MEXICO – Durable Waterpoofing solution in the Large Millimeter Telescope.

Project Description

The Large Millimeter Telescope is the world’s largest single-aperture telescope in its frequency range. It’s a joint venture between Mexico and the USA and has been built to further our understanding of the universe and the world around us!

Project Requirements

Our partners at Alchimica Mexico were recently involved with the project to waterproof the roofs on the site. The telescope is located on top of Sierra Negra, the fifth highest point in Mexico and 4,600 meters above sea level. Given the altitude the weather can prove a problem with high winds and even snow a real possibility up there. The HYPERDESMO® liquid waterproofing system was applied to the buildings to offer waterproofing and guarantee their durable performance even in the harshest weather conditions.

ALCHIMICA SOLUTIONS

With excellence resistance to cold, the HYPERDESMO® SYSTEM remains elastic even at -40 ° C but also the system holds an excellent thermal resistance, the product never turns soft with maximum service temperature at 80^oC and maximum shock temperature at 200^oC. In addition HYPERDESMO® holds excellent mechanical properties, high tensile and tear strength that makes it the best solution for durable projects.

Qatar – Exposed Metal roof waterproofing and protection system in the international media communication network.

Project Description

This complex application installed in the 3.200 m² roof of one of the most famous international media communication network in Doha. In an area that extreme climatic conditions occur such as high temperatures, high moisture and humidity levels, especially in the autumn period, and sandstorms which constantly push the construction materials to their operating limits especially on roofs. In addition, during heavy rains there is always the risk of unwanted water infiltration and humidity to cause considerable damage and corrosion to the metal roofs.

Project Requirements

As water and sunlight resistance are detrimental to the durability of coatings used on metal roofs, it is paramount for such project to fulfill high demands by close monitoring for highly detailed development and completion.

For the waterproofing of the metal roofs in this project, ALCHIMICA’s exposed metal roof system based on the HYPERDESMO® System was used. In this project, weathering steadily had damaged the large units of the metal roof parts and especially the cut edges causing the removal of the protective coatings and revealing the bare metal core to further corrosion. The project itself required specific requirements due to the complexities on the exposed metal roof and the corrosion problems that have been caused to the gutters and details.

ALCHIMICA SOLUTIONS

For this system, MICROSEALER-50, the low viscosity polyurethane-based primer, was used for the priming of the substrate and for the protection of the metallic roof joints and cut edges. HYPERSEAL®-EXPERT-150 was used for sealing the inner angles and gutters while reinforcement with GEOTEXTILE-50 was undertaken where needed for better future cracks protection. The HYPERDESMO^®-CLASSIC was used as the main waterproofing membrane of the system and finally HYPERDESMO®-ADY-E finished the build-up system for color stability and UV protection.

PRIMER: MICROSEALER – 50

SEALANT: HYPERSEAL®-EXPERT-150

ADDITIONAL MATERIAL: GEOTEXTILE-50

MAIN MEMBRANE: HYPERDESMO^®-CLASSIC

TOP COAT: HYPERDESMO®-ADY-E

Qatar – Exposed concrete roof waterproofing and protection system in the international media communication network.

Project Description

This complex application installed in the 3.200 m² roof of one of the most famous international media communication network conglomerates in Doha. Doha is a country that extreme climatic conditions occur such as high temperatures and sandstorms which constantly push the construction materials to their operating limits especially on roof areas. In addition, when heavy rains come there is always the risk of unwanted water infiltration which can cause considerable damage to the substrates and hence concrete corrosion.

In this project the building had been equipped with massive air-conditioning units installed in the roof making it a complex application.

Project Requirements

As water and sunlight resistance are detrimental to the durability of coatings used on flat roofs the importance of this project set high demands and close monitoring for high detailed development and completion.

ALCHIMICA with its global experience in waterproofing and sealing was able to provide assistance in every phase of the project, proposing the right products and systems based on the technical specifications, advising at the same time on the application methods for saving time and costs. The project itself required specific requirements due to the complexities on the exposed concrete roof and its details. That was why the designers needed a reliable system for a durable solution. ALCHIMICA considered all the technical and environmental impacts of the system in order to increase the durability and sustainability of the building and guarantee the high performance of the roof for years to come.

The suggested liquid applied waterproofing concrete roof system and application method for this specific project had to deal with the complex roof shapes which were formed from the air-conditioning units, pipe supports and antennas.

ALCHIMICA SOLUTIONS

Taking into consideration the complex roof but also the Qatar climate conditions, our HYPERDESMO® exposed concrete roof waterproofing system was selected and applied successfully, covering the total surface of 580 m2. The system included the priming of the surface with the GEODESMO-50 and also the sealing of the roof joints with the HYPERSEAL^®polyurethane technology sealants, while the certified HYPERDESMO® waterproofing membrane applied in 3 coats. The versatility and ease of application of our waterproofing system allowed the safe and easy treatment of the complex roof shapes and installations such as air-conditioning units, pipe supports, antennas.

As a final step, the HYPERDESMO® ADY-E high aliphatic reflective top-coat was used to ensure the durability of the system and the reduction of the building’s energy costs.

Roof waterproofing in Park View Erbil in IRAQ

Park View is one of the most prestigious projects in Arbil that is located on the airport road in front of Dream city and close to Erbil International airport. The project consists of 12 buildings which have been constructed in a circular form except from the ”Dream” building that it is placed in a rectangular way. Each building has 18 floors and offers spectacular view.

ALCHIMICA’s HYPERDESMO exposed concrete roof waterproofing system was chosen for the protection of this complex.

Exposed Concrete Roof waterproofing with reflecting materials in a residential block. Bangladesh

Bangladesh has a tropical monsoon climate with great seasonal variations in rainfall, high temperatures and high humidity. The monsoon rains cause water leakages that lead to corrosion problems in roofs, walls and basements both in residential and commercial buildings. In these conditions, structures tend to expose their limitations. Therefore, a waterproofing application should meet special requirements and it should not only to be effective in preventing the ingress of water into the structure, but also to be durable.

In those climates, it is also essential the buildup of a waterproofing system to include reflecting materials in order to reflect sun rays and repel heat. In this way we can reduce the need for air conditioning units, save energy costs and minimizing heat gain inside the buildings.

The multicolor HYPERDESMO® System was applied successfully in the exposed concrete substrate of the residential block in Bangladesh providing water tightness, ponding water and UV resistance and offering long-term performance.

The materials used in the application:

Primers : Wide range of primers designed to work exceptionally with all our products and different kind of substrates, depending on the application and its needs.

HYPERSEAL^®-EXPERT-150 : The novel, certified low modulus, highly elastic, thixotropic expansion joint sealant.

HYPERDESMO^®-CLASSIC : The innovative, certified highly elastic waterproofing membrane with strong adhesion to many types of surfaces.

HYPERDESMO^®-ADY-E : The aliphatic one-component polyurethane fluid, with excellent mechanical, chemical, thermal, UV and natural element resistance properties.
