How do you control voids in the wall?
The concrete mix is a high slump 5″- 6.5″ (125 mm – 165 mm) with a smaller aggregate size so the concrete flows easily. The person in charge of placing the concrete should watch the concrete flow throughout the whole wall to ensure there are no void pockets. Internal vibrating provides good consolidation, eliminating voids.
Is the Fox Blocks product rated by ‘Energy Star’?
Energy Star does not evaluate or rate insulation products. Every Fox Blocks home when tested by an Energy Rater, can meet and exceed the Energy Star home standards and achieve a 5 Star rating and a ‘HERS’ score well below the minimum Energy Star requirement of 85, or in Canada, higher than an EnerGuide rating of 80.
ICF Builder Awards Round Up
We thought we’d share a round up of some of our previous awards.
Is there a problem when placing concrete, dropping concrete from the top of the wall which may be over 8' (2.4 m)?
No. Specifications in the America Concrete Institute (ACI) do not limit the maximum distance concrete can free fall. Engineering studies and reports have shown that free fall from up to 35′ doesn’t reduce concrete quality and there is no evidence of segregation or weakened concrete strength. ICF concrete design calls for a high slump mix which assists in reducing segregation.
