Sealing systems

Basically dependent on the masonry. However, we recommend using it in a casing.

Curaflex® sealing inserts are maintenance-free. If the assembly is correct, it is not necessary to retighten the hexagon nuts.

Depending on the circumstances, the following accessories are available:


A) For single-layer loose, hard or thin (<2 mm) sealing sheeting, EPDM allowances 1775 (2 pieces of EPDM cut, adapted to the selected fixed-loose flange system) are recommended


B) For thick coatings (for example KMB), the accessory Curaflex 1776 (foam rubber spacer rings and a glass silk fabric for incorporation into the KMB) may be recommended, if necessary, an additional punch.

In principle, in the case of core drilling in reinforced concrete, there is a duty to cut reinforcements, but also if the concrete cover is undershot to take measures to prevent the corrosion of the reinforcement. For this reason, but also to correct further defects, the use of Aquagard is recommended.

As a rule, the GGV version is sufficient. However, if the gasket insert comes into contact with acidic or alkaline water, drinking water or aggressive media, to use a different material. We can make binding statements for you when you return the completed resistance checklit GERMAN version. We are pleased to to make you an appropriate offer.

Yes, it is possible to manufacture special versions. Submit the diameter of your lines and the core hole / casing pipe to us in advance. We check the technical feasibility in-house.

No, here we need the exact cable diameter in mm. The articles are always manufactured individually for your application after receipt of the order.

It is possible to order additional holes from the factory, in which the drill core remains in the rubber seal at no extra charge. However, this must be clearly stated in the order. But here too we have to know in advance which cable diameters are to be carried out later.

According to the guidelines of the German Institute for Building Technology (DIBt), our sealing inserts belong to the building products according to list C or according to the model administrative regulation for technical building regulations (MVV TB) according to part D. These products do not have any evidence of usability or conformity. These products are therefore not subject to approval.

As far out as possible (water side). For element walls in the area of ​​the in-situ concrete or in the sealing part of the wall (information on this from the manufacturer). If it is not clear, it is recommended to use sealing systems that seal both in-situ and ready-mixed concrete.

Fire protection systems

In accordance with the model pipe system directive (version 03/2000), flammable pipelines with a pipe outside diameter of> 32 mm must be sealed off with a R90-tested bushing.

Commercial non-combustible cement mortar, gypsum mortar or concrete of building material class DIN 4102-A can be used.

Yes, using the so-called "stand-alone solution"
lease do not hesitate to contact us for further information: 0049 4207/91 66 300

No, Inject BS + K10 is only suitable for fire protection partitioning of ring gaps.

Yes, e.g. the Curaflam fire protective collar XS Pro. It is installed on both sides in front of the wall or on one side under the ceiling and can be attached both later and during pipe laying.
