Nightingale Quarter Block E6

A system designed for performance, speed, and sustainability

Facing tight deadlines and complex technical requirements, Wavensmere Homes chose Axter to design and supply a high-performance flat roofing solution that could be installed quickly while ensuring long-term durability and reliability.

Axter’s Excel® warm roof system, featuring multi-layer Reinforced Bitumen Membranes (RBM), was selected for its proven robustness, ease of installation, and dependable performance. Wavensmere Homes required a solution backed by a comprehensive guarantee, with fast installation times and responsive technical support – all of which Axter delivered.

Systems in use

The specification included a tapered insulation scheme to ensure effective drainage compliant with BS6229:2018, alongside Broof(t4) fire certification.

Excel® also aligned with the project’s environmental goals. The finished roof will support solar PV panels and battery storage to capture and reuse clean energy, contributing to sustainable living for more than 1,000 new residents.

“It was critical to install a robust bituminous system capable of handling the additional load of the PV installation while fully complying with all necessary regulations,” explains Joe. “The Excel system met all performance criteria and proved to be the optimal solution.”

Adapting to client deadlines and weather conditions

The project timeline was particularly tight following the concrete slab pour in December 2024, with winter weather adding unpredictability. Axter’s Quality Assurance (QA) team responded swiftly, conducting moisture tests within three weeks to confirm that the slab was ready to accept the waterproofing system, which was earlier than the typical 28-day curing period.

“At Axter, we are flexible and responsive to both client deadlines and weather challenges,” explains Joe. “Our on-site QA support ensured the contractor could proceed safely and confidently, keeping the project on schedule.”

Full Quality Assurance and supply chain coordination

Throughout the project, Axter provided continuous QA support to maintain compliance with specifications and workmanship standards. The team also coordinated the supply chain to ensure the timely delivery of materials and bespoke items.

Collaborative design support from concept to completion

Working closely with Gould Singleton Architects, Axter supplied detailing packs and advised on bespoke solutions where needed. This collaborative approach ensured all detailing was fully compliant with British Standards and aligned with the building’s design intent.

“Our technical team acts as an extension of the architect’s design process,” says Joe. “We support from concept through to delivery, helping protect specification integrity and project success.”
