As infrastructure continues to age, asset owners are increasingly rethinking the rebuild. They are exploring how repair and proactive maintenance can maintain and extend the life of existing structures. This is particularly relevant in the water industry. AMP8 places greater focus on maintaining and improving existing assets alongside investment in new infrastructure. While demolition and replacement will sometimes prove necessary, rehabilitation can provide a practical alternative when an existing structure remains suitable for continued use.
A proactive maintenance approach means identifying deterioration early. It also means carrying out appropriate repairs before problems become more significant. During AMP8, the water industry is placing greater emphasis on maintenance, asset resilience and long-term performance. Early intervention can help keep existing infrastructure operational for longer. It can also extend asset service life, reduce further deterioration and minimise the need for major intervention or replacement.
When considering the environmental impact of infrastructure maintenance, it is important to look beyond the repair itself. Demolishing an existing structure and replacing it often requires teams to remove and dispose of existing materials, transport materials, manufacture new products and carry out additional construction work. These activities generate significant waste and consume energy, contributing to carbon emissions.
Proactive maintenance and timely repair can help asset owners avoid this cycle. By maintaining existing structures and addressing deterioration as it occurs, asset owners can extend service life and reduce demolition and new construction. In many cases, repairing and strengthening an existing structure also makes better use of the materials and resources already available.
A more sustainable approach to infrastructure considers the whole life cycle of a structure. Early maintenance can reduce waste, limit the need for new materials and minimise the environmental impact of construction. It can also help existing structures remain safe, functional and in service for longer.
One of the water industry’s most significant challenges is hidden in plain sight, the ageing concrete infrastructure that plays a vital role in keeping essential services operating. Much of this infrastructure continues to perform its function, but gradual deterioration can go unnoticed until more extensive damage occurs.
This creates the opportunity for proactive mainenence, by identifying these defects early and carrying out effective maintenence through repairs, asset owners can extend the service life of existing structures by avoiding unnecessary demolition and replacement.
Issues are not always as visible as we think. However, the opportunity for proactive maintenance is clear. Through regular audits and asset evaluations, deterioration can be identified early. Effective maintenance can help extend asset life and reduce the need for major repairs or replacement.
Natural Cement can be used for the repair and rehabilitation of concrete structures across a range of applications. Used as part of an appropriate maintenance and repair strategy, it can help restore existing concrete and extend the service life of suitable structures.
This approach is particularly relevant where an asset remains fundamentally sound but is showing signs of deterioration. Rather than waiting until significant damage has occurred, early intervention can help keep the structure performing for longer.
For example, at Margate Wastewater Treatment Works, severely deteriorated concrete was repaired using SHOTCRETE 513, following the removal of contaminated concrete and repair of heavily corroded reinforcement. Meanwhile, repairs to a primary settlement tank were carried out using NATCEM® 35, which was used to repair and re-render the tank walls, significantly extending the asset’s service life and eliminating the need for immediate replacement.
Of course, not every structure will be suitable for repair, and decisions should always be based on the condition of the asset, its intended service life and the requirements of the project. However, where repair is appropriate, proactive maintenance can be an important part of reducing the need for demolition and replacement.
