    We’ve done lots of research through web for structural soil mixture that suits in middle east region specially in UAE and Oman but we rarely get one. We are aware that these system were widely used in US, Canada, UK and Australia and we want to bring this system here.Unfortunately this system is new to this part of the world and we do not have the availability of materials. Here we mostly get sandy soil whereas the specified soil (filler soil) should be a good quality type such as clay.


    I will be thankful if someone could share their knowledge?

    Is it for hard- or softscape?

    There are other ways (if not better) to acheive the same results without using structural soils. Even though they are sold in the US, they are not without controversy. It is an expensive way to go, especially if you do not have the required ‘ingredients’ that make the product. There are tree pits with a suspended tree grate, trenches with structural concrete caps, or subterrenean support products such as Deeproot Silva Cells (which advertise on this site) or their competitors. These work by providing an alternate means of supporting for whatever you want to put on them (some can act as drainage systems as well) without requiring the tree to be placed in any kind of compacted soil, which make for better root growth They also provide for an air space between the soil and the surface above that also benefits the tree. The sidewalk never touches the soil.


    What kind of trees did you anticipate planting in the structural soils?
