How to make waterproofing foundation

The waterproofing of the foundation is a system of vertical and horizontal protection of the base and walls from moisture, increasing the durability of the house. Carelessly performed isolation can lead to a large damage to household.

There are horizontal and vertical waterproofing of the foundation. The horizontal is performed during the construction of the foundation, after the construction of the house, it will not be possible to make it anymore. The base of the house is protected from moisture in two places - at the floor level of the basement and the wall connection site (base) with the wall.

At the beginning of construction on the floor of the basement, pour out fat clay with a thickness of 30 cm, sink and fill with concrete 5-7 cm. Give the concrete to frozen, stand the time for shrinkage (10-12 days you need). Concrete Fait bitumen, then put the rubroeroid on top, again apply bitumen and put the second layer of rubberoid. All fill with concrete with a thickness of 5-7 cm and scatter.

Before the construction of walls, waterproof the joints between the foundation and carriage walls, which will not allow moisture to rise up. Apply a bitumen on the surface of the foundation, put the rubberoid on it. Isolation perform in two layers. The edges of the rubberoid hanging from the plates, do not cut down, but lower down and fasten to the walls.

The horizontal insulation also includes a drainage system that removes moisture from the walls. Around the perimeter of the foundation, at a distance of 0.7 m, haul a ditch with a slope towards the collection of water. Its depth is below the level of filling of the foundation by 20 cm, the width is 20-30 cm. Plush the material with a layer of gravel with a thickness of 5 cm. Put geotextiles in the pit, wrap the edges on the walls.

In the ditch, put a special drainage tube, tilting to the drain of water at the rate of 5 mm / m. At the top, suck the gravel with a five-meantimeter layer and wrap the remaining geotextile. Plush the ground. Water falls into the drainage tube and will be discharged from the walls in a specially designated place.

With vertical waterproofing, process the vertical walls of the foundation. You can water in one way or apply several options at the same time.

Bituminous waterproofing is the most common way to protect the foundation from moisture. Buy in the market bitumen and melt in the container to the liquid state. During heating, add a mixture of 30% of spent engine oil. After applying the first layer, let him frost and apply the second.

A total of 2-4 layers of bitumen are allowed, the total layer should not exceed 3-5 cm. Treatment from the bottom of the wall to the top. The wall should be cooled by 15-20 cm above the soil. Bitume will protect it for 10 years, then starts to crack and pass water.

On the wall you can glue a rolled waterproofing material, for example, rubberoid. Fit the wall at the beginning. Cover bitumen. Then hear the runneroid and attach to it with an adhesive 15-20 cm. More expensive insulating materials (glassizole, rubitex) have a pylistster in their composition, which increases its wear resistance, elasticity, but the cost of such isolation is higher.

Excellent waterproofing is obtained after processing the walls of liquid rubber, for example, "elastopase" or "elastomix". Before working the walls, treat primer. Elastomix applies in 1 layer, dries 2 hours, unused after opening the packaging material cannot be stored. "Elastopaz" the foundation is covered in two layers, you can store the stuff remaining after work. For application, use a brush or roller, the sprayer will speed up the work.

When choosing a material for waterproofing, examine its properties. In addition to the properties, repel water, it should be resistant to various aggressive effects, for example, tolerate high or low temperatures well. The material must be environmentally friendly and safe, well to apply on the walls.
