SAMPLE CONSTRUCTION SITE: SEALING FLANGE 18533

  • The new DIN 18533 regulates the professional sealing of components in contact with the ground and their connection for all penetrations into the building
  • Liquid sealants such as PMBC (KMB) and membranes are approved for water exposure classes W1-E and W2.1-E
  • Schuck has the standard-compliant, safe solution for connecting to this: the new 18533 Sealing Flange

View into the excavation

The building is in the shell, the building seal in accordance with DIN 18533 W2.1 has already been applied to the basement wall in the form of a PMBC (KMB) * external coating. The building stands near the bank of a large river.

* PMBC = polymer modified bitumen thick coatings / Polymer Modified Bituminous Coating (former designation KMB = plastic modified bitumen thick coatings)

Pipe route for the gas and water house connection

The PMBC outer skin can be recognized by the black overspray above the dimpled sheet.

DFC (030).jpg

Exposure of the core drilling

A dimpled sheet was attached to protect the PMBC layer. The dimpled sheet is a purely mechanical protection and does not itself fulfil any sealing function.

To be able to securely connect the building entries with the Schuck sealing flange 18533 to the PMBC layer, the dimpled sheet must therefore be cut in the area around the core drillings and folded to the side.

Outside view of the core drilling

The core drillings for the house entries for gas and water penetrate the entire wall including the PMBC outer layer.

Analysis of the drill cores

The two drill cores allow a look into the wall structure. It is easy to see that the basement wall is a filigree wall / double element wall that was created using factory-made concrete formwork that was poured on site. On the upper core, the PMBC outer skin can be seen on the left. Immediately afterwards an approx. 5cm thick coarse-grained concrete layer, which can also be seen on the far right. These are the two prefabricated elements of the wall. In between the fine-grain in-situ concrete.

Important:

Since the connection between the precast element and in-situ concrete is partially defective, as can be seen from the lower drill core, where the outer part has already fallen off, special attention and special components are required here in some installation systems in order to properly seal the house connection. Not so when using Schuck Beto-Fix Plus, which is also used here and which always fills and seals the entire core drill hole.

Assembly set for gas house lead-in

Required material for the creation of the gas house entry with the special feature that two Schuck Pipes (speed pipes for fibre optic internet / FTTX) are laid directly in one operation:

  • HSP gas house transition pipe
  • Two Schuck Pipes with mounting clips and instructions
  • Wall closure set as cladding on the inside of the building
  • Schuck Beto-Fix Plus as grouting material (swelling mortar / grouting mortar)
  • Sealing Flange 18533 for the safe integration of the building entry into the existing building seal (PMBC)

Mounting material consisting of:

  • Adjustment nut to fix the system in the wall before sealing
  • Spacer sleeve to create enough space for the pipes
  • Filling funnel to pour Schuck-Beto-Fix Plus into the core bore using the 18533 sealing flange as a filling device
  • Lubricant and SW7 screwdriver

Assembly set for the water house entry

Required material for the creation of the water house lead-in: (It would also have been possible to lead the Schuck Pipes into the building with this house lead-in).

  • Water house introduction WHP
  • Wall closure set as cladding on the inside of the building, the ARO panel was painted blue at the customer's request.
  • Schuck Beto-Fix Plus as grouting material (swelling mortar / grouting mortar)
  • Sealing Flange 18533 for the safe integration of the building entry into the existing building seal (PMBC)

Mounting material consisting of:

  • Adjustment nut to fix the system in the wall before sealing.
  • Filling funnel to pour Schuck-Beto-Fix Plus into the core bore using the 18533 sealing flange as a filling device
  • Lubricant and SW7 screwdriver

Introducing the house lead-ins

Preparation of the sealing flange

After the building entries have been inserted into the core bores, the sealing flange 18533 is mounted on the outside of the building. To do this, we distribute some lubricant on the rubber insert to make assembly easier.

DFC (090).jpg

Attachment of the sealing flange

The Schuck Pipes are threaded through the two openings provided for FTTX below the building entry.

DFC (100).jpg

Positioning of the sealing flange

The sealing flange is pulled onto the building entry and the Schuck Pipes until it rests against the wall. It is important to ensure that the sealing flange is placed on the actual sealing level, not on other layers such as the dimpled sheet.

DFC (110).jpg

Preparation of sealing

The protective film is removed from the sealing cord inserted in the sealing flange.

DFC (120).jpg

The process of sealing

The sealing flange is now pressed with the sealing cord against the building seal and connects permanently. To keep the contact pressure constant and also to fix the building entry for the sealing, the adjusting nut is applied and tightened. The spacer sleeve allows the adjusting nut to be turned on the round thread jacket of the building entry without kinking the Schuck Pipes.

DFC (130).jpg

Fixation of the sealing flange

After the building entry has been finally aligned with the spirit level (inside of the building), the sealing flange is fixed and sealed on the building entry with the help of the clamp. The adjusting nut and the spacer sleeve can then be removed.

DFC (140).jpg

Preparation for grouting the wall duct

For the grouting of the building entry, the filling funnel is attached to the filling opening on the sealing flange.

DFC (150).jpg

Grouting the core hole

The corresponding amount of Schuck Beto-Fix plus is mixed and quickly poured into the filling opening. This fills the entire core drill hole as well as the sealing flange itself.

The level in the filling funnel serves as a control over the sealing. If the funnel is full and no more material flows out, then the core bore is also full and the Sealing Flange 18533 is completely back-filled.

DFC (160).jpg

Grouting mortar drying process

The filling funnel remains attached after the grouting until Schuck Beto-Fix Plus begins to set after approx. 10-20 minutes.

DFC (170).jpg

Removing the filling funnel

The hopper is removed and cleaned. As a reusable tool, it can be used together with the adjusting nut and the spacer sleeve for other construction sites.

DFC (180).jpg

Sealing of the filling opening

The filling opening on the sealing flange is closed with the cap and secured with the tightening strap.

The building entry is now installed and sealed in accordance with DVGW VP601 and DIN18533 standards. In addition, the house connection is also radon-tight, which recent tests confirm and is becoming an increasingly important feature for installation materials.

DFC (190).jpg

Radon-tight installation of all building entries

The water house connection is also installed with the 18533 sealing flange in conjunction with Schuck Beto-Fix Plus, in compliance with the standards , securely and radon-tight.

Thanks to the Schuck round thread jacket, which is always the same for gas, water and electricity house entries from Schuck and only differs in the nominal widths, the available accessories can be used for all media.

Detail view of implementation of speed pipes

Two openings for the Schuck Pipes are integrated in the sealing flange 18533 , which allow a standard-compliant seal when laying with a media line. (We expressly recommend using only the Schuck pipes here, other speed pipes are not designed for pouring and lead to leaks).

Completion of the construction site

The Schuck building entries are installed cleanly and securely. Thanks to well thought-out assembly technology and the highest quality, Schuck building entries enable safe and long-lasting operation.
