• iChem provides flexible joint filling materials such as silicone and polyurethane, which are essential for the effective implementation of contraction joints.

• iChem offers comprehensive concrete joint solutions, including design, supply, and technical support, especially for industrial projects, roads, and flooring.

• iChem products help preserve the service life of concrete and reduce cracks caused by shrinkage.

Floor expansion joints

In floor expansion joints, gaps are left between floors to allow them to expand and contract as a result of temperature changes and to prevent cracks.

Features of floor expansion joints

1. iChem floor expansion joints provide flexibility to the floor because they allow it to expand and contract in a natural movement without damage.

2. iChem floor joints give a flat and homogeneous surface to the floor.

3. Floor expansion joints are filled with flexible materials such as rubber and silicone.

4. The main movement in the floors is horizontal.

5. iChem floor expansion joints are installed in large spaces such as parking lots and industrial buildings.

Wall expansion joints

In wall expansion joints, gaps are left between the walls to allow the walls to move naturally as a result of temperature changes and to prevent cracks.

Features of wall expansion joints

1. iChem wall expansion joints allow walls to move flexibly without cracking.

2. Reduce the impact of large cracks and fissures on the building structure.

3. iChem wall joints improve the performance of walls and maintain their shape, especially in large buildings.

4. Wall expansion joints are filled with flexible materials such as sealant to prevent water or air leakage.

5. Movement in walls is horizontal and vertical.

6. Wall expansion joints are used in tall buildings and places exposed to large temperature changes such as exterior facades.

To install expansion joints, basic points must be considered to ensure their high efficiency and achieve the main purpose, which is to protect buildings from cracks resulting from thermal expansion and contraction. We summarize these points in the following steps:

1. Planning and study:

• Study the project drawings and designs to choose the appropriate types of joints, determine their locations, and pass tasks to the work team. • Prepare a timeline that matches the work stages and ensure commitment to the specified time.

2. Choosing expansion joints:

• Knowing the amount of pressure and stress that the structure will be exposed to and the type of environmental factors surrounding it to choose materials that can bear the loads on them.

• Choose expansion joints that are consistent with the shape of the designs and finishes on the project

3. Surface preparation:

• Clean the surface of dust and gravel and ensure that there are no chemicals or oils to ensure the joints are fixed. The surface must also be free of protrusions.

• Placemarks to determine the locations of the joints and review the engineering designs before installation to ensure the accuracy of the marks.

4. Section Installation:

• Cut the expansion joints to the lengths specified in the drawings and place them in their places, fixing them with adhesives or nails depending on the type of joints.

• Fill the joints with suitable fillers and ensure that there are no gaps to ensure flexibility of expansion and contraction.

5. Finishing:

• Level the surfaces using appropriate tools and leave the materials to dry according to the manufacturing recommendations.

6. Final cleaning:

• Remove any remaining filling materials, clean dust, and small parts, and dry the surfaces using an air dryer to prevent dust from accumulating due to moisture.

Expansion joints are construction joints that allow buildings to move naturally due to environmental changes to protect them from damage. They have many benefits, including:

1-Preventing cracks: Allowing buildings to move in all directions due to thermal expansion and contraction to prevent cracks in buildings.
2-Reducing pressure and absorbing vibrations: Expansion joints absorb vibrations and pressures resulting from earthquake movement and dynamic loads on structures.
3-Increasing structural efficiency: Contributing to enhancing the efficiency of structural buildings by making them safe, stable and durable to withstand all different environmental factors.
4-Improving insulation: Joints insulate heat, and fire and water retention properties can be added to ensure safety and security in buildings.
5-Design flexibility: Various forms of expansion joints are available to suit all projects and different finishes.
6-Easy to install and maintain: Joints can be easily installed and fixed, which facilitates maintenance work in the event of damage.
7-Economic cost: Expansion joints are considered an economical solution in construction projects because they protect the building from damage and cracks, which reduces the need for frequent maintenance and increases the building’s expected life.
