What is a waterproofing quantity surveyor?

A waterproofing quantity surveyor specialises in cost planning, takeoffs, and project management for waterproofing works in construction. They prepare accurate system-specific quantities, tender documents, and cost plans that help contractors and developers control budget and reduce risk on waterproofing projects.

The Common Industry Problem

One of the biggest issues in waterproofing projects is not always poor installation - it’s poor scope clarity.

A detail may exist in one drawing but not another. A supplier specification may assume a termination method that was never measured. A builder may expect inclusions that the subcontractor never priced. Everyone thinks the other party allowed for it. That’s where projects begin drifting into disputes, rushed variations, and lost margin.

Why This Happens So Often

Waterproofing sits between multiple trades, consultants, suppliers, and construction stages. Unlike structural concrete or framing, waterproofing systems often rely heavily on detailing, sequencing, and interpretation.

Small scope gaps can include:

Upstands not measured
Membrane overlaps ignored
Temporary protection omitted
Internal gutters missed
Substrate preparation underestimated
Flashings assumed but undocumented

Individually these may seem minor. Combined, they create major cost exposure.

The QS Perspective

A waterproofing-focused QS doesn’t just measure areas. They review intent, interfaces, detailing risks, and supplier-specific requirements before pricing leaves the business.

This creates:

Clearer tenders
Better variation protection
Reduced disputes
More confidence during procurement
Stronger communication between builder and applicator

Final Thought

Most waterproofing losses happen before installation begins. The businesses protecting their margins today are the ones investing in scope clarity early - not trying to recover costs later.
