Using Foundation Space
When it comes to construction, the use of foundation space is a critical aspect to ensure the structural integrity and functionality of any building. However, not all homes are built with deep foundation spaces. Shallow foundations are common in certain regions and under specific circumstances, largely influenced by soil type, climate, and design intent.
These foundations are typically used when the load of the structure is light or the soil near the surface is capable of supporting that load. Shallow foundations are generally more economical and less labour-intensive, making them a popular choice for smaller buildings, such as residential homes.
Projects on tight budgets
One of the reasons shallow foundations are often utilised is their cost-effectiveness. Excavating deeply into the ground can be expensive, particularly in areas where labour and machinery costs are high. Shallow foundations require less excavation and fewer materials, making them efficient for projects on tight budgets.
They are especially suitable for areas with hard, compact soil near the surface, where deep digging is unnecessary. However, while cost and practicality drive the choice of shallow foundations, it is crucial to employ the right techniques and raw materials to ensure durability and stability.
Prevent chemical reactions
When constructing shallow foundations, a combination of techniques and high-quality raw materials is essential. A common technique used is spreading a layer of compacted gravel or crushed stone before laying the foundational slab.
This layer serves as a stabilising cushion, promoting drainage and preventing waterlogging that could damage the structure. One of the key raw materials in this process is silica sand, a finely textured material that enhances the strength and stability of concrete mixes used in the foundation. Silica sand is highly valued for its durability and composition, which prevent chemical reactions that could weaken the foundation over time.
An eco-friendly option
Another crucial component in shallow foundation construction is dried aggregates. Dried aggregates, such as crushed stone, gravel, or recycled glass media, act as fillers in the concrete mixture. These materials are vital for distributing the load evenly and improving the overall tensile strength of the foundation.
Recycled glass media, in particular, is gaining popularity as an eco-friendly option. Made from processed glass waste, recycled glass media not only reduces the environmental footprint of construction but also offers exceptional durability. Its angular particles enhance bonding within the concrete mix, making it an excellent choice for modern building projects.
Provide a uniformly flat surface
Silica sand makes a second appearance in finishing touches for shallow foundations. Beyond its use in the core concrete mix, silica sand is often employed in surface treatments or as a levelling material before flooring installation.
Its fine granules provide a uniformly flat surface, which is critical for laying tiles, hardwood, or other floor coverings. By ensuring a smooth and even foundation, silica sand helps maintain the aesthetic and structural appeal of the home.
Layers of compacted gravel
The construction process for shallow foundations frequently involves stabilising the surrounding soil. Techniques such as soil compaction and the use of geotextile materials ensure that the ground around the foundation remains firm and resistant to erosion.
Dried aggregates, once again, play a role in this process, with layers of compacted gravel or crushed stone often employed in and around the foundation perimeter. These strategies help safeguard the foundation from shifting or settling over time.
Create stable and long-lasting structures
While shallow foundations may lack the depth and complexity of their deep counterparts, their practicality and efficiency have secured them a prominent place in modern construction. Proper techniques and the judicious use of materials like silica sand, recycled glass media, and dried aggregates ensure that these foundations can support homes effectively and sustainably.
By utilising these methods, construction professionals can create stable and long-lasting structures, even when working with limited resources or challenging site conditions.
