Film basement waterproofing

film materials commonly utilized in the basement waterproofing.The film for waterproofing foundation can perform several functions:

• main waterproofing layer.For this purpose, normally used diffusion film membrane permeable, but not permeable moisture;
• films for auxiliary waterproofing layer, such as thick polyethylene.It is used as an intermediate layer between the ground and the main waterproofing or between the insulation and concrete screed.

The advantages of the waterproofing membrane can be attributed to the destruction of their resistance, high quality waterproofing, comfort styling and a relatively low price.

Plastic film for waterproofing

foundation for smaller buildings with low load on the foundation can be used polyethylene film as the main horizontal waterproofing.Polyethylene - an inexpensive material, resistant to moisture and mold to temperature.The only thing that was "afraid" polyethylene film - is ultraviolet radiation, when exposed to direct sunlight polyethylene destructuring takes place over several years.Furthermore, rodents frequently damage polyethylene.It is therefore advisable to use it as the sole foundation waterproofing or waterproofing over immediately to arrange a concrete screed.

technology foundation waterproofing membrane

1. perform site layout and prepare the pit and sand cushion tape or slab foundation.The thickness of the sand cushion depends on the type of soil on the site: for heaving soils, its thickness must be at least 0.5 meters for solid ground, not prone to seasonal shifting of - about 10 cm Sand bed redistributes the load of the building to the ground, drains water from the basement.film and protects from mechanical damage.
   

   Perform layout

2. site Perform shuttering of planed boards, collecting it with bars and nails or screws so that the fastener elements were outside the formwork.This will help prevent damage to the film and is easier to remove the formwork.From outside the formwork props using slopes of the bar or boards.

3. In the prepared pit laid plastic sheeting, while the band is placed with an overlap of at least 20 cm, and the joints are glued mounting two-way tape.The edges of the film must be higher than the formwork at least 10 cm. Perform the calculation of reinforcement, reinforcement made of bar design section.For fastening fixtures use a soft annealed wire and hook knitted reinforcement.

4. mixed concrete: 1 part cement, 2 parts sand mix, dilute with water to a liquid state of sour cream and pour 1-2 small part of building rubble.In order to improve waterproofing properties of concrete can be added to the solution mixture of penetrating waterproofing.

5. Concrete thoroughly mixed and poured into the prepared formwork.Align mirror of the concrete level.If the height of the foundation is significant, to remove air bubbles using vibrator.Using metal objects can not be for the purpose, as there is a danger of damage to the plastic film.
6. film allows concrete to ripen evenly, preventing it from losing moisture through the soil.The formwork can be removed after setting of the concrete, a few days after pouring.After removal of the formwork can withstand the foundation without load for 2-4 weeks before full maturation of concrete.To protect it from drying out, it is possible to cover the top layer of the foundation covering material.
7. backfill produce soft ground such as sand to prevent damage to the film.If you plan to heat insulation of the foundation, then it should produce solutions to the adhesive without damaging the waterproofing layer.

horizontal waterproofing of the foundation under the concrete floor

Such waterproofing is most often performed on the slab foundation as a monolithic concrete slab serves as both the base of the building, the ground floor and the floor.In this case, the necessary waterproofing of the foundation not only of the groundwater, but also from leaking pipes, plumbing fixtures.If the waterproofing material used plastic wrap, then on top of it carried out a concrete screed.

1. Pour slab foundation and await complete concrete maturation.Determine the readiness of the concrete can be as follows: on the night of the foundation portion is covered with polyethylene, and if in the morning on the film condensation - the concrete is sufficiently dry.After complete maturation of concrete can begin to erect the walls and waterproofing rooms with high humidity.If necessary, level the surface: clean projections, cut protruding rebar, shells in concrete overwritten cement-sand mixture.

2. On concrete stack layer non-woven geotextile, and on top of it - plastic wrap.Geotextile creates a soft surface which protects the film from damage.Overlapping strips of material - not less than 20 cm, joints glued with a mounting tape.If waterproofing is carried out in separate rooms, the film is folded onto the walls to a height of at least 10-15 cm. Between the film and the wall is required to stack damper tape.

3. top of plastic film satisfied with the concrete floor, using the ready-made mixes for performing sub-floor.After drying screed you can start decorating.

Waterproofing of the basement membrane by a film

This is a more expensive way of waterproofing membrane, but it has many advantages.Also excellent waterproofing properties of the membrane films have a water vapor permeability, which allows you to remove moisture from the basement to the outside.They are durable, resistant to chemically aggressive groundwater, to root penetration.Roll waterproofing membrane by a film - a modern and very reliable way to protect the foundation from the ground water and atmospheric moisture.
