Taper Top forms are specif­i­cal­ly designed to pro­vide a larg­er bear­ing sur­face along the top of the wall. Typ­i­cal­ly, the increased bear­ing sur­face may be used to sup­port mason­ry, floor or roof loads. Taper top forms are used in the tran­si­tion from ICF to wood frame con­struc­tion and the taper top form would be the top form on the wall.

Fox Blocks forms have a reversible inter­lock sys­tem on all blocks. The robust inter­lock allows the blocks to fit togeth­er very tight­ly, elim­i­nat­ing any require­ment for adhe­sives. A reversible inter­lock speeds up the instal­la­tion.

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.

The con­crete must cure for a min­i­mum of 7 days and the foun­da­tion wall must be lat­er­al­ly sup­port­ed, mean­ing the floor sys­tem is installed sup­port­ing the top of the wall. All below grade water­proof­ing / damp­proof­ing must be installed.

Yes. The forms insu­late the con­crete and enhance the cur­ing process. The top of the forms, or exposed con­crete areas will need to be cov­ered, tem­porar­i­ly, with insu­la­tion to pre­vent the exposed con­crete from freez­ing. Fox Blocks projects can be con­struct­ed any time of the year, no delays for cold weath­er.

No, the EPS has no struc­tur­al capac­i­ty to sup­port any loads. Wood sill plates must achieve the required bear­ing from the con­crete with­in the ICF. A wood plate that can­tilevers ¹⁄₃ over the EPS and bears ²⁄₃ on the con­crete is allow­able. This can be done with a min­i­mum 2 x 6 plate. If a 2 x 4 plate is required, a taper top form should be used to extend the con­crete under the plate.

To alle­vi­ate the pres­sure from the liq­uid con­crete, the con­crete is placed in lay­ers or ​‘lifts’. The first lift is lim­it­ed to 4′ (1.2 m) of con­crete around the perime­ter of the build­ing. This allows approx­i­mate­ly one hour for the con­crete to set-up before con­tin­u­ing with the next 4′ (1.2 m) lift. The low­er lift pro­vides sup­port for the next lift as the con­crete is placed con­tin­u­ous­ly around the build­ing in con­sec­u­tive lifts to the top of the wall.
