👉Foundation Types

⭐️Shallow Foundations

🚧Shallow foundations transfer building loads to the soil at relatively small depths (usually less than 3 meters). They are economical and suitable when strong soil is available near the surface.

🔰Types:

- Isolated Footing
- Supports a single column.
- Used when loads are light and soil is strong.
- Simple and cost-effective.

- Combined Footing
- Supports two or more columns.
- Used when columns are close together or when soil bearing capacity is low.
- Ensures even load distribution.

- Strip Footing
- Continuous footing under a wall.
- Common in load-bearing wall construction.
- Transfers loads along the length of the wall.

- Raft (Mat) Foundation
- Large slab covering the entire building footprint.
- Used when soil has low bearing capacity or when loads are heavy.
- Distributes loads uniformly, reducing differential settlement.

⭐️Deep Foundations

🏷Deep foundations transfer loads to deeper, stronger soil or rock layers.
⏺They are used when surface soils are weak or compressible.

⚡️Types:

🎲Pile Foundation
⏺Long, slender columns driven or cast into the ground.
Load transfer mechanisms:
Skin Friction: resistance along the pile shaft.
- End Bearing: resistance at the pile tip resting on firm strata.
- Suitable for bridges, high-rise buildings, and coastal structures.

- Pier Foundation (Caisson)
- Large diameter shafts drilled into the ground and filled with concrete.
- Used for heavy structures like dams, towers, and piers.
- Provides stability by reaching competent bearing strata.
- Constructed by drilling/casting methods.

👉Types of Foundations Used in Buildings

💫Foundations are the structural elements that transfer building loads safely to the supporting soil.

🌟The selection of foundation depends mainly on soil bearing capacity, structural loads, groundwater conditions, column spacing, settlement requirements, and site constraints.

☄A. Shallow Foundations

Generally used when suitable bearing soil is available at a relatively shallow depth.

1. Isolated (Pad) Footing

Supports a single column.

Suitable where soil has adequate bearing capacity.

Common for individual RCC columns.

☄2. Strip (Wall) Footing

A continuous footing provided below a load-bearing wall.

Suitable for uniform soil and moderate wall loads.

Distributes the wall load over a wider soil area.

☄3. Combined Footing

Supports two or more columns on one footing.

Useful when columns are close together or a column is near a property boundary.

Can help reduce eccentric loading.

☄4. Raft (Mat) Foundation

A large reinforced-concrete slab supporting several or all columns/walls.

Useful where soil has low bearing capacity or columns are closely spaced.

Can reduce differential settlement when properly designed.

B. Deep Foundations

Used when adequate bearing strata are not available near the ground surface or when loads/ground conditions require deeper support.

🚧1. Pile Foundation

Consists of piles extending into deeper soil or rock.

Transfers structural loads through end bearing, skin friction, or both.

Suitable for weak surface soils and heavy loads.

🚧2. Well/Caisson Foundation

A large hollow foundation sunk into the ground.

Commonly used for heavy structures and foundations subjected to scour or water-related conditions, particularly bridge works.

🚥Important Note

The foundation type should not be selected from soil type alone.

A geotechnical investigation and structural design are normally required to determine the appropriate foundation size, depth, reinforcement, allowable bearing pressure, and settlement criteria.

Local building codes and site conditions must also be considered.
