Floor Defect Checking

Dear All,

I'm sharing with you how I measure the leveling of my floor tiles.

These are the tools I've used:

A LASER LEVEL

  A DIGITAL INCLINOMETER

A MEASURING TAPE 

Steps to take measurement

1)  Fnd the most leveled tile in the room. Based on my experience watching tilers at construction sites, tilers often use a leveled surface at the centre of the room as a reference point, set up a laser level on it, and start laying tiles in reference to the laser level. Using this concept, the most leveled tile will usually be the tile in the center of the room. However, use an inclinometer to double confirm this. A leveled tile will indicate the same angle irregardless of which position or direction you place it on the tile. If the angle is vastly different, try the inclinometer on the corner tiles of the room. The leveled surface that your tilers use could be at the corner of the room instead.
  
2) Establish the reference point and height. After finding the most leveled tile in the room, set up the laser level on it (my most leveled tile is in the centre of the room). The laser level will reflect a perfectly horizontal line, as seen on the wall. Place a mark under the laser level as an indicator, in the event you forget this reference point. Use your measuring tape to measure the distance between the floor and the laser line of the tile. Indicate the height on the tile as well, in case you forget the height. I've indicated the height on the tile below. This height is the ideal distance the tile should be from the laser line.

3)  Measure the height of all tiles with reference to the laser line. Now, repeat the steps of measuring the distance of the tile and the laser line for every tile in the room. A perfectly leveled floor will have tiles that are of the same distance with the laser line (in my example above, all my tiles should have a distance of 136mm from the laser line). The larger the distance the tile is from the laser line, the lower the tile; the smaller the distance the tile is from the laser line, the higher the tile is. An uneven floor will have varying tile heights from the laser line.

4) Use a torch light or spot light to confirm the unevenness. Once you are done measuring the heights place a torch light on the floor and shine it on the tiles. A shadow will appear if the tile is lower than the neighbouring tiles. A bright and lighted edge will appear if a tile is higher than its neighbouring tiles.

 

Why check leveling of tiles?

• It is unsightly and not nice to see
• It can cause a accumulation of water during cleaning of the floor with wet mop
• There is a possibility that you might cut your feet with the uneven edge that can be sharp
• Like the above reason you might just trip over the tile and fall
• YOU PAID A HANDSOME SUM OF MONEY FOR THE HOUSE AND POOR WORKMANSHIP IS JUST UNACCEPTABLE.
