Concrete House Slab

Conventional Foundations

Let’s delve into the world of Conventional Foundations  conventional house slabs and footings. These foundational elements play a crucial role in supporting structures and ensuring their stability. Here’s an overview of each type:

1. Bored Piers (Pier and Beam Foundations)

  • Definition: Bored piers are holes drilled into the ground to support a building. They serve as individual foundation elements.
  • Construction Process:
    • A hole is bored into the soil using specialized equipment.
    • Reinforcement steel bars are inserted into the hole.
    • Concrete is poured into the hole.
  • Application:
    • Bored piers are commonly used in areas with reactive soils or where there is uncontrolled fill.
    • They are ideal for sloping sites or locations with challenging soil conditions.
    • Bored piers support suspended slabs or beams, allowing for flexibility in design.

2. Footings

  • Purpose: Footings distribute the load from the structure to the ground, preventing settlement and ensuring stability.
  • Types of Footings:
    • Strip Footings:
      • Long, continuous concrete footings that run around the perimeter of the building.
      • Used for load-bearing walls and Isolated beams for columns.
    • Stiffened Raft Footings:
      • A combination of strip footings and a reinforced concrete slab.
      • Suitable for Class A, S, M, M-D, H, and H-D sites.

3. Slab on Ground: Conventional House Slab

  • Description:
    • A flat, horizontal concrete slab directly placed on the ground.
    • Typically 100mm thick, thicker for special applications
  • Construction Process:
    • Site preparation and leveling.
    • Installation of a moisture barrier (polythene sheet) to prevent moisture rising from the ground.
    • Reinforcement mesh placed within the slab.
    • Concrete poured and leveled.
  • Application:
    • Commonly used for residential buildings.
    • Suitable for stable, non-reactive soils.
    • Provides a solid base for flooring materials such as tiles and carpets.

Remember that the choice between these foundation types depends on factors such as soil conditions, building design, and local regulations. Properly designed and constructed footings and slabs are essential for the longevity and safety of any structure. 🏠🔨
