Bostik helps overcome the flooring challenges of modular construction at a Derby secondary school, delivering a durable, high-performance solution on schedule.
When Saint Benedict Catholic Voluntary Academy in Derby required a flooring system for its new two-storey building, delivered by modular building specialist Algeco, Envira Floors Ltd turned to Bostik for technical support and a comprehensive product solution. The multi-million-pound project demanded a flooring approach that could address the unique challenges of modular construction whilst meeting the rigorous demands of an active educational environment. The new block brings together the academy’s science laboratories and teaching spaces, increasing the need for a safe, durable and easy-to- clean flooring solution.
JOINTS & MOISTURE MANAGEMENT
Modular construction offers significant advantages in speed and cost-efficiency, but it also presents distinct flooring challenges. At Saint Benedict’s Academy, Bostik’s technical team identified two primary concerns during their initial site assessment.
Moisture testing revealed a split condition across the building. The ground floor recorded elevated humidity levels requiring a surface-applied damp proof membrane, whilst the upper floor tested satisfactorily dry and did not require additional moisture protection.
The second challenge centred on the joints – the seams where individual modular units are bolted together. These joints,
measuring between 3mm and 6mm, are subject to vibration and slight lateral movement. Without proper treatment, they could telegraph through the floorcovering or compromise the integrity of the installation. A flexible, resilient solution was essential to accommodate this movement whilst maintaining a smooth, level surface.
˝The joints were a particular concern – we needed a solution that would remain stable over time.˝
“Modular builds move quickly, so we needed a flooring system that could keep pace with the programme whilst addressing the technical issues specific to this type of construction,” explained Emma Wilson, contracts director at Envira Floors Ltd. “The joints were a particular concern – we needed a solution that would remain stable over time.”
A COMPLETE SYSTEM APPROACH
Following a comprehensive site inspection and moisture assessment in accordance with British Standards, Bostik’s Technical Consultant specified a complete system solution tailored to the project’s requirements.
The first phase involved addressing the joints using Bostik GRIP X910 FILL & WOOD, a two-component resin-based primer and filler. This product’s high bond strength and inherent flexibility made it ideal for accommodating the slight movement at the
