Restore Pipe, Manholes and Structures Without Open-Cut Digging

Innovative Solutions

Hill Services is committed to providing innovative solutions to the industry across the Mid-South where our long-term relationships are based on integrity and reliability. Our approach to designing, building, maintaining and servicing mechanical systems makes us a preferred partner in the industry. Your company depends on systems and equipment that operate smoothly and efficiently. Our highly skilled project managers and technicians quickly assess your needs and develop solutions that work.

Pipe Lining

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 Cured in Place Piping (CIPP), pull-in-place installation, and point repair.

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 inches to 72 inches.

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

Equipment: 5 Key Pieces

Cured In Place Piping (CIPP)

Using CIPP continuous inversion, we have the ability to line pipelines with diameters ranging from 2 inches to 48 inches, in most cases in 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.

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. The rehabilitated pipe is then inspected by closed-circuit television (CCTV).

Why We Do It

Epoxy Coating

Leaking tanks, vessels, or Inflow & Infiltration (I&I) can be problematic, affecting production and adding cost.

By applying 100% solid epoxy coatings to these surfaces, Hill Services can restore them, prolonging their life expectancy and getting your company back to full production faster.

What Are the Benefits?

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.

Epoxy

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 corrosion resistance where high concentrations of hydrogen sulfide, sulfuric acid, sodium hydroxide, hydrocarbons and an array of other chemicals are present.
