When waterproofing is awarded, and who decides
Builtie times waterproofing from about 10% of the way through the build to about 35%, with the last realistic approach at about 45%. The general contractor awards waterproofing around the foundation and the building envelope; an envelope consultant or the architect often specifies the system.
Tap a stage. The highlighted stage is where waterproofing is typically awarded.
What to lead with: below-grade and envelope systems, warranty terms and inspection coordination.
Running the pipeline
Waterproofing work comes in waves that follow the permit record, so the pipeline that wins it starts from projects, not from a contact list. Track each project's stage, call the builder when it enters the window, and keep the foundation date, the specified system and the envelope consultant in the record. CRM for waterproofing contractors covers what to look for in a CRM built around that.
