Retaining Wall & Drainage Construction

At SEA Construction Sdn Bhd, we deliver full-scale retaining wall and drainage construction — from earthwork and structural support to complete stormwater and site drainage systems. With nearly 30 years of combined experience, we build industrial-grade solutions that protect your land, prevent erosion, and keep operations safe, dry, and uninterrupted.

Retaining and drainage works are not just “supporting” tasks — they are critical to the safety and performance of any industrial site. Operators face challenges such as:

• Steep or uneven terrain requiring strong, engineered earth-retaining solutions
• Soil movement, erosion, and slope instability that can threaten buildings and roads
• Heavy industrial loads near boundaries needing high-strength retaining structures
• Poor water flow management leading to flooding, ponding, or sub-base failure
• Strict civil engineering, safety, and environmental compliance requirements
• Drainage detailing that must integrate with utilities, roads, and site layout
• Tight construction timelines to avoid disrupting ongoing operations

A proper retaining wall and drainage system must be structurally sound, hydraulic-efficient, and built for long-term resilience — not just installed and hoped for the best.
