Techrevetment

Concrete mold mats made of geotextile are sewn into rolls with shaped compartments (pockets), structure and shape customized according to function and construction conditions; and spread on the surface to be protected, filled with small aggregate concrete.

Erosion prevention products for foundations, abutments, and bridge piers; dikes; irrigation canals, landfills and waste dumps. If there are no anti-erosion control measures, it can lead to a lot of costs for building maintenance, repair and repair. Erosion prevention for structures with high slopes, steep slopes, and high flow velocities.

• Product superiority:
• Protection against erosion throughout the life of the building.
• Maximum reduction in transportation costs and construction manpower
• Construction and good quality control in underwater construction conditions
• Very quick and simple construction, no maintenance required.

Geocell

Geocell is a geotechnical material that creates a 3D interaction between fill soil, geocell and cell geometry. . The geocell system maintains soil compaction, increasing the structural strength of the pavement layer.

The reinforcing function of geocells is to compact the soil horizontally and vertically, creating a beam effect and evenly distributing the load. The compacted soil inside can withstand the load, through horizontal stress on the cell wall, preventing the horizontal displacement of soil particles thereby increasing the vertical load acting on the reinforced structure.< /p>

Application:

• Traffic works: roadbed reinforcement, pavement structure reinforcement…
• Prevent erosion of slope surfaces and irrigation canals
• Retaining wall and slope stabilization reinforcement…

High-strength PET geogrid (ArmaLynk®)

High-strength PET geogrid (ArmaLynk®): is a solution for reinforcing the bottom of roadbeds built on soft soil or reinforcement applications Other land in the construction of airports, railways, road surfaces or heavy-duty foundations.

The geogrid is made from high-strength polyester (PET) fiber bundles assembled together and covered with a protective shell of high-strength polyethylene through oriented extrusion technology to form strips grid.

Vertical strips welded with horizontal strips also made of low shrinkage material together create a high-strength orthogonal geogrid.

ArmaLynk® can be manufactured in extremely wide roll widths with variable lengths and high stiffness edge strengths to optimize design and reduce material consumption during use.

Application in construction:

• The roadbed is on soft soil, stabilizing the construction foundation
• Sinkhole reinforcement repair
• Load transfer and roadbed reinforcement on pile reinforcement system
• Reinforce slopes and reinforced retaining walls
• Landfill expansion…

Composite draintube

Composite drainage mats are created by integrating a small drainage pipe system between two geotextile layers during the manufacturing process. This material is capable of providing filtration, separation and protection functions.

Product advantages:

• Drainage capacity does not change under the effect of embankment load
• No geotextile penetration, superior drainage efficiency
• Completely replace the drainage layer with crushed stone and install quickly.

Application:

+ Civil works: stadium drainage, basement, roof drainage…

+ Landfill: water/gas collection system

+ Transportation works: retaining wall drainage, horizontal drainage in soft soil reinforcement with PVD…

+ Mining and irrigation works: drainage in the body of cofferdams and dams

Photos of products and construction technology:

* Geogrid products, geocells, fiberglass mesh… are diverse in design and type, imported from advanced countries, ensuring quality and meeting requirements. for many construction items from traffic works, industrial infrastructure, environmental treatment. Besides, some products have been produced domestically and applied to many large projects.
