Patent

Seismic base isolation foundation structure and seismic base isolation construction method using it
Patent No.: 5196059
Acquisition date: February 15, 2013

Examination certification

Reinforcement Earth Bag used in
Subsidence Suppression Foundation Method
Certificate No.: BL examination certificate-015
Seismic Damping Effect of Reinforced Earth bag
(T-BAGS laminate) ~Housing T-BAGS
Certificate No.: BL examination certificate-029

Shock absorption effect for buildings.

T-BAGS Seismic Base Isolation Method uses two, layered sand bags with a special sheet placed in between them under the floor and foundation.

In the event of an earthquake, the sand bags are able to freely slide and absorb the vibrations.

Concept of safe and secure T-BAGS base isolation method

Cannot be secured with “Will not damage / Will not collapse”.
We mush minimizing the impact of earthquakes to the lowest possible level.

Simple seismic base isolation construction method similar to sandbags

Frost-heaving countermeasure for freezer warehouse

T-BAGS act as a measure to prevent freezing of the ground beneath the freezer warehouse.
(When the ground freezes due to cold air, it will increase the volume of the soil, causing detrimental uplift effects on the building structure).

Demonstration of Frost-heaving countermeasure effectiveness

Verified the frost-heaving countermeasure effectiveness by temperature and air flow analysis.

Other usages of T-BAGS method

T-BAGS application in Vietnam

Strong domestic demand and the expansion of e-commerce are the main driving forces propelling the growth of the cold storage industry. However, the cold storage market in Vietnam is now in its nascent stage, with limited capacity that falls short of meeting the existing demand.

In addition, the complexity of the cold storage operating system requires higher investment capital and operating costs than conventional types of warehouses. Therefore, cold storage facilities invested in systematic design and construction, optimizing operating shall gain a competitive edge over traditional rivals and attract further investment from larger enterprises in the future.

T-BAGS construction method has outstanding advantages, including no need to arrange a ventilation system, helping to reduce maintenance costs for cold storage and optimize construction costs.
