Strengthening & protective applications
Building strong foundations for the cities of tomorrow
In the early 1980s, Elkem was the first to supply the construction industry with a revolutionary range of silica fume products that significantly improve the performance, durability, and sustainability of construction materials.
We're committed to making buildings and infrastructure more durable
Silica fume for fiber cement
Enhancing cement microstructure and durability
Silica fume, also known as microsilica, is commonly used to enhance the durability of fiber cement, and as the manufacturers of the original microsilica product, we have over 40 years’ experience of helping customers.
Silica fume for concrete
Improving the performance and durability of concrete
The construction industry is always looking for ways to improve the durability and performance of concrete structures – and since the early 1980s, we’ve been producing a unique range of silica fume (microsilica) products that do exactly that.
Silica fume for gypsum board
Enhancing the heat- and fire-resistance of drywall
Gypsum board – also referred to as drywall, wallboard or plasterboard – is widely used for interior wall and ceiling coverings. The addition of silica fume (microsilica) overcomes the reduction of shrinkage that can occur on exposure to heat or fire.
Ferrosilicon for steel used in major infrastructure projects
Improving quality and performance of steels using ferrosilicon alloys
The performance of steels used in major infrastructure projects such as skyscrapers is placing ever-greater emphasis on the quality of ferrosilicon (FeSi) alloys used to make the steel – and that’s where our expertise comes into play.
Silicone release liners for roofing, building and construction liners
Release liners for protecting mastics, sealants and tars
A wide range of mastics, sealants and tars are used in the building & construction industry – and the use of silicone-based liners facilitates transport of these products to the building site and ensures consistent and stable release whatever the ambient conditions.
Silicon for aluminium alloying in construction materials
Enhancing the performance of aluminium with silicon alloying
The addition of silicon enhances the corrosion resistance, durability and tensile strength of aluminium, making it suitable for harsh environments and structural components. We supply a wide range of metallurgical silicon grades used for alloying, helping ensure the longevity and reliability of aluminium construction materials.
Silica fume for construction
Elkem provides a range of products for a variety of applications in both industrial and residential settings, from waterproofing and insulation to structural bonding and joint filling. Our products are designed to meet the highest standards of quality and performance, and we strive to provide the best possible customer service.
We provide solutions for eliminating water ingress
Silicone-waterproofed construction materials
Eliminating water ingress and damage with pretreated construction materials
The porosity of many construction materials makes them prone to water infiltration and damage – but this can be resolved by applying highly hydrophobic silicones. We supply a range of ready-to-use building materials that come pre-treated with high-performance silicones.
Ready-to-apply silicone-based coatings
Easy-to-apply coatings for in situ water protection
Many construction materials are prone to water infiltration and damage – but these problems can be solved by using hydrophobic silicone coatings in situ. We supply silicone treatments in a wide range of emulsions, dilutions and powders for convenient and effective pretreatment.
