HippoShield
HippoShield Geomembranes from Chemco are four layered, reinforced coated woven fabric specially engineered for effective water resource management in agriculture, aquaculture and industrial applications. Designed for water harvesting, industrial containment, groundwater storage, retention ponds and shrimp farming, these liners provide a strong, reliable and long-lasting solution for demanding environments. Manufactured with virgin grade polymers and high-density polyethylene coatings, HippoShield liners offer excellent toughness, durability and abrasion resistance. Their lightweight yet robust construction helps reduce transportation costs, minimise field seaming and simplify installation, resulting in significant savings in both time and labour. Available in 3.65m wide rolls, liners can also be factory-fabricated and transported directly to the work site for faster installation. The liners are offered in medium and heavy-weight fabric options, with various coating thicknesses and two colour choices to suit specific project requirements. Our woven coated geo fabrics come with a 3, 5, 7.5 and 10 years UV warranty depending on the [300, 500,750, 1000] micron of the materials and can be customised to suit your client’s needs. Built for easy installation and long service life, HippoShield delivers dependable performance, making them an efficient and cost-effective choice for containment and pond lining applications.

Installation
Land Selection
- Select land that is flat, stable and soft.
- Prefer a rectangular or square-shaped site for easier excavation and liner installation.
- Ensure the groundwater level is sufficiently low so that water does not rise from the ground during excavation, even after heavy rainfall.
- Begin excavation only after the land has been properly inspected and selected.
Excavation
- Use suitable earthmoving equipment, such as a Poclain or excavator, for excavation.
- Use the excavated soil to form and shape the pond slopes.
- Remove all stones, sharp objects, roots and other materials that may damage the pond liner.
- Ensure the pond base and slopes are properly shaped and compacted.
- Maintain the slope angle at 120 degrees or more, wherever possible, for better liner stability and ease of installation.
Laying the HIPPOSHIELD Pond Liner
- Prepare a cushioning layer of approximately 1.5 ft to 2 ft using soft soil on the base and slopes of the excavated pond.
- Lightly spray water on the cushioning layer to prevent the soil from loosening.
- Compact the soil using a roller or suitable compaction equipment.
- Ensure the surface is smooth, firm and free from stones, sharp objects, roots or any material that may puncture the liner.
- Open the HIPPOSHIELD fabric roll carefully and spread it according to the size and shape of the pond.
- Use trained and skilled operators while laying the liner to avoid stretching, folding, dragging or damaging the fabric.
- Use advanced hot-air gun technology or suitable seaming equipment for joining and sealing the liner.
- Ensure installation is carried out only by company-authorised or approved channel partner personnel.
- Check all seams at regular intervals, preferably at every one metre, to ensure proper sealing.
- After installation, have the entire pond inspected by an authorised technical engineer.
- Ensure the service quality report is reviewed and signed after inspection.
- During water filling, release excess fabric gradually from the pond edges to relieve stress on the liner.
- Properly anchor all excess fabric along the edges of the pond.
Protecting the HIPPOSHIELD Fabric
- After liner installation, install strong and durable metal fencing around all sides of the pond or farm area.
- Maintain a fence height of at least six feet to protect the pond from animals, people and external damage.
- Cover the outer slope of the pond with sand, gravel or suitable protective material to prevent soil erosion during heavy rains.
- Create strong access steps on the outside slope for safe movement.
- Provide a rough-surface escape patch on one inner slope of the pond so that any person or animal that accidentally falls in can climb out safely.
- Control the water flow rate while filling the pond to prevent sudden pressure on the liner and slopes.
- Place double or triple layers of protective fabric below the water filling pipe to prevent direct impact and damage to the HIPPOSHIELD liner.
Care While Filling Water
- Fill the pond gradually with water.
- Position the water filling pipe up to the back of the embankment.
- Ensure the pipe tip does not extend too far into the pond.
- Tie tubes, bags or sacks to the mouth of the pipe to reduce the force of water entering the pond.
- Avoid allowing water to fall directly onto the pond slope with strong force.
- Monitor the embankment carefully during filling to ensure the soft soil does not slide down.
- Continue checking the pond structure and liner during the filling process to avoid damage.
