How does the ICF block get secured to the foundation?
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 4th 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.

The chal­lenge for this build was to cre­ate a home that would appeal to a sophis­ti­cat­ed buy­er with fea­tures that an emp­ty nester mov­ing from a larg­er more expan­sive home would enjoy. The result is an ener­gy effi­cient home which cre­ative­ly uses space in an attrac­tive, lux­u­ri­ous, and cost effec­tive way.

5 Common Misconceptions About ICF Construction
ICF con­struc­tion cre­ates mod­ern struc­tures that are ener­gy-effi­cient, durable, dis­as­ter-resis­tant, and have good indoor envi­ron­men­tal qual­i­ty (IEQ). ICF con­struc­tion is also strong, flex­i­ble, fast and easy to install. Unfor­tu­nate­ly, even with these many ben­e­fits, some archi­tects and con­trac­tors are reluc­tant to uti­lize it due to mis­con­cep­tions about ICF con­struc­tion.
Can I leave Fox Blocks forms exposed to ultraviolet rays for an extended period (months)?
Yes, but you will notice a light dust­ing on the sur­face and a yel­low­ing dis­col­oration of the forms. This does not indi­cate any detri­men­tal effects to the ICFs. We do sug­gest, that if the exte­ri­or fin­ish is not going to be installed with­in around a 3 month peri­od or more, the forms be pro­tect­ed from UV rays by installing a tem­po­rary build­ing wrap type mate­r­i­al. The pow­dery film must be removed with soap and water before the appli­ca­tion of a syn­thet­ic stuc­co fin­ish or water­proof­ing mem­brane.

What fasteners are recommended for ICFs?

Fox Blocks has con­duct­ed numer­ous fas­ten­er tests for pull-out strength and shear capac­i­ty for var­i­ous fas­ten­ers – screws, ring shank nails and sta­ples into the plas­tic webs. The rec­om­men­da­tion for inte­ri­or and exte­ri­or appli­ca­tions of fin­ish mate­ri­als is for the use of screws which pro­vide the best hold­ing capac­i­ty into the plas­tic webs or fas­ten­ing strips in the forms which are iden­ti­fied on each block.

The EPS insu­la­tion does not pro­vide any hold­ing capac­i­ty for fas­ten­ers.
