K-System

K-system is an abbreviation for catastrophe protection system (german: Katastrophe = catastrophe). This system does not require any preparatory construction measures on asphalt up to a flood height of 1.30 m and can therefore be applied flexibly in different locations.

 

The special feature of the K-system is that the water pressure applied by the flood water makes a positive contribution to the system's stabilisation.

The protective wall only consists of the following 4 components; there is no mix up during assembly.

1. K-trestle
2. Dam beam
3. Pressing tool
4. Ground seal

Due to its modular design, the system can be extended in any directions depending on the requirements and also optimally adapted to the topographic conditions. The system is capable of compensating ground unevenness of up to 15 mm, curves in the terrain with radiuses larger than 20 m and height differences of up to 190 mm. Please note that selective that exceed these dimensions can easily be sealed with sand bags and foils. Experienced flood fighters are aware of and familiar with this type of flood combating, which provides almost limitless room for improvisations.

Wall connections and corner solutions are standardised or specially adapted to local conditions.

Wall connections

K-trestles, dam beams and pressing tools consist of robust and durable materials like aluminium (AlMgSi) and stainless steel (V2A; 1.4301). All sealing joints are sealed with proven and advanced seals made of PVC foam and EPDM. Due to the high-quality materials, which have been used in flood protection for many years, almost any service life can be achieved with proper storage. This way, the system can be applied any number of times without requiring replacement purchases.

The setup and dismantling of the system requires only limited personnel and time expenditure. Depending on the flood height, 4 to 8 persons can erect 100 m of protective wall in one hour. Due to the fact that the protective wall consists only of 4 components, which cannot be mixed up during assembly, the quality of the protective wall is independent of the deployed personnel. Installation in adverse conditions like limited sight, darkness, rain and wind is also possible without any efforts. 

We carry the following 3 standard systems variants for which we have obtained a static type test from LGA Bayreuth:

Flood Height	Number of dam beams	Dam beam dimensions	Name
550 mm	3	50 x 226	IBS-K50-550
900 mm	5	50 x 226	IBS-K50-900
1300 mm	7	50 x 226	IBS-K50-1300

Intermediate flood heights of 1100, 740, 370 and 190 can be realised by inserting less dam beams into the standardised K-trestles of the above system variants.

When using a nail plate on bitumen cover layers and roads, the three system do not require additional anchoring. This configuration was subjected to a principle check at LGA Nuremberg. The prerequisite is that the surface is capable of bearing surface pressures of 100, 200 or 400 kN/m².

We do recommend anchoring the system when using it on rough concrete surfaces and pavement to prevent slipping.

We provide an advanced storage technology for our system. This ensures contact-free storage of the dam beams and K-trestles through spacer blocks made of water-proof bonded wood. The system is stored in hot-galvanised steel palettes equipped with fork tracks, stackable palette feet and tension belts. Due to the contact-free storage of the individual parts on the steel palettes, these can be simply rinsed off with a water hose after use.

If the system cannot be stored in a suitable location, it can also be delivered and stored in containers. Depending on the flood height, protective walls with a maximum length from 130 to 280 m can be stored in a 12’ container.
