TheStrip Seal Expansion Jointsystem is a unique concept for effectively sealing expansion joints in bridges and structures with movements up to 125 mm. Single-Seal Expansion Joints are available in different versions for constructive systems exposed to traffic. In all types of constructive systems there is clear distinction between the two main functions "inflexible anchoring" and "watertight connection“. This allows for best possible adjustment of the two components sealing profile and edge construction to the conditions of the traffic road.
Strip Seal Expansion Joint Key Features:
Strip Seal Expansion Joint Description :
The Bridge deck expansion joints is an important element in the functioning of bridge structures. When joints fail to fnction properly they can create problem out of proprtion to their size. Selection of a good joints for use can create fewer bridge maintenance problems there for Indian Ministery of Roads Transport & Highways (MORT& H ) has setup certain guidelines for the Design, Manufacture and Installation of Strip Seal Expansion Joint in India.
Types Of Strip Seal Expansion Jointwe Design, Manufacture, Supply, Replace, Supervision & Installation
COMPRESSION SEAL JOINT:
is used for smaller range movements from 0 to 40mm. It consist of two angles with an elastomeric seal. The seal is installed in compressed position This Joint is ideal for replacement of old joint and for new project.
Strip Seal Expansion Joint :
Strip Seal Expansion Joint is used for medium movement from 0 to 80mm. It consists of two edge profiles with an elastomeric seal in between. The edge profiles are generally cast into a noising of the structure. These Strip Seal Expansion Joint are expected performance life more than twenty five years. This is most popular and expected joint system among Bridge Consultants and Engineers worldwide.

A slab seal expansion joint, also known as a bridge expansion joint or simply an expansion joint, is a structural element used to allow movement and absorb stresses in large concrete structures, such as bridges, highways, parking garages, and other infrastructure. Concrete structures are subject to temperature variations, moisture changes, and dynamic loads, which can cause them to expand, contract, or shift over time. To accommodate these movements and prevent damage, expansion joints are strategically placed at specific intervals along the length of the structure.
The purpose of slab seal expansion joints is to create a gap between adjacent concrete slabs, which allows for movement without causing cracks or damage to the structure. These joints are typically filled with flexible materials or seals to prevent debris, water, and other harmful substances from penetrating the gap and potentially causing corrosion or deterioration.
The most common types of slab seal expansion joints include:
1. Strip Seal Joints: These consist of a metal strip that spans the gap between the concrete slabs. The strip is usually bolted or fixed to one side of the joint and has a compressible rubber or neoprene insert that fills the gap.
2. Modular Joints: Modular joints are pre-fabricated units that cover the gap between the slabs. They are easy to install and provide a watertight seal.
3. Finger Joints: Finger joints are made up of multiple steel fingers or bars that interlock to accommodate movement. These joints are commonly used in large structures with high movement requirements.
4. Elastomeric Joints: Elastomeric seals are made from high-quality rubber or elastomeric materials that can compress and expand to accommodate movement while maintaining a watertight seal.
Slab seal expansion joints play a critical role in maintaining the longevity and safety of concrete structures by reducing the stresses and preventing the development of cracks that could compromise the integrity of the infrastructure. Proper design, installation, and maintenance of these expansion joints are essential to ensure their effectiveness and longevity.
