Challenges

During the construction of a major Battery Energy Storage System (BESS) project in Chinchilla, Queensland, the installation team faced significant challenges in supporting extremely heavy prefabricated battery units. Each unit weighed between 12 and 30 tonnes and was positioned on concrete strip footings.

Key challenges included:

• Providing sufficient compression to act as a bearing cushion under very high static loads.
• Preventing permanent deformation over the long service life of the installation.
• Ensuring secure bonding to concrete footings to maintain alignment during placement.
• Withstanding outdoor environmental exposure, including temperature fluctuations from -5°C to +40°C.
• Meeting tight construction and installation timelines without delays.

Solution

To address these challenges, Natural 60 HG Rubber Bearing Strips manufactured by Forech were supplied through our trusted channel partner Reglin Rubber (Australia).

The solution offered the following advantages:

• High load-bearing capacity with predictable compression characteristics.
• Excellent resistance to permanent deformation under sustained heavy loads.
• High tensile strength and tear resistance for long-term durability.
• Consistent performance across a wide temperature range in outdoor environments.
• CN bonding layer to ensure strong adhesion to concrete foundations.

The bearing strips were custom-cut to 12 mm thickness and 150 mm width, supplied as longitudinal strips and bonded directly to the concrete strip footings prior to battery placement.

Outcome

Following installation, the project team observed the following outcomes:

• Successful installation of rubber bearing strips across all concrete footings.
• The material withstood high applied loads without over-compression.
• Battery units were positioned accurately with stable long-term support.
• Installation proceeded on schedule, supporting timely project completion.
• Reduced risk of structural stress transfer and improved system reliability.

Conclusion

By selecting Forech-manufactured Natural 60 HG Rubber bearing strips, supplied via Reglin Rubber (Australia), the battery energy storage project achieved a reliable, durable, and engineered foundation solution. This case study demonstrates the critical role of high- quality rubber components in supporting heavy-load infrastructure applications, ensuring long-term performance in demanding outdoor environments.
