Frequently Asked Questions & Verified Engineering Answers

No. Covering over rust accelerates internal oxidation in a concealed state, leading to sudden partial structural failure. Corroded concrete must be fully removed, rebar protected, and structural mortar applied.

CFRP carbon fiber laminates and sheets are required when a member has lost a significant percentage of its design load capacity, or when facility owners seek to increase service loads without adding dead weight.

It depends on the scope of works. In comprehensive structural ceiling or ground column rehabilitation, temporary evacuation is recommended for safety. In facade works or phased interior restorations, work can proceed safely without vacating.

Dry-mix combines water at the nozzle tip and is ideal for intermittent applications, while wet-mix is pre-batched with water for higher output volume, consistent mix ratios, and lower rebound in large-scale projects.

No. The entire process operates through tiny coin-sized holes (12-16mm) through tile grout joints, which are seamlessly color-matched upon completion without any tile removal or floor demolition.

When executed with certified materials, proper thickness, and UV-reflective top protection, modern systems maintain full integrity for 10-15+ years with straightforward periodic inspection.

Yes. Modern electronic and thermal instruments identify the exact defect point through tiles. When repairs commence, only one single tile needs to be opened right at the fault location.

No. Conventional putty merely masks the surface temporarily; the crack will reappear with the slightest seasonal thermal expansion. The fissure must be structurally grouted or stitched from its core.

Light foot traffic is permitted within 24-48 hours. However, full chemical curing requires 5 to 7 days before exposing the floor to heavy forklifts, delivery trucks, or standing water.

No. Gas lines must never be buried without a continuous ventilated protective sleeve and anti-corrosion wrap. Engineering standards strictly favor exposed or duct-accessible runs for easy regular inspection.

Preventive maintenance uncovers minor defects early (such as small roof ponding before it rusts the slab reinforcement), saving up to 60% compared to major emergency structural rehabilitation.
