As these are lightweight but very strong, they are easy to lay and having a honeycomb structure, allow water to drain through them to ground. You can fill the cavities with soil, mulch or aggregate, or leave them empty. Kind regards Martin Leave a Reply Cancel reply Your e-mail address will not be published.
