As you know, groundwater can destructively affect the foundation of a building. Moisture after contact with the material will penetrate into its structure, and then freeze and thaw when the temperature changes. In this case, water particles will destroy the fragments of the foundation. For several years of such operation, the foundation of the building may become unusable, after which the entire building will begin to collapse. In order to eliminate such negative consequences, you can use the waterproofing method, but it is important to choose the right material and apply it according to technology.
Base Protection Materials
Surfacing waterproofing can be an excellent solution for protecting the foundations of buildings. Moreover, this method is one of the most effective, and this result was achieved thanks to the appearance on the construction market of rolled materials that are reinforced with polyester and have high tensile strength. If we compare them with roofing material or roofing material, then the former do not rot, are characterized by higher water-repellent characteristics and a long service life. The most common surfaced materials for waterproofing are: “Isoplast”, “Mostoplast”, “Ecoflex”, “Tekhnoelast”, they are manufactured in Russia, but you can also choose products from other manufacturers. For example, Aquaizol and Spoliizol are available in Ukraine. More expensive, but no less high-quality are the Italian Testyudo, as well as Helastopley. Synthetic products, such as polyester, fiberglass and fiberglass, act as the basis of these coatings. Surfaced waterproofing is installed on the foundation in two layers. The material will protect the surface from water, and when backfilling, mechanical impact on the waterproofing surface should be excluded. Such protection can be a geomembrane.
Recommendations
For waterproofing work, it is recommended to use materials that are resistant to corrosion. You can apply rubber-bitumen mastic, which is the primary protection, or materials for secondary protection. In the latter case, the surface is glued with rolled material, and it is recommended to do this at the stage of concrete hardening, when the construction of the walls has not yet begun.
Surfacing waterproofing of the Technonikol brand
Weldable waterproofing "Technonikol" is presented on the market in a wide range, this material you can recognize by the following markings: "Solo", "Vent" and "Technoelast". A cheaper variety is Bikrost. However, any of these materials will help to waterproof the foundation as high as possible. Products are divided into classes Premium, Business, Standard and Economy. Among the first are Tekhnoelast and Vestoplast, which are bitumen-polymer materials made from high quality raw materials. With the help of such waterproofing, the foundation can be protected from groundwater, and the operation of the material can be carried out in difficult conditions.
Using liquid waterproofing for the floor
Liquid waterproofing can be represented by rubber, which is applied manually. This eliminates the need to contact specialists. Liquid rubber can be used to create a water barrier on the floor and walls, this applies to bathrooms, bathrooms and adjacent rooms. Thus, it will be possible to protect the concrete surface from destruction. If liquid waterproofing will be applied to a large surface area, then you can use the method of spraying a bitumen-polymer two-component composition. This involves special equipment. If you have to process small areas of the floor, you can apply a single-component composition manually. The bitumen-polymer composition is water-based and odorless, environmentally friendly for animals and people, and also does not cause allergic reactions. The concrete base must be prepared, for this, the screed is poured or the surface is simply leveled. The base is cleaned of dust and dirt, and then you can start applying bitumen-polymer soil, which will increase the adhesion ability of liquid rubber. The waterproofing device in the next step involves waiting two hours after priming, only then you can start applying liquid rubber, which is distributed using a brush or spatula. The layer should not only be on the floor surface, but also go onto the walls, the height from the abutment border should be 20 cm. The material consumption when applying the mixture in the bathroom will be about 3 liters per square meter. After the polymerisation of the rubber is completed, which will happen in about 48 hours, a thin screed can be equipped.
The technology of using roll-up surfaced waterproofing in the field of foundation
Before starting work, the foundation must be cleaned of fine particles, dirt and cement milk. Sharp edges and corners must be cut so that they do not damage the material. A primer is applied to the base. Using this layer, it will be possible to increase the adhesion characteristics of the surfaced waterproofing. Moreover, this mixture contains the remaining fine dust and fills the pores and microcracks, hardening the surface. Surfaced waterproofing should be applied to the surface protected by a primer, which will favorably affect the speed of work. After 24 hours, the surface may still remain sticky, the drying time of the composition will depend on the external conditions and the type of primer.
Surfaced material should be heated in the back side using a blowtorch or gas burner. In the course of work, the waterproofing material should be pressed to the base, gradually unwinding it.
Methodology
If the surfaced waterproofing is fixed on vertical surfaces, then it is necessary to roll out the roll from the bottom up, with the canvas should be horizontal. If you want to stack them in their entirety, you can use mechanical feed through a block system. The lower canvas should be overlapped by the upper 100 mm or more. But the surface should be covered to a height of 300 to 500 mm above the ground. Surfacing waterproofing, the installation technology of which implies the need to fix the upper part to the base mechanically, is the most effective. If horizontal and vertical waterproofing in the complex were used, then the canvases are necessarily combined. The joining places should be additionally pasted over with roll material, the width of which is 300 mm, a similar reinforcement is necessary when gluing the material onto complex sections according to the type of internal and external corners, as well as the places of entry of utilities.
Installation of waterproofing on the roof surface
Rolled materials for roofing are also used quite often today. Such technology is applied in all regions of Russia, use in areas with severe climates is especially justified. When carrying out restoration repairs of the old coating, it is necessary to apply the deposited roof in one layer. If the waterproofing device is being conducted for the first time, then you can not do without two rows. A material preheated with a propane burner is laid on a plane . There is another installation option, which consists in gluing the first layer using mastic or mechanically.
Conclusion
It is noteworthy that roll waterproofing for the foundation can be equipped both on a new and an old building. However, subsequently, it will be a little more difficult to carry out these works, because you have to dig a trench, and then clean the surface of the base from dirt and soil.
