Industrial Shrimp Aquaculture Pond Lining · Mekong Delta

What Pioneer Delivered

Not just a machine — a matched system, a trained crew on site, and after-sales backing end to end.

• An on-site survey of pond geometry, slopes and fittings with a substrate-preparation plan before any spray — so the liner bonds to a stable base and does not punch through.
• A single-source system — JYYJ-H-V8T machine and food-grade NSF/ANSI 61 polyurea matched, tuned and warranted together, not a sprayer and a material bought from three suppliers who blame each other.
• A spray crew trained to hold even 3 mm thickness across sloped banks and humid-climate gel timing — the hard part of polyurea is the operator, and we own that skill.
• Holiday-tested QA and a pond-by-pond schedule built around the customer's production cycle — ponds went back to brood-stocking in under 48 hours, keeping the harvest calendar intact.
• Ongoing remote support for ratio and climate tuning, plus easy re-order of the exact matched food-grade material — lining the next pond block is a phone call, not a new project.

Execution Process

1. 1 · Substrate Prep & Compaction

   Each pond bed and bank is shaped, mechanically compacted and overlaid with a geotextile underlayment to give the membrane a stable, puncture-resistant base. Slopes and inlet/outlet fittings are detailed so the polyurea can run seamless from floor to crest.

2. 2 · Machine Setup & Material Check

   The JYYJ-H-V8T high-pressure rig is brought to 36 MPa with heated hoses, and the food-grade NSF/ANSI 61 polyurea is verified on test panels for full cure and adhesion. Gel time is tuned for the humid Mekong Delta climate before lining the first pond.

3. 3 · Polyurea Spray Lining 3 mm

   Hand-spray 3 mm of food-grade pure polyurea over the prepared bed with the JYYJ-H-V8T at 36 MPa, building one seamless monolithic liner per pond with no welds or overlaps to leak. The few-second gel lets the crew coat sloped banks and detailed fittings in a single continuous pass.

4. 4 · Cure & Return to Stocking

   Polyurea is tack-free in seconds and water-ready fast; the liner is holiday-tested for pinholes before filling. Ponds are flushed and returned to brood-stocking within 48 hours, with no inert leaching to disturb pH, salinity or dissolved oxygen.
