Terrace Garden Plan with Lawn Plantation and Drainage Detail

This terrace garden plan drawing presents a detailed sectional layout showing lawn plantation arrangement over the existing slab with complete waterproofing and drainage specification. The drawing clearly illustrates soil layer placement above a geotextile membrane and a 25 mm thick drainage cell for proper water flow management. A 50 to 100 mm thick PCC layer is provided in slope 1 to 75 towards the drainage pipe to ensure efficient runoff control. Waterproofing treatment using 3 mm plastomeric bitumen compound is indicated below the drainage system, along witha slurry mix layer over the slab for structural protection. Parapet wall and coping detail are also clearly marked in the terrace garden plan.
