First of all, it is the key to the durability of your home. 00:00 - 0:11 waterproofing of the foundation: why? 0:11 - 1:12 how does water affect the foundation? 1:12 - 1:46 waterproofing and drainage 1:46 - 2:35 how to calculate a foundation in 5 minutes? 2:35 - 2:42 types of waterproofing. Vertical waterproofing 2:42 - 2:51 horizontal waterproofing 2:51 - 2:56 blind area for water drainage 2:56 - 6:30 what to waterproof with? One of the most important indicators in construction is the groundwater level. This is not a constant value. In spring, groundwater fluctuations can be several meters. If the water rises high, that is, is located at a depth of less than one meter from the bottom of the foundation, then it is better to do waterproofing both from the inside and outside. When a building is erected on clay soil, in addition to waterproofing, drainage will also be needed. What types of waterproofing are there? Vertical - this is when the foundation walls are insulated entirely, above and below the ground. Horizontal - to protect the lower base of the foundation at the point of contact with the ground, or to insulate the joint between the base and load-bearing walls. A blind area that is made to drain rain and melt water from the foundation walls. What to waterproof with? The simplest, but not particularly reliable method is coating. This is when bitumen mastic is applied to the concrete walls in a layer of 3-5 centimeters. In this way, we close the pores of the concrete and do not allow moisture to penetrate inside. In terms of reliability, this is not a very good option, since after drying, the mastic becomes sensitive to mechanical damage. And the main disadvantage: such waterproofing needs to be renewed approximately every five years. There is a more exotic way to protect concrete from moisture: injection waterproofing. When a special waterproofing solution is injected into holes drilled in the walls through injection packers. The solution soaks the wall to a certain thickness, after which the pits are closed. This method is often used to restore damaged waterproofing. The next type of waterproofing is mounted. When a lock is created around the foundation using protective mats, which closes off access to moisture. For example, granulated bentonite clay is placed between cardboard or geotextile sheets. Over time, the cardboard will decompose, and the buried part of the foundation will be surrounded by a waterproof layer of clay 1-2 centimeters thick. Are there any disadvantages to this method? Of course. This is the complexity of the work, the cost of materials, but the method is reliable if performed by specialists. If the previous methods seemed complicated or very expensive, then adhesive waterproofing is definitely for you. . The use of roll adhesive material does not require any calculations and jewelry precision. The foundation is waterproofed with roofing felt, roofing felt, glassine, hydroisol. They can be glued in one layer or in several. This is done with the help of an adhesive composition, bitumen mastic, as well as a fusion method with a burner and cold bitumen. Waterproofing with a membrane is gluing a special self-adhesive material to the surface of the foundation, which can also be mechanically fastened with dowels. This method is often used as an additional one. Penetrating waterproofing is carried out with special mixtures and solution. The foundation structure is saturated with a solution, which crystallizes when dry. As a result, moisture cannot penetrate the foundation. Plaster waterproofing is rarely used in the construction of residential buildings. If even one crack appears on the plaster, moisture will inevitably penetrate and destroy the foundation walls. The paint type of protection against moisture ingress is applicable to all types of foundations, but is more suitable for pile-screw structures. The paint will prevent the appearance of small cracks, and also protect the piles from corrosion. The price is very attractive in this method. In addition, you do not need a construction diploma to process the surface. Several layers and a coating thickness of four to six millimeters is quite enough. It is very important to apply liquid waterproofing correctly. It must be really liquid. Thus, the treated surface area will not contain seams. In accordance with current standards, the consumption of bitumen mastic per square meter will range from eight hundred grams to two kilograms two hundred grams of mastic with a waterproofing layer thickness of 0.7 MPa. All strokes when applying the mastic should be made vertically. The mastic is applied in three layers. Each is applied only after the previous one has completely dried.
