Application of floor waterproofing in the apartment

To create a good floor, in addition to the screed, you need to perform work on the hydraulic insulation and noise insulation. They are necessary for the possible penetration of excessive moisture from the basement, the lower floor, as well as to protect the floors from potential water leaks in case of accidents in the plumbing or heating system. In this article we look at the basic and most acceptable types of waterproofing of the floor in your apartment before screeding. They are uncomplicated and available for self-application.

Types of hydraulic insulation

For apartments, you can use several convenient and uncomplicated types of waterproofing with noise insulation. Among the most famous are the laying of a vapor-hydro-insulation film before the screed. The film allows you to create a layer that well protects the floor from moisture and water vapor penetration and floor slabs from water leaks. In addition, a good noise insulation is obtained. The next popular type for apartments – it is smear waterproofing. It is performed with special mastics with bitumen or rubber, which are applied in several layers. Insulation with bitumen is especially convenient because it can effectively close all cracks and crevices in the base of the floor of the apartment and get a quality soundproofing. Another method is the impregnation of concrete slabs with special solutions. This is a newer technology that is gradually gaining popularity in apartment renovations. It began to spread rapidly due to the effectiveness, good noise insulation, ease of use and manufacturability. Concrete slab is impregnated with a penetrating solution over its entire surface. The liquid is able to penetrate into the smallest pores where crystals grow. As a result, the pores are clogged and stop letting moisture inside the slab.

Insulation based on roll materials

Before starting work, a damping tape is laid around the perimeter of the room, which will compensate for the expansion of the screed during temperature fluctuations. For installation, an adhesive layer, dowels are used. Before creating waterproofing, it is necessary to level the base. To do this, all cracks are filled with concrete mortar or covered with sand. If you plan to use polymer-based materials, it is not necessary to pre-treat them with a primer. If you want to make insulation with a reserve, you can impregnate concrete with a primer. For the laying of conventional roofing felt it is necessary to treat the surface with primer. The prepared floor is covered with cut strips of material with an overlap of up to 10 cm. The wall is given an overlap of about 15 cm. If a roofing felt is used, it is glued to the base with bitumen mastic. Do not forget to also lubricate the joints to connect the strips with each other. Rolled glass insulation is fixed on the basis of heating with a gas burner. Polymer films are placed on the floor overlapping and welded with a construction hair dryer. Layering depends on the material used. If for roofing felt it is necessary to apply a two-layer laying, the films can be laid in a one-layer method. After the installation of waterproofing, you can perform screed. After the mortar hardens, the parts protruding around the perimeter of the room are cut off under the floor level.

Omparazochnaya damp-proofing

Before starting the work, the concrete base is prepared. It must be cleaned from debris and dirt. Particular attention should be paid to sharp particles, oil stains and other active chemicals. They can react with the coating and lead to its destruction. Oprimary waterproofing is carried out with bituminous mastics or on the basis of rubbers. Cleaned surface is covered with a primer (primer), designed for this type of mastics. It is better to buy a primer and mastic of the same manufacturer. It is better to apply primer with a broad brush in one layer. Be sure to dab all areas and corners. Drying usually takes a few hours. For mastic also take a broad brush. Application with a roller also gives good results. After the first layer dries, a second pass is made. It is better if the direction of motion of the roller will be different. If it is planned to use metal reinforcement, plastic guides are used for the reinforcement. Bare metal ends in operation can damage the delicate surface of the insulation layer. To ensure that the waterproofing layer of the floor in the apartment is reliable and gives good noise insulation, you can use more than one type of treatment and protection of the surface. If the apartment is located on the first floor and there is a basement underneath it, you can first impregnate the floor slabs with a penetrating solution and then perform bitumen or roll insulation.
