The Kinematic chain system is a building technology which creates an elastic connection between the decks both longitudinally and transversally thus ensuring a "hinge" behaviour against flexural stresses in the connection area. This system allows all the longitudinal deformations of the deck resulting from shrinkage, creep or temperature changes, to focus on one point, usually the centreline of the engineering structure or by one of the abutments. The Kinematic chain system thus allows to exploit all the advantages offered by continuous structures (seismic behaviour, reduction in the number of joints without giving up those offered by the statically determinate structures consisting of simple beams, design and construction simplicity). It is suitable both for new and existing engineering structures, especially when their seismic adjustment is necessary. It allows to manage longitudinal seismic stresses transferred to the bridge deck/piers interface.

Penstocks are used to discharge the headwater from a reservoir. Due to thermal and dynamic effects on the pipelines which are usually run underground in the mountain, compensation for expansion is necessary. By fitting an expansion joint, slow creep movements, eccentricity, dilation and also pipe misalignment can be reliably absorbed. The MANOY® system seal WP, type 436, was specially developed for leakagefree operation of an expansion joint.

Expansion joints serve a crucial role in industrial ductwork by facilitating the controlled expansion and contraction of ducts. Their primary function is to accommodate thermal movements within the ductwork system. They mitigate thermally induced stresses by allowing thermal movements in a relatively unrestricted manner. Expansion joints contribute to the overall flexibility and structural integrity of the system which is essential in preventing the build-up of stress that could otherwise lead to damage in equipment, ductwork, and supporting structures.

Bitumer Flexigum PU is a one-component bitumen-polyurethane compound that forms a permanently flexible and chemically resistant fastening and stress transfer compound. Bitumer Flexigum PU finds its use in: •for continuous resilient fixing of the rail as a subfloor, •rail fastening compound and as a lagging for the underfloor, •for making permanent and flexible expansion joints between concrete slabs and elements made of steel, •filling the gaps located between the road strip and the rail, •for filling concrete-to-concrete joints •filling joints, gaps, cracks and expansion joints in heavily worked asphalt and concrete pavements ( e.g., curbs on bridges), •filling joints "working" on steel and concrete bridges and other pavements characterized by strong movements.
