Building repairs after extreme weather events

Extreme weather events, such as DANA (Isolated High-Level Depression), are becoming more common due to climate change, directly impacting building integrity. 

At Molins Construction Solutions, we offer specialised solutions to address the structural damage these events cause.

Impact of extreme weather events on buildings 

Heavy rainfall and strong winds associated with events like DANAs can cause various types of damage to structures, compromising their safety and functionality.

Most common structural damages

• Cracks and fissures in walls and roofs: Thermal changes and water from cyclones can cause cracks, affecting structural stability.
• Leaks and water damage: Water infiltration can deteriorate materials and promote mould, compromising building health.
• Loss of integrity in roofs and facades: Exposed parts like roofs and facades are often damaged, affecting both appearance and protection.

Technical assessment after an extreme weather event

Initial inspection to identify damage

A thorough assessment is essential to determine the extent of the damage and plan necessary repairs.

Use of technological tools for precise evaluation

The implementation of advanced technologies allows for the detection of damage not visible to the naked eye, ensuring appropriate intervention.

Structural damage repair in buildings

Reinforcement and repair of foundations

We use high-resistance mortars to restore foundation integrity after ground movement, settlement, or moisture damage. These solutions restore load-bearing capacity, extend the structure’s lifespan, and prevent future failures.

Repair techniques for walls and pillars

Systems such as structural repair mortars and carbon fibre reinforcements are used to repair walls and pillars affected by cracks, flaking, or loss of section due to impacts, corrosion, or excessive stress. These techniques ensure aesthetic restoration, functionality, and durability of the repaired elements.

Solutions for damaged roofs and covers

In the rehabilitation of deteriorated roofs and coverings, we integrate advanced waterproofing systems, such as polyurethane liquid membranes like PROPAM® PUR. 

These solutions not only address current leakage issues but also prevent recurrence by creating an effective barrier against moisture, ensuring the building’s protection and energy efficiency.

Preventing future damage in buildings

Implementation of materials resistant to extreme weather conditions

To prevent future damage, it is essential to use materials that can withstand adverse and extreme conditions. Molins Construction Solutions has specialised products such as high-resistance mortars for structures exposed to freeze-thaw cycles, like PROPAM® REPAR TECHNO 40. 

It is also crucial to apply anti-corrosion coatings. For example, our technical repair mortars with MCI technology, like PROPAM® REPAR TECHNO 40 MCI and TECHNO FLUID MCI, have been successfully used on bridges and foundations exposed to heavy rainfall, saltwater, and extreme temperatures, significantly extending their lifespan.

Waterproofing techniques to prevent leaks

Various techniques, such as flexible cementitious liquid membranes like PROPAM® IMPE FLEX, or polyurethane systems like PROPAM® PUR, offer comprehensive protection against water leaks. These solutions have been applied in projects like roof rehabilitation on historic buildings and industrial basements, preventing structural damage from moisture and ensuring long-term preservation.

Structural design adapted to extreme weather events 

Designing structures to withstand different weather conditions is crucial for safety and durability in harsh environments. Hurricanes, torrential rains, strong winds, and extreme heatwaves represent significant challenges that can compromise structural integrity if not addressed from the initial planning phase.

For example, in coastal regions prone to storms and high salinity, it is crucial to integrate corrosion-resistant materials into metal structures and high-resistance reinforcements capable of withstanding extreme wind loads. Similarly, in areas exposed to large thermal variations, using materials that better withstand these changes can help prevent cracks and premature deterioration.

Incorporating adverse weather conditions and extreme events as a central factor in the structural design of a project not only prevents unexpected incidents but also significantly enhances safety for people and ensures the continued operation of critical infrastructure. Additionally, including innovative and resilient materials as part of an adapted design adds superior value to the project, reflected in greater resilience, lower maintenance, and longer lifespan.

Advantages of choosing quality materials for building repairs

As previously mentioned, choosing quality materials not only enhances safety in building maintenance projects but also ensures the resistance and durability of structures against an increasingly challenging climate.In a context marked by the effects of climate change and the growing frequency of extreme weather events, incorporating high-performance materials is a key investment to prevent future damage, protect buildings, and ensure their long-term functionality.
