STRUCTURE CLEANING

The sewer system is cleaned using hydro (water) jetting and/or a mechanical cleaning process that removes scale, buildup, debris, blockages and restores flow in the existing pipes. 

LINING & REINSTATEMENT

Your cleaned pipes or manhole are lined with resin saturated liner. The liner cures via steam. Robotic equipment is used to reopen branch lines.

Sewer Mainline CIPP Rehabilitation

We offer No-Dig Trenchless Mainline Rehabilitation that provides a minimal impact on the surrounding environment and a long-term solution

Cure in Place Pipe (CIPP) is a technology that prevents ground dig ups, lessens traffic disruptions and makes your sewer pipe as good as new!

CIPP is considered as most economical method of sewer pipe rehabilitation.

When the sewer pipe requires rehabilitation due to poor condition, our crew of experienced rehabilitants can reline the full length of the pipe using our Cured-in-Place Pipe (CIPP) full reline method.

Process

Our engineering department assesses the condition of the pipe based on the CCTV reports of the sewer lines provided by the client. After assessing the pipe conditions, the liner thickness is designed accordingly.

We televise the lines before relining to confirm the condition of the pipe.

The line is being prepped for relining by removing/cutting roots, encrustation, grease, protruding services etc.

The final liner design will be submitted to customer for approval.

Jointless felt liner saturated with a high strength resin is inserted into the full length of line (from manhole to manhole).

After the liner is in place then it is steam cured. As a result of steam curing it forms a brand-new pipe layer inside the existing pipe.

When liner has fully cured and cooled, excessive liner at the start and finish points are cut flush with the pipe interfaces in the manholes

The service connections are reinstated via robotic cutting equipment

A post rehabilitation inspection is performed and submitted the reports to customer.

WHAT ARE THE BENEFITS?

Manhole, Pump Station, and Culvert Rehab - Cured in Place (CIP)

For manholes, pump stations and culverts rehabilitation, Cured-in-Place liner system is the best solution for fixing the deteriorated structures. This manhole rehabilitation system extends the life of the structure up to minimum 50 years.

Cure-in-Place (CIP) is the technology that prevents the ground dig ups, lessen the traffic disruptions and make you sewer manholes, pump stations and culverts as good as new.

CIP is considered as most economical method of manhole, pump station and culvert rehabilitation compared to open cut, dig and install of the new structures.

When condition of the sewer structure is bad, it needs to be rehabilitated, and our experienced crew is there to restore the structures using our Cured-in-Place (CIP) method.

Process

Every single structure is inspected and exact measurements are recorded along with thorough field notes. We gain a complete understanding of each structure’s needs prior to a liner ever being put into production. A custom liner is then fabricated for each structure.

At the jobsite, the structure is high pressure cleaned and etched.

Pipes are trimmed/grouted around as needed.

Benches at the bottom of the structure are rebuilt as needed and a bridge platform is placed just over the invert channel allowing for uninterrupted flow during the installation.

The liner is then completely saturated inside and out using our epoxy resin and lowered into the structure.

Once the liner is in place, it is promptly inflated, (via an internal inflation bladder), using both steam and air pressure. The amount of air pressure exerted is in excess of hydrostatic head pressure of infiltration. (The liner will bond to a wet or dry surface.) Curing takes place in approximately one hour.

After curing is complete, the inflation bladder is removed, laterals are re-opened and the plywood bridge over the invert channel is removed. Liner installation is complete. Total time start to finish is usually 4-6 hours. Sewage flow has continued this entire time.

WHAT ARE THE BENEFITS?

Spot Repairs - Cured in Place (CIP)

We use the best Cured-in-Place-Pipe lining system specifically made for laterals & spot repairs!

It is common for only one or few sections of pipe to show cracking, fracture, or offsets.

In this case, with our edge-cutting technology, we can repair the damaged sections only without any excavation or ground disturbance.

We use epoxy and fiberglass liners that are pulled or pushed into place.

CIPP Structural Spot Repair is the most practical and cost-effective method to repair a short length of damaged pipes with diameters from 100mm to 1200mm and continuous length up to 3.0 meters.

Process

The point repair process begins when a high velocity jetter is used to clear all debris and foreign material out of the pipeline.

Video inspection is the next step. A video camera must be used to determine the location and condition of the damaged pipeline.

The fiberglass mat is wet out with the epoxy, wrapped around a rubber mandrel, then wrapped in polyethylene to protect it, U-folded and taped to hold it tight and then rolled onto a spool ready to go to the jobsite.

The liners can be pushed or pulled into place between any two access points, clean outs, manholes, etc. Pulled in place is often the preferred method as two lifelines are available for adjustments. The pulled liner will easily negotiate T’s, Y’s, and bends of up to 90 degrees. Location of transitions, if any, is not a concern.

Once in place, the steam line is connected to the mandrel and steam pressure applied for the indicated time span (usually 45 mins. to 2 hours depending upon which epoxy is used and the size of the liner).

After the proper curing time (usually 2-3 hours), the bladder is deflated, and then removed ending the point repair process.

WHAT ARE THE BENEFITS?

CCTV Inspection and high Presure flushing

Our process starts with an in-depth assessment of your existing structures. We use advanced technology to capture their conditions and take measurements

Closed Circuit Television (CCTV) Inspection

Televised sewer inspection can be used for different reasons such as:

Pre-Acceptance – we do inspection of new or renewed sewers that will help engineers and clients to ensure that the construction was done as per specification and drawings to meet the user needs.

Trouble shooting – you may need visual inspection to access the defects to make the investigation of the problems and to decide the course of action need to be adopted.

Routine Operational Requirements – we are always there to help you for the CCTV inspection of your sewer line that help you if you need to make pro-active inspection, it identify the present condition of your system and for planning operation and maintenance (O&M) and rehabilitation of the sewer system.

FAQ's

Trenchless sewer repair eliminates the need for large-scale destruction of floors and landscaped areas to conventionally replace the damaged pipes, the costs associated with replacing those surfaces, and limits the exposure to health and environmental risks created by major sewer excavations.

On large-scale commercial projects, an aggressive timelines are pursued, with anywhere from two to four liner installations a day.

The CIPP process is a marvel of modern technology. The crew inserts a fabric tube impregnated with resin into an existing pipe, inflate it and then apply heat to the tube that involves steam to bond it to the pipe.

Depending on the diameter of the pipe, approx. 200 m of pipe can be relined through single installation.

There is a minimal reduction in diameter, but the smooth bore interior of cured in place pipe typically improves flow rate. Also, pre-cleaning typically removes encrustation that has restricted flow.

The CIPP liners have an expected useful life of between 35 and 50 years, which is comparable to a new pipe installation.
