Might some of you knows, but let me tell you what are utilities that have beneath under the ground.

Nowadays, modern city life is dependent on infrastructure that is hidden under the ground. Water mains, sewers or septic facilities, gas pipelines, electrical wires and more beneath the earth to allow a cleaner and more attractive street for today’s urban dweller. Pictures below shows some of the utility that have underneath under the ground.

Why utility detection and mapping so important? Before any commencement works at a construction site, it is essential for a utility detection survey to take place. By detecting and mapping the location of underground utility, companies can determine the feasibility of any sites. Utilizing modern techniques such as radio detection and ground penetrating radar (GPR) can help up company to save money and time.

Yes, there is a lot of advantages using this method. Advantages of Directional Drilling are:

• Significantly reduced cost and time.
• There is no need to restore damaged roads and railways, green plantations and urban infrastructure.
• Environmentally friendly, safe, reliable and efficient alternative to conventional construction methods.
• Reduces the noise, environmental and safety risk associated with open trench pipe construction.
• Reduce impact on residents and business around construction site.
• Flexibility, as the system can be installed nearly anywhere.
• Negligible soil contamination, as the impenetrable pipe connections are lasting.

Did you know that we can install underground utility without disturbing the surface? What technology that we can use to install underground utility?

Well, now we have Horizontal Directional Drilling (HDD) or as known as directional boring is an innovative trenchless technology that enables us to install underground utility without conventional open trenching. The process used to install utility services underground along the designated bore path over a distance. The process begins when a directional bore machine pushes a bore head connected to hollow pipe into the ground at an angle. As each joint of drill pipe is pushed into the ground a new one is added behind.

It is used for waterways, roadways, shore approaches, congested areas, environmentally sensitive areas and any area where other methods are more expensive. This method suitable for variety of soils conditions and pipe diameters. To more understanding, you can view the video below to get more information on how it works.
