Flooding’s Tabasco, Mexico
The state of Tabasco is located in the southeast of Mexico, from the coastal plain of the Gulf of Mexico to the mountains of northern Chiapas. Tabasco is one of the most populous states of the Mexico southeastern. Contributes to more than 1.3% of the national PIB, the second domestic producer of crude oil and natural gas after Campeche.
Due to the heavy rains that have occurred in Tabasco in the months of August and September of 2010, caused the flooding in most of the state's rivers, which pass their critical scales and consequently resulting in the overflow of the most of them. Because of these floods was affect 70% of the state and more than 130 000 peoples in 12 municipalities as was report by the governor of that state. In the same way, much of the municipal roads and highways are clogged by water, and several stretches of road have damage ranging from minor to serious. Tabasco is an area of Mexico that is affected every year by floods and storms of high intensity Since 2008, México has made PowerCem stabilization works of municipal roads and stretches of highway in Tabasco for the SCT (Minister of transport and communications) and the State Highway Board, where our leading product RoadCem has been used. Therefore, SCT and PCM has monitored the projects that have been involved, to know the result of the use of the products of PowerCem Technologies, found after severe flooding, the roads built with RoadCem still in excellent conditions, despite undercuts, wear and corrosion caused by high water levels and degrading agents.

Finishing the stabilization
Mixing of RoadCem and cement
The province of Noord-Brabant opened a tender for the extension of a roundabout, which is part of the N279, the link between Helmond and Den Bosch, due the amount of traffic. ARCADIS made calculations with the use of a variety of traffic models and this turned out to be the best solution with the best possible traffic flow. It was of great importance to the province of Noord-Brabant that the flow of traffic be guaranteed during implementation and to impede traffic as little as possible, let alone the fact that acceleration of traffic has to be created for the entire roundabout. By using the Nano based RoadCem the in-situ soil was used for the foundation, together with cement and fly ash. The stabilized layer had a high compressive strength and stiffness, with a high degree of flexibility. The unique combination of its fairly high flexibility and high compressive strength is achieved by using Nano based RoadCem technology developed by PowerCem Technologies. After the completion of the stabilization asphalt is applied and the roundabout is ready for use. During the entire road construction traffic flow was not affected and able to make use of the existing roundabout.

Curing RoadCem stabilization
RoadCem applied in basin Panama Canal
One of biggest projects in the world in 2012 is the capacity expansion of the Panama Canal. Substantial new infrastructure is required to enlarge the capacity of the canal. The construction of a new lock including new water basins, widening of the canal, strengthening of the embankments as well as new roads are part of the project. The Engineers responsible for the execution of the project have spotted the unique properties of the products of PowerCem Technologies, which have been successfully applied in other critical infrastructure constructions in various parts of the world. The successful track record of the technology has been the basis for working with PowerCem Technologies. One of the elements where PowerCem Technologies comes up as the preferred solution, is in the construction of an impermeable, strong and flexural slab that will be used in the water basin of the locks. The flexural strength from the PowerCem Technology provides for a better earth quake proof slab construction. For every lock there is a basin of 30.000m2.

Oil drill on RoadCem stabiliztion
Overview mixing process
Shell Canada’s Personnel was challenged with a location on Chinook Ridge Southwest of Grande Prairie, Alberta (Canada) where road bans were in effect and aggregate was in short supply, where rainfall caused the local clays to lose load bearing capacity and or where matting costs were prohibitive. CARES Ltd. introduced PowerCem™® Technologies and then Nano based stabilization process to Western Canada’s Oil and Gas Industry. The product RoadCem makes it possible to custom design mixes combined with fly ash, cement and in-situ soils of virtually any type eliminating the need to truck in or out any material significantly reducing the cost of road construction and environmental impacts. RoadCem construction is water impermeable so pollutions on top of the stabilization are not able to penetrate in the soil. A major concern for the Oil & Gas companies is what does our process do to the existing soils and how does it affect future reclamation as the responsibility resides with the lease or landholder to return the site to original state and use.

