Waterproofing A Master Design Solution for Concrete Durability

CIVIL ENGINEERING & CONSTRUCTION REVIEW (CE&CR) organized a webinar on the topic – “Waterproofing – A Master Design Solution for Concrete Durability” on the 20th of January 2022 (Friday) at 4:00 PM (IST) by Dr. S.K. Manjrekar, CMD of Sunanda Global.

The webinar had the following theme:

Twice as much concrete is used than all other building materials, including wood, steel, plastic, and aluminium. None have been able to replace concrete for performance and effectiveness.

Concrete is known to be robust, durable, and perfect for both utilitarian and decorative purposes worldwide. However, concrete is also porous, permeable, and prone to cracking so there are a need for concrete waterproofing.

Immense indications are present that concrete structures worldwide are not meeting their designed service life due to rapid deterioration – maximum caused by the exposure and movement of fluids and moisture through the concrete.

Much of the deterioration of concrete can only occur in the presence of water since aggressive agents penetrate concrete and react harmfully with the cement paste only when dissolved in water. Water is a carrier, and, in addition, it is required for chemical reactions to occur.

To alleviate the destruction associated with water permeability, the structure must be carefully evaluated to determine the appropriate waterproofing solution for the structure’s current and future needs.

Exposure of concrete to water slowly reduces the permanence/durability of concrete structures, thus raising the cost of maintenance of bridges, buildings, and other facilities.

Water’s toxic effects on concrete structures can be avoided through waterproof concrete technology, which efficiently improves the durability and lifespan of concrete structures, reducing long-term maintenance costs.

Having a reliable waterproofing system is vital for enhancing concrete durability! Appropriate specifications align with current technologies, and re­search will support a durable structure with less need for untimely repair or replacement work.
