why not using ICF GSB walls method

big blocks size which complicate the architecture planing
big blocks size which complicate the architecture planing. The dimensions of ICF GSB big blocks often exceed standard module sizes demanded by architects causing difficulty in coordinating structural elements with interior layouts and limiting design flexibility during planning and execution. This mismatch leads to extended planning phases and potential redesign requests from clients impacting project schedules and budgets
big blocks thickness of extra 7 cm each side for the isolated foam
big blocks thickness of extra 7 cm each side for the isolated foam. Adding seven centimeters of foam insulation to each side of ICF GSB blocks increases wall thickness beyond normal constraints creating challenges in site layout and reducing interior usable space. This extra dimension may require reworking door and window openings and can affect overall square footage calculations leading to cost overruns
often casting failures at concrete works
often casting failures at concrete works. Frequent failures during concrete casting in ICF GSB walls occur when foam panels shift or leak leading to voids honeycombing and weak spots. Such defects compromise structural integrity and require costly repairs including chipping out bad concrete and recasting sections causing delays and budget increases
overal risky works creating unpredicted future results
overal risky works creating unpredicted future results. The ICF GSB method involves complex installation sequences and reliance on foam integrity increasing the risk of unforeseen structural issues over time. If any step is executed incorrectly the resulting defects may only become apparent years later posing safety hazards and requiring extensive remediation
foam blocks disintegration from the casted concrete
foam blocks disintegration from the casted concrete. Exposure to alkalis and moisture during concrete curing can degrade foam material adhesion in ICF GSB blocks leading to partial disintegration of panels. This separation undermines wall strength and thermal performance and may result in loose debris within wall cavities that is difficult to remove
expensive plastering works adhesion problems creating risky cracks
expensive plastering works adhesion problems creating risky cracks. The smooth foam surface of ICF GSB walls often resists traditional plaster bonding leading to delamination and cracks under minimal stress. This requires specialized primers or mesh reinforcement adding material cost and labor time while failing edges may create moisture ingress points
objects hanging inability especialy heavy stuff
objects hanging inability especialy heavy stuff. ICF GSB walls lack solid backing for anchors and fasteners making it difficult to hang cabinets shelving or heavy fixtures. Reliable attachment often demands additional blocking plate installation or metal brackets which adds complexity and cost to finishing works
inevitable isolation injuries at internal infrastructure works
inevitable isolation injuries at internal infrastructure works. Cutting channels for electrical plumbing or HVAC within ICF foam often leads to accidental damage of insulation panels and occasionally to nicks in reinforcing ties. Exposing these flaws late in the schedule forces rework of sealing layers and risk of moisture entry
camouflaged mold growth due to moisture problems in the concrete
camouflaged mold growth due to moisture problems in the concrete. Moisture accumulating behind foam panels in ICF GSB walls can create hidden damp pockets ideal for mold growth that remains undetected until affecting indoor air quality. Signs appear only when spores spread to visible areas making remediation expensive and disruptive
uncontroled termites penetration crawling through the foam
uncontroled termites penetration crawling through the foam. Foam in ICF GSB walls provides a pathway for insects termites and rodents to tunnel through unnoticed. Once infestation begins it is hard to locate and eliminate resulting in potential structural damage and costly pest control treatments
expensive maintanance cost for long time span
expensive maintanance cost for long time span. The layered structure of ICF GSB walls requires periodic inspection of insulation integrity seal joints and external finishes. Over the building life cycle these tasks accumulate significant maintenance expenses especially in climates with wide temperature or humidity swings
expensive blocks cost which mimics the overal labour cost
expensive blocks cost which mimics the overal labour cost. The unit price of ICF GSB blocks is substantially higher than conventional formwork materials and the savings in labor due to speed of assembly often offset by premium material costs. This narrow margin makes budgeting difficult and can nullify expected cost advantages
