Ensuring rain leakage protection Asphalt Waterproofing by Shosekikako

No building is completely immune to the risk of rain leakage.
Even the slightest leakage of rainwater can cause a building to deteriorate and decay.
We manufacture, sell, and install asphalt waterproofing materials
to prevent natural disasters caused by weather to ensure safety for people.

Waterproof

Shosekikako, part of the Idemitsu Group, can offer robust waterproofing!
Asphalt waterproofing and modified asphalt waterproofing with excellent watertightness and durability

Waterproofing prevents water from getting into buildings.
Waterproofing has been available in Japan for more than a century, and is said to have started with asphalt waterproofing.
Currently, waterproofing work is carried out using various materials such as urethane rubber and sheets, but in recent years, with the frequent occurrence of typhoons, torrential rains, and other massive natural disasters, asphalt waterproofing is once again attracting notice due to its excellent watertightness and durability.
Having been the primary method of waterproofing for many years, asphalt waterproofing has become capable of handling all sorts of conditions through technical improvements.
Modified asphalt waterproofing was developed in response to the locations it is applied to, the times, and the environment.

Waterproofing of Buildings

Ensuring comfortable spaces!
Suppresses building corrosion and concrete deterioration by water.

Buildings are always impacted by outside elements, especially roofs and balconies, open corridors, eaves, and external stairs. No matter how good a building is, if it is not properly waterproofed, water in the form of rain or snow can enter the building through cracks, etc., resulting in water leaks that can adversely affect the structure of the building and contribute to the aging of the building itself. In order to prevent water leakage, the roof and walls must be waterproofed. A building that is properly waterproofed can reduce water corrosion and concrete deterioration and can extend the life of the building.

Waterproofing for Civil Engineering

Ensuring superior durability
Waterproofing supports the foundation of urban functions. It prevents water from getting into the internal structures of roads and bridges.

Waterproofing plays a vital role in civil engineering by keeping water from getting into the floorboards and other parts of the frame. For example, bridges made from concrete or steel are paved.
However, water may seep through the pavement and corrode and degrade the concrete rebar and steel floor slabs inside. A waterproof layer is therefore installed between the slab and the pavement to prevent seepage of water in order to protect the bridge from rust and allow the bridge to be used safely for an extended period of time.
In this way, waterproofing for civil engineering projects aims to realize a sustainable society by extending the service life of social assets.
