Overview

The IS0412-65 -85 all-concrete pontoon is a heavy, low-motion floating structure designed for use as main marina walkways, berthing platforms and high-load zones in semi-sheltered to open-water environments. Its reinforced concrete shell with internal foam-core buoyancy provides long service life, predictable dynamic behaviour and flexibility for modular marina layouts.

Key Dimensions & Physical Properties

• Length: 12.0 m
• Width (clear): 4.0 m
• Width (including fender): approx. 4.25 m
• Heights available: 1.20 m / 1.40 m / 1.60 m
• Typical weight (1.6 m unit): approx. 33.5 tons
• Typical freeboard (1.6 m unit): approx. 0.85 m
• Buoyancy capacity: approx. 500 kg/m²
• Pontoon type: All-concrete, foam-core

Structural & Performance Characteristics

• Heavy reinforced concrete construction yields very low motion response suitable for pedestrian comfort and berthing operations
• High mass provides inherent damping and improved wave-dampening behaviour
• Suitable for main walkways, fingers and high-load marina zones
• Designed for a 30+ year service life in marine environments with appropriate maintenance

Materials & Construction

• Concrete grade: C40/50, specified for marine exposure classes XS2 / XS3
• Air-entrained mix with low water–cement ratio for durability
• Reinforcement steel: Grade 500, hot-dip galvanized where specified
• Internal buoyancy: high-density foam (≥60 kPa)
• Cast-in metal components supplied in stainless steel or hot-dip galvanized steel

Integrated Systems & Fittings

• Stainless steel cleats (10-ton rating)
• Fender connection sleeves cast into pontoon walls
• Pad-eyes at corners for mooring and anchoring
• Heavy-duty pontoon-to-pontoon connector boxes
• Integrated service ducts for electricity and water distribution
• Lifting sockets (M40) for installation and handling
