Building and construction

From high in the sky to under the ground, Ramsauer’s professional and construction-grade materials can withstand the toughest conditions.

Whether high in the sky or underground – at Ramsauer, we’re all about bonds

In building and construction work, it’s all about using materials that do what they are supposed to and are made to last. In tunnels, bridges or industrial buildings, even the smallest inadequacies can lead to huge damage with long-term ramifications. That’s why sealants used in these areas must be able to reliably withstand heavy stress and strain such as extreme temperatures, chemical substances and moisture. Stringent standards are also in place to ensure lasting bonds.

Resilient construction sealants

Especially in larger building works, expansion joints between the individual elements ensure that tension is balanced out, preventing cracks or damage. These joints usually have extra-wide cross-sections so require a large amount of material in a short space of time. To help the joint accommodate the movements of the individual building parts, the best choice is the most elastic sealant possible. In both structural and civil engineering projects, materials often have to contend with unclean ground and high levels of strain from environmental and weather conditions. To meet these challenges, there are special sealants that have been developed to withstand the stresses on construction sites long-term.

  • The materials used have to be able to withstand chemicals.
  • If products are compatible with a wide range of materials, this unlocks a wide range of applications.
  • The sealants must meet all the applicable standards.
  • If they are easy to smooth, this ensures ideal results.

Stronger than even fire

Perfect fire safety requires the right construction materials to be used in each and every area. Joints are created in places where different components abut – and these must be sealed using sealants specially developed for fire safety. Reliable protection is only offered by approved and certified fire-safe products. These must be compatible with a variety of surfaces and be capable of withstanding heat. For this to be done successfully, highly precise work is essential.

  • Construction materials need to be flame-retardant.
  • Check to make sure your product is compatible with other materials.
  • The products should be easy to apply.
  • Only use tested materials.

Insulated walls throughout buildings

Cavities in indoor walls and openings in outdoor walls can be found on every building site. As well as maintaining walls’ acoustic and thermal insulation properties, polyurethane foam also keeps moisture out of the space in question – the foaming process completely fills the cavity. Since the polyurethane foam swells after foaming, it is important to ensure the correct dosage when using it. Too much foam can cause damage. Ramsauer has developed an innovative valve for this purpose, which makes filling wall openings drastically simpler.  

  • It is easier to work with polyurethane foams when they can be dispensed effectively.
  • A safety valve allows for a clean foaming process.
  • Ensure that the product has the correct foam structure.
To ensure that polyurethane foam insulates reliably and has a durable hold, the substrate should be as clean as possible. You can find out more about how to properly apply polyurethane foams in our how-to article. View article

04  Bonding concrete anchors

For an extra dose of stability

Wherever anchors or rebar are used in concrete – for instance, in bridges, high-rises or tunnels – the adhesives used must meet special criteria. These adhesives are subjected to extreme mechanical forces over a lengthy period of time. At the same time, safety and stability must be ensured long-term. Naturally, strict standards also apply to all construction materials used here.

  • A short curing time makes the adhesives easier to apply.
  • The products must be able to cope with significant swings in temperature.
  • The products must perform extremely well in pull-out testing.
