In most cases waterproofing pertains to underground application, however can also have an above-ground level, but below the roof location on a building. Dampproofing is usually installed on below grade walls and under floor slabs on grade.
Some of the categories and definitions of waterproofing and dampproofing are given below. Also we offer advice how to choose a contractor for this scope of work.
Waterproofing is defined as the resistive capacity of the passage of water under hydrostatic pressure force. Hydrostatic pressure force means water is appear from subterranean water accumulation. This pressure is higher in soi ls that prevent much water to flow away from a building, like clay and solid rock. Waterproofing Materials exist to outfit the diverse building site conditions:
Below Grade Walls – sometimes walls of a basement floor are protected against water leakage, seeing that the space may be used as storage, parking, or other employment permitted by standard code.
Above Grade, Buried Plaza Areas – for the most part, plaza waterproofing located above engaged spaces is hidden under pavers, grass-plot or other vegetation. As a general rule these applications are referred to as waterproofing projects, and may have different detailing methods and assembly configuration than a customary roofing assembly.
Above Grade, Surfaced Waterproofing Systems – there are many types of coverings intended for decking assemblies for pedestrian and auto traffic, sports surfaces and other applications.
Underground Buildings – the roofs of underground buildings are typically hidden under some amount of insulation, drainage systems and soil or other topping, and so considered waterproofing applications for that reason. Because of the unknown direction of water travel waterproofing materials, systems and details in essence are employed instead of typical roofing details. Once a structure is underground, water may leak from above or be set in motion by water pressure upwards the ground surface. To produce a successful waterproofing project there is a necessity of special flashings and other procedures.
Dampproofing
Dampproofing is defined as the resistance of water failing hydrostatic head pressure. Dampproofing materials commonly will not bridge fractures in concrete that may emerge during the building existence.
Dampproofing Applications
Dampproofing can be used either on commercial / industrial / institutional or residential applications. Mainly dampproofing products are spray applied very quickly and applied at around thinner in some cases than waterproofing. Dampproofing may be much less pricey than waterproofing as a result.
