What this sheet is for

Show a surveyor or insurer whether a crack is growing or only moving with the seasons. The readings are taken the same way every time, so they can be compared.

Who it is for

Homeowners, landlords and tenants watching a crack in a wall or foundation, before or while a surveyor is involved.

How to use it

  1. Number each crack on the wall beside it and describe it once in the register: where, which way it runs, its length and the marker fitted.
  2. Mark the point you measure at and use the same tool each time.
  3. At each reading, write the width and length, the season and recent weather, and any doors or windows sticking.
  4. Photograph the crack with the gauge or a ruler in shot and write the photo reference.
  5. Record who you told, and their reference, on page one.

What is on the sheet

2 pages, in this order:

Page 1

Printed under the title: Each crack numbered and described once, then its width and length measured at the same marked point over the months, with the season and a photo, for a surveyor or insurer to read.

Readings, not a verdict. No crack widths or damage categories are printed. Mark the ends of each crack and the point you measure at, use the same tool every time, and photograph it with the gauge or a ruler in shot. What the readings mean is for a surveyor or structural engineer to judge.

Questions

Why does the sheet not say what crack width is serious?

Because it is not a judgement a printed sheet should make: the width is one of several things a surveyor or structural engineer weighs, alongside the crack's shape, place and history. The sheet gives them a clean run of readings to judge from.

Why record the season and the weather?

Because many cracks open and close a little as the ground and the building wet and dry through the year. Readings with the season beside them make that movement easier to tell apart from a crack that is steadily getting wider.
