Working from home has become the new normal, especially in…
The success of any construction project is decided long before the first brick is laid or the concrete is poured. One of the most critical phases in building strong structures is the pre-slab work stage. This phase lays a strong foundation for the entire construction project. Understanding the intricacies of pre-slab construction can help ensure stability, reduce long-term risks and prevent costly mistakes.
Pre-slab construction refers to the essential groundwork and inspections performed before pouring concrete for a structure’s foundation. This involves assessing the soil, ensuring proper formwork, reinforcing the slab and conducting quality checks. The entire goal is to confirm that the site is fully prepared to support the weight and function of the slab.
Essential utilities such as drainage, plumbing and electrical conduits must be placed before concrete pouring.
Construct temporary moulds (shuttering) to contain the wet concrete.
Ensure the formwork is sturdy enough to withstand the weight of the concrete.
Properly aligned formwork guarantees a uniform slab shape.
Use shuttering tape to seal joints and gaps in formwork. This prevents water leakage and helps maintain the integrity of the concrete structure.
This ensures uniform strength and reduces the risk of air pockets.
Vibrators are used to eliminate voids.
Smooth the top for a uniform texture.
Here are certain things to consider during pre-slab construction:
Before pouring concrete, shuttering and formwork must be properly installed. This supports the wet concrete and ensures a smooth finish.
Ensuring that reinforcement bars are correctly placed, spaced and secured is essential. These checks maintain the structural strength of the slab. Proper cover blocks should also be used to protect the steel from corrosion and maintain durability.
Waterproof membranes or coatings help protect against long-term damage due to water infiltration.
Routine site inspections, material quality checks and adherence to structural standards are essential to ensuring a defect-free slab.
