Reduced water loss and greater ground protection
GEOALISI supplies and installs geomembrane linings for conveyance canals, ditches, drains and slopes. The system creates a continuous barrier to reduce seepage, convey liquids in a controlled manner or protect an exposed surface.
Execution follows a project-approved solution. When no specification exists yet, we can review the available information and compare alternatives without replacing the hydraulic, geotechnical or structural design of the responsible professional.
The service is especially useful when a project must coordinate materials, installation and controls without splitting responsibility among multiple suppliers. Early definition of layers, anchoring, transitions and handover conditions helps anticipate interference with civil works, drainage and structures. The lining is therefore integrated into the schedule as a complete system rather than an isolated item.
What the contracted scope may include
- Review of drawings, profiles, specifications, sections and access.
- Supply of geomembrane, protective geotextile and specified components.
- Surface preparation when expressly included in the proposal.
- Panel deployment and joining, anchoring, edges, curves and changes in slope.
- Treatment of penetrations, structures, transitions and contracted repairs.
- Visual inspection, seam control and records defined for handover.
Where it applies and what defines the solution
It is used in irrigation or process canals, ditches, drains, cut or fill slopes and surfaces exposed to runoff. It can reduce water loss, control fluid contact with soil or protect a surface against deterioration.
Material, thickness, texture, protective layers and anchoring depend on the fluid, flow, slope, geometry, substrate, exposure and ground stability. These criteria must be defined or approved before execution.
How we work
- We define layers and anchoring according to slope and hydraulic conditions.
- We resolve transitions and interfaces to maintain continuity.
- We coordinate installation with flow conditions or the project schedule.
- We document execution according to the contracted scope.
Preguntas frecuentes
What problem does the lining solve?
It reduces seepage, conveys liquids in a controlled manner and protects canals or slopes exposed to water and erosion.
Does the service include surface preparation?
The proposal expressly defines the preparation performed by GEOALISI and the condition the project must provide.
What materials can be used?
Smooth or textured HDPE or LLDPE geomembranes, protective geotextiles and anchoring systems, according to the approved specification and project conditions.
Can you participate if the solution is not yet defined?
Yes. We can review lining alternatives and compatibility to guide the scope. The hydraulic, geotechnical or structural design must be approved by the responsible professional.
Do you need to line a canal or protect a slope?
Let’s discuss the project before seepage or deterioration constrains the work. We assess the appropriate lining and prepare a clear scope.
