Underground Structures
Below-ground basements for parking, storage, and more, including tunnels and metro stations
Typically comprising of below-ground basements used for car parking, mechanical rooms, services, storage, electrical rooms, commercial or other usage. They also include Cut & Cover Tunnels, UG Metro Station boxes or foundations.
Most commonly, a Type A barrier system using fully bonded membrane systems based on guidelines of IS 16471: 2017 is recommended, often with additional protection measures using a combination of Type B integral crystalline waterproofing admixture for structural protection and/or with Type C drainage systems.
Since these structures are buried and not easily accessible post construction, the waterproofing system for UG structures needs to be well thought, properly designed with optimal specifications.

Read MoreIntegral Crystalline admixture
- A special type of concrete admixture that enhances the waterproofing properties of concrete by reducing permeability in conformity to guidelines prescribed in ACI 212.3R-10.
- A powder added during concrete batching or in wet concrete, which is then mixed properly, forming crystals within the concrete which block pores by creating a waterproof barrier.
- Commonly used in basements, tunnels, and water treatment facilities, providing a permanent solution without additional materials by reducing permeability even under extreme hydrostatic pressure.
- Recommended to use integral crystalline admixtures for enhancing concrete durability which provides Type B protection as per IS16471:2017 in combination with Type A barrier systems.

Fully Bonded HDPE Composite Membranes
- A preformed and pre-applied HDPE fully bonded membrane which bonds to the wet concrete cast on the membrane. After the membrane bonds with the concrete, it forms an integral seal which prevents lateral water migration and ensures that it is unaffected by any substrate settlement.
- Reinforcement can be directly laid on top of the membrane and it does not require screed protection.
- Can be used for horizontal as well as vertical blindside applications.
