To be able to determine the type of foundation that “ideal” in the sense of cheap, easy and strong, need to be investigated soil (soil investigation). Meanwhile, you may also need to hire the trusted fix slab foundation near you whenever there’s a foundation damage that must be repaired quickly.
The results of this land investigation to find out:
The type and strength of the soil and its depth.
The depth of the groundwater level.
Estimate later settlement.
Estimates of the maximum allowable load and determines the type of foundation.
(Note: according to building permit rules, for multi-story buildings of three or more, land investigations should be carried out for recommendations of structural calculations thereon).
In planning the foundation there are 2 important things to keep in mind, namely; that the strength of the foundation is based on the strength of the foundation material itself and the underlying ground forces. The foundation material must have full strength and will not be damaged by the building load, it can be done the calculation analysis based on material permit stress.
The strength of the soil under the foundation must be able to support the foundation load and the building load above it in the absence of a decrease, it can be planned by making the size of the foundation so large based on the recommendation of the soil investigation, so that the soil permit voltage is not exceeded.
The things that can often cause damage to the foundation are:
The existence of changes in the function of the building, resulting in loading that exceeds the capacity of the foundation.
The occurrence of natural disasters, such as earthquakes, floods, landslides.
Damage to soil structure due to the construction of heavier buildings nearby.
The existence of uncertainty factors and soil types are not uniform, resulting in the occurrence of a wrong assessment in the planning.
