Freeplan®
SFRC Jointless floors
Freeplan® jointless flooring is cast in large areas using steel fibre reinforced concrete (SFRC) but without the need for induced contraction joints.*
“An ideal floor would be perfectly flat, level and have no joints.”
Concrete Society TR34; third edition 2003
The use of proven design methods, the mastering of concrete behaviour, the understanding of SFRC technology and the constant monitoring of the production process allows Twintec to guarantee the delivery of a totally homogenous jointless flooring slab with panel sizes of up to 3,000m2 (subject to concrete quality and availability)
Contraction joints will be required at the edge of each pour, given the practical limits on the area of floor that can be constructed at any one time.
Benefits
Jointless floors
High dosages of steel fibres mixed uniformly through the concrete redistributes the shrinking stresses through the drying phase, eliminating the need for saw-cut induced contraction joints – the only joints required are those at the perimeter of each pour.
Reduced maintenance cost
Joints are the biggest cause of floor problems – fewer joints = less maintenance and higher MHE efficiency
Reduced programme time
No steel reinforcement necessary in advance of works
Reduced risk
Reinforcement is always in the right place, and the quality control process is significantly simplified
Improved tolerances
SFRC delivers reduced plastic settlement and therefore improved flatness.
Sustainability
Slab thickness reduced and cement replacement used
Health and safety
Trip hazards are eliminated because traditional reinforcement is not required in the concrete
Price
Cost advantages from increased output, thinner slabs and no requirement for remedial grinding
Dry-shake Topping
All Twintec steel fibre reinforced jointless floors have a Twintop dry-shake topping.
Twintop is a factory blended dry-shake topping incorporating ultra durable aggregates, cement and pigment. Available in a range of grades and colours (standard and metallic), it creates a superior hard-wearing surface with abrasion resistance up to 20 times that of quality powder floated concrete. The result is a long-life, low-maintenance jointless floor for industrial and retail applications that will probably outlast the building.
