Specialized Capabilities
Expansion Joint Systems
- Sealing of movement joints in multi-story structures and bridges
- Use of high-movement elastomeric tape and bandage systems
- Mechanical protection for heavy-duty trafficable joints
- Ensuring continuous waterproofing across large structural gaps
Movement Joint Sealing
- High-performance polyurethane, polysulfide, and silicone sealants
- Accommodation of thermal, seismic, and structural movement cycles
- Excellent adhesion to concrete, aluminum, and glass substrates
- Durable weather-sealing for facades and building envelopes
Joint Injection & Remedial Sealing
- Remedial pressure injection for leaking expansion joints
- Use of flexible polyacrylate gels for permanent water-tightness
- Reinforced joint protection systems for critical infrastructure
- Technical solutions for failing waterbars in deep substructures
Application Method
We follow a rigorous multi-stage application process including substrate preparation, priming, base-coat application, reinforcement layers, and high-performance top-coats. Quality control checks are performed at every milestone to ensure compliance with ASTM and local SASO standards.

Frequently Asked Questions
How long does expansion joint waterproofing take?
Individual joint runs often complete in 1–3 days. Full car-park or podium programmes are phased to limit disruption.
What warranty do you provide on expansion joint treatment?
Written workmanship warranty of 5–10 years depending on system type, substrate condition, and maintenance. Exact term is stated on the project quotation.
Why do expansion joints leak in Saudi buildings?
Thermal movement, UV exposure, traffic loading and failed sealants cause joint degradation. Water then penetrates podiums, basements and parking structures.
How are expansion joints repaired?
Failed sealant is removed, joints are cleaned and primed, and high-performance polyurethane or hybrid sealant systems are installed to design movement capacity.
Can expansion joint repair be done without shutting down a car park?
Phased repair programmes can limit disruption. Pedox engineers assess traffic patterns and propose staged works to maintain partial operation where possible.
