Also known as Below Grade Waterproofing, it is the most crucial part of waterproofing any structure. Due to the increase in land costs, it has become quite common to build a basement in buildings. These are used for diverse purposes. In independent residences, the basements are used for Entertainment, Sports and Health, Home Office, Storage, and sometimes for living also. In Commercial, Industrial, and Group Housing Buildings it could be used for Parking, Storage, etc. Even a small seepage can make it unusable.

Basement waterproofing materials are subject to water conditions that are typically more severe and intensive than the rest of the structure. The structure below ground level is often exposed to high hydrostatic pressure due to a higher groundwater table that may rise significantly high during the period of monsoons or due to the proximity of drains, rivers, canals, ponds, etc. The quality of groundwater can also damage the structural elements of basements. Due to this, it is important to intelligently design basement structures starting with adequate control of water conditions. Both groundwater and surface water should be channeled in a way that flows away from the structure.

The source of water that may damage the basement structure could be groundwater as well as surface water. It is important to select the right product and technology to protect basements from water damage. It is equally important to design proper drainage.

Basement Waterproofing can be done from the Positive or Negative side depending upon the site condition.

Terraces or Balconies are being used for different usage. Right from being a standard terrace, people also use these for the Terrace Garden, Kitchen Garden, Entertainment and activities area, etc. While the basic application stays the same, it may change according to end-use.

These are small but crucial areas for waterproofing as these will always have water usage. The Wet areas in a property are the Kitchen, Pantry, Washing Area, and Toilets.

Swimming pools are also water storage tanks. The waterproofing application in Swimming Pools, Water Bodies, and Water Storage is the same. However, there could be some changes depending on the site conditions.

External walls are among the most neglected areas for waterproofing. Most of the buildings are painted with decorative or textured paints. The walls are the outer skin of the building and due to the vagaries of climate, pollution and poor quality of building materials develop cracks. The dust and pollutants in the environment enter these cracks and expand when in contact with water. The cracks become wide and multiply due to this expansion. The decorative paints may not have good crack bridging capacity. The dry film thickness of most decorative paints is around 125 microns. Anti-carbonation coatings having a dry film thickness of 275-350 microns and elongation of 150% to 200% are the best suited for this application. These have more bonding and tensile strength and are available in different shades. Some of the coatings available have Thermal Insulation properties also.
