A unique dome shaped structure of 36m diameter and 6 to 8111 height needed a complete water proof system giving complete protection against seepage of water . Further, the structure was required to have a green mow1d on top . This work required an impenneable cut off surface over the roof slab against water seepage, stabilisation of the sandy soil cover to avoid possible local shear failure and slump of sand fill and covering of the sandy overhead fill with micro rem forced green vegetation for erosion control. This paper discusses the design, construction and specification aspects.
