No dig, no problem

When main lines leak or corrode, they can damage above ground surfaces, cause pollution, and start severe flooding in treatment or industrial facilities. Hill Services uses various trenchless technologies to combat these and other problems caused by Inflow and Infiltration (I&I), including:

Hill Services uses the most technologically advanced methods of Cured in Place Piping (CIPP), including Inversion, Pull in Place and Point Repair for drain lines ranging from 3” to 72”.

Hill Services installs CIPP liners that are able to withstand heat, caustics and high pressure, commonly found in Industrial settings.

No dig, no problem

Hill Services rehabilitates buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional “open cut excavation). “Launching and receiving pits” replace the trench needed by conventional excavation methods. Hill Services rehabilitates all different types of pressure pipelines from 4” to 20” with deployments of up to 5000 foot pulls for oil, gas, water, and process lines.

Equipment: 5 Key Pieces

Underground Technology Methodology

Methodology

An expanding device called an expander head, which may be either pneumatic or hydraulic, is introduced into the defective pipeline through a launching pit. As it travels through the pipeline toward the receiving pit it breaks the pipe into many small pieces, pushing the pieces into the surrounding soil. New pipe is attached to the back of the expander head, replacing the line immediately.

Less Disruption, Cleanup and Cost

With Hill Services Trenchless Technology, you can expect to completely restore existing pipes, without the above ground disruption associated with traditional digging. Our Trenchless Technology will extend the life of your existing pipes, leaving a minimal carbon footprint, allowing you to get back to producing products efficiently and or everyday life.

Always consistent

Created for durability, our certified, third-party tested equipment and materials are engineered and manufactured to meet project specifications on an individual basis. Our high performance products are consistent in producing results that work, and are very user friendly.
Underground Technology Cured In Place Piping CIPP 9

Place Piping

Cured In Place Piping (CIPP)

Using CIPP continuous inversion, we have the ability to line pipelines with diameters ranging from 2” to 48”—in most cases less than a day. This “true” inversion method allows us to negotiate 22s, 45s, and 90s with ease. Our liner material allows our installers to line through transitions without changing its structural properties.

More customer satisfaction, needs met, and quality control

  • Returning production to the drain line sooner
  • Quality Control
  • Safety a Top Priority

How it works

A resin-saturated felt tube made of polyester is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). Little to no digging is involved in this trenchless process, making for a more environmentally friendly method than traditional “dig and replace” pipe repair methods. The liner can be inverted using water or air pressure. The pressure required for inversion can be generated by using pressure vessels. Hot water, ambient cured or steam is used to cure the resin and form a tight-fitting, joint-less and corrosion-resistant replacement within a pipe. Service laterals are restored internally with robotically controlled cutting devices. Once the lateral connection has been “cut back in” they can be sealed using end seals. The rehabilitated pipe is then inspected by closed-circuit television (CCTV).

Why we do it

  • More economical than traditional excavation
  • Allowing critical production to resume more quickly
  • Less disruptive compared to traditional excavation
  • More environmentally friendly compared to traditional excavation

Underground Technology Manhole Rehab

Manhole

Manhole Rehab

Our manhole rehabilitation specialists can solve your manhole Inflow and Infiltration (I&I) problems; restoring your structures to “better than new” condition in less time than it would take to replace them — and for a fraction of the cost.

Our technicians use a wide range of 100% solids, zero-VOC epoxies to meet your exact requirements. These ultra high-build products can be sprayed or troweled-on to achieve a 1/4 inch (250 mil or greater) wet-film thickness-on vertical or overhang surfaces without sagging. They are modifiable to meet specific flexural modulus and strength, cure fast even under water, and provide premium corrosion resistance where high concentrations of hydrogen sulfide, sulfuric acid, sodium hydroxide, hydrocarbons and an array of other chemicals are present.

Video Inspection

Hill Services Pipeline Video Inspection Equipment with High definition, pan & tilt capabilities along with a digital video, log observations, generated reports and directly linked to asset-management software. With our Pipeline video inspection equipment, Hill Services can video inspect Drain Lines from 2” to 72” in diameter.

We cover Nuclear, Oil & Gas and heavy industrial and manufacturing sectors. Our video inspection CCTV Rovers/Cameras can be used in drain pipes ranging from 2”-72”, Lengths up to 5,000 Linear Feet with 45 and 90-degree bends, and to deepest pipelines of 50 feet.

Our Video Inspection reports help determine the overall condition of the existing host pipe, Identify (I&I) Inflow & Infiltration/Premature Failures, Diameter size, length & pipe type. Hill Services will provide a complete written video inspection report with Pipeline Mapping & Video Record documentation provided upon completion of the project
