Boasting almost a century of engineering heritage, Gatic continues to invest in research and development, ensuring a range of drainage solutions to meet the demands of our evolving modern infrastructure. This legacy underpins the Gatic Slotdrain range from Alumasc Water Management Solutions (AWMS); a versatile and high-performance range of surface water drainage channels engineered to meet the most demanding combinations of water capacity and load classification.
Designed for modern infrastructure, the Gatic Slotdrain system delivers trusted performance while maintaining a clean, unobtrusive surface finish. At the heart of the system is Slotdrain’s distinctive hexagonal profile, developed by Gatic to optimise hydraulic efficiency and structural strength. This design enables the channels to maintain exceptional flow rates regardless of rainfall intensity. Available in a wide range of sizes, with a comprehensive selection of accessories, the system offers complete design flexibility across multiple applications.
Gatic CastSlot is ideally suited to environments with constant, slow-moving traffic, such as supermarket car parks and logistics hubs. Engineered to withstand load classes up to F900, it integrates seamlessly into concrete, asphalt and block paving surfaces.
For more demanding conditions, Gatic UltraSlot is designed for heavily trafficked external concrete areas including airports, ports and industrial yards. Its configuration allows for increased concrete cover above the channel body, ensuring resilience under extreme loading. The system is manufactured with no moving or removeable parts, resulting in consistent, dependable performance, with minimal maintenance.
Both CastSlot and UltraSlot are available with a ‘treadsafe’ option, enhancing pedestrian safety in high footfall areas without compromising hydraulic performance.
For schemes where aesthetics are a priority, Gatic PaveSlot provides a discreet drainage solution for paved environments. Ideal for pedestrianised and public areas, it blends seamlessly with surrounding finishes, whilst also accommodating occasional vehicular loading.
For targeted drainage at building perimeters, FaçadeSlot effectively manages water at thresholds, walls and adjacent pavements. Its adaptable design allows installation along straight or curved elevations and can integrate directly with rainwater downpipes.
Gatic – Sustainable Solutions; Unrivalled Performance
Slotdrain systems are engineered with capacity in mind. Despite the minimal visible surface opening, intake performance exceeds typical rainfall demands. This makes the system well suited to sustainable urban drainage schemes (SuDS), where attenuation, storage and controlled flow are critical considerations as part of overall water management strategy.
Manufactured from pre-galvanised sheet steel, Slotdrain units are robust and resistant to damage during transport, installation and operation, helping to reduce whole-life costs. Options in stainless steel are also available for more aggressive environments.
Channel widths range from 100mm to 600mm, with the largest units offering storage capacities of up to 405 litres per metre. FaçadeSlot is available in 50mm, 75mm and 115mm widths.
Additional benefits include rapid installation, high strength-to-weight ratio, impact resistance, low maintenance requirements and tamper-resistant designs with no moving parts.
A comprehensive range of grates and covers is available to suit every conceivable system design, supplied with locking bolts for additional safety and security.
Both CastSlot and UltraSlot carry a verified Environmental Product Declaration (EPD) in accordance with EN 15804+A2 & ISO 14025 / ISO 21930.
