Waterproofing the floor in a wooden house: what materials are used and the procedure for work

Pasting means include:

• roofing felt is the most popular method;

• roofing paper, which is still used, given its cheapness, but it should not be used as protection for the main structures of structures;

• glassine - thick cardboard impregnated with a bituminous binder;

• bitumen-impregnated polymer materials.

Plastering

This waterproofing is a coating type.

Now there are many means of protection against moisture - these are solutions in which, in addition to asphalt or cement with sand, there are additives that impart useful properties.

The most common among them: liquid glass, sodium aluminate, celestite.

Plaster insulation is "spread" on the foundation.

Paint shop

Paintable waterproofing contractors NY can be hot or cold and involves applying a complex layer 1-1 mm thick from protective equipment. The most suitable are hot polymer bitumen and cold epoxy rubber coatings. Such a foundation waterproofing device is widely used to protect against capillary moisture.

Paint insulation is thinner than plaster insulation.

Mounted

Various fiberglass plastics, rigid polyvinyl chloride, precast concrete products are used for the mounted waterproofing. The disadvantage is the high cost and laboriousness of the preparatory work. Such insulation is used when the use of conventional waterproofing is not possible.

Injection

This waterproofing method is based on creating a membrane between a layer of moist soil and a foundation. The method consists of introducing a hydrophobic gel into the structure, which, when solidified, closes all the pores, preventing water penetration.

Do-it-yourself foundation waterproofing

Foundation waterproofing is a hot topic for those who are planning to build a house or face the problem of damp walls and floors. This article will help you understand the technology for performing work, determine the choice of the required material, and also find answers to the following questions:

• Why do the foundation collapse and its performance decreases?

• Why do you need waterproofing? Is it possible to do without it?

• What do waterproofing materials protect from?

• How to waterproof yourself?

• What is the best technology to use?

• How to choose a waterproofing material for your foundation?

What is foundation waterproofing? Why is it needed?

The foundation is as essential a structural element of a building as a roof or walls. Ideally, it should be durable, strong, stable.

The main component of the building's support is concrete, and it is it that is most susceptible to the negative influence of melt and rainwater and groundwater. Being in constant contact with concrete, moisture gradually destroys the foundation, so waterproofing contractors in NY is an essential stage in the zero cycles. Protection of the concrete base is especially needed if you plan to build a basement, garage, or basement.

The capillary-porous structure of concrete makes it vulnerable and allows liquid to penetrate unhindered. Like a sponge, the material absorbs significant volumes of water, which does not evaporate, thereby contributing to the growth of fungi and the appearance of mold.

The thermal insulation properties of damp walls are significantly reduced, and the interior decoration deteriorates. Unfortunately, this is only the tip of the iceberg: upon contact with moisture, the support reinforcement corrodes intensely, turning into rust, due to this, an intense internal destructive pressure is formed. In winter, the water in the capillaries of concrete turns into ice, and its crystals destroy the foundation from the inside.

How to waterproof the foundation with your own hands?

To independently apply a waterproofing coating to the foundation, you need to find out what type of soil on the site and what grade of concrete was used to construct the support. For detailed information on the selected waterproofing materials, please contact the manager of our store. It will be good if, before starting work, you consult with a specialist and use his recommendations. By following the technology described below and adhering to a specialist's advice, you will perform the job of protecting the foundation from waterproofing.

This method works only at the stage of construction of structures; in the future, its use causes many inconveniences. For the foundation of concrete and tape types, waterproofing work is carried out in the following places:

• lower than 15-20 cm from the basement floor level or its level;

• where the foundation and walls are connected, as well as on the plinth.

Before starting work, preparatory measures are carried out: first, coarse sand is poured onto the bottom of the pit, and then a layer of crushed stone (20-40 cm), a classic footing is carried out (a layer of concrete 5-7 cm is poured). The resulting base should dry well and stand for about 10-15 days. The concrete has two main functions and it provides a reliable and level base to which waterproofing contractors New York will be applied and prevents fresh concrete from losing water and sinking into the ground. After that, weld-on roll waterproofing is made with Uniflex and Technoelast materials, as well as their analogs.

Foundation waterproofing materials

• Lubricating waterproofing ( Mastic ) is the most extensive group, including rubber, bituminous, polymer, and waterproofing mastics. The group's name implies the application of mastic with a spatula, roller, or unique brush. These materials attract a relatively low price, but the base's coating requires a lot of time. The durability of such a coating is the lowest among similar materials. The final coating thickness should be 5 mm. For almost every type of foundation, coating mastics are used as the main or additional component.

• Liquid rubber (sprayed) - more modern materials such as Aquablocker are applied using a spray gun. In addition to the main component, bitumen, the emulsion contains latex polymer particles. Due to the improved composition, the work is performed much faster, and the result is longer and of higher quality. The sprayed compound is suitable for MZLF, LF, ZLF foundations.

• Roll materials include waterproofing based on paper, polyester, and fiberglass. The active ingredient is a polymer or bituminous component. Such waterproofing is more expensive than the previous groups' materials, but it lasts longer and better. When performing work, the technology of fusing or gluing rolls is used. These materials are suitable for all types of foundations.

• Due to their high cost, penetrating compounds  ( Hydro last Mixtures ) are rarely used for complete waterproofing of concrete support. Most often, these materials are used for the local elimination of problem areas in basements. The composition components penetrate the concrete's depth at a distance of 15-20 cm and turn into strong crystals. This feature of the substance allows you to protect concrete from moisture and protect the foundation from the destructive effects of groundwater.

• Plastering materials ( Ceresit, Plitonite, Knauf ) - these dry mixtures belong to the coating but differ in their constituent elements. The application technology is similar to the coating technology, and to enhance the protective effect, and it is recommended to use a protective mesh. You can use plaster mixes for sealing joints between foundation slabs or leveling any concrete base's surface before applying waterproofing film.

Conclusion

In our climate and soil type, foundation waterproofing is a necessary condition that must be met to preserve the load-bearing support of the building, taking into account the type of support, soil characteristics, and the remoteness of groundwater.
