The Advantages of Sika® Combiflex® and Sikadur®-31 DW for Expansion Joints

Understanding Expansion Joints

Expansion joints are crucial in construction, allowing structures to absorb movement caused by thermal expansion, contraction, and other dynamic forces. Without them, buildings and infrastructure could suffer from severe stress, leading to cracks and structural failures.

Effective expansion joint solutions are essential for maintaining the longevity and integrity of structures. This is where products like Sika® Combiflex® and Sikadur®-31 DW come into play, providing reliable and durable solutions.

What is Sika® Combiflex®?

Sika® Combiflex® is a high-performance joint sealing system designed to provide excellent adhesion and flexibility. It is particularly useful for sealing joints in areas exposed to water and other environmental elements. This system is renowned for its ability to accommodate significant movements and irregular joint shapes, ensuring a watertight seal.

The versatility of Sika® Combiflex® makes it suitable for various applications, from tunnels and bridges to basements and water tanks. Its durable nature ensures that structures remain secure and protected over time.

The Role of Sikadur®-31 DW

Sikadur®-31 DW is an epoxy adhesive used in conjunction with Sika® Combiflex®. This two-component adhesive enhances the system’s effectiveness by providing a strong bond between surfaces, ensuring that the sealing system remains intact even under challenging conditions.

One of the standout features of Sikadur®-31 DW is its resistance to water and chemicals. This makes it ideal for use in environments where exposure to harsh elements is a concern, such as chemical plants and water treatment facilities.
