6 Truths About Building in Hazardous Areas
Building resilient homes in hazardous environments is crucial for ensuring safety and durability. In a recent episode of the Building Design, Prime Time Podcast, building designer and expert Frank spoke to Amelia and shared key insights on constructing homes that can help protect and reduce damage when disasters such as bushfires, floods, and severe storms strike. Frank provides advice on this focusing on the best materials and construction techniques for hazardous conditions, while also considering warranty implications.
Understanding Environmental Risks
Identifying environmental hazards is the first step in resilient home construction. Each environment presents unique challenges, whether it’s bushfire zones, flood-prone areas, or regions with severe weather. Conducting thorough site assessments helps in designing homes that can withstand these specific threats. This crucial step informs decisions on material selection and architectural design, ensuring that homes are built to last.
Fire-Resistant Building Materials
In bushfire-prone areas, using fire-resistant building materials is essential. Using materials like non-combustible metal roofing and fibre cement siding could be a great option. These materials can withstand extreme heat and reduce fire risk. Other fire-resistant materials include brick, stone, and concrete, which provide robust protection against flames and heat. The importance of integrating design elements like ember guards and non-flammable landscaping are items that may assist and give you more time to escape from your home and locate to safety during a bushfire. Creating defensible space around the home is vital for fire safety. In these environments, a bushfire assessment will determine a bushfire attack level (BAL). The BAL rating determined by the assessor will specify minimum building requirements to help protect against bushfires.
Flood-Resilient Construction Techniques
For homes in flood-prone areas, implementing flood-resilient construction techniques is critical. “Elevating structures above potential flood levels is a key strategy, This can be achieved with raised foundations or stilts, which protect the home from water damage. Flood-resistant materials, such as concrete, metal, and water-resistant plasterboard, are recommended for the lower levels of the home. These materials are durable and can withstand water exposure, minimising repair costs. Homeowners should be aware that using certain materials outside their recommended conditions may void warranties, particularly in flood-prone areas.
Wind and Storm-Resilient Features
In areas prone to strong winds and storms, additional structural reinforcements are necessary. Securing the roof and using impact-resistant windows and doors are essential. Reinforced concrete and steel frames offer superior wind resistance, ensuring the home’s durability during storms. Storm shutters and bracing systems to protect against windborne debris are also recommended in harsh, windy and storm prone areas. These features can prevent significant structural damage and protect the occupants, It’s important to review warranty terms for these materials, as exposure to extreme conditions may affect coverage.
Corrosive Environments and Material Selection
Building in corrosive environments, such as coastal areas, requires special consideration due to the damaging effects of salt and moisture on building materials. The need for corrosion-resistant materials like stainless steel, treated wood, and specialised coatings are important to consider in these types of environments. Homes near the coast are exposed to salty air, which can accelerate corrosion and degrade materials. Using corrosion-resistant materials and applying protective coatings can extend the lifespan of structures in these environments. It’s also crucial to check the warranties of these materials, as some manufacturers may exclude coverage for corrosion-related damages if the materials are not maintained properly.
Compliance with Building Codes and Insurance Considerations
Building codes are designed to ensure that homes can withstand specific environmental hazards. Hiring architects, building designers and builders familiar with these regulations is crucial. Working with professionals experienced in hazardous environments improves the level of compliance and safety. Securing adequate insurance coverage is vital for financial protection against natural disasters. Understanding the limitations and exclusions of warranties and insurance policies is also essential.
Building resilient homes in hazardous environments involves careful planning, selecting the right materials, and adhering to building codes. As discussed by Frank and Amelia on the Building Design, Prime Time Podcast, choosing fire-resistant, flood-resilient, and wind-resistant materials can significantly enhance a home’s durability. It’s also crucial to understand the warranty implications of using specific materials in extreme conditions such as corrosive conditions.
