Cementitious 3D construction printing (3DCP) or 3D concrete printing is a form of additive manufacturing used to fabricate buildings or construction components in completely new shapes not previously possible with traditional concrete formwork.

The task of wood floor adhesives is to firmly bond the organic wood floor elements to the generally inorganic screed. The adhesive must hold the wood in place, connect it to the underlying screed and transfer stress originating from the natural expansion and contraction of the wood to the generally rigid screed. The undesired but natural movement of the wood can become visible in cupping, joint formation, or in extreme situations failure of the adhesive or screed.

If the screed is even, strong and dry enough, then only mechanical surface preparation such as grinding and cleaning is required, before wood floor bonding is possible. However there are many situations where the existing or even new screeds are not suitable, and additional treatment is necessary before wood flooring can be installed. Sika has developed complete balanced system solutions for all of the different possibilities that may be found in these situations.

A functional and purpose-built floor is key to a safe and hygienic production environment in food and beverage facilities. Floors that are hygienic, non-slip, easy to clean, and durable provide a safe and attractive place to work. Choosing and installing the right floor are critical to every work environment. This article looks at getting it right the first time — achieving satisfactory and long-term flooring in a food processing environment.

A prerequisite for a sustainable and beautiful wood floor is a strong and dry screed. Therefore this screed has to be carefully accessed. The first source of information is the architect, engineer, or main contractor who will have all of the information about the build-up and nature of the floor. The second source is the screed contractor who can provide the screed details and if appropriate, any subfloor heating protocols. If, as so often in renovation projects most of this information is not available, there are a few simple methods that can be used to evaluate the screed.

The facade is the face of buildings. In contemporary architecture, the facade is of special interest expressed by large dimensions, unconventional shapes and high material diversity. Especially with these unique shapes and connections, joint design is demanding and prone to mistakes. For integral joint specification, following some rough guidelines will result in a long-lasting and tight building envelope.

Concrete repairs can be conducted with different systems and methods. In the European Standard EN 1504 Part 9, Principle 3 defines the application of repair mortars by machine as well as by hand. In this article you will learn about the advantages of machine application for both dry and wet spray processes. We also give an overview of how to select the right method and equipment for each type of application together with the corresponding Sika materials.
