Shallow foundation:
A type of foundation that is used when the earth directly beneath a structure has sufficient bearing capacity to sustain the loads from the structure
Deep foundation:
A type of foundation that is used when the soil near the ground surface is weak.
1. Light, flexible structure: older residential construction, residential construction which include a basement, and in many commercial structures,
2. Nice soil condition: hard, uniform soil.
3. Cheaper than deep foundation
4. Easier construction
5. Typically types: spreading footing foundation, slab-on-grade foundation, pad foundation, strip foundation, and raft foundation.
Spreading footing foundation: controlled by several factors: lateral and vertical capacity, penetration through near surface layers likely to change volume due to frost heave or shrink-swell.
Mat-slab foundation: the distribution of loads in a mat slab helps reduce differential settlement due to the non-uniform building loads
1. Heavy, rigid structure: other uncommon building, such as large bridge, tower, and the Empire State Building.
2. Poor soil condition: liquefaction, soft clay and sands.
3. Typically more expansive
4. More complex to construct and more time than shallow foundation.
5. Typically types: battered piles, bearing piles, caissons, and friction piles.
Friction piles: Friction piles obtain a greater part of their carrying capacity by skin friction or adhesion. This tends to occur when piles do not reach an impenetrable stratum but are driven for some distance into a penetrable soil. Their carrying capacity is derived partly from end bearing and partly from skin friction between the embedded surface of the soil and the surrounding soil.
End bearing piles: End bearing piles are those which terminate in hard, relatively impenetrable material such as rock or very dense sand and gravel. They derive most of their carrying capacity from the resistance of the stratum at the toe of the pile.

What kind of building rests on a foundation?
Foundation is the underground or the substructure part of a building that transmits the load of the super structure to the ground safely. it is the lower part of building on which the whole structure rests. it may be made up of stone masonary, PCC or RCC. depending the width to depth ratio it may be a shallow foundation or a deep foundation. shallow foundations are used for smaller structures and shallow foundations are used for multistoried buildings where the load carried by soil is more.
What is a deep strip foundation and when is it used?

Why you have to use raft foundation?
A raft foundation, also known as a mat foundation, is a type of shallow foundation that is used in construction to distribute the weight of a building or structure evenly across a large area of soil. It is typically used when the soil's load-bearing capacity is relatively low, or when the building's loads are heavy and spread over a wide footprint. Here are some reasons why a raft foundation might be used: **Uniform Load Distribution**: Raft foundations are designed to distribute the load of a building uniformly over a larger area of soil. This helps prevent localized settlement that could occur with point loads or strip foundations. **Poor Soil Conditions**: If the soil at a construction site has low bearing capacity, meaning it can't support heavy loads without excessive settlement or deformation, a raft foundation can help distribute the loads over a larger area, reducing the pressure on the soil. **Variability in Soil**: In some cases, the soil properties might vary across the construction site. A raft foundation can help mitigate the effects of differential settlement, where one part of the building's foundation settles more than another due to varying soil conditions. **Heavily Loaded Structures**: Raft foundations are commonly used for buildings with heavy loads, such as multistory buildings, warehouses, or industrial facilities. The broad contact area with the soil helps prevent excessive stress on the ground. **Reduced Foundation Depth**: Raft foundations are shallow foundations, meaning they are located closer to the ground surface compared to deep foundations like piles or caissons. This can save excavation costs and make construction more efficient. **Economical Solution**: In some cases, a raft foundation might be more cost-effective compared to using deep foundations, especially when the structure's loads are spread out over a large area. **Stability in Poor Soil**: If the soil has a potential for lateral movement (such as in areas with high groundwater or seismic activity), a raft foundation can provide stability by distributing lateral forces over a larger area. **Preventing Differential Settlement**: In situations where multiple structures are built close to each other, a raft foundation can help prevent differential settlement that might occur if different structures have different foundation systems. It's important to note that while raft foundations offer several advantages, they might not be suitable for all construction scenarios. Factors such as soil type, building loads, local climate, groundwater levels, and structural design will all influence whether a raft foundation is the appropriate choice. Engineering professionals, including structural and geotechnical engineers, play a crucial role in determining the most suitable foundation type for a specific project based on site conditions and building requirements.
What can be the cause and cure of water seeping up through the wooden joints of a new concrete driveway and this is not occurring at any other driveway in our community?
If you have laid a foundation fairly deep and haven't 'dialed b4 you dig" you might have hit a pipe, if not try removing the joins and finding the source of the problem once the concrete has dried

Differentiate between shallow and deep foundation?
The difference between a shallow and deep foundation is very simple. A shallow foundation is not very deep and a deep foundation is.
Comparison between shallow foundation and deep foundation?
A shallow foundation is generally considered any foundation element that is 6 feet or less in depth. or the depth of foundation is equals to its width of the foundation. Examples are thickened edge slabs and grade beams that are supporting minimal weight.
What is the difference between deep water and shallow water?
Its better to swim in the deep water but if you have a child its safe to swim in the shallow water.
How many types of foundation?
types of foundation....1. shallow foundation 2. deep foundation 3. pile foundation
What is the difference between shallow well and deep well?
The common misconception is that the difference between a shallow well and a deep well is the depth to which you dig to hit water. While this may be true in some cases, this isn't the basis of classification. A shallow well is one where the primary source of water is an unconfined aquifer and a deep well is one which is fueled by a confined aquifer.
What is the shallow foundation?
That is a foundation that is mot very deep. -If you need more comprehensive info then tell us more.
What are shallow deep paintings?
It is called a shallow or a deep painting. Shallow means it has light colors. Deep means it has contrast between light and dark such as shadowing.
What is the difference between a deep borehole and a shallow borehole?
A deep borehole is drilled much deeper into the ground compared to a shallow borehole. Deep boreholes are typically used for extracting resources such as water, oil, or gas from deep underground reservoirs, while shallow boreholes are often used for environmental monitoring, water wells, or geotechnical purposes at shallower depths.
What is the difference between shallow marine environment and deep marine environment?
deep marine animals have short narrow body to overcome water pressure, having no eyes or reduced eyes, low physical and metabolic activities. shallow marine animals have reverse properties to that.
