Frequently Asked Questions
How much does crack injection cost in Saudi Arabia?
Indicative pricing is from 150–400 SAR per linear metre. Final cost depends on crack length, access, and whether leaks are active. A free site survey is required for an accurate quote.
How long does crack injection take?
same-day to 2 days for most active leak repairs. Larger basements or multi-zone tanks may need a phased programme confirmed after inspection.
What warranty do you provide on crack injection?
Written workmanship warranty of 5–10 years depending on system type, substrate condition, and maintenance. Exact term is stated on the project quotation.
What is crack injection waterproofing?
Crack injection uses high-pressure PU or epoxy resins injected into concrete cracks to seal water ingress and restore structural integrity without full demolition.
When should I use PU vs epoxy crack injection?
PU injection suits active or moving leaks with water ingress. Epoxy injection is preferred for dry, structural cracks where load-bearing capacity must be restored.
Can crack injection stop active leaks in basements?
Yes. Hydrophilic PU systems can arrest live water pressure in basement walls, tanks and retaining structures common in Saudi substructures.
Which Saudi cities does Pedox serve for crack injection?
Pedox provides crack injection services across Riyadh, Jeddah, Dammam and Al Khobar, with rapid mobilisation for urgent leak repairs.
