No Trench, No Problem!
There are probably more utility facilities running beneath the ground on your property than there were a decade or so ago. When installing additional facilities, it's important that the exact depth and location of all underground facilities is established prior to the installation.
Once the depth and location have been established, you can proceed to safely excavate the ground to pave way for the installation. Here is why you should consider going trenchless with the new installation.
There's no telling what can happen mid-way through the installation. An installation that had been scheduled to take a day or less could easily end up taking up to three days. Unfavorable weather conditions and the late delivery of utilities (e.g. cables) to be installed are just two examples of factors that may contribute to installation delays.
With open-cut drilling methods, the situation described could easily pose a threat to your children's safety and that of anyone who might access the work area during the installation/delay period. The possibility of one falling into the open pits left after excavation cannot be ruled out.
Trenchless drilling methods (e.g. horizontal directional drilling and micro-tunneling) offer a solution to this problem. The mentioned techniques allow for the removal of material from beneath the ground without the need for extensive surface excavation.
In horizontal directional drilling for example, suction excavators are used to create the path of installation for new cables/facilities. The excavator's nozzle is pushed into the ground and air/water pressure 'sucks in' soil and other materials from below the ground. A truck-mounted tank is used to collect and store whatever comes through the nozzle.
Trenchless drilling leaves no open depressions that could compromise your safety during the installation exercise.
You want the new installation done, but you don't want to run bankrupt in the process. Trenchless drilling is a cost-effective alternative to open-cut drilling. This cost-effectiveness is seen in a number of ways.
For example, you'll have less of a mess to clean up after the installation has been done. Since there's minimal surface disruption on thee landscape, you wouldn't have to worry about huge heaps of soil that need to be eliminated or open depressions that need to be covered/filled.
Perhaps more important is the fact that trenchless drilling allows contractors to follow the most direct route between two points along the path of installation provided that the right-of-way allows for it.
With open-cut drilling, presence of obstacles on the landscape creates the need to follow existing utility easements. This could increase the cost of installation by a significant margin.
