The Problem

Traditional drainage layers made of gravel and sand require large volumes of material, heavy-duty transportation, and careful compaction. In landfills, highways, and dams, installation is slow and expensive, and it takes up valuable space in the cross-section of the project.

A Solução Techduto Geocomposite

Techduto Geocomposto completely replaces layers of gravel and sand with a three-dimensional HDPE geogrid core that promotes excellent flow of liquids and gases in all directions. Installed in rolls, it is 50% faster than conventional systems. The 2LG-F model adds an integrated waterproof membrane for dual functionality: drainage + water barrier.

Advantages & Differentiators

Why Geocomposto outperforms conventional systems

Replaces Brita and sand

Savings on materials, transportation, and labor at the construction site.

3D Center

Excellent flow of liquids and gases through the HDPE geogrid.

Quick Installation

Unroll and position, without compaction or layers of aggregate.

3 Models

1LG, 2LG, and 2LG-F for every type of project and need.

Total Resistance

It is resistant to chemical and biological agents and harsh soil conditions.

Environmental Protection

Prevents erosion and protects underground structures in a sustainable way.

Frequently Asked Questions

Dúvidas comuns sobre o Techduto Geocomposite — Surface Drainage

Yes. The three-dimensional core made of HDPE geogrid provides the same flow of liquids and gases as a layer of crushed stone, with the following advantages: faster installation, less material required, and no need for heavy-duty transport or compaction.
1LG (one layer of geotextile + geogrid) for filtration with drainage. 2LG (geotextile on both sides) for drainage with double filtration. 2LG-F (HDPE film + geogrid + geotextile) when an impermeable water barrier is required in addition to drainage.
Yes. Geocomposites are widely used in landfills for liquid and gas drainage, replacing layers of crushed stone with thinner layers that can be installed more quickly. Chemical resistance is essential in this environment.
Over 50 years. The HDPE used in the geogrid and geotextile is resistant to chemical and biological agents as well as harsh soil conditions, maintaining its drainage properties for decades.
The geocomposite is supplied in rolls. Simply unroll it onto the prepared surface and position it according to the design. No compaction is required. Seams are created by overlapping the rolls by at least 30 cm.
Yes. The 3D core made of HDPE geogrid maintains its structure under compression. For applications under pavements with heavy traffic, please consult our technical team to determine the appropriate model.
