What is English bond brickwork?
Brick formation - each bond consists of either headers or stretchers (NOT BOTH ON SAME BOND)
What would you do if you noted unauthorised occupation or alteration within the tenant’s demise?
1) Take photos
2) Check the lease
4) Inform tenant
3) Inform client / solicitors (If necessary) - Serve notice on breach
What is flemish bond brickwork?
Brick formation - headers and stretchers alternate each time
What is a solid wall?
External walls of a building that have no gaps (flemish) - two bricks wide
How can you tell if brick is solid or cavity from external inspection?
Solid wall = presence of headers
Cavity wall = absence of headers
What is a cavity wall?
Two layers of bricks with gaps in between of between 50-70cm

440mm X 215mm X 100mm
What is a purlin?
Horizontal beams in a roof used for structural support
Where does brickwork typically crack?
Along mortar joints as this is the weakest point
What is a roof truss?
Structure that consists of pieces of straight wood or steel joined together in triangular shapes to support the weight of the roof
What does horizontal line cracking indicate?
Cavity wall tie failure
What are the 4 types of cracking?
- Horizontal line
- Triangular
