Trenchless Technology Seminar on House
Sewer Repair Options Draws
Crowd
A Comparison
Between Trenchless Technology And No Dig Alternatives To
Digging
An estimated 200
plumbers and sewer contractors sat in attendance at a
special seminar at a Pumper & Cleaner Environmental
Expo, in Nashville,
Tennessee.
The
audience listened closely as FORMADRAIN’s senior partners
discussed various problems that can occur with house sewers
(also known as laterals) and repair
options.
Following the presentation, Gerard Marc-Aurele
and Stephane Therrien, who hosted the seminar, answered more
than 35 questions from the floor and during face to face
meetings for 45 minutes.
Mr.
Marc-Aurele, founding president and the inventor of the
Formadrain No-Dig System opened the seminar with a story about
the liability of having to dig when repairing house
sewers.
“We cracked
a single pipe,” recalled Mr. Marc-Aurele, “and when rain later
destroyed underground power wires, etc., the insurance bill was
so high we were uninsurable afterwards. It cost us the
company.” This was the major reason he developed Formadrain’s
exclusive no-dig system.
The next
speaker was Mr. Therrien, Formadrain partner and engineer,
started the main body of the presentation by giving attendees
an idea of the size of the market in house sewer repairs:
“According to the U.S. Census Bureau there were more than 76
million house sewers connected to public sewers in the U.S. in
1990. And at least 50 million of these are more than 30
years old.”
He then proceeded to discuss
various problems that can occur with house sewers (laterals)
including:
- Backups caused by
roots
- Water
Infiltration/Exfiltration
- Installation of non durable material for
laterals such as tar paper
pipes
- Corrosion, open joints, offset joints,
dips, pipe deformation, crushed
pipes
Finally,
various solutions were presented including
- Open
Trench
- Pipe
bursting
- Grouting
- Inversion
Liner
- Pull in Place
Liner
The seminar
ended with a Question and Answer period.
