Interbloc structures, like many precast concrete systems, have an inherent durability that translates into a low-maintenance construction solution. While the system is designed to stand the test of time, there are some aspects that require attention over its lifespan. This guide provides key insights into maintaining the longevity and functionality of your Interbloc structure.
Interbloc incorporates lifting anchors with a factor of safety exceeding five, aligning with Worksafe NZ's recommendations for multiple lift precast concrete elements. When lifting blocks that have been in place for an extended period ensure you check the integrity of the anchor. Evaluate the the anchors by looking for signs of damage and corrosion. In cases where anchors show signs of wear, consider utilising Envirocon's gravity lifter for safe and efficient block reuse.
Over the life of a structure, blocks may incur damage, often resulting from machinery interaction with the wall. In such instances, the affected section of the wall can be easily dismantled, allowing for the swift replacement of damaged blocks before reconstructing the structure. This proactive approach ensures the ongoing integrity and aesthetics of the Interbloc system.
For walls incorporating vertical reinforcement using Envirocon's 'fixing kits,' a tightening schedule is crucial. One month after block installation, tighten the fixing kits to compensate for any settlement in the blocks. The tension on the rods is vital to their role in reinforcing the wall. Subsequently, conduct regular checks and tighten the fixing kits every 12 months or as needed to uphold the structural integrity of the wall.
Structural engineers may impose operational restrictions on the Interbloc wall, such as limitations on the maximum height for material storage against the wall. These restrictions are outlined in the original design documentation. It is imperative that the structure owner ensures that all personnel are familiar with and adhere to these operational restrictions. Regularly communicating and reinforcing these guidelines contribute to the long-term stability and safety of the Interbloc structure.
By proactively addressing these maintenance considerations, you can extend the life of your Interbloc structure and ensure its continued reliability and safety. Regular inspections and adherence to recommended maintenance practices will contribute to the sustained performance of your construction investment.
