Can we store top soil in layers of more than 40 cm thickness as we have a space constraint on our site?
As per GRIHA requirement top soil should not to be stacked more than 40cm in height.
It is not necessary for the project to store the entire topsoil extracted from the project site, instead you may store only the quantity that will be required for future landscaping in the project. Further, if you are still running short on storage space, you may store the topsoil at some other location (empty plot) or nursery and bring it back for reapplication during landscaping work. Please note that the points will be awarded only if it is re-applied on site and dated photographs will be required to demonstrate compliance.
