• Landscaping shapes can be done by using conventional soil or light weight screed / concrete, however engineers, architects facing few challenges while they choose conventional material for light weight filling
• First and foremost challenges is weight constraint, light weight fill should be very light in weight, it should not influence any stress or strain on the structure of the building.
•  Load Bearing Constraint: Light weight material should meet load specs of consultant and contractor
• Cost Constraint: Material must be cost effective in relation with conventional filling material available in the market
• Time Constraint: Work should be completed on fast track 
• Re-design Flexibility & Workability: Filling material should be easy enough to remove in case if any re-design comes in mind an over a period of usage
• It should be good insulation, resilient, having good acoustic properties
• To comply all environment issues such as recycling or re-usage & sustainability

Which material meets all the above challenges? All civil engineers, architects , contractor and consultant unilaterally agreed without any second opinion that STYRO expanded polystyrene EPS is one of the right choice to use in all landscaping and lightweight fill applications.
