waterproofing membrane
The first two types of web materials used for lining hydraulic seals. The technology of each material has its own nuances, but there are general rules for all of them.
okleechnoy waterproofing Technology
From the name itself it is clear that such materials are required to stick to the surface to be protected of the foundation. This is done in several steps:
- Makes surface preparation, cleaning it from dirt, leveling and smoothing out irregularities sharp corners.
- Application of primer mixes, including specific primers, increase adhesion to the concrete surface.
- Daubing foundation cements, which further increases the adhesion to the foundation.
- Directly assembling the web material by bonding a plurality of layers according to instructions attached to it.
- Application of an additional layer of mastic material to the surface.
- Apparatus protective or decorative layer of masonry or sheet materials, under which make insulation.
- Conducting drainage works with a partial backfilling of the foundation soil. To do this, at a distance of 1 meter away from the wall to dig a trench around the house, which is laid drainage pipe.
- The construction of the blind area. Its width should be 60 - 100 cm.
lining hydraulic seals
Basement waterproofing roll the liner type material has a low cost, but it is often associated with the need of the "dirty work" and the use of open sources of fire.
Useful advice! When the device blind area around the building it is necessary to make waterproofing the same material as the foundation. This will provide additional protection from water flows from the roof of their abduction away from the foundation.
Composition bitumen-polymer waterproofing material
Variety of membrane waterproofing materials
Waterproofing membranes were invented not so long ago. They are made from polymeric materials by special technology, which provides excellent protection of the foundation of groundwater and surface water. mount technology makes such waterproofing very resistant to deformation and foundation precipitate. Membrane materials are, for vertical and horizontal sealing.
Vertical exterior walls foundations experiencing significant permanent load from the surrounding soil. For such profiled surfaces meant a membrane which is able to distribute the load evenly over the surface. shipoobraznye are projections which perfectly protect the membrane from the outside pressure to the material. They accumulate moisture that flows freely into the drainage device.
Scheme basement waterproofing using roofing felt
Basement waterproofing roll materials with smooth structure is carried out while protecting its horizontal surfaces. Smooth the film does not allow water to rise through the capillaries of the soil to the base of the foundation.
Mounting films for vertical and horizontal waterproofing is made on different technologies. Studded membrane is welded construction of metal and plastic special hairdryer to the guide, fixed on the walls of the foundation. Smooth film simply overlapped and then welded with hot air.
Vertical basement waterproofing method
Useful advice!The smooth membrane, the top prokleivat geotextile. To do this, use a special glue. Such a coating protects the waterproofing from damage. Studded and moldings to protect not necessary.
Waterproofing of the basement with his own hands: video and the horizontal method description
Horizontal waterproofing arranged to protect the lower surface of the basement of groundwater. For information on how to make such a waterproofing of the foundation with his own hands, quite a lot of video. However, it helps to understand the process in detail.
Horizontal waterproofing of the foundation
As to the film falls enormous load of the entire monolith substrate must be prepared very accurately. At the bottom of the trench for the foundation is laid sand bags, which thoroughly compacted and leveled. Its thickness may reach 10 cm. Cushion geotextile placed at a density of 400 g / m2 overlap with an allowance of 15 cm, which is welded by hot air flow. Already on the trail geotextile membrane with overlapping 10 cm.
Useful advice!The joints of the membrane is welded double seam, so as to obtain a closed pocket which is then inflated by the compressor to check the tightness. The pressure in this cavity must be kept about 20 minutes. If this is not the welding procedure is repeated.
Basement waterproofing horizontal method
On top of the waterproofing material is laid another layer of geotextile, with a density of 500 g / m2. It compensates for load and provide additional protection against damage. Top stack further polyethylene film 200 microns thick. It will not allow concrete to flow to the waterproofing layer. After that, pour the foundation monolith. This can be considered complete horizontal waterproofing of the foundation with his own hands. Video of this technology makes it possible to clearly see all the nuances of the process.
High-grade basement waterproofing roll materials ensures reliable and long-term its operation that affect the durability and safety of the entire building.
