1. Introduction

The Ubbink 1331960 Geotextile Felt is a high-quality protective layer designed for use as an underlay for pond liners.

This ensures the longevity and integrity of your pond system.

Key features include:

• Material: Durable, non-rotting synthetic material.
• Color: White.
• Dimensions: 5 x 2 meters (Length x Width).
• Density: 200 g/m², providing robust protection.

2. Setup and Installation

Proper installation of the geotextile felt is crucial for effective pond liner protection. Follow these steps carefully:

1. Prepare the Pond Bed:
   • Excavate the pond to the desired shape and depth.
   • Remove all sharp objects, stones, roots, and debris from the entire pond bed and sides.
   • Ensure the surface is as smooth and level as possible. Compact the soil if necessary to prevent settling.
2. Lay the Geotextile Felt:
   • Unroll the Ubbink geotextile felt over the prepared pond bed.
   • Carefully position the felt to cover the entire area where the pond liner will be placed, including the sides and shelves.
   • If using multiple pieces of felt (for larger ponds), ensure an overlap of at least 15-20 cm (6-8 inches) at all seams to provide continuous protection.
   • Smooth out any wrinkles or folds in the felt to ensure it lies flat against the pond bed.
3. Install the Pond Liner:
   • Once the geotextile felt is correctly laid, carefully place your pond liner over the felt.
   • Avoid dragging the liner directly over the felt to prevent shifting or damage to the felt layer.

3. Application and Function

The Ubbink Geotextile Felt serves as a critical barrier between the pond liner and the underlying soil. Its robust synthetic fibers distribute pressure and prevent sharp elements from puncturing the liner. This protective function is passive and continuous once installed.

Benefits of using this geotextile felt include:

• Puncture Protection: Shields the pond liner from stones, roots, and other sharp debris.
• Even Pressure Distribution: Helps to distribute the weight of water and pond elements evenly across the liner.
• Increased Liner Lifespan: Extends the life of your pond liner by preventing premature wear and tear.
• Chemical Resistance: Made from synthetic material that is resistant to rot and common soil chemicals.

4. Maintenance

Once installed beneath a pond liner, the Ubbink Geotextile Felt requires minimal direct maintenance. Its durable construction is designed for long-term performance in sub-surface conditions.

• Periodic Inspection: If the pond is drained for cleaning or repair, take the opportunity to visually inspect any exposed areas of the felt for tears or damage.
• Repair: In the unlikely event of damage to the felt, small tears can be repaired using appropriate geotextile repair tape or by placing an additional patch of felt over the damaged area before reinstalling the pond liner.
• Protection from UV: The felt is designed to be covered. Prolonged exposure to direct sunlight (UV radiation) can degrade synthetic materials over time. Ensure it remains fully covered by the pond liner.

5. Troubleshooting

While the geotextile felt is a protective component, issues related to pond liner integrity can sometimes arise. Here are some troubleshooting tips:

• Liner Leakage: If a pond liner develops a leak, it is essential to locate the source. The geotextile felt helps prevent punctures from below, but leaks can still occur due to external damage, poor liner seams, or aging liner material.
• Felt Shifting: Ensure the felt is laid smoothly and securely before placing the liner. If the felt shifts during liner installation, it may create uneven protection. Carefully reposition it.
• Inadequate Overlap: If multiple felt pieces are used and an insufficient overlap was provided, a weak point may exist. During any major pond renovation, verify overlaps.

For persistent issues, consult a professional pond builder or specialist.
