A frac-out occurs when drilling fluid penetrates fractured bedrock, or seeps or flows into the rock and sand that surrounds the bedrock and travels toward the Earth's surface. A frac out frequently occurs as the result of excessive down-hole pressure caused by a poor choice of drilling fluids… View Full Term

The core cutter method is a test used to determine the in-situ dry density of soil. It is only used in fine-grained cohesive soils without stones. The test requires cylindrical core cutters about 130 mm long and 100 mm in diameter. The bulk density of soil can be easily calculated using…
An invert level is defined as the elevation of the inside-bottom of a pipe, trench, culvert, or tunnel. It may also be considered the "floor level" of a pipe. Invert levels are essential for assessing the flow in a piping system. For example, the invert of a municipal sewer…
Hoop stress is the stress that occurs along the pipe’s circumference when pressure is applied. Hoop stress acts perpendicular to the axial direction. Hoop stresses are tensile and generated to resist the bursting effect that results from the application of pressure. Three principal…
Site investigation is an integral part of any construction project, and should be attributed as much significance as would be ascribed to any other part of the project. The risk associated with undertaking a project without adequate site investigation is monumental. It's wiser to be…

Horizontal directional drilling (HDD) is a conventional method employed by cities and construction workers to install utilities and plumbing underground. Unlike traditional underground installation, HDD does not require open trenches to complete. Equipment Needed for HDD As horizontal…
Aging sewer pipelines is a growing concern in many municipalities. This issue has led to an increase in activity aimed at rebuilding or rehabilitating current sewage infrastructure. However, it is often necessary that existing sewer systems remain operational during ongoing construction…

Tunnel boring machines (TBMs) and microtunnel boring machines (MTBMs) are used to construct underground tunnels and passages with circular cross-sections. They both use a drilling mechanism, known as a cutting head, to remove material and advance the equipment forward. However, both these…
Microtunneling and guided boring are often erroneously used interchangeably in the construction industry. While both these trenchless boring methods may seem identical, there are a number of key differences between the two that need to be considered when deciding which technology is…

Pipe bursting is an advanced trenchless solution designed to replace deteriorating pipes without the need for extensive excavation. By employing different techniques,…
When it comes to trenchless excavation, choosing the right trenchless boring method is crucial to the success of your project. Trenchless boring, also known as…
Horizontal directional drilling (HDD) and auger boring are two common methods of trenchless excavation used in construction projects. Both methods offer unique benefits…
Trenchless technology has revolutionized the construction industry in the past few decades. With the advent of trenchless techniques like pipe jacking and…
The inadvertent return of drilling fluid is common in horizontal directional drilling (HDD) projects, and though not harmful to the environment, inadvertent returns are…
Requirements for horizontal directional drilling (HDD) environmental planning and construction monitoring vary greatly across North America, but regulatory obligations…
