Professional Substructure Protection & Leak Injection Services
Thermal drift in Egypt’s aggressive climate creates massive movement in structural slabs. EG-CORE deploys TPE Bandages—not just sealants. These systems are structurally fused to the concrete using moisture-tolerant epoxy resins, creating a permanent, high-movement bridge that handles seismic drift without delamination.
Accommodates 400% elongation. Engineered for roof joints, parking decks, and industrial bridge slabs.
High-modulus bonding exceeds concrete tensile strength (3.5 MPa+), ensuring zero-wicking at the edges.
Every tie-rod hole is a structural penetration prone to hydraulic failure. Our Zero-Leak Protocol eliminates seepage via a 3-layer mechanical barrier: 5cm radius excavation, high-expansion hydrophilic core plugs, and a final crystalline grout fusion to stop water under 5-bar pressure.
Expanding rubber plugs sitting deep in the core swell 300% on moisture contact to kill the leak path.
Non-shrink grout grows insoluble crystals inside concrete pores, making the plug monolithic with the wall.
Coving is mandatory for all structural junctions—rafts, tanks, and retaining walls. Sharp 90° corners concentrate stress and cause membrane failure. We install 50mm radius Polymer-Modified Mortar Fillets to ensure uniform Dry Film Thickness (DFT) and eliminate stress-concentration wicking.
Distributes hydrostatic and mechanical loads across the junction to prevent waterproofing tears.
Applied using high-modulus, zero-shrink structural repair mortars for absolute durability.
Bandages are required for joints exceeding 30mm or in facilities prone to thermal drift where liquid sealants would snap under tension.
5cm ensures the removal of the plastic formwork cone and provides enough depth for the hydrophilic plug to sit in the center of the wall core.
Crystalline chemicals react with moisture to grow insoluble crystals that block the capillaries and pores of the concrete itself.
Yes. Any 90° internal junction is a weak point; coving is a structural standard to prevent membrane failure under hydrostatic load.
In Egypt, high sulfate and chloride levels in groundwater can corrode rebar if detailing is poor. Our TPE bandages and epoxies are 100% chemically resistant to saline environments.
Our structural epoxies are moisture-tolerant, allowing for high-strength bonding even on damp concrete shoulders, which is critical for projects in high-humidity coastal areas.
