Drain-O-Rooter - Pipe Lining

Trenchless Pipe Liner Technology

The pipe liner system is your no-dig solution for repairing cracked, broken, leaking or root infested small diameter pipes, such as damaged residential and commercial sewer lines.

No more infiltration - No more ex-filtration - No more roots

We can go under landscaping, detached garages, patios, swimming pools, etc.

1. INTRODUCTION Increased awareness of environmental issues such as the protection of ground water has brought to light contamination problems caused by leaking residential and commercial service laterals. The pollution caused by wastewater seepage from sewage systems into our streams, rivers and oceans has become a matter of serious concern. In addition, maintenance concerns such as blockages and root intrusions are major considerations for today's homeowners and property managers. Drain "O" Rooter is involved in cleaning, excavating, replacing, repairing, inspecting and locating sewer pipes and is also active in trenchless rehabilitation such as pipe lining and pipe bursting. Drain "O" Rooter maintains keeping up to date with the latest technology and technical developments that enables us to present you with the most cost effective solutions for your pipeline rehabilitation problems.

2. ADVANTAGES OF A PIPE LINER AT A GLANCE The pipe liner system provides cost effective rehabilitation of small diameter pipes in industrial, commercial and residential areas. Because it is a "no-dig" system, costly excavation and demolition are no longer necessary. The liner is continuous, uninterrupted and smooth with no seams or joints. Pipe liners are installed much faster with minimum inconvenience and disruption compared to excavation. The pipe liner also eliminates serious environmental and landscape damage. There is no damage to your trees or shrubs root systems.

3. DESCRIPTION OF REPAIR METHOD Pipe lining is an inversion system. Based on the existing conditions, a custom-designed liner tube is impregnated with epoxy and can then be inverted into the existing pipe.

3.1 PREPARATION In order to achieve the best results, thorough preparation of the existing pipe is necessary. This includes a top quality TV inspection, cleaning and preliminary measurement checks of diameter and length. During large-scale repairs the stoppage of water infiltration and bypassing flows in the existing pipes may be necessary in order to prepare the existing pipe for lining.

3.2 INSTALLATION (INVERSION)

Depending upon on-site conditions, the pipe liner is installed by inserting the liner through basement drains or small excavations. In the case of partially damaged sections, only the affected beginning of the pipe is repaired. This is known as blind-end installation. The liner materials are selected depending on the pipe condition. Standard liner tubes are used for straight pipes and more flexible tubes are used for pipes with severe bends, angles and transitions from smaller to larger diameters.

3.3 CURING PROCESS

The epoxy resins are selected according to the job requirement and the ambient temperature. Using the ambient process, a liner and epoxy are selected that will enable the reinstatement of service to the pipes within 4 to 12 hours.

3.4 LATERAL OPENING AND CONNECTION

The lining process seals off all side entrances. When using a blind-end method, the liner end itself makes a perfect transition to the original piping.

4. MAXPOX EPOXY RESINS

Our epoxy resins were developed in cooperation with renowned chemical companies Ciba and EMS. They are engineered from a specialized formula that has been tested in practical applications over many years. All the products that are used by Drain "O" Rooter comply with Swiss and German standards and specifications. Among others, we also have a certificate of approval from the Institute for Hygiene in Gelsenkirchen (Hygiene-Institut, Gelsenkirchen).

4.1 LINER MATERIALS AND COATING

The pipe lining materials are made from the finest PU and PVC coated polyester needle felt available in the industry. Along with a coated woven material, these liners are designed to handle many different configurations found in small diameter pipelines.

5. HYDRAULICS

The newly installed continuous and smooth pipe liner evens out bends and joints: The resulting hydraulics of the lined pipe shows an actual improvement of over 100% of the original flow capacity despite the minimal loss of inside diameter. This has been proven by specific hydraulics tests of repaired pipes from around the world. This demonstrates a tremendous advantage that should be taken into account when deciding between disruptive dig-and-replace and the modern day trenchless renovation of existing pipelines with the pipe liner system.

6. WATER TIGHTNESS AND RESISTANCE TO ROOT INTRUSION

The thixotropic epoxy Max Pox bonds the liner to the pipe wall. This bond creates a very tight fit to prevent water from entering or escaping the pipe. In the case of erosion or corrosion from the inside of the pipe due to hydrogen sulfide gases or other corrosives is immediately stopped after relining with the pipe liner system. The institute for Plant Biology in Basel, Switzerland has performed field and laboratory tests that demonstrate that tree roots cannot penetrate or attack the Max Pox epoxy resin. Once a pipe has been lined, it will stay free of root intrusions for the life of the pipe.
