Dry and Wet Risers

Ventro provides a full range of fire safety services, ensuring a cohesive approach to fire safety within your building. Our multi-skilled teams guarantee that no fire safety stone is left unturned, leaving our clients with complete peace of mind.


Dry risers are installed in buildings usually over 18 metres where the fire brigade have restricted access to water. These systems should be maintained annually to ensure this water will deliver when needed.

Risers supply emergency services with a supply of water throughout a building in the event of a fire. Dry risers are a requirement of building regulations in buildings above 18 meters in height or taller, they are also commonly used in building with compartmentation issues or buildings with limited access for the fire brigade. The external inlet, pipework and internal outlets should all meet BS 5041, BS 5306, BS 9990, and Building Approval Regulations. Wet risers are often found in buildings 50 meters in height and above. Wet risers are constantly fueled with water in order to provide sufficient levels of water to protect against fires on all floors. Risers should be regularly inspected and maintained to guarantee optimal performance should a fire arise.

Our Approach

Ventro’s unique approach adopts a 3-step cycle to establish that our clients are proactively tackling fire-safety by ensuring buildings are not only brought up to compliance but kept that way. The 3-Step Approach includes our detailed 5-yearly Healthchecks, Remedial and Installation Planned Programmes of Works, and ongoing Regulatory Routine Maintenance Contracts.


The Healthcheck is an extended survey of the buildings to diagnose the issues within a building. We recommend that a Healthcheck is carried out at the beginning of engagement with ourselves and subsequently re-visited every 5-years as an extended review of the building in conjunction with our maintenance contract; to ensure our clients are keeping ahead of the curve with the most up-to-date solutions in an ever-changing regulatory environment.


Ventro provides an end-to-end project management service for all fire safety and regeneration projects, including the project, technical, site, and resident liaison aspects, ensuring that any remedial works required are carried out seamlessly and in a hassle-free manner for the client. Inclusive of specification, design, waste removal, supply and installation to provide the full turn-key solution to your project.


Following diagnosis and remediation, it is key that ongoing maintenance of all fire safety systems is proactively and routinely kept up-to-date to guarantee compliance requirements are met and ensure the safety of building users and longevity of installations. These are complemented every 5 years by an extended Healthcheck as described above to ensure total peace of mind.
