FORM WORK SPECIFICATIONS

The FASTA CONCRETE PAVER provides all the benefits of labour saving, high productivity and enhanced floor flatness/levelness qualities. In order to maximize these benefits, care must be taken to ensure a successful application. In adequate substrate and form support can lead to form failure causing unnecessary job delays and expenses while contributing to poor floor flatness and floor levelness ratings. The intent of these specifications is to establish minimum guidelines to help the contractor choose the most economical and effective form work/support system to fit any job site needs.

It is recommended that at least a day prior to the concrete pour, a dry run be accomplished to test the load capacity of the forms and substrate. Proper job planning is essential to be successful application.

The weighs approximately 1000-2000 kgs. Any paver support (forms, rails, rail supports and substrate) must withstand “point load” at a 2:1 safety factor.

SUBGRADE:

Subgrade must be sound enough to support slab edge forms and bracing as well as the load imposed by the paver and its supports. Potential deflection, as in the case with metal and plywood decks, should be considered when determining brace and support spacing. Soil subgrades must be well compacted and must be able to support bearing pressures greater than or equal to those imposed by the paver support and the slab forming. For proper bearing supports, shims should be used to adequately distribute loads where grade is not level and is soft. Use standard AC concrete form pressures when calculating lateral loads on slab edge forms.

SCREED RAILS AND SUPPORT:

Screed rails and supports, independent of slab edge forming are a preferred method. Due to strength, deflection and traction considerations, 3.5” x 3.5” x 875(3/16”) wall structural steel tubing with adjustable supports spaced will be the perfect choice. Standard deflection with 3/16” wall thickness for the above configuration is 1/6” in 4 ft. Refer a standard material charts for other configurations.

STEEL FORMS:

Paving forms with 900 lip-edges at bottom with stake pockets is preferred. If soft or unlevelled subgrade is encountered, a 2xbearing pad and /or shims should be used under the steel forms for additional bearing support. Depending on slab thickness and subgrade, forms may require diagonal bracing.
