Emerging Technologies

New advancements in trenchless technology such as Automated Defect Recognition (ADR), machine learning, artificial intelligence, advanced processes, equipment and materials help trenchless applications become safer and more efficient, as well as to provide stronger, more flexible and durable solutions for repairing failing underground infrastructure.


Renovate old or deteriorated drains and sewers from 1¼” to 12″ diameter with a brush coating system. The coating applied provides a damp-proof, corrosion resistant, wear-resistant and non-corrosive lining. Several coats can be applied within the same pipe. Renovate entire piping systems; for example, apartments or blocks of flats with minimal disruption, avoiding costly excavation

Double Stack

The double stack lateral lining system process utilizes a single piece of cured-in-place pipe (CIPP) that rebuilds the main/lateral connection (including compression gaskets). A main liner tube measuring is installed in the main pipe and includes a vertical lateral portion that forms a T-shape. This T-shaped liner is outfitted with a flange shaped compression gasket that is seated into the lateral connection. The vertical lateral liner portion extends to another upside-down TEE (hence the term double stack). From this point, two lateral liner tubes would extend laterally toward properties on opposite sides of the road. Additionally, it is not uncommon for the liner to transition in diameter.   To ensure water tightness, hydrophilic O-rings are attached to the terminating ends of the lateral liner tubes. 

Multi-Lateral Lining Systems

The multi-lateral lining system process allows for two opposing service connections to be renewed at the same time.  In the past, the process of renewing service connections across from one another involved multiple steps. The main liner tube is inverted into and through the main pipe, and as it reaches the service lateral pipes, the lateral liner tubes simultaneously invert and extend up into the lateral pipes.  The end result is a continuous liner with uniform CIPP thickness, requiring no reinstating of service connections. 

Sectional/Main/Lateral Connection Liner

The sectional connection liner process renews mainline pipes from 8 to 12 inches in diameter and in continuous a length up to 6 feet while simultaneously renewing a connection and the lateral service pipe. The liner can be inverted anywhere in the pipe with no trimming or cutting. The result is a structural, root proof, water-tight liner. Gasket sealing technology is used at the terminating points of the liner by embedding seals made of hydrophilic material between the liner and the host pipe to ensure a water-tight seal.

Manholes have traditionally been adjusted to final grade using brick, block and precast adjustment rings. Alternatives to these construction materials have entered the market over the years and the most recent to do so is an adjustment ring system manufactured from expanded polypropylene (EPP). The EPP material provides for the most advanced concrete-alternative manhole and catch basin grade adjustment system available today.  EPP is renowned for its exceptional strength to weight ratio, durability, chemical resistance and long service life under harsh conditions.  Available in round, square and rectangular shapes, one worker can install the EPP grade ring system in just minutes to within a quarter inch of finished grade without the use of mortar or shims.  The rings are HS-25 traffic rated, are watertight, and, where concrete rings break and may cause injury, the EPP system eliminates the hazard, helping minimize the risk of injury. The EPP system dramatically speeds manhole installation or repair time and increases the life expectancy to 50 years or more.

This new hybrid epoxy manhole lining system with high chemical resistance, offers over 250 times the chemical resistance of calcium aluminate and is 200 times more chemically resistant than pure fused calcium aluminate, according to a study conducted by Florida Atlantic University, July 2016. In addition, the product incorporates a formula that contains a broad-spectrum, highly effective antimicrobial agent that has been clinically tested and has been shown to react with key proteins in a microbe’s outer membrane, blocking the transfer of necessary nutrients into the cell.

It can be effectively used as a re-surfacer and liner in a single, simple application. It has been in development for over five years, for use in the wet, humid conditions typically found in manhole environments.
