Waterproofing Membranes Waterproofing Membranes. A water-proof membrane is a thin layer of water tight material that is laid over the surface. Stagnated water is likely to seep into the structural slab overtime. In flat roofed terrace, the membrane is laid over a filler material that is sloped to ensure that water is drained away by … Read more
Polyurethane Waterproofing Treatment Polyurethane is made up of two components, base and reactor. Polyol acts as the base, while isocyanide is the reactor component. The combination of both these in a specific design ratio creates a liquid coating for waterproofing applications. Polyurethane is a rather popular choice due to its ease of installation. Unlike other … Read more
What is Waterproofing? Waterproofing in building construction is the process of making a structure water-resistant or impervious to the ingress of water. Waterproofing is essential as it prevents water from penetrating buildings and helps to keep the interior areas dry. It helps in reducing the humidity inside the building, minimizing the damage done to furniture … Read more
Sprayed Concrete for Repair of Structures Sprayed concrete can be defined as mortar or concrete pneumatically projected into place’. Sprayed concrete is used widely in the repair of deteriorated structures, because of its ease of application in situations where it is virtually impossible to use formwork to recast, and because it can be applied in … Read more
Underwater Construction Underwater construction is a method on how to place the concrete underwater. During the construction of bridges, dams or any structure where the foundation is most likely to lie underwater, the underwater construction is opted. Construction in water poses many difficulties especially in the places where the depth is considerable. During underwater construction, … Read more
Introduction to Artificial islands An artificial island is an island constructed by man rather than created by natural means. They are constructed by expanding the existing islets and by construction on existing reefs or merging some natural islets into a bigger island. Artificial islands are usually constructed by land reclamation. Land reclamation is a process … Read more
Weather Resistant Steel Weather resistant steel is a low alloy steel. Different from ordinary steel, weather resistant variant steel forms a protective oxide film called ‘patina’ in a appropriate environment. This oxide layer seals the surface and reduces corrosion loss. Weather resistant steel is also referred as weathering steel in market. This type of steel … Read more
Shear Connector A Shear connector is a steel projection provided on the top flange of steel composite bridge girders to provide necessary shear transfer between the steel girder and composite slab to enable composite action. The most widely used form of shear connector is the headed stud, or shear stud. Other forms of shear connector … Read more
What is Striking Formwork? The process of removal of formwork or shuttering in the process of casting concrete is known as striking. Once the concrete has achieved the initial recommended strength, to support the self-weight and any imposed loads, the shuttering is removed for further curing. Soffit forms are usually left in place for longer … Read more
