The Influence of Moisture on Facility Structure

Humidity increases in underground structures on surfaces not protected by a waterproofing and then migrates into the body of material. Excessive moisture has devastating consequences for all buildings, no matter at what temperature operation unprotected object. At low temperatures, moisture may expand in the pores, such as concrete a few years to completely destroy the bearing capacity. The positive temperature contributes to the intensive development of concrete corrosion.

The surfaces exposed to contact with water constantly, for example, walls, pools, foundations, basements, canals, reinforced concrete tanks, etc., need a strong durable coating capable of maintain their waterproofing properties for years to come.

How does water enter the structures?
If waterproofing system is broken, most of the water enters the roof or basement through cracks and seams. Also, when there is insufficient or defective insulation between the foundation wall and the capillary rise of groundwater intensely nourishes constructions moisture. It is known that the groundwater is rich in aggressive salts, acids, and others. The impact of chemicals in conjunction with osmotic pressure, capillary moisture can saturate the building construction to a height of 10 meters.

What happens to the concrete with excess humidity?

The result of the penetration of aggressive environment in the elements of construction is a reduction in the protective functions of concrete in relation to the fixture, which begins to corrode and collapse. The corrosion process of building materials reinforced with simultaneous exposure to physical factors, for example, if the material is in tension under the influence of tensile or compressive forces along with the aggressive or, for example, a liquid medium, the material is exposed to freezing temperatures and the cyclic freezing and thawing in liquid medium pores.

Permanent water subjection invariably leads to leaching of cement paste in concrete. As a consequence, the reduced strength of the building structure in the most critical nodes takes place. The harsh climate on the structure and material affects a large number of complex operational factors. To prevent the damaging effects the industry provides a variety of solutions with Polyshield on the list. A neoteric material is produced under a variety of brand names and manufacturers, including the leaders, such as Britannia. A far-famed roof coatings and roof waterproofing materials manufacturer even lists the material among its top-3 bestselling products.

Insulation of basements & waterproofing

A proper sealing of underground structures is a task that requires a serious professional approach. The premises are located in basements in dire need of waterproofing protection of the upper and lower part of the structure from moisture. High-quality waterproofing least demand in those cases when the ground water is not observed at the site of the construction of buildings. In order to protect underground structures necessary to apply water-repellent and resistant building materials, particularly when the level of groundwater above.

Although, concrete structures and waylaid water by themselves, they still are not completely waterproof. With purpose waterproofing materials which have a high “penetration” of the cement water resistant structures, as well as solutions can be significantly improved. Using these modern methods can be easily produced waterproofing works on already built structures. The main thing here is the correct application of waterproofing materials and hydrophobic water-repellent additives. For example, in the construction of swimming pools may be one dose, and in the construction of the foundation of the other.
