Project Process FAQs
Everything you need to know about what to expect during a CFRP strengthening project — from initial assessment through installation, quality assurance, and project completion.
What happens during a structural assessment?
A structural assessment includes visual inspection of all structural elements, documentation of cracks, spalling, and deterioration, non-destructive testing (Schmidt hammer, ultrasonic pulse velocity, cover meter surveys), core sampling for concrete strength verification, structural analysis comparing existing capacity to required capacity, and a comprehensive report with strengthening recommendations and cost estimates.
How long does a typical CFRP project take from start to finish?
A typical CFRP project timeline includes 1-2 weeks for structural assessment and engineering design, 1-2 weeks for material procurement and project planning, and 1-3 weeks for installation (depending on scope). Total timeline from initial contact to project completion is typically 4-8 weeks for standard projects. Emergency projects can be expedited with 48-72 hour deployment.
Can my building stay open during CFRP installation?
Yes. CFRP installation produces minimal noise, dust, and vibration. Work is performed in small zones that are rotated through the building, minimizing the area affected at any given time. Most commercial buildings, parking garages, and institutional facilities remain fully operational during CFRP installation. Specific work-hour restrictions can be accommodated for sensitive environments.
Do you handle engineering design and permitting?
Yes. CFRP Repair provides complete engineering services including structural assessment, CFRP strengthening design per ACI 440.2R, stamped engineering drawings, and permitting support. Our licensed professional engineers design every project and coordinate with local building departments as needed for permit approvals.
What quality assurance testing is performed?
Quality assurance includes pull-off testing per ASTM D7522 at a minimum frequency of 1 test per 200 square feet (minimum 200 psi bond strength required), visual inspection for voids, wrinkles, and fiber alignment, coin-tap testing for delamination detection, documentation of all installation parameters (temperature, humidity, material lot numbers), and a final inspection report with test results and as-built documentation.
What surface preparation is required?
Surface preparation includes removal of all coatings, laitance, and contamination; concrete surface profiling to CSP 3-4 (typically by grinding or sandblasting); crack injection for cracks wider than 0.010 inches; concrete repair of spalled or deteriorated areas; and primer application to seal pores and improve adhesion. Surface preparation typically accounts for 40-50% of the total installation time.
How do you ensure proper bonding?
Proper bonding is ensured through rigorous surface preparation (achieving minimum 200 psi concrete surface tensile strength), use of manufacturer-specified epoxy systems applied within temperature and humidity limits, trained installation crews following documented procedures, consolidation with rollers to remove air voids, and pull-off testing to verify bond strength meets or exceeds design requirements.
What happens if a deficiency is found during installation?
If unexpected conditions are discovered during installation (additional deterioration, lower concrete strength, hidden utilities), our engineering team evaluates the finding and modifies the design as needed. We communicate all changes to the building owner with cost and schedule implications before proceeding. This adaptive approach ensures the final installation addresses all structural deficiencies.
Do you provide warranties?
CFRP Repair provides workmanship warranties on all installations. The CFRP material manufacturers provide separate material warranties. Specific warranty terms are included in each project proposal. The 50+ year design life of properly installed CFRP systems provides long-term assurance of structural performance.
What documentation do I receive after project completion?
Project documentation includes as-built drawings showing all CFRP locations and configurations, quality assurance test results (pull-off tests, visual inspection reports), material certifications and lot numbers, installation photographs, engineering calculations and design report, and a maintenance and inspection guide for the installed CFRP system.
Do you serve my area?
CFRP Repair serves all 50 states and Washington, D.C. Our mobile crews deploy nationwide, delivering consistent quality regardless of project location. We maintain regional material sourcing relationships for efficient procurement. For emergency structural repairs, we can typically deploy within 48-72 hours.
How do I get started?
The first step is to request a free structural assessment. You can submit a request through our website, call us directly, or email project details. Our team will review your information, schedule an assessment if appropriate, and provide a detailed proposal including engineering approach, cost estimate, and project timeline.
What weather conditions are required for CFRP installation?
CFRP installation requires ambient temperatures between 50°F and 95°F (10°C to 35°C) and relative humidity below 85%. The concrete surface must be dry and free of moisture. Installations are typically not performed during rain or when rain is expected within the epoxy cure window (typically 24-48 hours). Indoor installations are less affected by weather conditions.
How many crew members are typically on-site?
A typical CFRP installation crew consists of 3-6 trained technicians, depending on the project scope. Larger projects may have multiple crews working simultaneously in different areas. Each crew includes a certified lead installer responsible for quality control and adherence to the installation specifications.
Can CFRP be installed in occupied spaces like hospitals or schools?
Yes. CFRP installation is well-suited for occupied sensitive environments. The process produces minimal noise (no jackhammering or welding), minimal dust (surface preparation can use vacuum-equipped grinders), and no fumes (modern epoxy systems have low VOC content). Work can be scheduled during off-hours and in small zones to minimize disruption to patients, students, or occupants.
