The concrete used in erecting wind turbines must be of a particularly high quality. The precast tower elements are assembled on site and must provide a long term tight structure. Thanks to Sika’s 100 years of experience and success, you can rely on our solutions.

Concrete Towers - Solid and High Quality Solution

Concrete is widely used in construction due to its properties of strength, durability and versatility. And this is transfer to the wind business. Therefore, the products used to bond or link the precast concrete elements must share the same properties. For this use, Sika has developed the special range of cementitious grout SikaGrout® and Sikadur® that fill the joints and transfer the loads, or even protect the reinforcement steel and bolts against corrosion

Sika is the unique supplier that can provide the needed grouts, protective systems, elastic sealants, structural adhesives or even chemical anchoring products for your project, avoiding quality or incompatibility problems.

With the complete solution, Sika is the perfect partner for the concrete tower wind business.

Parts of a Steel Tower

Elastic Joint Sealing

Strong and durable adhesion of the sealant to the substrate is the essence of joint sealing, no adhesion means water ingress

Structural Bonding

Element bonding adhesives provide a rigid bond between elements to transfer load. Sikadur® epoxy adhesives have already been used for decades effectively to bond precast concrete elements together and provide a waterproof seal.

Surface Protection of Concrete

Sika has developed and produced protection systems  (coatings or invisible protection) that are used all around the world to protect concrete surfaces and structures for many decades. This includes the protection of all types of buildings and structures, in various types of environment and climatic conditions. Find various

- protective coatings systems and- Hydrophobic impregnations help to increase the durability of concrete structures by reducing the water uptake behavior and preventing the ingress of water-dissolved contaminants such as chlorides. The aesthetic appearance of the concrete surface will not be changed.

Anchoring

Chemical Anchors are used in a wide range of structural and non-structural applications. They can be found in different grades of concrete, different masonries, and other substrates. Threaded rods as well as rebars and other fixing system can be installed with chemical anchors.

Concrete Repair and Reprofiling

Deterioration of concrete may happen due to corrosion, structural damage, water infiltration, freeze and thaw cycles, seismic activity, reactive aggregates etc. Years of research plus decades of practical experience have enabled Sika to develop a fully comprehensive solution which includes bonding primer and corrosion protection and repair mortars to restore and rehabilitate concrete structures.

Grouting to fill Voids

Concrete wind towers are generally built from precast concrete elements. Between two elements, the joint or gap needs to be filled with a product capable of transferring the loads besides of protecting the connection steel parts from corrosion. For this use, Sika has developed a specific proven range of products within the range SikaGrout®.
