Water damage is one of the most common issues facing buildings and structures. It can breed mold, create structural damage, and contribute to poor indoor air quality.
Fortunately, cutting-edge waterproofing technologies are helping to combat the harmful effects of water. Here are five innovative waterproofing materials that are gaining traction in the industry:.
Active Water Management Systems
As Arizona continues to wrangle with the effects of the drought, there is a divide between the city and rural communities. While most cities are reassuring their residents that water supplies are secure, the news is filled with stories of wells running dry and businesses closing. The best solution to these problems lies in creating reasonable regulations that will allow homeowners, farmers and businesses to prosper.
One innovative way to help address the issue of water shortages is through the use of passive treatment systems. These are less costly than traditional systems because they don’t require consistent human intervention. Instead, they rely on natural chemical, biological and biogeochemical processes to treat the water. A passive system can be anything from a constructed wetland to a permeable reactive barrier. The advantage of passive systems is that they are often more aesthetically appealing and blend in with the landscape than an active treatment system, which may be an industrial eyesore for the surrounding neighborhood.
Another innovation to tackle the water shortage problem is the use of recycled water. This water is treated wastewater that has been repurposed for non-potable applications. It can be used for building construction, dust control and concrete mixing and curing, reducing the strain on traditional freshwater resources. However, the success of recycled water systems relies on a number of factors, including water quality assurance, dual piping infrastructure and regulatory compliance (Amaral et al., 2020).
Advanced Coating Systems
As technology advances, coating systems are evolving to meet the needs of modern construction. For example, smart coatings respond to environmental changes, such as temperature or humidity, and alter their properties accordingly. Some also provide additional functionalities, such as antimicrobial or self-healing capabilities.
In addition, many new coatings have been formulated to reduce VOC emissions and support sustainability initiatives. Choosing the right coating system for each project is critical to achieve the desired results. It’s important to understand the different options available and how they apply to specific building types and conditions.
For instance, commercial and light industrial projects often require high-performance coatings to withstand abrasion, chemicals, moisture and other harsh environments. Parylene conformal coatings are a good choice for these applications because they offer the durability and aesthetics owners demand while protecting against corrosion and emitting low VOCs.
Coating technologies are essential for a number of industries, including the energy and medical fields. For example, coatings help prevent corrosion on turbine blades and improve the efficiency of wind power generators. They also protect medical devices from bacterial growth and reduce friction between implants and patients’ bodies, while making them more biocompatible and less likely to trigger rejection. Corrosion prevention coatings are a necessity for communication towers, which are exposed to extreme weather and corrosive elements that can damage the structure. Cutting-edge coatings can protect these vital structures and ensure continuous communications for everyone.
Self-Healing Materials
Self-healing materials are a transformative innovation in construction technology, with the ability to autonomously repair damage and maintain structural integrity. By minimizing the need for regular repairs and maintenance, these cutting-edge substances can significantly reduce associated costs and maximize durability.
Self-repairing materials use encapsulated healing agents or microvascular networks to automatically react to the presence of cracks or other types of damage, and then initiate self-repair. These materials can be incorporated into concrete, metals, asphalt, and other commonly used building materials.
When these materials are combined with IoT sensors, they can monitor structural health in real-time and alert users of potential problems before they become major issues. This enables proactive maintenance, decreasing the risk of damage and improving safety. It also allows users to make informed decisions about repair and replacement options, resulting in significant cost savings for the project.
The self-healing properties of these materials can also improve energy efficiency by preventing leaks and cracks. This can cut energy consumption by 30-50%, reducing overall costs and environmental impact.
Moreover, self-healing materials can be used to fortify structures and protect them against harsh environments, such as earthquakes or chemical exposure. The technology offers a wide range of applications, and researchers are continuing to explore the use of nanotechnology to enhance the capabilities of these innovative substances. As such, they can provide even greater resilience and support the growth of greener, more sustainable buildings.
Nanotechnology
Using nanotechnology in waterproofing materials can help to improve durability and support sustainability. This is important as building materials are a major contributor to global waste. Construction sites produce huge amounts of material wastage, from concrete and steel to paints and plasters. These are often disposed of as hazardous waste, which poses health risks for workers and the general public and is damaging to natural resources. By developing and utilising innovative materials, such as polyurethane liquid membrane waterproofing, these problems can be avoided.
Nanotechnology is a relatively new field of science, but it is already impacting the manufacture of many building materials. By adding nanotech particles to glass, steel, concrete and coatings, the properties of these materials can be changed. This includes making them water-repellent, resistant to UV or infrared light, antireflective, or even self-cleaning. Nanoparticles can also be used to make structures like roads or buildings smart by embedding them with small sensors that can report back to a computer on their condition.
While this technology is a positive step forward, there are still issues surrounding the safety and environmental impact of nanotechnology in construction. It is vital that further research into the use of nanoparticles in construction is undertaken, especially regarding their potential to cause damage or disease, and that procedures are in place for managing their release into the environment.
