Winwin EN1433 Polymer Concrete Kerb Drain D400 Series, Delivering Integrated Road Drainage Solutions

Winwin Block is pleased to announce the official launch of our EN1433 Polymer Concrete Kerb Drainage product line, with the flagship Winwin Resin Concrete Kerb Drain D400 now open for orders to engineering clients worldwide. This integrated drainage system combines kerb stone and linear drainage channels in one precast unit, specially designed for municipal roads, arterial highways, roundabouts, fire lanes and commercial parks with heavy traffic. It effectively addresses common drawbacks of traditional road drainage facilities, such as complicated installation, insufficient load-bearing capacity and easy cracking or corrosion.

1.Compliant with EN1433 European Standard, D400 Grade for Heavy Vehicle Loads

Our entire range of kerb drains strictly complies with the European drainage channel standard EN1433, passing comprehensive lab tests on load resistance, weather resistance and hydraulic performance. The flagship D400 model meets the 40-ton heavy-load standard, capable of withstanding long-term rolling by heavy trucks, fire engines and construction vehicles. We offer full load grades covering A15 for pedestrian zones, C250 for park roads and D400 for main traffic lanes, allowing customised matching solutions based on project traffic conditions.

Unlike conventional separate kerb stones and scattered catch basins, Winwin kerb drains feature an integrated precast structure that unites kerb barriers and drainage grooves into a single component. Optimised side drainage outlets rapidly collect surface rainwater, preventing road pooling, slippery surfaces and corrosive buildup of de-icing salts in winter, greatly improving road safety during rainy weather.

2. Polymer Concrete Material Offers Superior Durability & Corrosion Resistance

Each curb drain unit is integrally cast from high-performance polymer concrete, delivering remarkable advantages over ordinary cement concrete:

*Exceptional structural strength: Over 3 times the compressive strength of traditional concrete, resisting cracking, chipping and deformation under constant vehicle pressure.

*Complete corrosion resistance: Dense, stable molecular structure withstands road de-icing agents, oil stains, acid-base rainwater and coastal salt spray, making it suitable for chemical industrial zones and coastal cities.

*Self-cleaning smooth inner surface: Low friction coefficient enables natural flushing by rainwater, minimising sediment and leaf accumulation and lowering long-term maintenance frequency.

*Extended service life: Resistant to freeze-thaw cycles and UV ageing, with a design service life of over 30 years for outdoor use, cutting road renovation and replacement costs significantly.

3. Modular Precast Design Accelerates Construction Progress

All Winwin Kerb Drain units are standardised precast components manufactured in our factory with lightweight single-piece design. On-site installation eliminates formwork, cast-in-place pouring and secondary plastering. The interlocking joint design ensures high installation precision, achieving a maximum laying speed of 200 metres per day. Construction cycles are shortened by 60% compared with cast-in-place drainage trenches, saving costs on labour, machinery and project timelines.

A full set of matching accessories is supplied together, including D400 ductile iron load-bearing covers, catch basins, corner sections and reducer segments. One-stop integrated supply removes the hassle of sourcing parts from multiple suppliers and reduces cross-team coordination costs. Our kerb drains fit straight roads, roundabouts, curved carriageways, bus stops and auxiliary viaduct roads, with custom non-standard sizes available upon request.

4. Wide Application Scenarios Covering Full-Spectrum Urban Infrastructure

Winwin EN1433 polymer concrete kerb drain D400 series fits nearly all linear road drainage projects:

*Municipal arterial roads, urban expressways and roundabout intersections

*Fire lanes, heavy-duty parking lots and logistics park roadways

*Commercial complexes, high-speed railway stations, bus hubs and airport service roads

*Coastal landscape roads, industrial parks and sponge city renovation projects

*Main internal roads of residential communities and industrial estates

5. Winwin Specialises in Precast Drainage Systems with Standardised Infrastructure Products

As a professional manufacturer focusing on precast concrete and polymer concrete drainage components, Winwin Block bases all product R&D on the international EN1433 standard. We continuously upgrade our full drainage product portfolio, including kerb drains, linear drainage channels, slot drains, recessed manhole covers and catch basins. The launch of the D400 kerb drain completes our heavy-duty integrated road drainage product range, enabling us to provide one-stop standardised and customised drainage system solutions for municipal general contractors, design institutes and engineering contractors globally.

Moving forward, Winwin Block will keep optimising composite material formulas and precasting techniques to develop more lightweight, high-load and eco-friendly new drainage building materials. We aim to upgrade urban road infrastructure worldwide and deliver reliable, cost-effective products for sponge city and low-carbon infrastructure initiatives.
