The basement is one of the components of the house that is most susceptible to direct contact with water. Therefore, it is necessary to provide it with proper deep basement waterproofing so that moisture does not penetrate into the foundation, the walls do not appear on the floor inside the basement. How to make such basement waterproofing? NO Water System Experts will help us figure this out. NO Water System Experts has many years of successful experience in Quebec and will help you successfully solve all your questions about basement waterproofing.
The problem of waterproofing the basement disappears if we do not build it. However, basement is often necessary. This is due to the relief of the site and its size, on which we make houses. It is difficult to construct a building in a small area, which takes into account all the premises we need, including utility ones. In this case, the basement is irreplaceable.
Basement and basement waterproofing starts during the design phase and continues through the construction phase.
Repairing poorly executed insulation or drying wet walls is not only unnecessary, but costly and time-consuming.
Types of waterproofing
External waterproofing
If the house will stand on a strip foundation, you should use 3 types of insulation – 2 horizontal and 1 vertical. The first horizontal one is made on continuous supports. It must be applied in the right amount so that it can be combined with two other waterproofing materials, which will ensure perfect tightness of the entire structure. To prevent water infiltration onto the floor, a horizontal floor insulation is used – it is placed on structural concrete slabs. The latter is vertical wall insulation. If the building is placed on a foundation slab, then the matter is easier. It is enough to lay vertical and horizontal insulation and connect them together.
Waterproofing basement from inside
If you have a problem with moisture or groundwater in your basement and you cannot dig a foundation, you can make your basement repairs from the inside. This kind of solution can be carried out even if there are leaks in the walls and floor. Waterproofing from water under pressure tightness for many years. Vertical waterproofing can be covered with ceramic cladding or a hydrophobic plaster system.
The main danger to the basement
The main danger to the basement is groundwater. Groundwater will easily find cracks and penetrate inside, reinforced basement walls and lead to the formation of mold and mildew. Therefore, foundations must be properly insulated and a drainage system must be installed around the building. Saving on materials is a trap. They must be of high quality and durable, since then it is difficult to replace them. The type of soil on which the water impact is located. Permeable soils such as sand do not retain water in their structure for a long time. The situation is different in cohesive soils such as clay. Slime is a way to retain moisture for months, exposing the foundation to prolonged exposure to moisture. Therefore, soil and water tests must precede each design. The most important information obtained from them is the determination of the stabilized groundwater level.
Materials to use for waterproofing
The materials used in waterproofing have excellent strength and resistance to the joints present in the ground. You should not save on the materials of waterproof barrier for basement.The best insulations can be expensive, but are worth investing in because they will reliably and permanently protect your building. If the waterproofing is damaged, replacing it is difficult and costly, so you should immediately purchase the most durable materials.
According to the material, the waterproofing used in the soil is divided into:
- bituminous – thin-layer coatings (liquid or semi-liquid based on asphalt), thick coatings and roll coatings (roofing felt and self-adhesive membranes);
- mineral – coating (sludge) and roll;
- plastic – roll films and membranes.
Secondary insulation
The existing building can also be waterproofed both horizontally and vertically. For this, you can use the injection method. It allows horizontal insulation from the inside of the building without the need to excavate the foundation walls. Such waterproofing interrupts the capillary rise, which leads to dampness of the walls and, as a result, the appearance of mold and mildew. Injection – holes are drilled in the wall and filled with an injection. Vertical insulation is similar to horizontal insulation. It is used when it is not possible to dig out the basement walls and insulate them from the outside.
House drainage systems
Moisture in the foundations of a house or water seeping into the basement – these are the troubles we will have to face if we do not take care of proper drainage around the building. How to carry out tape drainage and when should you decide on linear drainage?
What is a Ring drainage?
Ring drainage of a building should be carried out at a high level of groundwater, when they are only a few tens of centimeters below the surface, and when we live in a private house with a basement. It is also necessary to drain clay areas that are poorly permeable to water.
What is Linear Drainage?
On the other hand, linear drainage is used on the ground – it handles rainwater well – so that it does not run into roadways or impervious soil, creating puddles.
