The concept of waterproofing or protecting buildings against the damaging action of water derives from the need to avoid water and humidity related elements that act negatively upon constructions. This negative effect can present itself in several ways, creating health problems, structure deterioration, facility damage and others. Not to mention, that repairing a building damaged by water can be very expensive!
Permeability most frequent causes are: porous or flawed material, badly sealed splices, crack existence, building defects and inadequate surface pendant. A typical problem in most Water Retaining Structures is the leakage of water through Construction and Cold Joints. A construction joint is formed when concrete is cast in different stages successively. These joints may be horizontal, vertical, inclined or curved depending on how the concrete is cast.
However, we can find different kinds of humidity: the one that gets in from the outside (because of rain, different kind of water infiltrations, ground humidity or underground water), building's own humidity (permanent or because of the construction) and the one produced gradually by the building (because of its service as well as due to condensation and water leaks).
Basic conditions for waterproofing involve the surface's fitness for treatment and its cleanness. Building waterproofing can be done in a surface with/without the presence of water and with/without previous treatment.

Surface waterproofing: done with coating plates, bituminous emulsions, vinyl pastes, resins and sealants
Integral waterproofing: integrated to the mass of concrete, affecting its permeability.
Hydrophanous waterproofing: integrated to the mixing water or used as curing systems, allow the improvement of concrete's characteristics such as workability, compression resistance, decrease of reinforcement steel corrosion, decrease of fissures and cracks, and extended durability.

Rigid waterproofing is meant to seal filtrations, make waterproof concrete structures or waterproof coatings. Treatments for rigid waterproofing generally are: concrete and cement integral additives, and cement, epoxic, plastic, or metallic coatings.
Flexible Waterproofing is intended for structures affected by temperature changes and water settlements. This kind of waterproofing is a protection capable of absorbing movements without suffering damages that could allow water access. Flexible treatments are membranes, hot asphalts, cold asphalts (based in water or solvent), polymer emulsions, vinyl emulsions, and acrylic emulsions.
To fit your particular needs, you will probably need to use one or a combination of the above kinds and systems of building waterproofing. The best way to go is to ask an expert in your area to help you find the best solution for your building.
Something is for sure, if you take good care of waterproofing your building you will keep your structure and investment safe from water!
