Welcome to our first edition in 2012.Even in the face of current global economic turbulence Penetron Systems continue to be in demand as evidenced by the growing number of prestigious projects around the globe, some of which you will find showcased below. The global trend towards focusing on and increasing concrete durability is definitely felt across a wide spectrum of projects on all continents as 3rd generation crystalline admixtures are in heavy demand – with Penetron Admix leading the charge and setting benchmarks other systems are measured up to.
But before business, let’s talk about fun: we report on an ambitious Penetron team in South Africa in a formidable mountain bike race.
Berg & Bush Race 2011: Team Penetron Attacks the Mountain
Rory Eidelman and Clive Leader at the Berg & Bush Race
Rated South Africa’s best stage race, the Berg & Bush Race fully lives up to its name. The three-day mountain-biking event from October 26-28, 2011 covered a total distance of 227.62 km (141 miles). Clive Leader and Rory Eidelman, the Team Penetron competitors (only pairs can race) were impressed with the course.
“The first day included a descent of thousands of meters from the top of the Drakensberg to the valleys of Kwazulu Natal over beaten off-road tracks,” explained Clive Leader, also Director at Penetron South Africa Pty. Ltd. “But that was only the beginning.”
The route went past the famous Kerkenberg Mountain, the challenging climb up the Bezuidenhout’s Pass, a historic Anglo Boer War battlefield and finally, a climb up Bullers Cross and down Puff Adder Pass through thick African bushland and a thrilling descent down Big Red Mountain to the finish line. Team Penetron finished 264th (out of 450 teams), a remarkable result as it was Clive’s first mountain bike race.
I only started training two months before the race,” adds Clive. “But next year we’re aiming to be under the first 100!”

Vista Bahia, Nordelta, Buenos Aires, Argentina
A new luxurious 200-unit condominium development in the Nordelta not far from Buenos Aires, the Vista Bahia has much to offer:
- Exclusive bay views
- Large outdoor swimming pool (20x8 m), heated indoor pool, solarium, gym, and sauna
- Scottish showers, a laundry, changing rooms and parking
Designed by Studio Santa Ana Architects and built by Shap S.A, the project was built in Nordelta, a swampy land with high groundwater levels. It was essential to protect the concrete walls directly exposed to ground water and against water pressure from the bayside.
Penetron Admix applied to the substructure (15,000m² basement floor area) provides sustainable protection and concrete durability.
Mediterranean Village Resorts, Paralia, Katarini, Greece
Built on the beautiful coastline of Paralia, Katerini in Northern Greece, Mediterranean Village is a 5-star hotel complex of exceptional quality and luxury.
Covering a total area of 45,000m², the facility includes several independent and partially connected buildings with exquisite architectural elements. The proximity to the Mediterranean Sea posed a risk to the reinforced concrete structure with basements one and two levels below ground and sea-level.
The main requirements for the protection of the concrete not only included a completely waterproof concrete protected from corrosion and chloride penetration, but also resistance to carbonation.
In order to achieve all of these requirements the project engineers in collaboration with the developer Lambrou S.A. Hotel Enterprises decided to use Penetron Admix for the protection of the concrete. The objective was to create a white tank structure – a structure that is in itself waterproof without the addition of any topical applied products such as membranes or cementitious coatings.
"We needed not only to protect the concrete from corrosion and chloride penetration, but also resistance to carbonation," says Marinos Tseregounis Head of the Technical Department at Penetron Hellas. "A white tank structure was created with Penetron Admix to eliminate the need for topical membranes or cementitious coatings."
Penetron Admix was added to fresh concrete (a total of 3,500m³) at the time of batching; all construction joints were treated with Penebar SW swellable-type waterstops (1,600m).
