Protect Columns Settlement For Free

If the contact pressure at the base of the footing on the soil is uniform, and uniformly distributed, settlements may be tolerable if the type of structure and/or its exploitation can withstand such settlements.

In general, pile settlement should not be more than <2%D (where D is a diameter of the pile).

Differential Settlement Prevention Ideally, you should build a house on soil layers with minimal clay or silt. This way, you will not have to worry about the soil under your foundation shrinking and expanding. If possible, the house should sit on native soil and not fill soil.

Soil treatment methods include: Grouting. Soft soil consolidation with surcharge combined with vertical drains to accelerate compaction, Dynamic compaction, Replacement of soft soil with strong fill materials, Lime and cement columns, Electroosmosis, Freezing technique, Blasting,

Provision of deep basement. This method is useful in preventing excessive differential settlement between parts of a structure having different foundation loads. Deepest basement can be provided under heaviest part of structure.

Acceptable limits Similarly, American Society of Civil Engineers recommends that total settlement should not exceed 50 mm for residential buildings and 75 mm for industrial buildings, while differential settlement should not exceed 19 mm for residential buildings and 25 mm for industrial buildings.
