Two standard methods are often employed when installing underground utilities like water and gas pipelines: traditional excavation and moling. While traditional excavation has been the go-to technique for decades, moling services have become a convenient and efficient alternative. This blog post will delve into the differences between these two installation methods, highlighting their respective advantages and drawbacks.
What is Moling?
Moling, also known as trenchless technology, is a non-invasive method of installing underground utilities without requiring extensive excavation. It involves creating a small entry and exit point on the surface and using a mole or thrusting device to create a tunnel underground. This tunnel serves as a conduit for the utility pipe, which is subsequently installed by pulling it through the tunnel.
Advantages of Moling
One of the key benefits of moling services is their minimal disruption to the surrounding environment. Unlike traditional excavation, moling requires only a small entry and exit point, reducing the need for extensive digging. This results in fewer disruptions to landscaping, driveways, and other structures, making it an ideal choice for installations in residential areas or properties with limited space.
Moling significantly reduces the time required for installation. Traditional excavation can be time-consuming, involving excavation, pipe laying, and backfilling. In contrast, these services allow for quick and efficient installation, as the mole can create the tunnel and pull the pipe simultaneously. This translates to less downtime, minimised inconvenience, and reduced costs.
Drawbacks of Moling
While moling presents numerous advantages, it may only suit some installation scenarios. The feasibility of using moling services depends on the type of soil and ground conditions. Hard soils or areas with rocks and tree roots can pose challenges for moling. Traditional excavation may be the most viable option.
Traditional Excavation
Traditional excavation, a tried and tested method employed for many years, involves digging trenches to install underground utilities. Its suitability extends to various ground conditions, allowing for a thorough site inspection. This inspection is vital as it helps identify and address potential issues like pre-existing pipes or underground structures during excavation.
Despite its longstanding use, traditional excavation does have its limitations. A significant disadvantage lies in the extensive digging required, which not only consumes a substantial amount of time but causes disturbance to the surrounding environment. Besides, reestablishing the site to its unique condition after the installation can be difficult and costly.
Conclusion
In the realm of underground utility installation, both moling and traditional excavation methods have their place. While these services offer minimal disruption and faster installation, traditional excavation provides thorough site inspection and is suitable for a wider range of ground conditions. Counselling with a proficient utility installation supplier can offer assistance in deciding the most appropriate approach for your needs.
