The ICF blocks are held in place with either low expan­sion spray foam or a met­al starter track. The bracing/​alignment sys­tem, typ­i­cal­ly installed after the 4^th course of block, also sup­ports the ICFs in place. Once the con­crete is in the wall there is no con­cern with the forms mov­ing. The con­crete is con­nect­ed to the foot­ing with rein­forc­ing dow­els.

Acrylic stuc­co is a thin coat fin­ish which can be direct­ly applied to the EPS insu­la­tion on the exte­ri­or face of the ICF. Fox Blocks pro­vides a con­tin­u­ous EPS sur­face con­ducive for the appli­ca­tion of acrylic stuc­co. All acrylic stuc­co man­u­fac­tures are famil­iar with ICFs as a sub­strate and each have their rec­om­men­da­tions for appli­ca­tion over ICFs. Note there is a dif­fer­ence in the instal­la­tion pro­ce­dures between acrylic stuc­co and tra­di­tion­al stuc­co.

ICF homes in Cana­da help builders main­tain their prof­its because of ICFs sta­ble pric­ing and quick con­struc­tion com­pared to above and below grade con­ven­tion­al con­struc­tion.

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.

The evolv­ing and improv­ing field of build­ing inspec­tion, along with real estate reg­u­la­tions, enures that today’s buy­ers can make more accu­rate and informed deci­sions on their build­ing pur­chas­es than they could 50 years ago.
