We are trying to decide between building our Manuel Antonio home using traditional concrete block construction, or using IFC construction.
http://www.huduser.org/publications/destech/icf_2ed.html
According to our architect, an American who is licensed in Costa Rica, he tells us that there are a few good construction companies using this new method, with great results, more so in the North of the country so far.
Does anybody have any experience or opinions using this material?
I’ve looked into it and have discovered it’s pro’s and con’s, and will be happy to share them if anyone wants to get a discussion going.
Thanks.
MarkICF building systems sound great and make sense on paper, but here in CR all the input I have received from contractors who have used the various systems over the last 10 years has been negative. Most builders have discovered that it’s more practical and structurally sound to use traditional concrete block and solid concrete columns. Because of the ICF’s energy efficiency there is now new interest as related to “Green Home Building”. However, the proprietary installation and finishing methods are challenging when the majority of the local tradesmen are accustomed to traditional concrete construction. Expect to pay at least 10% more for an ICF home here in CR where the materials are not widely accepted. Additionally, ICF construction requires subcontractors to follow certain proprietary installation methods and the electrical wiring, A/C, plumbing, and drywall installations are different than with traditional construction. This will cause labor prices to be higher because finding subcontractors that have experience working with ICF systems is not easy. Another consideration for building with ICF’s is their resale value. Most buyers, when given the choice, prefer traditional concrete block dwellings. What type of ICF are you considering?
