Waterproof Blanket for Fish Pond Slope Reinforcement

Construction Preparation

1. Material Inspection

• Verify the waterproof blanket's specifications and ensure it meets design requirements.

• Check for defects such as tears or holes, and prepare auxiliary materials like adhesives and fixing nails.

2. Tool Preparation

• Gather necessary tools, including scissors, measuring tape, trowels, hammers, and drills.

3. Site Clearing

• Remove debris, sharp objects, and weeds from the slope to ensure a smooth, clean surface.

• Level uneven areas and adjust the slope gradient to the recommended range (typically 1:1 to 1:1.5).

Waterproof Blanket Installation

1. Measurement and Cutting

• Measure the slope dimensions and cut the blanket to size, minimizing seams to reduce leakage risks.

• Leave a 10–15 cm overlap allowance on each edge for adjoining sections.

2. Installation Sequence

• Begin at the slope’s top and unroll the blanket downward, ensuring full contact with the surface.

• Align the blanket’s longitudinal direction with the slope gradient to facilitate drainage and prevent water scouring.

3. Securing the Blanket

• Fix the blanket with nails spaced 30–50 cm apart in a staggered pattern.

• Reduce spacing at edges and corners for enhanced stability.

• For soft soil, drive wooden stakes first, then attach the blanket to them.

Joining Waterproof Blankets

1. Overlap Method

• Overlap adjacent sheets by 10–15 cm. Clean the lower sheet’s edge, apply adhesive, and press the upper sheet firmly.

2. Sealing

• Apply waterproof sealant or tape over seams for long-term durability and water resistance.

Special Area Treatment

1. Corners (Inside & Outside)

• For external corners, cut the blanket at 45° angles before overlapping.

• For internal corners, add a 30–50 cm wide reinforcement layer before installing the blanket.

2. Pipe Penetrations

• Cut the blanket to fit around pipes, wrap it tightly, and seal with waterproof sealant or clamps.

Inspection and Acceptance

1. Visual Inspection

• Ensure the blanket is smooth, wrinkle-free, and securely fastened. Verify seam integrity.

2. Leak Testing

• Conduct a water spray test or fill the pond to check for leaks. Repair any issues immediately.

Post-Installation Protection

1. Avoid Mechanical Damage

• Prohibit heavy machinery or sharp objects on the blanket. Use protective boards if necessary.

2. Prevent Human Interference

• Post warning signs and assign supervisors to prevent unauthorized access or damage.

3. Environmental Protection

• Shield the blanket from prolonged UV exposure by covering it with shade cloth or soil.

A meticulously installed waterproof blanket ensures long-term slope stability and leak-free pond performance.
