TMS masonry standards

TMS standards cover masonry construction and inspection: unit and mortar type, joint tooling, reinforcement and grout placement, and the moisture details that decide whether a wall stays dry.

Adoption varies by jurisdiction — confirm the edition your authority having jurisdiction enforces before you run a walk against it.

What it covers

  • Unit, mortar and grout types
  • Reinforcement placement and grout lifts
  • Joint tooling and cleanliness
  • Flashing, weeps and moisture management

What the evidence looks like

  • Flashing, weeps and drainage plane photographed before the next course covers them.
  • Grout lifts documented per lift, not as one shot at the end.
  • Reinforcement position shown in the cell before grout goes in.
