MULTIV SYSTEM

Product catalog summary

Overview

The MULTIV+ drainage system is engineered for pedestrian zones, commercial areas, and car parks accommodating all vehicle types. It builds on ULMA's previous drainage lines, emphasizing economy, low profile, rapid fastening, and flexible slope configurations including presloped, cascaded, and mixed slopes.

System Specifications and Variants

Available in multiple heights with load classes up to D400 per EN-1433 standard.
Channel widths include MULTIV+100 (100 mm), MULTIV+150 (150 mm), and MULTIV+200 (200 mm) internal widths.
Standard channel lengths are 1 meter, with optional 0.5 meter sections.
Materials: polymer concrete channels with galvanized steel or ductile iron edges; stainless steel options also offered.
Optimized V-shaped channel cross-section enhances hydraulic capacity and self-cleaning.
Suitable for cascade-type slopes and installations without longitudinal slope.

Key Features and Advantages

8-point fastening system: Ensures superior mechanical stability and even stress distribution across gratings and channels.
Rapidlock® boltless fastening: Allows quick, tool-free installation and maintenance, reducing labor costs and enabling retrofitting without channel replacement.
V-shaped channel design: Larger cross-section than traditional V-sections, improving drainage speed and capacity, especially under extreme flow conditions.
Non-slip gratings: Special geometry enhances grip and water absorption.
Vertical locking tabs: Prevent floating effects and simplify installation.
Prejoined sealing points: Facilitate easier seal installation.
Anti-shunt mechanism: Ensures perfect grating alignment and automatic adjustment.
Directional grooves: Channel water inward to increase intake efficiency.
EN 1433 compliance: Includes grooves, channel markings, and real thickness (2+2 mm) to prevent corrosion and ensure durability.

Load Classes and Applications

The system supports load classes up to D400, suitable for heavy traffic areas. For extremely heavy cross-drainage, the KOMPAQDRAIN® system is recommended.

Gratings and Accessories

Gratings available in multiple designs: heelproof slotted, longitudinal slotted, mesh, and single slot.
Materials for gratings include ductile iron, galvanized steel, stainless steel, and composite materials.
Rapidlock® system integrated into gratings with optional blocking screws for enhanced security.
Sump units with outlet diameters of 110, 160, and 200 mm designed for self-cleaning and low maintenance.
Step units (codes CER100 and CER150) facilitate installation on height changes with cascaded slopes.
End caps and connectors available for open and closed channel ends, compatible with various edge materials.

Technical Data Highlights

Channel lengths: 500 mm and 1000 mm sections.
Channel heights range from 80 mm to 370 mm depending on model.
Hydraulic sections vary from approximately 79 cm² to over 540 cm², with reference flow rates provided for design.
Weights vary by channel size and material, important for handling and installation planning.

Installation and Maintenance Recommendations

Rapidlock® fastening enables fast, tool-free installation and easy maintenance without replacing channels or gratings.
Multiple fastening options provide flexibility, including boltless and screw-fastened systems.
Channels feature male/female vertical and horizontal joints for easy alignment and connection.
Preformed vertical outlets simplify plumbing connections.
Suitable for installation without longitudinal slope or with cascaded slopes.
Self-cleaning V-shape design reduces maintenance needs.
End caps and connectors facilitate installation on height changes and slope transitions.

Materials and Components

Materials include galvanized steel, polymer concrete, ductile iron edges, and stainless steel options.
Channel types vary by code with different dimensions and outlet sizes.
End caps available in open and closed types with various edge materials.
Security locking system BLOQPRG18020 provides 8 locking units per channel for secure assembly.
