The question of the need for floor waterproofing is relevant in two cases when moisture enters the room from below or when it condenses on the walls and then drains to the floor. Thus, the device for floor waterproofing is necessary in rooms that are located directly on the foundation, above the cellars or in which the humidity level of the air periodically increases, for example, in the bathrooms.

Waterproofing the floor with their hands

Depending on what materials will be used and due to what the floor waterproofing will be carried out, the price of these works can differ substantially. The simplest and cheapest option can be considered the use as a waterproofing material of a polyethylene film or roofing material.

This method has been used for a long time, but it requires the subsequent creation of a screed on the floor for normal use of the room. To begin with we will consider it, and then we will understand with more modern methods. Before starting work, it is necessary to completely clean the floor from the coating, whatever it is, and also remove all construction debris and dust. After that, a waterproofing material is laid on the base.

Traditionally, for these purposes, ruberoid is used, because it is cheap enough. However, to date, waterproofing films are available on the market, which have the best technical and operational characteristics and can last longer. In cases where it is required to lay the waterproofing overlap, all joints should be carefully smeared with mastic.

It should also be noted that the material itself is laid in such a way that its edges extend to the walls to a height of 10-20 centimeters. Further along the edges all the material must be fixed with paint tape. After the completion of work, on top of this material, you can make a screed or lay some floor covering.

In those cases where the waterproofing of the wooden floor in the bathroom, this option is the most attractive. Naturally, before starting work, remove all the boards, then lay the waterproofing material and return the cover to its place. In order to protect the wooden coating from the negative effects of moisture, it can be additionally covered with stain or paint.

Waterproofing of the floor in the apartment with modern facilities

Also for the implementation of waterproofing liquid materials can be used, starting from traditional bitumen-rubber mastics and finishing with special penetrating solutions. The use of bitumen-rubber mastics has a number of advantages in comparison with the use of ruberoid. In particular, liquid materials are much more resistant to moisture, serve longer, and are even "laid" on the base, which avoids the presence of joints.

At the same time, such mastics are much more difficult to use, because they are applied only in a hot state, and in order to melt them, a temperature of 140 degrees is necessary. In addition, when working with this kind of materials, special care must be taken and avoided not only on the body, but also on outside objects, since it is almost impossible to clean them.

As for the algorithm itself, the only difference from working with a ruberoid is the need to allow the material to dry before laying a floor covering on it. Literally a couple of years ago a variety of waterproofing mixtures of deep penetration appeared on the market. This type of materials is applied in a cold form, penetrates the screed to a depth of up to 20 centimeters and, at the same time, forms crystals in it that are perfectly resistant to moisture.

Thus, in those cases where waterproofing is carried out directly on top of a concrete screed, such mixtures are an excellent way out. The main disadvantage is their price, as well as a small prevalence in the market.
