Infrastructures like roads must be designed and constructed optimally to make sure they can carry out their functions. For one, they help ensure that vehicles and pedestrians can move from one place to another. They also make sure major and minor localities will be connected, which helps in boosting their respective economic condition. Another functionality of the roads is to prevent natural hazards from damaging the communities.

Roads, however, may face wear and damage over time. Hence, they are subjected to reconstruction, which can be done by our team at Presta & Sons. One component that our team must design and integrate into the reconstructed roads optimally is the drainage system.

Problems Encountered by Roads

Some communities can be prone to flood, especially those situated in low-lying areas. If the roads and drainage system are not designed optimally, they can easily face several problems.

First, water accumulation can often be seen on roads in low-lying or poorly drained areas. Without resolving this issue, surface erosion and damage may occur. Second, the existence of floodwater can gradually compromise the structural integrity of roads. Once it infiltrates the road surfaces, the existence of cracks, potholes, and road failure can affect the road’s functionalities.

The occurrence of the previously stated problems can all lead to disruption of transportation. It can heavily affect daily commutes, economic activities, and emergency response times.

Components of Quality Drainage

Multiple components must be present in a quality drainage system. Some are as follows.

•  Effective Stormwater Management: Drainage solutions must integrate effective stormwater management by utilising systems that efficiently collect and channel rainwater away from the road surface. Doing this helps prevent rainwater from damaging the road surfaces.

•  Proper Sloping and Grading: Roads should also be designed with proper sloping and grading to encourage water runoff. These components help prevent water from pooling on the road surface, reducing the risk of damage and other costly issues.

•  Permeable Pavements: Permeable pavements allow water to pass through the surface, reducing runoff and minimising the impact of heavy rainfall on roads.

•  Advanced Culvert Systems: Culverts handle increased water volumes during heavy rain. Maximising them can easily prevent road inundation.

Advantages of Resilient Drainage

Roads subjected to reconstruction may already have been damaged due to daily use. They must then be reconstructed due to heavy rainfall and flooding. As climate patterns become more unpredictable, resilient road infrastructure has become significant, securing connectivity, safety, and the overall functionality of transportation networks.

During road reconstruction, a resilient drainage system must maximise the previously stated components to ensure it will last for a long time. With proper drainage construction, road safety can be enhanced by minimising the risk of accidents and structural failures due to flooding. It can also contribute to economic stability since transportation of goods and services will remain uninterrupted. Ultimately, community accessibility can be maintained through well-designed drainage systems, allowing residents to always travel safely and access vital services.

We, at Presta & Sons, offer resilient drainage solutions that can contribute to the overall well-being of communities. Contact us during road reconstruction to gain their benefits.
