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.
Elastic Joint Sealing
Strong and durable adhesion of the sealant to the substrate is the essence of joint sealing, no adhesion means water ingress.
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.
Chemical anchors are used in a wide range of structural and non-structural applications. These anchoring jobs may also be needed in the concrete wind turbines to fix ancillary elements inside the turbine. Sika has a wide range of chemical anchors that combined with the calculation software will support all needs in the wind business.
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. In some cases, concrete deterioration lead to crack formation. For these cases, Sika has the complete portfolio of injection products that will solve the problem.
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®.
