Superior Siphonic
Performance
Redefining Roof Drainage Performance
In an era of increasingly volatile weather conditions, effective roof drainage is critical to the safety, longevity, and performance of modern buildings. HydroStorm® delivers engineered siphonic drainage systems designed to outperform conventional solutions under the most demanding rainfall scenarios.
Our systems operate by activating full-bore flow through controlled negative pressure, allowing rainwater to be evacuated rapidly and efficiently from roof surfaces. This advanced hydraulic principle enables exceptional flow capacity while minimising infrastructure requirements throughout the building.
Extreme Weather Demands Smarter Drainage
HydroStorm® combines intelligent engineering with practical efficiency – reducing pipe sizes, minimising vertical drops, and streamlining installation – resulting in faster project delivery and optimised construction costs.
Trusted by designers, engineers, and contractors, HydroStorm® provides dependable drainage solutions for commercial, industrial, and complex architectural environments.
Engineered Advantages
Architectural Freedom
Flexible system layouts support long horizontal runs and reduced pipe penetrations, enabling cleaner ceiling spaces and greater design.
Superior Capacity
Full-bore siphonic action ensures rapid water removal during peak rainfall events, protecting structures and roof assets.
Engineering-Led Design
Each system is supported by detailed hydraulic calculations and technical drawings, to meet the guidance set out in relevant Standards.
Reduced Build Costs
Fewer outlets, smaller pipe diameters, and shorter installation times deliver tangible savings across materials and labour.
Sustainable by Design
Lower material consumption and efficient water management support environmentally responsible construction practices.
