What:
- Substructure works refer to the underground construction components of a building or structure, including foundations, basements, and retaining walls. These elements form the base that supports the entire above-ground structure.
Why:
- Substructure works are essential because:
- They provide the necessary support for the above-ground structure, ensuring that it can bear the intended loads without settling or shifting.
- They are crucial in preventing water intrusion, which can cause damage to the structure and compromise its stability over time.
- They create usable underground spaces like basements, which can serve various purposes in both residential and commercial buildings.
- Proper substructure works ensure long-term durability and safety, making them vital for any construction project, whether commercial, residential, industrial, or infrastructural.
How:
- The process of substructure works involves several key steps:
- Excavation: The ground is carefully excavated to create space for the foundation and other underground structures.
- Foundation Construction: Foundation slabs and footings are constructed to distribute the weight of the building or structure evenly and to ensure stability.
- Waterproofing Installation: Waterproofing systems are installed to protect the substructure from water ingress, which is essential for maintaining the integrity of the foundations and basement areas.
- Retaining Walls and Basement Construction: Retaining walls are built to hold back soil and create usable space below ground level, while basement structures are constructed according to the design specifications.
