This document discusses basement moisture issues and solutions. It covers five major causes of basement moisture: concrete cracks, hydrostatic pressure, capillary action, vapor transmission, and condensation. Traditional waterproofing methods are being replaced by new materials like dimple sheet and geocomposite drainage products. These advanced products can redirect groundwater, act as a capillary break and vapor retarder, and create airflow to reduce condensation on foundation walls. The document focuses on how these new materials protect against water damage from hydrostatic pressure in particular.

Hydration-Induced Stresses in Concrete Buttressing of Existing Concrete Gravi...Nihal Vitharana
The raising and/or stabilising of existing concrete gravity dams by continuous concrete buttressing is a viable solution and, in some cases, it is the only solution available. There are few medium-large dams in Australia currently under consideration for raising with continuous buttressing.
Two of the major issues to be surmounted are: (a) the existing dam should not be subjected to cracking (particularly on the upstream face) due to heat-hydration effects, and (b) the requirement for the two dam bodies to resist the hydrostatic and other loadings as a monolith (unified dam).
However, there is great need for understanding the mechanisms involved in selecting an appropriate heat-of-hydration model and in calculating thermal stresses rationally. Due to such lack of understanding, expensive precautions, mostly with compounding conservatisms, would be adopted in concept and detailed designs eg. shear-keys on the interface, artificial cooling, post-grouted interface, anchor bars at the interface, concrete with high cement contents. On the other hand, unsafe designs could be the result.
The paper discusses these issues highlighting that a rational approach can be adopted to economise the design and construction processes. An example is also presented to demonstrate how the potential for temperature-induced cracking in new and old dam bodies can be evaluated with reduced uncertainty by considering all the mechanisms involved in a holistic way.

Water-Resistant Solutions and Tile Proficiency: An Exhaustive Manualalexander68416511
Within the domain of construction and the upkeep of structures, the domains of water-resistant solutions and tile proficiency assume paramount importance in ensuring the enduringness and structural soundness of edifices. Ranging from private residences to commercial edifices, the imperative of effectual water-resistant measures and precise tile methodologies cannot be overstressed.
Waterproofing Challenges and Suggested Remedial measures for High Rise Buildi...IJSRD
Leakage can occur in both old and new constructions. Mostly it has been witnessed in old constructions. This indeed is a major problem faced by the buildings. As it is affecting both exterior and interior look of buildings and also causing damage to structural members. It also harms paint of the wall. The problem includes survey of not only leakage, but also dampness and seepage in the residential blocks. This study provide a better and more scientifically based understanding of the role of waterproofing materials to assist the prevention of moisture from penetrating sub-grade walls and slabs. The significance of the research topic is to provide a review of the development of waterproofing materials in implementing waterproofing system in building industry with some case study reference in the current market in India.
The presentation is an exposition on Mitigation Strategies For Flood Proofing. It talks about damages due to flooding, flood proof materials, active & passive flood proofing, flood barriers & all.

Damp is generally defined as unwanted water or moisture.
Dampness is the access and penetration of moisture content into building through its wall, floor, roof etc.
The existence of dampness in buildings is one of the most damaging failures that can occur in buildings.
Every building should be damp proof.
The main idea of damp-proofing is to protect buildings against the damaging action of water and humidity that act negatively upon constructions.
Neither humans nor buildings can tolerate too little or too much of water.
Excess water in buildings is called Dampness. The root of all evil is water.
In construction, a building or structure is waterproofed with the use of membranes and coatings.
Oil-based waterproofing is generally used for roof leakage after construction and uses only on the wall like a primer.
Moisture can also affect the health of occupants typically through the potential for breeding harmful organisms.
On the other hand, moisture reduces the shrinking cracks of wood and furniture, and up to a point, is necessary to avoid respiratory discomfort.
Thus, moisture is both a necessary constituency of our built environment and a potential liability.
The issue, then, is not to eliminate moisture from our buildings, but to control it and its movements.

2. Moisture Problems – Major Causes of Below Grade Moisture EntryMoisture Problems – Major Causes of Below Grade Moisture Entry
Concrete cracks - Cracks in a foundation walls of concrete or masonry compromises the
structures ability to provide a barrier to water/moisture entry. Causes of cracks are settlement,
expansive soils, frost, shrinkage due to natural process of concrete curing.
Hydrostatic Pressure – Ground water pressure build up that exerts lateral and vertical
pressures on the foundation structure
Capillary Action – The movement of liquid moisture through a structure or substrate
(concrete) using voids and fissures in the material acting as a path for water travel
Vapor Transmission – The movement of air borne moisture through a structure or substrate
due to vapor pressure equalization (high concentration to low concentration)
Condensation – The formation of liquid moisture on or within a structure or substrate due to
the airborne moisture concentration and temperature conditions being ideal for water to form
