Extensia™ is a powerful solution to the problem of shrinkage cracks in interior concrete floor slabs.
|
Extensia™
|
 |
Extensia’s™ advanced design and its ability to reduce shrinkage means there is no need to include any steel within the slab structure.* |
 |
Extensia’s™ enhanced flexural strength will enable floor designers to consider thinner section floors. The environmental and economic benefits of this in conjunction with no steel are therefore substantial. |
 |
Extensia™ allows saw cuts to be pushed out to 20 m x 20 m, which realizes major savings for the clients regarding joint maintenance. |
 |
Extensia™ concrete can be placed using conventional laserscreed methods and traditional finishing processes associated to this type of floor construction. |
