Floors

What is the function of a floor?

• To provide lateral restraint to external walls

• To resist moisture entering the building

• To support dead and imposed loads

• All of the above

Which type of floor construction is built off the soil?

• Solid ground floor

• Beam and block floor

• Suspended timber floor
  
  

• Concrete slab

What is the purpose of joist hangers in upper floor construction?

• To support the timbers and reduce the risk of rot
  
  

• To provide lateral restraint to external walls

• To improve fire resistance
  
  

• To increase sound resistance

What is the purpose of a DPM (damp proof membrane) in ground floor construction?

• To provide lateral restraint to external walls
  
  

• To improve fire resistance
  
  

• To resist moisture entering the building

• To increase sound resistance

Which type of floor construction uses concrete blocks and sleeper walls?
