North India’s First Jointless Floor delivered by LTFSPL

LTFSPL has been at the forefront of construction and renovation of industrial floor technology. An ideal floor would be perfectly flat and level and have no joints.

For making Jointless floor we have adopted large area construction method as against conventional long strip casting, by this method large floors up to several thousand square metres in area was laid in a continuous operation. Fixed forms were used only at the edges of the construction at intervals of typically 30 X 24 m. Concrete was discharged into the floor area and spread by laser Screed machines. Levels were controlled both manually using a target staff in conjunction with a laser level transmitter and by direct control of laser-guided spreading machines constructing free-movement areas,

By definition Jointless floors are floors constructed in large panels typically 50 m square without intermediate joints.

The word 'jointless' can be misleading, as there is a practical upper limit to the area of concrete that can be placed in a single continuous operation. No joints are sawn, but steel fibres incorporated into the concrete mix control the width and distribution of cracks caused by shrinkage. A benefit of jointless floors to the building user is the opportunity of having relatively large areas of floor with no joints.

Steel fibres were used in concrete to provide structural (load-bearing) capacity and for the control of shrinkage-induced cracking as against conventional Steel bars. 

Steel fibres for reinforcing concrete are manufactured from cold-drawn wire and  are used in grade or ground supported floors. Normally the preferred length is 60 mm, with aspect ratios of 80 (ratio of length to nominal diameter). In order to gain pull-out resistance fibres have hooked end profile.

Using Glued Steel Fibre Reinforced Concrete (SFRC) helped us with a time saving and providing cost efficient solution to our client. Being Multi dimensional reinforcement it offer following advantages:-

• Optimal Load bearing
• Optimal Crack control
• High fatigue resistance
• High impact resistance

Get more out of your slab

• Easier to maintain
• Longer lifespan
• Optimized Thickness
• Timesaving construction
• Better Performance 
• The ductile steel fibre floor with stands moderate deformations, minimizes curling of concrete slab.
• Easier  and more accurate installation.
• In 'jointless' slab construction, we used steel fibres at dosages in the order of 30-45 Kg/m3.
