Trenchless Technology

Numerous Trenchless re-pipe options

Pipe Bursting:

Pipe bursting is a trenchless technique used to replace underground pipes without the need for excavation. This method involves employing a bursting tool to pull a new pipe through an existing one, simultaneously fracturing and displacing the old pipe.

Here are some key points about pipe bursting:

How it operates
- A hydraulic or pneumatic expansion head travels through the old pipe, splitting and enlarging it. Subsequently, the new pipe is drawn through, filling the space left by the removed pipe.
Equipment
- Pipe bursting necessitates a pulling machine, pulling rods, an expander head, a retaining device, and a hydraulic power pack.
Advantages
- Pipe bursting is effective, saving time and resources while causing minimal disruption. It is also environmentally friendly as it does not involve the use of chemicals or pollutants, and the new pipes are constructed from eco-safe high-density polyethylene (HDPE).

Spray Lining/ brush coating:

Spray lining and brush coating are methods utilized to protect pipes, from corrosion, wear, and moisture:

Brush coating
- This technique can refurbish pipes like drains, sewers, and water pipes. It is also effective for creating new pipes or reinforcing connections, suitable for pipes as small as 2 inches in diameter.
Spray lining
- Involves applying a thin coating material inside a pipe using a spray head, with the option to add multiple layers for desired thickness. Ideal for small diameter pipe rehabilitation projects.

Additional points to note about spray lining and brush coating:

Preparation
- Prior to coating, pipes may require cleaning to eliminate debris and contaminants.
Material
- Coating materials vary, including options like epoxy or polyurethane.
Flexibility
- Some coatings, like polyurea, are more flexible than rigid ones such as epoxy, able to stretch and bridge gaps.
Environment
- Certain coating systems are eco-friendly, minimizing dust or hazardous waste production.

Cured In Place (CIPP) Lining:

Cured-in-Place Pipe (CIPP) presents a trenchless solution to fix damaged pipes without excavation. This method is commonly used in repairing various types of water pipes, such as sanitary sewers, storm sewers, and drinking water pipes. Here’s how CIPP operates:

Introduce a flexible liner into the existing pipe.
Inflate the liner using water or air pressure.
Subject the liner to heat or ultraviolet light for drying and hardening.
The liner creates a smooth inner surface in the existing pipe, rejuvenating it almost to its original state.

CIPP is suitable for pipes with diameters ranging from 0.1 to 2.8 meters (2–110 inches) and can repair both short and long pipe sections without requiring upsizing.

E pipe- Potable Waterline Epoxy Coating

ePIPE is a patented epoxy coating process designed to seal and restore pipes without the need for removal. Here are some key details about ePIPE:

How it works
A technician clears the pipes, injects epoxy resin, allowing it to cover any leaks, holes, or loose connections. The epoxy coating then hardens to form a new, leak-resistant pipe within the existing one.
Benefits
ePIPE offers a quicker and more cost-effective solution compared to traditional pipe repair methods. It is also a clean process that does not involve opening walls, floors, or ceilings.
Applications
ePIPE is suitable for various environments such as homes, apartments, condominiums, hospitals, hotels, schools, universities, senior living facilities, and government properties.
