Pillar Build Granny Flats is a company specializing in the construction of granny flats in Sydney, Australia, and stands for the professionalism of our work. There are a number of specifications that focus on the core of your granny flat that we truly pride our company in, one of which is the Raft Slab. Therefore, anyone contemplating the construction of granny flats should have adequate knowledge of raft slabs and their advantages. Using our efficiency and adherence to the standard of work, we meet and provide the highest level of service that you expect from us.
What is a Raft Slab?
A large continuous concrete bed forms the base of a building; otherwise, people can refer to it as a mat foundation. This kind of foundation distributes the load of the building on a large area across the ground and is useful in areas with marshy or uneven soil. Syntonized with steel, raft slab guarantees the foundation level to give higher load bearing capacity and absorbs differential settlement. It currently presents an economical and effective means of creating foundations because of the increased instabilities of the ground.
Why Choose Raft Slabs?
1. Load Distribution
Raft slabs evenly spread the weight exerted by the building over the foundations. This is particularly crucial in areas where ground is relatively unsound or where it cannot bear any weight as it helps in uniform distribution on the surface hence the foundation of any construction project.
2. Reduced Excavation
As for structures of this kind, it is essential to know that raft slabs do not presuppose deep work in the ground. It significantly reduces the construction period and minimizes interference in the neighborhood.
3. Cost-Effective
Because of the shallow basis and reduced need for heavy digging and equipment, cable raft slabs can be cheaper than other existing types of foundation slabs. This makes them the best for use in granny flat developments.
The Raft Slab Construction Process
At Pillar Build Granny Flats, we follow a detailed process to ensure the highest quality of construction:
1. Site Assessment and Preparation
When planning and designing for the raft slab, we first make a soil test to understand the foundation first and the overall strategy for the construction. Finally, we clear and level the land, and if necessary, excavate the construction site.
2. Formwork and Reinforcement
Formwork shapes the slab, and we continuously cast reinforcement steel within the form. This reinforcement is important as it takes up the load of the building and as a result promotes long-term sustainability.
3. Pouring the Concrete
Fresh concrete of good quality is placed into the formwork and screeded level to the entire surface of the formwork. Thus, our team provides the necessary compaction of the concrete and its complete leveling to achieve an even surface.
4. Curing and Finishing
It gets hardened after the concrete is poured into the respective structures, after which it gets to cure for some time. This curing process is critical when one wants to attain the highest strength and serviceability of the concrete. After that, the slab is leveled as required and given a proper finish to serve as an appropriate foundation for the construction of the granny flat.
Stiffened Raft Slab: An Enhanced Foundation Solution
The extended raft slab is a refinement of the already described raft slab. It contains more reinforcement bars within the slab design so that it can have reasonable stiffness and support. This type of foundation is normally desirable when constructing on soils that are reactive or highly compressible.
Benefits of Stiffened Raft Slab
1. Increased Load-Bearing Capacity: Because of the extra beams, the design offers further support required for larger or multiple-story granny flat designs.
2. Improved Crack Resistance: The structures become rigid, thus reducing the crack formation to enhance the durability of the structures.
3. Enhanced Stability: Reduces the chances that will arise from differential movement basements on uneven or reactive soil types.
4. Versatility: Can be used in all types of soil and any construction specification.
Construction Process of Stiffened Raft Slab
Design and Planning: Evaluation and primary specification of the load-bearing structure to identify extra beams’ location.
Excavation and Site Preparation: Same to the traditional raft slab but with an addition of the beams that are part of the structure to be constructed.
Formwork and Reinforcement: Erecting formwork and processing steel reinforcement, including the proposed extra beams.
Concrete Pouring and Curing: Particularly in place, we are able to insist on exact concrete, as well as the time required for the initial hardening of concrete to achieve maximum tendencies to strength and solidity.
Benefits of Raft Slabs for Granny Flats
1. Enhanced Stability
Raft slabs provide great stability and offer granny flats the maximum support needed to keep the structure very stable and level on the ground. This stability is very crucial in zones where the terrain is likely to move or settle with more frequencies.
2. Raft Slabs for Crack Prevention
Thus, more preferable raft slabs are proposed as one of the construction solutions that can avoid crack formations in structures. This is done through the spreading of loads right from one corner of the building to the other in such a way that no point receives more stress than the other in order to eliminate the possibility of two parts of the building settling at two different rates. The casting of reinforcement steel bars within the concrete slab adds another level of reinforcement that helps to increase the overall slab’s strength and elasticity to cracks.
3. Energy Efficiency
The particularity of raft slabs is their continuity, which can contribute to the limitation of thermal bridges – all this can enhance the energy comfort of the house. This means that for the same price of heating or cooling, more areas of the granny flat will be effectively conditioned.
4. Versatility
Timber raft slabs make it possible to construct any kind of building and of different sizes and this makes them suitable for granny flats. No matter whether you are designing a simple studio that can fit into one single room or a complex structure with many rooms, a raft slab can come in handy to support the construction.
