What are the most common mistakes in executing construction joints?

Placing the joint in an inappropriate location. Ignoring reinforcement of the joint. Using unsuitable materials. Failing to adhere to the specified dimensions. Not inspecting after execution.

What Are the Requirements of the Egyptian Code Regarding Expansion Joints?

The Egyptian Code for Expansion Joints requires the installation of expansion joints in buildings, roads, and bridges to protect structures from cracks caused by thermal expansion and contraction or excessive loads. The main requirements include: Spacing between expansion joints : Expansion joints must be installed every 20–30 meters in concrete structures to ensure flexibility. Types of expansion joints : Horizontal, vertical, and structural joints depending on the project type (buildings – bridges – tunnels – roads). Expansion joint filler materials : Must be flexible, resistant to moisture and weather conditions, and provide continuous waterproofing. Execution of expansion joints : Strict compliance with engineering designs and precise implementation to avoid future problems. Technical supervision : Relying on specialized companies such as iChem Egypt to provide high-quality solutions fully compliant with the Egyptian Code and international standards. To learn more:

Custom Expansion Joints Design – iChem

Yes! At iChem, we offer the ability to design and manufacture fully custom expansion joints tailored to the specific needs of each project. We consider movement type, expected loads, and surface conditions. With over 10 years of experience, we are your trusted partner for safe and effective solutions for your projects.

The Importance of Custom Expansion Joints

Expansion joints are essential for protecting buildings from cracks caused by natural concrete movement. Custom-designed joints provide:

Long-lasting performance for floors and walls.
Ability to withstand various loads according to project requirements.
Flexibility in installation on all types of surfaces.
Compliance with technical specifications and precise measurements for each site.

Using these joints ensures project safety and reduces future maintenance costs.

How iChem Designs Custom Expansion Joints

1. Movement Analysis

We determine whether the movement is horizontal, vertical, or combined to select the most suitable expansion joint.

2. Load and Spacing Study

We calculate the expected loads and optimal spacing between joints to properly distribute forces and protect the structure.

3. Material Selection

We use high-quality materials resistant to corrosion, pressure, and environmental factors to ensure durability and long life.

4. Surface and Measurement Considerations

Joints are designed to fit floors and walls, taking precise site measurements into account.

5. Installation Engineering Details

We provide detailed installation plans in collaboration with consultants and contractors to ensure flawless execution.
