How to Select an Injection Material to Seal Leaks?

Leaks in concrete, masonry and natural stone structures can often be securely sealed and waterproofed by injection. However, to make leaking structures watertight for the long term, it’s essential to select the right injection material. On the basis of our extensive technical and practical experience, we have prepared a guide which will help you choose the optimal injection solution for your project requirements.

Designing Colorful Floor in Hospitals and Other Healthcare Facilities

A well-crafted color palette can do wonders for a healthcare facility. The use of color and graphic images can align to the existing logo and symbolic color of the facility to achieve an overall visual aesthetic, while it can also elicit emotions and unique perceptions of space. It has an ability to calm or excite, can make a room appear smaller or more grandiose, or even trigger subconscious reactions. Color is the most vital, impactful and expressive design element in a designer’s toolbox.

The Science Behind Wood Floor Adhesives

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.

Sikafloor® MultiDur Water Based Epoxy Flooring

Smart use of water–based materials can be an effective strategy against moisture-related problems in floor constructions. This is what we implement in our Sikafloor® MultiDur water-based epoxy range. Tough and water vapor permeable, plus low VOC & odor, Sikafloor® MultiDur water-based epoxy flooring systems are especially suitable for your next functional floors if you have issues of humidity or rising moisture in the floor slab. Additionally, among the range, the system Sikafloor® MultiDur WS-26 has the unique performance of the fire classification A2fl -S1.

Performance Enhancer for Portland Limestone Cement (PLC)

The motives to replace clinker with supplementary cementitious materials (SCM) are well known. However, granulated blast furnace slag, natural pozzolanes, qualified fly ash and further SCM have a limited availability; the total potential replacement of the global clinker production is less than 30%. Limestone is increasingly being used as a component in Portland-Limestone cements: Sika offers an additive to enhance grinding and performance.

Addressing the Unwanted Impacts of Grinding Aids

Grinding aids and strength enhancers are well known for their ability to increase cement mill productivity, and the mechanical strength of mortar and concrete. However, little information is available on the potential drawbacks of their usage. To close the gap, Sika Services addresses the possible impacts on health and safety and the environment, and on cement properties in production and use.

Progress with Grinding Aids for Vertical Roller Mills

The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles.

Dry vs Wet Machine Applied Mortars for Concrete Repairs

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.

Sprayed Concrete

Successful sprayed concrete requires the combination of many aspects of modern concrete technology especially concrete admixture chemistry, together with modern materials handling technology. The increasing demands for cost-effectiveness and the protection of health and the environment mean that sprayed concrete has been in continuous development. Thanks to more than one hundred years of experience, expert knowledge and a focus on performance and economy, Sika is able to provide the newest generation of sprayed concrete solutions.

Screed Evaluation Methods

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.

Architectural Concrete

The ability to appreciate concrete as an aesthetically versatile construction material has led Sika to many innovations in architectural concrete. The flexibility of concrete in design enables the designer to create structures not possible with other construction materials. Combining this flexibility with Sika’s over one hundred years of experience and expertise in concrete formulation and optimization allows structures of true architectural value to be realized.

3D Concrete Printing

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.

Considerations for Facade Joint Design

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.
