• Advantages
  • High level of abrasion resistance

  • 60 MPa - Integral strength surpassing that of surface hardeners

  • Increased joint durability

  • Highly fluid during placement, reducing construction time

  • Early loading due to early strength development

  • Low permeability (< 1500 coulombs)

  • Up to 30% less joints

  • Finishing
    • Finishing can typically begin 4 hours af terbatching.
    • Finished slab should be wet cured under plastic for a minimum of 7 days.
    • Slabs constructed should be saw cut as soon as possible and to a depth of at least one third of slab thickness

Extensia : Premium Flooring solutions using the latest concrete innovations


Extensia™ combines state-of-the-art concrete technologies to achieve high strengths and low shrinkage while simplifying the construction process.


Extensia™ technology can provide you with a superior commercial concrete floor


The compressive and flexural strength properties of Extensia allow for maximum flexibility in design. Engineers can use Extensia as an alternate to standard 25 MPa Portland cement concrete, enjoying greater freedom in slab thickness and joint layout. Extensia™ can be used in a wider variety of environments thanks to its advanced properties.

Tangible Benefits

Increased strengths lead to higher load capacity and true heavy duty useage, leading to lower lifetime costs. Additionally, the early strength development of Extensia™ results in construction loading strengths in as little as 7 days – leading to faster HVAC, lighting and electrical installations. Tangible Benefits


Traditional high strength concretes are developed with mixes using higher amounts of cement – thereby increasing the CO² content associated with the floor production. Extensia™ uses a combination of advanced concrete design technologies to achieve higher strengths without signinicantly increasing the CO² content of the flooring system.

Authorized Contractors

Only Lafarge Authorized Contractors can place Extensia™ floors. Authorized contractors are highly qualiifed have been selected by Lafarge for their experience and technical ability. Please contact your Lafarge representative for a list of Authorized Contractors in your area.

Site Requirements

Extensia™ is highly fluid in application, and can allow maximum productivity from placing crews. Slabs can generally be placed, finished and cut within 18 hours. Slabs must always be wet cured under plastic for seven days.
