New Zealand's Waterproofing Experts, Nuralite and Neuchatel have partnered with the expansion joint market leaders - Watson Bowman Acme.

For more than 50 years WBA has developed and manufactured expansion joints for some of the world’s most unique and complex projects.

With their combined skills they offer the complete waterproofing solution service.

Expansion joints are devices that are used to allow for the heat-induced expansion and reduction that takes place in various states of weather. Expansion joints are usually placed at strategic points in the construction, making it possible for the sections to expand and contract slightly without weakening the overall structure.

An expansion joint is an important part of the building design.

Expansion joints allow buildings to expand and contract without undue stress. The combination of the materials used, the building design, material compatibility and the use of the building influence the appropriate expansion joint.

The range also includes seismic joints which can accommodate significant structural movement.
When specifying the designer must consider:

• Have water draining away from the expansion joint
• Run the joint in straight lines where possible. This maximizes the use of continuous membrane in the joint
• Think if cars, wheel chairs or pedestrians will be moving over the joint
• Ensure the joint has enough movement capacity to accommodate the anticipated movement in the building
