For a project to be successful, it relies heavily on the decisions and actions you take early in the planning phase. One such crucial step in the construction process is the pre-slab work stage. This stage lays the foundation for the complete project. To ensure a successful pre-slab work stage, you need to follow a comprehensive checklist.
This checklist addresses all the crucial aspects. Let us consider various aspects of the pre-slab construction checklist:
Formwork and centring
The formwork and centring work like moulds for the fluid concrete. To make the concrete, you need to mix cement, water, and aggregates in a specific proportion according to the site’s requirements. Today, you can choose from different cement, depending on the construction job. These include Ordinary Portland Cement, Portland Pozzolana Cement, Portland Slag Cement, Composite Cement, etc.
The formwork or shuttering supports vertical structures, including columns, walls, etc. Meanwhile, centring, which is also a formwork, supports horizontal structures such as floor beams and slabs. During construction of the formwork and centring, ensure the following:
- Maintain accurate alignment of the formwork to ensure the desired dimensions and shape of the slab.
- Ensure they provide enough support to the concrete during the curing and pouring phases.
- The formwork should withstand the concrete’s weight without deflecting.
- Finish the formwork properly to ensure a smooth surface for the slab.
- Once the concrete can hold its weight without losing shape, you can remove the formwork.
- Ensure the formwork is waterproof so that it does not absorb any water from the concrete.
Reinforcements
In projects involving the construction of bridges, high-rise buildings, and more, using reinforcements like cables, rods, and steel bars could boost the strength of the concrete.
Including insulation and vapour barriers
Vapour barriers remove air flows and keep the structures protected from unwanted moisture. You should install insulation materials to boost the thermal comfort of the structure.
Pre-addressing moisture
Moisture can seep into cracks and cause water damage to the walls. However, by taking appropriate measures during planning, you can protect both the outside and inside of your home. Specific measures that you can take include:
- Perform moisture testing on the subgrade. This ensures that it meets the required moisture content before you pour the concrete.
- Applying appropriate waterproof coatings or membranes can also keep the slab protected from water damage.
Quality control
It is crucial to implement quality control protocols. These include the following:
- Conduct relevant tests to ensure the quality of the materials used.
- Perform regular inspections during the pre-slab work stage.
Safety considerations
You need to ensure equipment safety and protect workers from falls during construction.
Conclusion
Now that you know the pre-slab construction tips, you can use them to address the various crucial aspects and ensure a successful pre-slab work stage.
