About Sure Shot
Sure Shot has been serving the Mid-Atlantic region’s trenchless technology needs for years. Our team of experienced technicians are qualified in everything from HDPE fusion to Pipe Bursting to HDD installation. We service Water, Sewer, Electric, Gas, and Communications.
Why Horizontal Directional Drilling?
Horizontal Directional Drilling is by far the most popular form of trenchless technology used today. It provides a cost-effective alternative to more traditional open-cut methods of construction. It can increase production while decreasing restoration time and expenses, making HDD the preferred trenchless choice of all utility markets.
How We Work
Prep & Planning
All existing utilities are marked and test pitted to determine a safe bore path. Once we determine the inverts of the conflicting utilities they can be safely avoided by steering the drilling head.
The HDD crew will begin by making a 6” pilot hole. The actual depths and location of the drilling head will be tracked using a walkover radio wave location device.
After a successful pilot hole is completed, the HDD crew will begin to make the hole larger. This process is known as pre-reaming. Several passes will be necessary to enlarge the hole to 1.4 times the size of the product.
The Drilling fluid may vary depending on the soil. However, a typical mix would include three bags of high-yield bentonite per 750 gallons of fresh water. A viscosifier, stabilizer, and/or polymer may be added if deemed necessary by the HDD crew.
A HDPE pulling head will be attached to the product pipe by means of butt-fusion. This will seal the end of the pipe and allow the pipe to be connected to the drill string. After the product pipe is installed the
During the installation of the product pipe, some drilling fluid will be forced from the hole as the product pipe occupies its space. This fluid will be gathered in a receiving pit and collected with a vacuum system. After the installation of the product pipe, the remaining drill fluid will set up around the pipe acting as a grout.
