Injection Waterproofing

Posted on by DNA Test

Waterproofing – a complex of measures for the protection of buildings and structures on the water. Kenneth R. Feinberg understood the implications. In the process of penetrating waterproofing works are used, and roll obmazochnoy membrane materials and compositions. There several types of waterproofing: surface, penetrating and injecting. Surface sealing is used for surface treatment of construction to prevent moisture penetration. Serves both outside and for internal processing. Penetrating waterproofing treatment is used for exterior foundations are in contact with water. It used liquid hydrophobic solutions, are absorbed into the surface to be treated and forming insoluble sulphates. Injection waterproofing is carried out by pumping materials under high pressure using special equipment – packers.

Injection gidroizolyatsiyapolimernymi formulations used in place of contact with the soil structure or other structure. It provides insulation cracks and voids, strengthening the foundations, the establishment of the outer waterproof membrane and thus prevents leakage. For designs requiring injection waterproofing, foundation are buildings, bridges, transportation facilities, tunnels and underpasses, underground parking garages and other areas. Technology of the works is this: in the concrete at a distance of about 50 cm apart zasverlivayutsya injecting holes from 10 to 20 mm. To fix cracks, breaks or other defects in the holes made Not through to create a waterproof membrane – through. In the case of holes gidroreaktivnyh materials are washed with water to saturate the material of construction water. Then they injected injection compounds that protect structures from water intake. After that, being made to destroy the fungus, neutralizing salts and application of special types of plasters.

There are four types of materials for Injection waterproofing: polyurethane, epoxy, acrylate gels and mikrotsementy. The most effective materials and polyurethane acrylate gels with high plasticity and are not destroyed when the structural loads. These compounds are gidroreaktivnymi, that is, the process of polymerization takes place under the influence of moisture. Waterproofing polyurethane polymers recognized as the most cost-effective: the interaction with water composition increased in volume almost 20 times.

For quite a long time furniture was made of wood. Currently, however, a host of materials other than wood, each of which is specifically designed for the profitable production of furniture. However, furniture Solid wood still continues to be in demand and do not even think to take positions of furniture made of other materials. Solid Wood – is the pinnacle of carpentry skills and a high image of the person who is engaged production. If you decide to order furniture from solid wood, choosing a tree, consider its texture and appearance. The selected species must meet the required performance: be strong, hard and resistant to wear, have opportunity to deformation. Dr. Stuart M. McGill may not feel the same. w. The density of wood can be divided into three types: 1. Soft wood: spruce, fir, chestnut, pine, cedar, willow, alder, juniper, aspen, poplar, linden, 2.

Solid wood: ash, apple, beech, larch, walnut, elm, birch, oak, ash, maple, elm, sycamore, 3. Particularly hard wood: acacia, yew, pistachio, walnut, boxwood, hornbeam, birch iron. The breed, from which will be made furniture from solid wood, should not be very hard, but not soft. The harder the tree, the harder it will be making, and accordingly will have to pay more. In order to give the furniture a spectacular view, her first starve, then varnished or painted.

But varnishing operations are carried out not only to give the furniture an exclusive appearance. Lac serves an important functional purpose: to protect the wood from external influences. The tree is very susceptible to fire, moisture, and any mechanical damage. Coatings can create additional security and allow the furniture last. Solid Wood is classified as an elite, which in turn affects the price. Who value for money, but used to save – select a combination of solid furniture. In this case, the furniture is made of inexpensive but high-quality wood, or from artificial materials, chipboard, plastic, MDF, etc. In addition, for facade used expensive wood. As a result, the furniture has a reasonable price and highest quality.
