Lesson 15:Specialised Gardens

Drainage and Waterproofing

• In every roof, the drainage aspect should be taken care of during the construction of the building.
• Drainage should not pose a problem unless it is disturbed during garden construction.
• Where the building is constructed with a view to make a garden on the roof, appropriate waterproofing material is used to make it impervious.
• Where this has not been done, precautions must be taken against seepage.
• A thick layer of asphalt may be spread after melting the material.
• Spreading of asphalted canvas or thick polythene sheet may also serve the purpose of waterproofing for a few seasons
