What is Strip Seal Expansion joint in concrete? Purpose of a Strip Seal Expansion Joint in concrete. Where to use Strip Seal Expansion Joint. Procedure to make a Strip Seal Expansion joint step by step.
A strip seal expansion joint in concrete is a type of joint used to allow for movement in the concrete due to temperature changes or ground movement. It is a mechanical joint made up of two steel edge rails and a replaceable rubber sealing element. The steel edge rails are anchored to the concrete on either side of the joint, and the rubber sealing element is inserted between the two edge rails to create a watertight seal.
The purpose of a strip seal expansion joint in concrete is to prevent damage and deterioration of the concrete caused by temperature changes or ground movement. The joint allows the concrete to expand and contract without causing damage and provides a watertight seal to prevent water from entering the joint and causing further damage. Strip seal expansion joints are commonly used in bridges, parking structures, and other large concrete structures.
To create a strip seal expansion joint in concrete, follow these steps:
- Determine the location and size of the joint: The location and size of the joint will depend on a variety of factors, including the expected movement in the concrete and the type of traffic that will be using the surface.
- Prepare the concrete: Clean and prepare the concrete surface where the joint will be installed.
- Install the edge rails: Anchor the edge rails to the concrete on either side of the joint opening.
- Install the rubber sealing element: Insert the rubber sealing element between the two edge rails. Make sure the rubber element is properly aligned and extends beyond the edge rails.
- Secure the sealing element: Use the locking system provided by the manufacturer to secure the sealing element in place.
- Finish the joint: Use a finishing tool, such as a trowel, to smooth and finish the joint.
- Clean up the joint: Use a broom or compressed air to remove any debris from the joint.
By following these steps, you can create a strip seal expansion joint that will allow for movement in the concrete without causing damage or cracking. It is important to follow the manufacturer’s instructions for installation and to choose the right size and type of joint for the specific application to ensure that it can accommodate the expected movement in the concrete.
