Waterproofing failures rarely start at handover.
Most begin much earlier - during documentation, coordination, and tender planning. For developers, waterproofing is often viewed as a specialist trade package handled later in the build. But the earlier waterproofing systems are coordinated, the smoother the project becomes.
Poorly coordinated waterproofing documentation can lead to:
Tender inconsistencies
Contractor assumptions
Delayed procurement
Site redesigns
Expensive remedial work
On larger commercial and high-end residential projects, even small waterproofing errors can create significant downstream costs.
Early QS and scope review helps identify:
Missing detailing
System coordination risks
Incomplete quantities
Supplier inconsistencies
Programme-sensitive areas
The goal isn’t just accurate pricing. It’s reducing uncertainty before construction begins.
AQUOSYNC supports developers, builders, and contractors with waterproofing-focused QS and project support designed to improve project clarity from day one.
