【Expansion Device】Ground Treatment of Expansion Devices - An Unexpected Pitfall!
The water resistance greatly varies depending on the ground cover! A detailed explanation of the shapes and types of ground cover!
In the construction work for the ground cover section that needs to be done at both ends of the expansion joint, aesthetics tend to be emphasized, but the treatment of the ground cover section of the expansion joint is also a part that prevents the deterioration and leakage of the bridge. Since it doesn't appear much in cost estimation, many people may not have been very aware of it until now. At Expansion Joint Navi, we will explain about expansion joints and ground cover treatment.

Company information
CRETEC, a company under Crittec Industries, was born from the combination of Create (creation) and Technology. As a comprehensive manufacturer of bridge expansion devices, we continue to develop expansion devices that contribute to the longevity of bridges and environmental protection. Moreover, we do not stop at product manufacturing; by consistently handling everything from research, design, manufacturing, sales, to construction in-house, we can manufacture and install expansion devices that meet the requests of our clients and general contractors, as well as the conditions and environments of the bridges and roads on-site. We also take into account the issues that arise during the installation of expansion devices and the damage conditions of existing devices that are removed, using this information to improve and develop our products. Please feel free to contact us for inquiries about bridge expansion devices, requests for materials, or estimates. ◆ What is a bridge expansion device? It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
