WATERPROOFING ON THE ROOFTOP FOR RENOVATION INTO A GARDEN TO PLANT PLANTS

1. Why do we need to waterproof the terrace before gardening?

Many families want to turn their rooftop into a green space to grow vegetables, flowers, and ornamental plants to both beautify the house and have a source of clean food. However, if not properly waterproofed, irrigation water and soil will easily seep down:

- Causes cracks in walls and leaks in the ceiling of the lower floor.

- Causes mold on walls, loss of aesthetics, and health effects.

- Reduces the life of the building, especially in the area of ​​roof floors, beams and columns.
