Allied Concrete READY Floor is a concrete flooring system that contains integral reinforcement in the form of steel fibres.

Allied Concrete READY Floor is intended to use:

• for residential floor slabs with combined foundations for houses within the scope of NZS 3604:2011; or,
• for separately poured floor slabs with conventionally reinforced foundations for building within the scope of NZS3604:2011; or,
• for commercial and/or industrial concrete slabs-on-ground from 100 mm to 150 mm thick.

1. Allied Concrete READY Floors have been certified for use in slabs within the following scope limitations:

• a. for residential floor slabs with combined foundations for houses within the scope of either NZS 3604:2011 or NASH, built on good ground as defined by the B1/AS1 and B1/VM1, 
• b. for separately poured floor slabs with conventionally reinforced foundations for building within the scope of either NZS 3604:2011 or NASH, built on good ground as defined by the B1/AS1 and B1/VM1
• c. as commercial and/or industrial concrete slabs-on-ground from 100 mm to 150 mm thick, on soil with a modulus of subgrade reaction of k>30 kPa/mm.

2. Allied Concrete READY Floor is not suitable for soils that are expansive or prone to liquefaction or differential settlement. The soil that the slab is to be poured on must be “good ground” as defined by the B1/AS1 and B1/VM1. For specific engineering design the modulus of subgrade reaction, k, must be greater than 30 kPa/mm.

3. When Allied Concrete READY Floor is used for constructing concrete slab-on-ground floors for buildings within the scope of either NZS 3604:2011 or NASH with the foundation integral with the floor slab,

• a. slab and foundation must be placed as one continuous pour.
• b. The dimensions of the floor and foundations must be as described in NZS 3604:2011, Figure 7.13 (B) or 7.15 (B), for the concrete slab-on-ground with combined foundations. There is no requirement for the steel mesh or R10 stirrups and only one D12 bar is required at each of the top and bottom of the footing. These bars must be installed in accordance with the Allied Concrete READY Floor Brochure 11/16/V1. The minimum depth of Allied Concrete READY Floor foundations below cleared ground level shall be 200 mm as specified by NZS 3604:2011, Paragraph 3.4.2. The inner face of the foundation shall slope up to the underside of the integral floor slab at an angle of approximately 45º, as shown in NZS 3604:2011, Figure 7.13 (B).
• c. satisfactory cover to any supplementary steel incorporated in the concrete must be maintained.
• d. the dimensions of slab thickenings under internal loadbearing walls must be as described in NZS 3604:2011, Section 7.5.11, except that there is no need for additional reinforcing.

4. When Allied Concrete READY Floor is used for constructing concrete slab-on-ground floors for buildings within the scope of either NZS 3604:2011 or NASH with foundation poured separately,

• a. they must be in accordance with NZS3604:2011, Figure 7.13 (B), 7.14 (B) or 7.15 (B), including the reinforcement steel and its coverage; and,
• b. The slab may then be poured at a later date, and mesh not required.
• c. the dimensions of slab thickenings under internal loadbearing walls must be as described in NZS 3604:2011, Section 7.5.11, except that there is no need for additional reinforcing.

5. For other concrete slab within the scope of this certification including building subject to Specific Engineering Design,

• a. Table 1 gives the maximum loads for different slab thicknesses for Allied Concrete READY Floor.
• b. Thickness up to 200mm may be used provided the allowable loads do not exceed what is shown in Table 1, or specific design is required.
• c. Allied Concrete READY Floor commercial / industrial ground floor slabs should be detailed following industry best practice, such as but not limited to:
  • i. isolating slabs from beams or internal columns; 
  • ii. local reinforcing at re-entrant corners; and
  • iii. incorporating free movement joints with dowels, where necessary, to transfer slab loads across joints.
