Hablex glue, also sometimes spelled Hebel glue, is a type of adhesive specifically designed for bonding Hebel blocks together during construction. Here’s a breakdown of its key features and uses
It is a dry chemical compound that is mixed with water and creates a sticky, paste-like substance, which is now called block glue. Due to its unique composition, this material can create a very strong connection between the blocks, and for this reason, experts recommend using it for the Chinese wall. Of course, we must mention that this category of materials is more suitable for autoclaved light blocks and they cannot be used for any type of block. The structure of these adhesives is such that it can make a connection 4 times stronger than cement. to create On the other hand, its final weight is very small and can greatly reduce the dead load of the building. Another unique advantage of these adhesives is moisture resistance. In fact, this group of adhesives can increase the overall resistance of the wall against moisture. Of course, these are only a few of the unique advantages of block glue
Hebel blocks, also known as autoclaved aerated concrete (AAC) blocks, are lightweight yet strong building blocks commonly used for interior and exterior walls. They are made from a mixture of sand, cement, fly ash, and a foaming agent, resulting in a porous structure with good insulation properties.
Unlike traditional concrete blocks that rely on mortar for bonding, Hebel blocks require a special adhesive like Hablex glue. This glue offers several advantages:
Strong Bond: Hablex glue is formulated to create a strong and secure bond between Hebel blocks, ensuring a sturdy and reliable wall structure.
Faster Setting Time: Compared to mortar, Hablex glue typically sets much faster, allowing for quicker construction progress.
Ease of Use: Hablex glue is often pre-mixed or requires minimal mixing, making it easier to apply compared to traditional mortar mixes.
Thinner Application: Hablex glue can be applied in a thinner layer than mortar, reducing material usage and potentially contributing to a more level wall surface.
Improved Thermal Performance: The thin glue layer can minimize thermal bridging, potentially enhancing the overall thermal insulation properties of the Hebel block wall.
The application process for Hablex glue typically involves these steps:
Surface Preparation: Ensure the Hebel block surfaces are clean, dry, and free from dust or debris.
Mixing (if required): Some Hablex glue formulations might be pre-mixed, while others require mixing according to the manufacturer’s instructions.
Apply the Glue: Using a trowel or a notched spreader, apply a thin layer of Hablex glue to the edge of one Hebel block.
Place the Block: Carefully position the next Hebel block onto the glued surface and press it firmly to ensure proper adhesion.
Repeat: Continue applying glue and placing Hebel blocks in a sequential manner to build the wall.
Additional Considerations:
Choose the right Hablex glue: Different Hablex glue types might be available, each with varying properties like water resistance or setting time. Select the one suitable for your specific project requirements and climate.
Follow manufacturer’s instructions: Always refer to the manufacturer’s recommendations for mixing ratios, application techniques, and drying times for optimal results.
Consult a professional: For complex projects or if you’re unfamiliar with Hebel block construction, consider consulting a qualified mason or construction professional for guidance.
By understanding the purpose and features of Hablex glue, you can appreciate its role in constructing strong, efficient, and thermally sound walls using Hebel blocks.

Strong Bond: Hablex glue is specifically formulated to create a strong and secure bond between Hebel blocks. This ensures a sturdy and reliable wall structure that can withstand normal loads and stresses.
Faster Setting Time: Compared to traditional mortar, Hablex glue sets much faster. This allows for quicker construction progress, reducing overall project timelines.
Ease of Use: Hablex glue is often pre-mixed or requires minimal mixing compared to traditional mortar mixes. This makes it easier and less time-consuming to apply, especially for DIY projects.
Thinner Application: Hablex glue can be applied in a thinner layer than mortar. This reduces material usage, lowers costs, and can potentially contribute to a more level wall surface due to less variation in thickness between blocks.
Improved Thermal Performance: The thin layer of Hablex glue minimizes thermal bridging compared to thicker mortar layers. This can enhance the overall thermal insulation properties of the Hebel block wall, contributing to better energy efficiency.
Cleaner Application: Hablex glue is generally less messy to work with compared to mortar. This can be advantageous for indoor construction projects where dust control is important.
Cost: Hablex glue can be more expensive per unit volume compared to traditional mortar. However, considering the benefits like faster setting time, thinner application, and potentially less material waste, the overall project cost might be comparable.
Skill Level: While generally easier to use than mortar, applying Hablex glue still requires proper technique and attention to detail to achieve optimal bonding and a level wall surface. For complex projects, a skilled mason might be recommended.
Limited Applications: Hablex glue is specifically designed for Hebel blocks and might not be suitable for bonding other construction materials like bricks or stones.
Storage and Shelf Life: Hablex glue might have a shorter shelf life compared to traditional mortar mixes. It’s important to check the expiration date and use it within the recommended timeframe for best results.
Weather Limitations: Some Hablex glue formulations might have limitations regarding extreme temperatures or weather conditions during application. Following the manufacturer’s recommendations for suitable weather conditions is crucial.
Hablex glue offers a valuable solution for constructing walls using Hebel blocks. Understanding its advantages and disadvantages can help you determine if it’s the right choice for your project. For large or complex projects, traditional mortar might be a more cost-effective option. However, for smaller projects, faster construction times, or improved thermal performance goals, Hablex glue can be a suitable and user-friendly alternative. Always consult the manufacturer’s instructions and consider your specific needs and skill level before using Hablex glue for your Hebel block construction project.
