Is considered a very low permeability liner made out of synthetic material. Is regularly used for the containment of hazardous liquids that can contaminate the ground or surrounding structures if not correctly contained.

• a. Geo Membranes

• b. Geo Nets

• c. Geo Textiles

• d. Geo Composites

Works to prevent intermixing of sub-base soils with granular layers and help filter surface water to prevent stones and soil particles from passing and migrating into the sub-base. In environmental applications they are used as a protective cushion under or above geomembrane liners to prevent the risk of puncturing from coarse aggregate rock.

• a. Geo Cells
• b. Geo Nets
• c. Geo Textiles
• d. Geo Composites

Consists of a combination of one or more geosynthetics, specifically a geogrid, a geotextile, a geomembrane, and/or a geonet, with another material. Are used primarily for applications requiring separation, filtration, reinforcement, and drainage.

• a. Geo Membranes
• b. Geo Nets
• c. Geo Textiles
• d. Geo Composites

Is made of a new type of high strength geosynthetics, which is popular with both domestic and abroad, in accordance with GB/T 19274-2003 implementation of the standards, which welding the strengthened HDPE sheets by the high-power ultrasonic and forming to be a structure of threedimensional reticular formation

• a. Geo Synthetics
• b. Geo Nets
• c. Geo Cells
• d. Geo Composites

Is a geosynthetic material consisting of integrally connected parallel sets of ribs overlying similar sets at various angles for in-plane drainage of liquids or gases.8 gallons a. Geo Synthetics.

• a. Geo Synthetics
• b. Geo Nets
• c. Geo Cells
• d. Geo Composites

A dark brown to black cementitious material, solid or semi solid, composed of bitumen which occur in nature but are obtained artificially in refining petroleum and which when mixed with graded aggregates is used as paving material by placing, shaping and compacting while hot over a prepared base.

• a. Cold Mix Asphalt
• b. Asphaltic Macadam
• c. Hot Mix Asphalt
• d. Asphalt Overlay

When one or more courses or layers of asphalt, as an asphalt levelling course made of an asphalt and aggregate mixture of variable thickness to correct the contour of existing surface, are placed on existing pavement.

• a. Cold Mix Asphalt
• b. Asphaltic Macadam
• c. Hot Mix Asphalt
• d. Asphalt Overlay

Asphaltic concrete prepared with a relatively light and slow-curing asphalt, placed over a prepared surface without heat; hardens to a state that is less firm and durable than hot-mix asphaltic concrete.

• a. Cold Mix Asphalt
• b. Asphaltic Macadam
• c. Hot Mix Asphalt
• d. Macadam Road

Formed by grading and compacting layers of crushed stone or gravel, then binding the top layer with asphalt to stabilize the stone, provide a smoother surface and seal against water penetration.

• c. Hot Mix Asphalt
• d. Macadam Road

A type of road construction pioneered by JOHN LOUDON MC ADAM in 1820.
