01. Foundation Treatments for Soil:
● Flatten and compact the ground, ensuring that the compaction ratio of the base layer is 93% or greater, the slope is 0.5% or less and that drainage is functional after construction is complete.
● Gravel layer: Lay a gravel layer of 10-15 cm and cover it with a permeable geotextile to prevent the sand from coming out and flatten it as well.
