The IPR Advantage

Pipe Bursting

What: Replacement of the host pipe by fragmenting the existing pipe and installing a new pipe of equal or larger diameter in its place. Application: • Water lines • Sewer mains • Sewer services • Gas lines • Communication ducts

Pipe Bursting All types of pipe can be burst and all types of pipe can be installed: • High Density Polyethylene (HDPE) • Clay • Steel • Fiberglass (Hobas) • Polymer • Ductile Iron • Concrete • Polyvinylchloride (PVC)

Replace pipe for same size or increase capacity by upsizing new pipe.

CIPP

CIPP is a trenchless method of pipe rehabilitation, which involves inserting a felt tube, saturated with a thermosetting polymer into the damaged pipe. Steam heat is used to expand and cure the tube creating a new, long-lasting liner inside the pipe. CIPP is the #1 trenchless technology used in the US for rehabilitation of sewer pipelines. Methods available in water, gas, and chemical pipelines.

Benefits: •Cost effectiveness •Pipe renewal (50+ years) •Low impact •Short timeline • Increased structural integrity •Non disruptive

In the 2007 edition of the AASHTO Highway Drainage Guide, Section 14.5.1.5, Chapter 14 under rehabilitation methods lists Cement Mortar Lining:

“The mortar can be applied by hand, pneumatically (gunite), or by

centrifugal process. The centrifugal process utilizes a lining machine that

dispenses and trowels mortar on the interior surface through an application

head. If necessary, steel reinforcing mesh or reinforcing bars can be placed

prior to the mortar application.”

IPR Geopolymer is a high-performance nano-scaled geopolymer that is specially designed for spray or centrifugal applications

IPR Geopolymer is a trenchless, BPA free, 36”to 156” pipe rehabilitation solution.

IPR Geopolymer has built-in resistance to extreme hot or cold weather conditions during application

IPR Geopolymer Product

IPR Geopolymer has both high early strength and substantial long-term strength gain

IPR Geopolymer has exceptional tensile and elastic characteristics and near-zero porosity.

IPR Ecopolymer is a structural material with compressive strength in excess of 8,000 psi.

IPR Geopolymer Product

• IPR GeoPolymer Nano-Ceramic Mortars incorporate in excess of 50% waste materials such as waste slags, waste silicates, waste fly ash, crusher fines and other processed wastes.

• These materials are introduced and serve as “alternative cementitious” binders as well as “contributing fillers”, such that every particle within the geopolymer is providing some cross-linking characteristic.

• This cross-linking efficiency creates a uniquely dense ceramic product.

• With the use of 50% or more of recycled materials, there is a greater than 50% reduction in CO2 emissions when compared to Ordinary Portland Cement (OPC).

Report Conclusion

IPR personnel were invaluable in the creation of a new ASTM Standard Practice.

ASTMs’ F 36 Committee, Technology and Underground Utilities, recently developed and released , Standard Practice for Installing a Protective Cementitious Liner System in Sanitary Sewer Manholes, F 2551-09.

This practice includes the use of the centrifugally cast concrete lining system.

Spin Cast ASTM in Process

The pipe surface must be clean. Materials must be mixed on a consistent basis, maintaining the proper

water to cement ratio is extremely important! The materials must pumped on a consistent basis. The retrieval speed must be able to be monitored and repeatable to

within 5% of the speed specified. All of these parameters must be able to be verified as being consistent

throughout the entire operation.

Over time the effects of Carbon Dioxide (CO2) and Hydrogen Sulfide (H2S) present in the system’s environment lower the pH of the concrete surface supporting Thiobacillus bacterial growth. (pH <7)

This colonization can occur sometimes in a matter of months in aggressive environments causing accelerated destruction. Lowering the surface pH to <2.

The production of Sulfuric Acid from Hydrogen sulfide is an aerobic-biological process that occurs in the presence of Oxygen. A white or yellow discolored surface indicates the start of the corrosion

MIC Corrosion

TPC Publication 3, Fifth Printing 1990 Sulfur Bacteria, Page 22 Thiobacillus is the most common sulfur-oxidizing bacteria.

This bacteria oxidizes sulfur and sulfide to produce sulfate and sulfuric acid. Corrosion is caused by the sulfuric acid.

Bacteria Life Cycle

• IPR AMS Spray is used with the IPR Pipe Liner adding

an AntiMicrobial System (AMS) • IPR AMS uses static electricity to destroy bacteria and

other microorganisms • IPR AMS does not use leachable toxins or heavy metals

IPR AMS Spray

Bacteria Killing Mechanism

IPR AMS Spray is applied in three steps: 1.Pre-treat the surface with the IPR AMS solution 2.Apply IPR Pipe Liner material 3.Apply the IPR AMS solution during the IPR PL

application or any time afterwards. Water and sewage bypass may be released once the

treated surface has reached a Saturated Surface Dry (SSD) state.
