Type C Waterproofing in Guildford – Paramedic Training facility
Products Used: Newton Membranes
Architect: Scott Brownrigg
Main Contractor: Barnwood Construction
As part of its growing BSc Paramedic Science programme, the University of Surrey needed a practical training space that could support immersive, real-world simulation. This requirement led to the transformation of a disused basement undercroft within a university hospital building into a dry, habitable environment suitable for the installation of cutting-edge audiovisual equipment and training pods.
Barnwood Construction led the wider refurbishment of the building, with architectural design by Scott Brownrigg. Advanced Preservations was appointed to carry out the waterproofing of the basement space, working in close collaboration with Newton Waterproofing Systems to deliver a reliable and fully compliant solution.
Understanding the Waterproofing Requirements
The undercroft structure, located below ground level, presented a number of waterproofing challenges. The university required three separate contained spaces, each of which needed to achieve Grade 3 protection under BS8102:2022 – meaning a completely dry internal environment with no tolerance for water ingress or damp conditions.
The specification had to accommodate ongoing use of sensitive equipment, frequent occupation by staff and students, and a high level of interior fit-out. It also had to be delivered in a way that integrated smoothly with the larger refurbishment programme, and without introducing unnecessary delays to construction sequencing.
Delivering the Waterproofing Solution
Following an in-depth assessment, we installed a Newton Type C cavity drain membrane system to all below-ground surfaces. The system is designed to manage any moisture ingress by redirecting water behind the membrane and discharging it via a controlled sump and pump arrangement. To provide complete resilience, we also installed components from the Newton Type A range, combining internal and external protection for a robust, layered solution.
To support water flow and drainage within the space, our team applied specialist levelling compounds across the floors, ensuring all surfaces were prepared to the required tolerances. The design allowed water to channel effectively towards the drainage system while maintaining a flat, even finish suitable for subsequent floor coverings.
All works were carried out in accordance with current waterproofing best practice, with full integration of the Newton system as specified by the architect and client team. Our waterproofing installation included pump commissioning and service access points to allow for long-term maintenance.
The Outcome: A Dry, Functional Space for Immersive Training
The finished spaces now benefit from a fully protected, structurally sound waterproofing system, creating the ideal conditions for the university’s immersive training environment. The rooms are now used for simulated emergency scenarios, with 3D visual projections and surround-sound systems replicating high-pressure situations such as roadside accidents and public emergencies.
This project demonstrates how thoughtful waterproofing can support the creation of highly specialised, functional environments, even in spaces that were once disused or unsuitable for occupation.
