Water Containment & Hydraulic Engineering Solutions
Water infrastructure projects require reliable seepage control, erosion resistance, and long-term stability. Planetliner supplies geomembrane and geotextile systems for hydraulic and water-management applications, helping project owners reduce water loss, improve structural performance, and extend service life.The water containment geomembrane are normally 1mm 1.5mm thickness mostly.
Dams, Ponds and Storage Tanks
Typical challenges:
- seepage loss and water level instability
- subgrade settlement and differential movement
- puncture risks from stones and uneven ground
- UV exposure for exposed liners
Recommended lining system:The geomembrane dam liner and ditch liner can be HDPE liner, and the small reservoir can use LLDPE geomembrane.
- HDPE Geomembrane as primary impermeable barrier
- Nonwoven Geotextile as protection layer (underlay/overlay as needed)
Design notes engineers care about:
- thickness selection based on head pressure, subgrade condition, and design life
- slope stability and anchorage detail at crest/trench
- seam welding method and field testing plan
What we supply:
- Smooth / Textured geomembrane for ponds
- Protection geotextile rolls in multiple weights and widths
Stormwater Management and Flood Mitigation
Typical challenges:
- rapid inflow and overtopping risks
- erosion and scouring on slopes and channels
- temporary vs permanent detention requirements
- maintenance access and durability under cyclic wetting/drying
Recommended solutions (non-overlapping with other industries):
- Geomembrane where seepage control is required for basins or lined ponds
- Geotextile for filtration and separation, preventing soil migration and piping
- Erosion control concept: stabilize surface + manage flow velocity (project design driven)
Key selection factors:
- permeability and filtration performance (geotextile)
- UV exposure and cover conditions (geomembrane)
- installation sequence for wet environments
Rivers, Channels and Canals
Typical challenges:
- continuous seepage losses in canals
- bank erosion and slope instability
- sediment movement and soil piping
- construction constraints along long linear corridors
Recommended systems:
- Canal lining geomembrane to reduce seepage loss
- Geotextile underlay to protect liner and provide separation
- Reinforcement where needed: project may require stabilization measures depending on geotechnical design
Practical engineering notes:
- liner panel layout to reduce seams and improve installation efficiency
- anchorage and termination detail at banks/structures
- protection layer strategy (cover soil, concrete lining, or protective geotextile)
Coastal Protection and Reclamation
Typical challenges:
- tidal action, wave impact, and cyclic loading
- salt exposure and long-term durability requirements
- soft subgrade and settlement
- erosion control and separation in reclamation fills
Recommended systems:
- Geotextile for separation/filtration to prevent soil loss and maintain stability
- Geomembrane where containment/seepage barrier is specified in reclamation designs (project-specific)
Key selection factors:
- mechanical properties and survivability during installation
- long-term durability in saline and UV-exposed environments
- construction method and coverage (exposed vs covered)

FAQs
What is the popular thickness of the reservoir lagoon geomembrane liner?
Thickness depends on hydraulic head, subgrade condition, and design life. We recommend final thickness after reviewing project drawings and site conditions.
Do I need geotextile under geomembrane？
If subgrade has stones, sharp aggregates, or uneven surface, a protection geotextile layer is strongly recommended to reduce puncture risk.
How to control quality during installation？
Key items include seam welding procedure, field test plan, and proper anchorage/termination details.
