Built for masonry contractors

Every course counted.

Bondline is the field app that thinks like a mason. Daily reports in three taps, T&M signed on the phone, and labor cost per unit while the wall is still going up.

Where the money leaks

The wall gets built. The profit walks off the job.

Masonry runs on labor, extra work and paper. Most contractors find out what a job really cost after it is finished, when nothing can be fixed.

70%

Direct labor can be up to 70% of installed masonry cost, yet units per man-hour usually lives in a foreman's head.

5%

Up to 5% of paper T&M tickets go missing before they are billed.

Rhumbix

Bondline captures clean field data at the source, then turns it into cost per unit, signed extra work and reports nobody has to retype.

A foreman's day

Built for gloves, sunlight and no signal.

Scroll through one day on site. Every screen has big targets, picks from lists instead of typing, and saves on the phone first.

6:45 AM

The daily report starts itself.

Project, date, weather and yesterday's crew are already filled. Yes and no questions are big toggles. If something does not apply, it stays hidden.

  • Weather pulled from the job address
  • If/then rules show only what matters
  • Mason IQ catches missing details before submit
3:30 PM

Hours by cost code, in under two minutes.

Copy yesterday, adjust two numbers, done. Names come from the company list, so payroll never sees "Jose R." and "J Rodriguez" twice.

  • Add my crew in one tap
  • No worker on two jobs at the same hours
  • New hire? Added as pending, office approves
4:10 PM

Extra work, signed before the GC leaves.

Photos, hours and materials on a T&M tag, signed on the phone by the GC's super. The office has the PDF the same afternoon.

  • Signature with name, time and GPS
  • Locked after signing; edits keep history
  • Tracked until it is billed
4:12 PM

Report laid. Office already knows.

The PM gets a short summary of every report, issue and extra. The owner sees units laid against the estimate the same day, not at closeout.

  • Syncs the moment signal comes back
  • Review, approve or return with a note
  • Exports with no row caps

Synced
Everything on one job site

Your field app and your job costing, finally talking.

Everything a field app does today, built around masonry units, crews and cost codes. The office side replaces the separate job costing tool, so nobody types the same hours twice.

Smart forms that read like sentences

Rebuild every form you use today, then make them smarter. Rules show, hide, require or fill fields for you. One company field library keeps every project's data comparable.

If forecast low < 40°F then require the cold-weather checklist
If units laid < 50% of plan then require a delay reason
If T&M section is filled then require GC signature

Mason IQ

AI that knows a bond beam from a bond line.

Mason IQ works inside your forms and your data. It drafts, checks and explains. It never sends, signs or bills anything without a person approving it.

Talk, don't type

"Seis albañiles, ocho horas, terminamos el bond beam del segundo nivel."

Speak in English or Spanish. The report fills in for the office in English.

Catch it before submit

Crew 2 logged 3.1 units per man-hour. Their usual is 1.8. Did you mean 31 units or 310?
310. Fixed.

Flags numbers that do not look like your job, vague notes and missing photos while the foreman is still on site.

Ask your jobs

Which jobs are behind on CMU this week?
Two. Harbor Clinic is 14% under plan, mostly rain on Tuesday. Riverside School is 9% under with crew 3 short a tender.

Analytics

Know the job is slipping on Tuesday, not at closeout.

Because every form stores clean, typed fields, every report becomes a chart: units per man-hour, labor cost per unit, open T&M dollars, late reports. Owners see every job; PMs see theirs.

Projects, tasks, forms, plans and photos copy over. Run it again any time; nothing duplicates.

Monday

Pour

Foremen open the same jobs on their phones, with yesterday's crews already there.

Founding contractors

Help us build the app you wish you had.

We are onboarding a small group of masonry contractors this season. Founding contractors get hands-on setup, their forms rebuilt for them, a direct line to the people building it, and founding pricing that stays.
