This structure was more than 25 years old and in need of refurbishment, with the objective of realising at least a further 50 years of service life at a minimum.  There were several issues to overcome with high humidity, a salt environment, many deck areas susceptible to ponding and contaminants including jet fuel residue.  The existing deck areas and ramps were media blasted where possible and the remaining areas high pressure washed.  Any existing cracks over 2 mm width were epoxy filled.

Radcon Formula #7® called to the rescue of a new raised highway segment in Japan. The Number 2 Tomei Highway is a part of the busiest expressway in Japan, located west of Tokyo.

The first sections were opened as early as 1968 and today it covers more than 320 kilometers connecting Tokyo and Nagoya.

The newly erected raised segment, constructed by Shimizu Corporation, exhibited water leakage issues.

The contractor, Japan Highway Public Corporation, have used Radcon Formula #7® before and were aware of its faultless performance on structures subjected to thermal stress, carbonation and weight loading.

CLIENT:  Shimizu Corporation
APPLICATOR:  Kankyo Biken
AREA:  Bridge Deck

Radcrete Pacific’s distributor in Portugal was called on to waterproof the country's newest cultural landmark. No other product could achieve complete waterproofing without compromising the artistic quality of this amazing structure.


To build the Museum of Art and Archeology in the stunning Côa Valley, many factors had to be considered: topography, accessibility and the environment. The result is a museum installation within the landscape. The backdrop is the vast landscape of hills and valleys, the relationship with topography. At the highest point of land, this triangular body is stuck between two valleys (Valle de José Esteves and Vale do Forno), with the front facing the third meeting of the rivers Douro and Coa.

Constructed by WAYSS  & Freytag, a subsidiary oft he leading German building and civil contractors the Menara Kuala Lumpur telecommunications tower ist currently the tallest concrete tower in SE Asia and the third tallest telecommunications tower in the world.

The tower, standing 421 meters high, is located in the Bukit Nanas area of Kuala Lumpur. The total weight oft he tower ist some 100,000 tonnes  utilising 45,000 cubic meters of concrete,  5,300 tonnes  of reinforcements and 1,300 tonnes of structural steel.

The tower structure is divided into three basic sections – the Foundation Base will accomodate a theatre, amphitheatre, shops, fast food restaurant, souvenir shop etc. The Tower Shaft has 4 lifts and staircase. The Tower Head will be used for telecommunication purposes and also have an observation platform and revolving restaurant.
Green East Enterprise, our Malaysian distributors, applied Radcon Formula #7® to 750 square meters of Levels 9 & 10 of The Tower Head. These selections of concrete are exposed to high levels of UV light. Radcon Formula #7® was ideal in this application as the material, unlike normal coatings, will not deteriorate due to high UV exposure and frequent rain periods.

The New Kelani Bridge is one of the biggest infrastructure projects to be executed in Sri Lanka


Package 1 consisted of composite steel and concrete ramps, interchanges and bridges and Packaged 2 the extradosed bridge.  The location, climate and conditions as well as design life meant that bridge deck waterproofing was an important part of the overall structure to meet its durability requirements.  Normally membranes are the standard system for bridge decks however there was intense debate among the designers, consultants, contractors and waterproofing contractors on what was to be the most effective method.  The bridge deck concrete mix design was both robust and sophisticated using shrinkage reduction technology which is used extensively in Japan.  The final material decision criteria was based around safety, cost efficiency, speed, effectiveness, durability, technical performance and certifications and relevant previous experience. 

Local waterproofing contractor HE Engineering won the approval and application contract with Radcon Formula #7®, which is a proprietary biochemically modified silicate solution.  This material penetrates into the concrete pores, capillaries and cracks (up to 2mm) to form a Gel.  A clever part of this product is the biochemical component facilitates a part of the gel to mineralise to calcium carbonate over time to create a permanent waterproofing seal and also to reseal new hairline cracks that occur after application.  This material has been used extensively in the harsh tropical Asian climates on over 3,000 bridges and 5 million Sqm of bridge decks where high temperatures and heavy monsoon rain can create destructive vapour pressure below membranes which make them susceptible to delamination. Radcon Formula #7® dramatically lowers the risk of this happening. 

A key performance criteria was its hot asphalt compatibility. Radcon Formula #7® has been tested extensively in the laboratory and the field and there is no loss of effectiveness or bond loss to Hot Asphalt.  The fact that Radcon Formula #7® penetrates making it 100% trafficable also means there is no risk of damage to the waterproofing with the asphalting plant or any other machinery after application. 

The application speed and efficiency allowed HE Engineering complete the waterproofing application quicky even with intense QC procedures which greatly assisted the construction timetable and allowed the contractor to bring asphalting forward in the program which was disrupted by Covid related stoppages. 

The final result was effective long-term waterproofing done with speed and efficiency whist lowering overall risk.
