PROJECT EXPERIENCE / TECHNICAL LIBRARY
Real roofs. Real constraints. Documented decisions.
These case studies focus on the technical reasoning behind the work: what was retained, what had to be repaired, how the build-up was coordinated and which details controlled the final result.
Ageing asbestos-cement roof: repair before replacement.
A repair-led strategy combining targeted void filling, flexible joint treatment, reinforced detailing, primer and a continuous liquid-applied protective finish.
Old torch-on roof: rebuild what matters beneath the membrane.
Approximately 2,500 m² of roof refurbishment with selective deck replacement, corrected falls, new outlets and a two-layer Börner SBS system.
One torch-safe system across apartment roofs and terraces.
A complete 630 m² warm-roof build-up connecting self-adhesive vapour control, PIR insulation, underlay, cap sheet and corner drainage details.
Two apartment blocks: H₂O refurbishment with safe access.
A 1,430 m² liquid refurbishment over existing torch-on membranes, coordinated with through-roof outlets and a permanent cable lifeline.
The membrane is documented as part of the decision—not as the whole story.
Each project connects roof condition, substrate work, drainage, system selection and critical interfaces. Product names remain useful, but only inside the complete technical context.
