Industry Newsletter |

Welcome
to another edition of the Penetron industry newsletter.
One of the main advantages of the Penetron concrete
waterproofing system is that it is extremely versatile
in its application, it can be applied as a coating,
a dry-shake or an admixture. The cavity-fill method
is yet another effective way to introduce the Penetron
chemicals into existing concrete and waterproof it,
litterally, from within ! |

Product
Feature: PENETRON CAVITY FILL METHOD |
|
|
The Penetron cavity-fill method is an extremely effective solution to rising damp problems and situations where existing moisture and dampness needs to be dried out with minimal surface damage. The process consists of drilling angled holes into the moisture affected concrete structure and then filling them with a Penetron slurry. The final few inches of the holes would be capped off with Penetrcrete Mortar.
In this way, the active ingredients in the Penetron slurry is allowed to react with the moisture present in the concrete creating an insoluble crystalline structure within the concrete pores and capillary tracts. The concrete eventually becomes permanently sealed from within the structure as the Penetron reaction expands to seal it internally from further water and moisture intrusion from any direction. Over time, the system continues to improve as the crystals reach greater depths and increases in density, further eliminating any remaining moisture from the concrete.
The Penetron cavity-fill method is ideal for use on marine concrete structures, commercial and civil engineered structures, tunnels, structural walls, as preventative maintenance to at risk structures and any other application where rising damp or internal moisture problems needs to be addressed.

BASILICA
FULVIA-AEMILIA in Rome waterproofed by Penetron Cavity-fill
method |
|
Five years ago, Alda Fendi, of the Fendi fashion empire, bought a section of a Renaissance
palace in central Rome just yards away from the Column of Trajan. In the course of gutting
the space for an art gallery, laborers digging in the basement discovered architectural footings
of the Basilica Ulpia, a law court built by Emperor Trajan in 112 AD. Under the supervison of
Rome 's archeological Superintendency and after three years and 600,000 EU, the state acheologists recommended
that part of the basilica paving be restored and left visible. This meant digging through
to the ancient foundation which, when unearthed, was found to be subject to intrusion from groundwater.
The Penetron system was approved for use and the cavity fill method was used in one meter deep
holes drilled 10 - 15 cm in a ring at 600 around the foundations. Considering the age of the
concrete foundations, it was necessary to increase the free calcium for the most effective
application. This was accomplished by adding a calcium acetate solution before filling the
cavities with the Penetron slurry. The use of modern Penetron technology allowed the area to
become completely dried out allowing sections of this almost 2000 year old, historic structure
to be restored.

| Case
Study: Precast Concrete Plant |
|
 |
Fairfield, lowa, USA |
|
The customer was looking
for a way to enhance the performance of their precast
concrete septic and sewage units to reduce cracking
and provide a lasting waterproofing solution. After
a series of tests using both Penetron and Penetron
Admix, they made the decision to include Penetron
Admix as part of their normal concrete design mix.
During a quality control review, they identified
a few tanks that had developed some early stage
shrinkage cracks. One of the tanks was filled with
water and left for observation to confirm the benefits
of Penetron Admix in their concrete.
Initially, while there was no noticeable drop in
the water level, a number of leaks became apparent,
showing themselves as continuous, dripping leaks.
After three (3) days the leaks had been reduced
to a slow seepage with moisture creeping down the
face of the tank 3 ¨C 4 inches before evaporating.
At this time, crystals were plainly visible as they
began to fill in the cracks. After seven (7) days
all leaks had stopped completely as crystal growth
continued in the cracks until there was no moisture.
The customer also noted that the shrinkage cracks
that were also appearing in the precast concrete
lids of these tanks had also lessened through the
use of Penetron Admix.

Pendleton
Station ¨C South Carolina, USA |
|
Just
a few miles from Clemson University in South Carolina,
an academic residential and town center development
is being constructed. The Pendleton Station Development¡¯s
historical architecture will blend with the community
of Pendleton, focusing upon the typical South Carolina
Style.
The construction
techniques used at Pendleton Station are unrivaled in
the building industry. Insulating Concrete Forms (ICFs)
are being used in all fire walls, exterior walls, floors
and ceilings. The ICF construction technique consists
of expanded polystyrene blocks stacked around steel
rebar. Concrete is then poured inside the blocks giving
the unit strength and an outstanding insulating quality
(R52) and sound suppression capabilities. To further
raise the quality of the ICF construction, Penetron
Admix is being added to the concrete.
Penetron¡¯s
superior ability to lower the permeability of concrete
gives the ICF construction both waterproofing and corrosion
protection without incurring additional costs to over-excavate
for exterior applied systems while avoiding the additional
scheduling impacts that such systems bring. Penetron
Admix also provides other benefits such as increased
compressive strength of the concrete, freeze-thaw resistance
and greatly increased resistance to chloride ion penetration. |

Summerville
¡°Cannibal¡± Sludge Reduction Project- South Carolina, USA
|
|
Recently Earth Tech, Inc (an international provider
of global water management and transportation, engineering
and environmental services for municipal, government
and industrial clients) was selected to design the
new systems additions to the Summerville Commissioners
of Public Works (SCPW) Waste Water Treatment Facility.
In the design of this project, which includes a new
5.0 MGD screenings facility and RAS/IAS Pump station
|
|
|
among the many other additions
and . conversions,
Earth Tech,Inc
specified the use of Penetron Admix for the entire
structure of the new Pump Station Wet Well, base slab
of the Clarifier
Tank and the floor and retaining walls of the Screenings
Building. With these facility additions and changes,
the SCPW is estimated to realize an initial annual
savings of approximately $350,000 per year. |