Urucu
2012
Roads
Here in the Amazon jungle, close to the Urucu River, there are drilling platforms operating. In the rainy season, the access and connecting roads to these platforms are impassable due to the washing away of road surfaces. And since RoadCem, a product from PowerCem Technologies, produces water-resistant infrastructure, Petrobas has chosen to utilize it for these roads. In other countries, the PowerCem technology has already proven to be able to produce road surfaces that are resistant to heavy rainfall and flooding. These results have been endorsed by UNESCO-IHE. Furthermore, the application of RoadCem also produces an environmentally friendly construction, because the stabilization of the in-situ subgrade, the rich clay, becomes possible with the addition of RoadCem. This means that few materials must be supplied or removed from the area. The constructed stabilization is durable, since the stabilization with RoadCem has a high load-bearing capacity and a high degree of flexibility. Due to the heavy rainfall in tropical areas, various measures, such as the covering of the roadway to be constructed, must be taken when paving roads in these areas. Using RoadCem makes construction times shorter and therefore the weather conditions can be more easily anticipated. This means that no tent must be erected over the roadway if a RoadCem stabilization is being laid. At the end of the rainy season, after extreme rainfall and a number of floods and under full loads, the stabilization built with RoadCem was intact. With the utilization of PowerCem technology, all environmental requirements were met and both a short construction time and a cost-savings of 20% were realized in comparison with the use of traditional methods. In the future these savings can increase to 40-50% as a result of low maintenance costs.

Athos- Vatopedi Monastery
2013
Roads
On the Holy Peninsula of Athos, PowerCem Greece had been re- quested to use theire technology for the acces road near the Va- topedi Monastery. This Monastery is one of the many Greek Or- thodox monasteries on the peninsula near the Holy Mountain of Athos.
Transport has to go always partly via ferries, what limits the amount of transportation volumes.
The Monastery has chosen to use RoadCem because its ability to stabilize soil with natural components in such a way that the in-situ Athos soil will be used. This leads to a road construction that is in harmony with the nature on the Holy Peninsula. First the road profile is levelled and big stones are removed, because the stabilization surface will also be the final surface. After the road is levelled and big stones are removed the road is mixed, seperatly, with RoadCem, water, and cement. After the mixing the treated soil is levelled and compacted. The final compaction is done with a tirecompactor for maximum compacting and a smooth surface. A few hours after finishing the compaction, the surface is cured during several days. By applying the PowerCem technology the monastery was able to cut costs 25% compared to traditional methods. By working with in-situ material there is only a low environmental load. The complete road structure is fully in harmony with the natural Environment.

Airport
Due to the increase in air traffic and the size of the airplanes utilizing the airport, one of the taxiways at the Brno Airport is being widened. The air traffic must continue on uninterrupted throughout the construction activities. This is one of the most important reasons for choosing the technology from PowerCem. After all, the PowerCem technology makes it possible to bind the in-situ material into a strong, flexible stabilization using the RoadCem product and cement. Using the in-situ material means that the supply and removal of construction materials is kept to a minimum and the amount of traffic caused by construction needs is drastically limited. This helps ensure that the safety of the air and construction traffic will not be endangered in any way. The in-situ subgrade, consisting of sandy clay with gravel and stones, is first profiled, which removes the largest stones. Then, RoadCem is added to the material and mixed with water after which a cement layer is applied which is then mixed together with the first mixture and water and transformed into a stabilization with high compression strength and elasticity. After the completion of this stabilization, a 5cm surface layer of asphalt is applied. The total construction time amounted to 24 hours. During the construction activities, the air traffic was not obstructed in any way; there were not even any flight delays at the time of construction. The utilization of the in-situ material not only resulted in time-savings, but a cost-saving of 25% in comparison with traditional construction methods was also achieved. Since the use of RoadCem produces high compression strength and a high degree of flexibility, the stabilization is easy to maintain, which can lead to a savings of between 25 and 60% in the future.
