The DIN standard DIN 18195 building waterproofing regulates the protection of buildings against moisture and water. It was largely replaced in July 2017 by the series of standards DIN 18531 , DIN 18532 , DIN 18533 , DIN 18534 and DIN 18535 . The current version of DIN 18195 is only a conceptual standard.
The standard consisted of the following parts: (As of June 2012)
- Part 1: Principles, definitions, assignment of the types of sealing
- Part 2: fabrics
- Part 3: Requirements for the substrate and processing of the substances
- Part 4: Sealing against soil moisture (capillary water, retained water) and non-standing seepage water on floor slabs and walls, dimensioning and execution
- Part 5: Sealing against non-pressing water on ceiling surfaces and in wet rooms, dimensioning and execution
- Part 6: Sealing against externally pressing water and accumulating seepage water, dimensioning and execution
- Part 7: Sealing against water pressing from inside, dimensioning and execution
- Part 8: Sealing over movement joints
- Part 9: Penetrations, transitions, junctions and terminations
- Part 10: Protective layers and protective measures
- Supplement 1: Examples of the arrangement of the seal
- Part 100 & 101: Changes planned
For flat roofs that were not in use , DIN 18531 roof waterproofing in addition to the flat roof guideline already applied before 2017 . DIN 18195 also did not apply to water-impermeable solid components such as white tubs .
DIN 18195 differentiates between four types of waterproofing depending on the action of the water in the ground on underground spaces, often also referred to as load cases in the literature :
-
Non-standing seepage water in permeable soils (e.g. "highly permeable" soils with a permeability coefficient k-value> 10 −4 m / s), type of waterproofing according to part 4
- A thick coating of 3 mm thickness , a plastic sheet (film) or bitumen welding sheet is sufficient here . No drainage is required.
-
Damming seepage water (recognizable by the formation of puddles in loamy soil), type of waterproofing according to part 6
- The most common case if there is no groundwater. A thick coating in two layers is required here, with embedded fabric (if required in the test certificate). Newer sealing methods must be approved according to Part 6. The dry layer thickness must be at least 4 mm (i.e. after drying for solvent-based bitumen coatings). In addition to the execution of a black tank with bitumen welding sheeting, sealing with PVC / fleece sheets ( K tank ) and waterproof concrete (" white tank ") is also possible. Slight signs of moisture penetration can usually not be ruled out with waterproof concrete.
-
Pressing water is u. a. assumed if the highest groundwater level is less than 30 cm from the top edge of the floor slab and the foundation is lower than 3 m; If the foundation is less deep, the cohesive soil should be absorbed by temporarily standing water ; Type of seal according to part 6
- A thick coating against pressing water must be carried out according to the manufacturer's instructions in at least 2 work steps and have a dry layer thickness of at least 4 mm. Alternatively, self-adhesive strips can be used or the K-tub can be used.
-
Water pressing from inside [negative sealing]; Type of sealing according to part 5
- 1. Moderately used wet areas in private areas
- 2. Highly used wet areas in private or commercial areas
- The drainage takes place via a gradient and suitable floor drainage or gutter systems, if necessary with a second drainage level. Specifications for the minimum distance between penetrations of the seal (e.g. in the case of frequently occurring pipelines) must be observed in order to be able to carry out the seal in accordance with the standards.
Sealing measures require that the subsurface is sufficiently firm and conforms to standards. This is often not the case with old buildings.
