but I’m very very pleased with the outcome.
