Waterproofing of Structures:Challenges and Solutions
It rained and people sought protection against rain water falling on the head, Figure 1. The concept, the art and the science of waterproofing developed from this desire for protection against rain water. In the beginning, most people thought that the objective of waterproofing was to prevent rain water from falling on their head. As people started using delicate
Knowledge and Technology Management for Waterproofing Using Construction Chemicals
What we build brick-by-brick, may get destroyed by drop-by-drop seepage of water. To avoid premature deterioration of the buildings and other concrete infrastructure facilities, a scientific approach towards waterproofing is essential to avoid leakages and seepages. This calls for knowledge and technology management for designing efficient waterproofing
Concrete Tunnel | Concrete Structures | Metro Railway tunnels
Conventional concrete, which can be considered to be an artificial rock, is not intrinsically waterproof. It absorbs water. The rate of absorption depends upon many factors, including the porosity of concrete
Strengthening of RC Beams in Shear Using Composites Fabrics An Experimental Study
Studies on the use of composites materials for the strengthening of shear deficient concrete structures are limited. The research in this area started since 1991. This is because various configurations of composite sheets can be used
Sealants In Concrete Pavements, Roads, Highways & Building Construction
A sealant is a viscous material that changes state to become rubber like compound, once applied, and is used to prevent the penetration of air, gas, noise, dust or liquid from one location through a barrier into another. Typically
