Green construction practices can also involve the use of renewable energy sources, such as solar and wind power, to power the excavation and construction equipment, thus reducing emissions.
Focus on reducing noise and vibration pollution during construction: Noise and vibration pollution are common issues that arise during the construction of deep basements, especially in densely populated areas. Noise pollution can cause disturbance and annoyance to the nearby residents and businesses, as well as damage to the surrounding buildings and infrastructure. Therefore, it is important to adopt measures to reduce noise and vibration pollution during construction, such as using low-noise and low-vibration equipment, installing noise barriers and vibration isolators and implementing noise and vibration monitoring and control systems.
Energy-efficient excavation and transportation methods: Energy-efficient excavation and transportation methods can help lower the energy consumption and cost of basement diaphragm wall construction. For example, hydraulic excavators and cranes can be used to dig and lift the soil and the diaphragm wall panels, instead of diesel-powered machines, thus reducing fuel consumption and emissions. Energy-efficient transportation methods can also involve the use of electric or hybrid vehicles, as well as the optimisation of the routes and schedules, to transport the materials and equipment to and from the construction site, thus minimising travel distance and time.

Frequently Asked Questions
Diaphragm walls are reinforced concrete walls constructed in the ground using an under-slurry technique developed in Europe. These walls are generally used for constructing structures with deep basements in congested areas, as they can be installed close to existing structures. The walls are formed by excavating a narrow trench that is kept full of an engineered slurry fluid. This way, concrete diaphragm walls with thickness ranging between 300 mm to 1200 mm can be formed as deep as 45 metres underneath. Inclined rock or soil anchors are used for this purpose.
Retaining walls are used to retain soil or other materials, while diaphragm wall are used to create a barrier between two areas. Retaining walls are typically constructed above ground, while diaphragm wall are constructed below ground. Diaphragm wall are also more flexible in terms of their plan layout and can be easily incorporated into permanent commercial and residential projects.
Diaphragm walls are an economical and positive solution for large deep basements in saturated and unstable soil profiles. They can be installed to a considerable depth with the formation of walls with substantial thickness. Diaphragm walls are designed to carry vertical loads, thus reducing the construction time of the basement. Further, the noise levels are limited to the engine noise only and there’s no vibration during its installation.
