How to Choose the Right ICF Builder in Ireland: 5 Questions You Must Ask
Why General Contractors Aren't Enough for ICF
ICF is simple in theory: stack polystyrene blocks, insert steel rebar, and pour concrete. However, concrete exerts massive hydrostatic pressure. If the blocks aren't aligned, braced, and poured at the correct rate, you risk a disastrous structural failure. This is why vetting your ICF contractor is the most important step of your self-build journey.
Key Questions to Ask ICF Builders in Ireland
1. Are you certified by the system manufacturer?
Whether using Amvic, Thermohouse, or Altherm, your builder should have completed official system training. Ask to see their manufacturer certificate.
2. How many multi-storey pours have you completed?
A single-storey garden room is easy. Pouring a double-storey house with pre-cast concrete floor slabs requires advanced engineering. Ask for references for at least 3 completed residential homes.
3. What concrete mix and slump do you specify?
Experienced ICF builders work closely with local concrete plants to ensure the concrete flow is optimal. Too dry, and you get voids; too wet, and you blow out the forms.
4. Do you have concrete-specific public liability insurance?
Ensure their insurance policy covers concrete pumping and formwork erection.
