The reliability, durability, and quality of the future building directly depends on your decision on how to waterproof the foundation.
Proper waterproofing of the foundation will not only prevent many unpleasant moments inside the building, such as flooding, wall dampness, mold and mildew. It will also extend the durability of the structure, strengthen its resistance to loads and natural disasters.

Since the foundation is an underground element of the building, it is subjected not only to higher loads, but also to excessive moisture.
Waterproofing for the foundation is the protection of the underground concrete foundation of a building from the negative effects of groundwater and precipitation that penetrate the upper layers of the soil. It creates a dense waterproof layer that protects building structures from moisture penetration.
One of its most important functions is to protect the building's foundation from destruction due to the penetration and accumulation of water in the foundation pores. This leads to the spread of moisture to the walls of the building, which in turn causes mold, fungus and dampness inside.
So if you don't want to face such consequences of negligent construction, take care of waterproofing at the stage of building construction. After all, a high-quality foundation is the key to the stability and durability of the entire structure.

Foundation insulation can be performed in a variety of ways. Their choice depends on how long and strong the impact of moisture on the foundation will be. It also depends on the loads it will have to withstand in the future. Therefore, before deciding which type of waterproofing to choose, it is necessary to analyze the hydrological situation of the future building.
First of all, you need to understand the depth of the foundation and the presence of groundwater at that depth. At the same time, you need to take into account the climatic conditions of the area, i.e. how frequent and abundant precipitation is. It is also important to pay attention to the construction site itself, whether it is located on a high or low ground. And then monitor the availability of high-quality drainage systems.
Depending on the situation, a choice is made about a specific type of foundation waterproofing.
This type of waterproofing involves covering the foundation with rolled protective materials. In particular, the outer surfaces are covered with bitumen or polymeric materials, and roofing material and fiberglass fabrics are also used. Pasting waterproofing is often used during the reconstruction of already built structures. It can be applied over existing waterproofing.
It is important that the weather is dry and the temperature is above freezing, and the surfaces to be treated are perfectly dry. After all, even a small amount of water will lead to insufficient adhesion of the rolled materials to the concrete. This means that the waterproofing will be unreliable.
For this type of waterproofing, a special waterproofing mixture is used. It consists of Portland cement, quartz sand, as well as special additives and active chemical elements. This solution penetrates deep into the foundation structure and strengthens it. The insoluble compounds created in this way inside the foundation protect it from moisture. It also enhances the frost resistance of the foundation and its protection against mechanical damage. This is a thorough method of waterproofing the foundation.
The essence of this type of waterproofing is that a protective solution is injected into the seams, cracks, and pores of the foundation using a kind of injection. These are the areas that need protection from water the most. The solution itself is prepared on the basis of epoxy, polyurethane, and acrylate resins.
The essence of this method of insulation is that the surface of the foundation is coated with a certain type of coating, creating a seamless additional layer of water protection. There are many options for such an external coating, which differs in its composition: polymer, cement, bitumen, liquid rubber, mineral filler, etc. However, the essence of their action is the same. However, such protection is effective only when applied from the water pressure side.
In essence, this type of waterproofing is similar to coating. However, in this case, other materials are used: special plasters and various paints. This is a simple and fairly cheap way to protect the building's foundation.
However, this option is not very reliable and durable and at best retains its waterproofing properties for up to 5 years.
Reliable waterproofing of the foundation requires unambiguously contacting specialists and using high-quality materials. However, understanding how to properly waterproof the foundation will allow you to avoid mistakes at the beginning of construction and control the quality of all work.
