  2. 2. FLOOR Structural component made to provide a level surface . It is a horizontal sanitary surface that supports the occupants of a building, furniture and equipment. STRUCTURE OF A FLOOR. The floor is divided into three components Sub base Base concrete Floor finish
  3. 3. Cleanliness- The flooring should be capable of being cleaned easily, and it should be non-absorbent. Resistance- Should have effective resistance against absorption of oil, grease etc. Durability - The flooring should have sufficient resistance to wear, temperature changes, disintegration with time and decay. Tiles, marble, terrazzo, concrete, mosaic etc. are considered to be of best types. SELECTION OF FLOORING MATERIAL
  4. 4. Hardness- It should be sufficiently hard to resist indentation marks, imprints etc. likely to be caused by shifting of furniture, equipments etc. Maintenance - Flooring material should require least maintenance, repairs can be done easily. Tiles, marble, terrazzo, concrete etc. require less maintenance. SELECTION OF FLOORING MATERIAL
  6. 6. STONE FLOORING There are following types of stone flooring – 1-marble flooring 2-granite flooring 3-kota stone flooring Marble flooring Marble flooring is commonly is provided in places of worship and in public buildings having rich specification.

  16. 16. Tiled Floors The usefulness of tiles as a flooring material is due to Their pleasant appearance. It eliminates the possibility of cracks. Quick execution of flooring Constructed from square, hexagonal or other shapes Made of clay ( pottery), cement concrete or terrazzo. Available in different sizes and thicknesses. Commonly used in residential houses, offices, schools, hospitals and other public buildings, for floor to be laid quickly.
  17. 17. BASE FOR TILE FLOORING Flooring may be laid on reasonably rigid base. Surface of the base shall be rough to form suitable key with bedding mortar. The base, about 35 to 50 mm below the level of the finished floor, to be properly graded and free from lose earth, dirt, dust and lumps.
  18. 18. LAYING OF TILES Laying of Bedding Mortar- For pre-finished ceramic tiles – the bedding mortar used for this has the cement and coarse sand ration of 1:4 For glazed earthenware tile -the bedding mortar used for this has the cement and coarse sand ration of 1:3 Quantity of water should be such that it gives the motar sufficient amount of plasticity and also makes the mortar workable. Average thickness of bedding mortar = 20 mm Thickness under the tile = not less than 10 mm. Allowed to harden for 12 to 24 hours. Before laying the tiles, neat cement slurry is spread over the bedding mortar
  19. 19. Preparing the bed for laying the tile
  20. 20. LAYING OF TILES Tiles are laid flat, gently pressed into the bedding mortar with the help of wooden mallet. Before laying the tiles, thin paste of cement is applied on their sides, over the entire perimeter surface Next day Joints between adjacent tiles are cleaned of loose mortar etc. to a depth of 5 mm, using wire brush Then grouted with cement slurry of the tile colour. The slurry is also applied over the flooring. Then curing is done for seven days In Vitrified ceramic tiles – wetting of the back surface before laying is adequate. In Glazed earthenware tiles - tiles are soaked in water for an hour before laying.
