The ultimate low shrinkage flooring solution READYMIX CONCRETE
Traditionally, the only way to reduce shrinkage and cracking in industrial, warehousing and commercial concrete internal floors has been through mesh or steel fibre reinforcement. While durable, this option is time-consuming, costly and environmentally unsustainable. Now there is an alternative from Lafarge Tarmac. A sustainable flooring solution that offers very real benefits to floor designers, contractors and end-users. Solving the problem of shrinkage cracks, eliminating the need for steel mesh, and saving time and money. SOLUTION Extensia from Lafarge Tarmac. The ultimate low shrinkage flooring solution. Extensia provides superior flexural and compressive strength fast. Its unique crack control technology reduces shrinkage without the need for steel mesh reinforcement, delivering a more efficient floor design.
BENEFITS Sustainable Compared to traditional steel mesh or steel fibre reinforced concrete, Extensia can reduce CO 2 emissions by up to 20%. HOW IT WORKS Extensia is a low shrinkage concrete for use in ground bearing slabs. Extremely durable, with very high abrasion and impact resistance, it provides superior flexural and compressive strength, without the need for steel or mesh reinforcement. Reduced thickness Its enhanced flexural strength enables the installation of a more efficient flooring section. Less joints Saw joints can be spaced out to 20m x 20m without the requirement for steel. Cost-effective Less material usage, high surface durability and lower maintenance costs can significantly reduce whole life costs. Ease Extensia can be placed using conventional laserscreed methods and traditional finishing processes. Faster working Time is saved through early power-trowelling and joint cutting, while high compressive strength means slab loading can begin at just 14 days. Durable Extensia is highly durable without surface treatment, achieving BS-8204 standard. Reduces shrinkage, time and costs The mechanical and shrinkage properties of Extensia enable the design of thinner and unreinforced slabs, with increased joint spacing at 20mx20m (400m²). Construction can be shortened through early power-trowelling and joint cutting, while slabs can be loaded from just 14 days. The drastic reduction of joints, limited curling and high surface durability combine to deliver substantial savings in maintenance and whole life costs. High strength durability Combine low oxygen permeability and low water porosity with high compressive and flexural strength, and you have a flooring solution that is designed to last. ULTIMATE DURABILITY Extensia provides superior flexural and compressive strength without the need for steel reinforcement.
Subjected to all types of wear from heavy machinery, abrasive oils and high point loads, Extensia is a proven solution for internal industrial and commercial floors. INSPIRED SOLUTIONS FOR INTERNAL FLOORS Typical applications Extensia is breakthrough technology, meeting the market s need, based on the understanding of hydration, shrinkage and the cracking associated with a concrete floor s structural behaviour. The unique patented Extensia solution uses crack control concrete technology offering a tangible advantage for floor designers, contractors and end users.

EXPERIENCE This is a far superior finish with no cracks and a strong smooth finish. Pauline Dawes, Managing Director, Somi Trucks Not only have we achieved a floor that looks good and meets our requirements in every respect, with a saving in cost, but it is also environmentally sustainable. Dean Marlow, Site Manager, Raymond Brown Construction Loxley Building, Scunthorpe CHALLENGE The Loxley Building was commissioned by Somi Trailers who manufacture and repair innovative lorry trailers. This huge 1,750m² floor area was to be subjected to heavy loads and surface abrasion meaning the original specification was to use a 200mm thick slab with 30kg of steel fibres. An alternative was sought. SOLUTION Extensia was chosen eliminating the need for steel reinforcement and allowing for a reduction in slab depth, while still meeting the load requirements of the floor. A total of 284m³ of Extensia was laid over an 8 hour period. RESULT The entire floor was laid quickly and cost effectively giving the client substantial cost savings, a thinner floor slab and a more sustainable solution. New waste transfer station, Fareham CHALLENGE Due to the type and size of the heavy plant that would be in operation, the floor slab had to be extremely durable with very high abrasion and impact resistance, and as few joints as possible. SOLUTION Extensia was the only flooring solution that answered every challenge. The entire floor area of 1,850m 2 at a depth of 200mm was completed over just a two day period. The saw cut detail was extended to 20x20m, dramatically reducing long-term floor maintenance and removing the issue of steel fibre pop outs which can occur under heavy traffic. RESULT A long-lasting, durable finish was achieved with no surface cracking so often associated with industrial floor slabs. ULTIMATE RESULTS Extensia is proven concrete technology, saving time and money.
