The systematization and disclosure of information about the treatment techniques of rising damp, in the form of files / catalogue allows professionals, technicians and students instant access to the most relevant information on this matter.
The treatment techniques of rising damp usually used are based on four principles of intervention: Stop the access of water to the walls; Remove the excess of water in the walls; Stop the ascension of water in the walls and Concealing anomalies.
Stop the access of water to the walls - In order to stop the access of water to the walls, peripheral drainage may be a possibility.
Ventilating the Wall base - Creating ventilated peripheral channels, in addition to diminishing water contact with porous walls, increases the evaporation of absorbed water.
The files of the treatment techniques of rising damp are grouped according to their intervention principle: prevent access of water to the walls, remove the excess water in the walls, stop the ascension of water in the walls and concealing anomalies.

Therefore professional information provided to the public concerning their harmful impact not only on construction materials but also on human health, is very necessary.
The survey of the object revealed many places (practically in all open areas of the ground floor) with traces of intense ingress of water through peripheral constructions (mainly the ceiling), some places include biological stains (mildew) and deteriorated coating.
In both cases we can conclude that direct infiltration of rain water into the construction is the primary source of excess humidity.
Conclusion The primary reason for mildew occurrence on the indoor surfaces in the examined rooms is the infiltration of moisture caused by rain water during the reconstruction of the roof.
After stopping the ingress of water, apt handling of surfaces aimed at mildew removal and proper usage of the inner rooms with respect to temperature-humidity mode, further occurrence and spreading of mildew can be prevented.

The concentration of inhibitor was used of 15, 20, 25 and 30 g/ 350 mL of water.
Water-based drilling fluids were prepared with and without adding potassium citrate clay expanding inhibitor.
The low FV value obtained for this fluid is due to the addition of filtrate reducers used in its composition: starch (12 g/350 mL of water), CMC LV (3.5 g/350 mL of water) and calcite (25 g/350 mL of water).

Serious environmental pollution in recent years, the city's environmental assessment of the project for the construction of very strict, but for small towns from management and inadequate funding aspects, it is impossible to meet stringent environmental requirements, often directly harmful gases and wastewater discharge, causing serious air, water and soil pollution, to the production and living near the village of causing great harm.
Small towns in rural community planning and construction of the road has a long-term, complex, multi- faceted, determines the levels of local leaders and rural planning and construction professionals to be consistent, there is now "the next government, a plan" phenomenon, no form a perfect "government decision last evaluation mechanisms" and "the continuation and development of the new government coordination mechanisms" , especially in the areas of traditional agricultural production, local government and related planning and construction units do not have a clear understanding of the rural and urban settlements compared to the presence of relatively dispersed population live, basically there is no public transport, farming requires farmers farming issues reasonable radius.
Small towns in rural communities have a better urban environment system, you can get environmental benefits, agriculture, business, sustainable spatial development of urban facilities to avoid shortage of land and water resources, loss of resources and environmental pollution increase, eventually leading to the living environment deterioration in the quality of such phenomena.
Such as: critical infrastructure ( water, electricity, heating, transportation, waste disposal, health care, gas, etc.) supporting level, to enhance the absorptive capacity of the small town and the bearer capabilities of rural communities.

OVERVIEW Feng-shui (literally wind and water), Chinese geomancy, emerged gradually over thousands of years.
The Chinese characters for feng-shui, can be directly translated as "wind" and "water", To avoid wind and to have water is the basic premise in feng-shui site selection.
Yet most professional designers have little understanding of the methods of these traditional practitioners of the art.
The whole water network consisting of these streams also protects the city from flooding by releasing storm water.
Thus, water becomes the soul of the city.
