Materials for a weathering course include Materials for a weathering course include a base layer of brick jelly concrete (lime, surkhi, sand), a top layer of clay tiles, or alternatively, a lime terracing or a thermal insulation composite using materials like light-weight aggregates or Aerocon blocks.  The specific materials and their composition vary, with common components being cement, sand, water, and tiles, while innovative courses may also incorporate waterproofing chemicals like epoxy or polyurethane.  Common materials Base Layer (Brick Jelly Concrete): Lime : A traditional binder, often used with surkhi (brick powder) and sand.  Surkhi : Powdered brick, which acts as a filler and binder in the mortar.  Sand : Fine aggregate used to make the concrete mix.  Brick Jelly : A mix of brick pieces in a concrete or mortar.  Top Layer (Finishing and Protection): Clay Tiles: Specifically, flat or Madras tiles are often used and laid over the base ...

A weathering course is vital in buildings because it forms a protective barrier on exposed surfaces, preventing moisture penetration, enhancing structural integrity, and extending the building's lifespan by shielding against environmental elements like rain and sunlight.  It helps prevent costly damage from dampness, mold, cracks, and thermal issues, while also improving the slope for drainage and providing an aesthetic finish.     Benefits of a Weathering Course Prevents Water Seepage: The primary function is to stop water from entering the building, which helps prevent issues like dampness, mold, and damage to internal walls and ceilings.  Enhances Durability and Structural Integrity: By shielding structural components like roof slabs and parapet walls from direct exposure to rain, sunlight, and temperature changes, it reduces wear and tear and increases the building's lifespan.  Protects Waterproofing Layers : When placed above ...

What is a setback in buildings? A building setback is the minimum amount of open space surrounding a building that must be maintained. The government mandates a minimum setback distance for the construction of every building. It is necessary to keep a certain distance between the new construction site and any existing structures. Maintaining this distance prevents the structure from being close to highways, watercourses, or other structures. Types of setback in buildings Three kinds of building setbacks are considered when constructing a house, and these are: Road side margin : It refers to the space offered in front from the edge of the road side to the building. Side margin : It means the space offered on every other side of the building. Rear margin : Rear margin refers to the space offered from the rear or back edge of the building. What is the importance of a setback in buildings? Setback plays an integral role in any residential building due to the below reasons- To e...

  Types Of Kitchen Sink | Best Sinks for Kitchen Types Of Kitchen Sink The sink in your kitchen should be both functional and stylish. Kitchen sinks come in various types, sizes, shapes, and styles. They can be categorized based on their installation process, materials, and other factors. Some choices are practical, while others are just aesthetic. Different types of kitchen sinks have their own set of advantages, but the style you choose will be influenced by the size, installation, and use of the sink. Let’s look at the various types of kitchen sinks. Based On Installation Top Mount Sink Top mount kitchen sink, also known as a drop-in sink or self-rimming sink, is the most common type of sink. Here a sink is put into a hole in the countertop with little to no support underneath it. This sink is affordable and can be installed on most countertops. Top mount sinks usually come in durable stainless steel but are also available in porcelain or cast iron. Top-mount...

Aliyar reservoir located in Aliyar village near Pollachi town in  Coimbatore District, Tamil Nadu,  South India. The dam is located in the  foothills of Valparai, in the Anaimalai Hills of the Western Ghats . The  Aliyar Dam was constructed during 1959-1969 across the Aliyar river , mainly for irrigation purposes. Aliyar Dam was inaugurated on 2 October 1962 (Gandhi Jayanti day) by then Prime minister of India, Pandit Jawaharlal Nehru, K Kamaraj, the Chief Minister of Tamil Nadu. The project was commissioned in September 2002 to generate Hydro Electric Power. Aliyar lake receives water from Upper Aliyar Reservoir through the hydroelectric power station  in Navamali and the Parambikulam reservoir  through a contour canal. Aliyar dam, built as a  part of Parambikulam aliyar project (PAP) , retains a large reservoir. This project consists of a series of dams  interconnected by tunnels and canals for harnessing the waters of the Parambikul...

  Self-Compacting Concrete (SCC) – Advantages And Disadvantages Special types of concrete have been invented to be used for conditions that require specific considerations. Self-compacting concrete is one such type of concrete. Self-compacting concrete is new concrete that flows under its weight and does not require external vibration to compact. Self-Compacting Concrete It is utilized in construction where vibrators cannot be used for concrete consolidation. In this article, we will understand in detail about self-compacting concrete, the materials used to make it, its properties, advantages and disadvantages, and its applications in construction. What Is Self-Compacting Concrete? Self-compacting concrete (SCC), sometimes known as self-consolidating concrete, is one of the most popular forms of concrete. SCC has outstanding flow ability in its fresh state, performing self-compaction and material consolidation without segregation concerns. Self-compacting concrete i...

T otal stations are used for a variety of tasks, including  setting out points for construction, conducting detailed topographic surveys, measuring and monitoring existing infrastructure like bridges and buildings, and performing volume calculations .  They are essential tools for modern construction and surveying due to their ability to accurately measure horizontal and vertical angles, slope distances, and coordinates, which is crucial for establishing site control and ensuring project precision.    Key Applications in Civil Engineering Site Surveying and Topographic Mapping:   Total stations collect data to create detailed maps of project sites, helping to define contours, features, and elevations for design and planning.   Setting Out and Construction Layout:   They are used to lay out and stake out the exact locations of foundations, walls, roads, and other structural elements based on digital designs.   Monitoring Structural Health:   R...
