Strip foundations are suitable for light to medium loads and are often used in buildings with uniform soil conditions, preferably with large bearing capacity.
  1. Raft Foundations: Raft foundations, also called mat foundations, are designed to evenly spread the load of a structure over a large area, reducing the pressure on the soil. They are commonly used in areas with poor soil conditions. Raft foundations are characterized by a thick concrete slab that extends over the entire footprint of the building, like a raft, providing stability and support.
  1. Pad Foundations: Pad foundations, also known as spread footings, are used to support individual columns or posts. They are square or rectangular slabs of concrete that spread the load from the column over a larger area of soil. Pad foundations are commonly used in structures with isolated columns or in situations where strip or raft foundations are not feasible.

Deep Foundations

These foundations are structural elements that penetrate deeper into the ground to reach more stable soil or rock layers. They are used when shallow foundations are not feasible due to weak or unstable soil conditions, or when the building loads are exceptionally heavy. Their types include:

  1. Pile Foundations: Pile foundations are used when the soil at the construction site has low bearing capacity and is not strong enough to support the structure or when the load needs to be transferred to deeper, more stable layers of soil or rock. Pile foundations consist of long, slender columns/ cylinders created from concrete, called piles, that are driven deep into the ground. These piles can also be made of steel, or wood, depending on the specific requirements of the project.
  1. Caissons Foundations: Caissons, also known as drilled piers or drilled shafts, are deep foundation elements used to support structures like bridges, buildings, and other heavy structures. They are similar to pile foundations but offer a high level of load capacity. They are large, cylindrical, or box-like structures that are drilled or excavated into the ground and then filled with concrete or sometimes reinforced with steel.

Each type of foundation has its advantages and limitations, and the choice of foundation depends on various factors such as soil conditions, building design, and budget constraints.

TMT Bars in Residential Construction: The Unseen Essential for Durability

In the realm of residential construction, every detail matters. While we often pay close attention to the aesthetics and design of our homes, the structural materials that form the backbone of a building are equally vital. Of these, TMT (Thermo-Mechanically Treated) rods, play a silent but indispensable role in ensuring the strength and durability of residential structures.

The Basics of TMT Bars:

TMT bars, a type of reinforcing steel extensively employed in the construction sector, are recognized for their outstanding strength, exceptional flexibility, and resistance to corrosion. These qualities make them an ideal choice for various construction projects, with a particular emphasis on residential construction. These are the hidden heroes that strengthen concrete and enhance the structural integrity of residential buildings.

Enhanced Durability:

One of the biggest contributions of TMT in construction is their role in improving durability. They act as the skeleton of the concrete structure, providing tensile strength to withstand various loads, including wind, seismic activity, and environmental factors such as the total weight of the structure itself. They undergo a unique manufacturing process that involves controlled heating and rapid quenching, resulting in a tough outer layer and a softer inner core. This combination of strength and flexibility makes TMT bars more resistant to bending and breaking under stress, which helps to prevent structural failure and extends the lifespan of the building. The impactful Rib-on-Rib feature, exemplifying product innovation, is a hallmark of Shree TMT, reinforcing the bond between cement and steel and contributing to the resilience of such structures.

Improved Crack Resistance:

TMT bars greatly contribute to the crack resistance of concrete. During the curing process, concrete can develop micro-cracks, which can lead to more extensive damage over time. TMT bars help to contain these micro-cracks and maintain the structural integrity of the building. Their unique manufacturing process, which involves controlled cooling after hot rolling, ensures the bars have a fine-grained structure, which is essential for resisting cracks.

Enhanced Fire Resistance:

In the realm of construction, one crucial aspect gaining attention is the integration of fire-resistant features into TMT bars. These bars play a pivotal role in fortifying structures against fire hazards, offering enhanced safety standards. TMT bars, by virtue of their composition and construction, provide excellent fire resistance.
