A sangan slab is most likely a misspelling of a sunken slab, also known as a sunk slab. Based on the provided information, a sunken slab is a type of concrete slab that is constructed at a level lower than the main floor level of a room or area.
Understanding Sunken Slabs
A sunken slab is intentionally positioned at a depth below the standard floor elevation. This depression in the slab creates a void or space beneath the finished floor level.
As referenced, "The sunken slab, also identified as a sunk slab, is a category of the slab that is set at a depth below regular floor level."
Purpose of Sunken Slabs
Sunken slabs are primarily used to conceal or accommodate various utility services that run within the floor structure. Instead of burying pipes and plumbing lines directly within the main slab, which can make repairs difficult, or having them exposed, they are routed through the space created by the sunken slab.
Common uses include:
- Plumbing Lines: Routing water supply and drainage pipes, especially in bathrooms and kitchens.
- Electrical Conduits: Running electrical wiring, though less common than plumbing.
- HVAC Ducts: Accommodating certain types of ductwork.
Applications in Construction
Sunken slabs are typically found in specific areas within a building where concentrated utilities are required.
Key application areas include:
- Bathrooms: To manage extensive plumbing for toilets, showers, bathtubs, and drains.
- Kitchens: For plumbing related to sinks, dishwashers, and water filters.
- Utility Rooms: Areas housing washing machines, dryers, and water heaters.
How it Works
After the sunken slab is cast at the lower level, the pipes, cables, or ducts are laid within the depressed area. Subsequently, this void is often filled with materials like brickbat coba, lightweight concrete, or other suitable fillers to provide a level surface for the final floor finish (like tiles or waterproofing) to be laid upon, bringing it up to the main floor level or slightly lower depending on the design.
This method provides easy access for maintenance and repairs compared to embedding services directly in the main structural slab.
