Global Infrastructure Crisis

2009 Report Card for AmericasInfrastructure per ASCE Wastewater = D Bridges = C

Investing in infrastructure, has proven to bebeneficial in the past, with a $7 return for every$1 of investment

Trenchless (no-dig) technologies are more cost-

effective and less disruptive pipeline solutions toother traditional methods These technologies benefit the health of people

and the economy


4/34

Global Water Crisis

The Clean Water Act wasestablished 35 years ago tohelp prevent spills andenvironmental damage

The EPA estimates there aremore than 40,000 sewer spillseach year

Sinkholes are becoming a more

common occurrence Insituforms flagship cured-in-place pipe technology helps toaddress these and otherproblems


5/34

Insituform was established in 1971 with the invention ofthe cured-in-place pipe method of underground pipelinerehabilitation

Developed by EricWood in the UK,the Insituformprocess was the firstto rehabilitateunderground

pipelines withoutdigging anddisruption

Insituform History

Insituform working in Denver, Colorado


6/34

Developed in 1971, cured-in-place pipe (CIPP) is atrenchless technologydeveloped by Insituform

The end product is a

jointless, seamless, pipe-within a pipe that protectsagainst spills, breaks andpipeline leakage

Insituform has installed over15,000 miles of CIPP andhas been the industryleader for over 35 years

What is CIPP?


7/34

Benefits

Eliminate infiltration and exfiltration

Restore structural integrity

Prevent sinkholes and surface settlement

Eliminate joints, root intrusion and leaks

Increase flow capacity

Protect pipes from corrosion

Increase pipe strength

Reduce maintenance

Minimal traffic disruption

Fewer social costs to open-cut

Suitable for irregularly shaped pipes and changesin pipe diameter


8/34

CIPP Installation

Thermosetting resin isinjected into a felt tube

The tube is inserted into anexisting host pipeline by

either pull-in or inversion The tube is inflated to thesize of the host pipe

The CIPP tube is cured

using hot water or steam Ends are cut and the final

product is a fully-functionalpipe-within-a-pipe

Wet Out

Insituform has seven wet out facilitiesstrategically located throughout North America

All facilities are ISO-

certified and complyto industry safetystandards

Quality is constantly

regulated and makesuse of the mostadvanced wet outtechnologies


14/34

Resin - Once cured, thermosetting resin retainsits shape with no residual memory.

Resin types:

1. Polyester2. Vinyl Ester

3. Epoxy

Polyester resins are most used in gravity sewerrehabilitation due to their high flexural modulus,low tensile elongation and good chemicalresistance.

iPlus Composite

Reinforced with carbon and glass fibers, iPlusComposite cost-effectively providesenvironmental benefits, increases flow rate,minimizes disruption and won Innovative NewProduct Award at No-Dig in 2007.

iPlus Infusion

iPlus Infusion is Insituforms cured-in-place pull-in and steam-cure method. It offers superiorphysical properties, minimal disruption, andenvironmental benefits for small diameter pipes.

Insituform has developed new CIPP solutionsfor trenchless construction
