View Technical SpecsLima, the capital of Peru, is undergoing rapid vertical real estate growth, massive logistical expansion (including the mega-port of Chancay and Jorge Chávez Airport expansions), and heavy municipal transit revitalization. However, its geographic placement presents severe material science challenges.
With relative humidity frequently hovering between 85% and 95% ("La Garúa" mist) and intense oceanic chloride concentrations from the Pacific coastline, plain concrete structures in Lima suffer accelerated carbonation and reinforcement steel corrosion. Traditional structural cement patches fail within 12 to 24 months due to delamination caused by high osmotic pressures and thermal variations.
As a leading high-tech manufacturer, we provide tailored, polymer-modified cementitious concrete resurfacing products engineered to withstand these precise coastal and geotechnical parameters, guaranteeing longevity and structural safety.
Structural strengthening and concrete rehabilitation engineering applied to high-rise developments in San Isidro.
Bridging international chemistry standards with South American geotechnical realities to design lifetime concrete systems.
Lima lies in Zone 4 (highest seismic category) of the Peruvian Seismic Standard NTE E.030. Our resurfacing matrices incorporate hyper-flexible elastomeric polymers that deform elastically during seismic events, preventing cracks from propagating through to structural elements.
By balancing silica fume micro-fillers with specialized acrylic polymers, our overlays resist driving sea mists (humid chloride intrusion) while allowing internal concrete vapor to escape harmlessly, eliminating blistering and delamination.
Minimizing lane closures on arterial systems like Vía Expresa Paseo de la República is crucial. Our fast-drying resurfacers achieve structural load capacity (compressive strength > 30 MPa) within 2 to 4 hours post-application.
Ultra-High Performance Concrete (UHPC) cladding systems implemented on external facades facing coastal elements.
Modern architecture in districts like Miraflores demands structural materials that act as protective skins. Ultra-High Performance Concrete (UHPC) panels represent a paradigm shift. Possessing a dense internal matrix with virtually zero capillary porosity, UHPC completely isolates buildings from ocean salts and humidity.
Sino-Sina / Shengchuang has pioneered the engineering of UHPC panel formulations since 2008. By incorporating steel and organic micro-fibers, our precast UHPC panels achieve flexural strengths that traditional concrete cannot match, enabling highly complex architectural shapes while guaranteeing durability exceeding 100 years.
Explore UHPC Product CatalogHow we ensure every batch shipped to Lima ports exceeds ASTM and Peruvian NTE standards.
Silica sand, high-density aluminate cement, and proprietary dry polymers undergo rigorous X-ray diffraction (XRD) and particle size distribution (PSD) tests to guarantee aggregate consistency.
Introduction of redispersible polymer powders (RPP) optimized for high relative humidity environments. This step controls drying shrinkage, which is the primary cause of cracking in standard patches under coastal climates.
Every production batch is cast into standard prisms and tested under ASTM C109 and ASTM C1583. Direct pull-off tests on concrete substrates must register values > 2.0 MPa (substrate failure) before international shipping approval.
Products are sealed in multi-layer water-resistant PE-lined valve bags and shrink-wrapped onto structural pallets to protect them against high humidity during their sea voyage to Callao Terminal.
Empowering local municipal and industrial sectors with localized concrete solutions.
Restoration of multi-level underground parking slabs showing signs of micro-cracking and carbonation. Application of our self-leveling, micro-silica modified underlayments restored load ratings and protected high-value real estate assets.
Logistics warehouses experiencing heavy forklift impact and aggregate wear. Resurfaced with our high-impact resistant, dustproof patching compounds, restoring wear resistance and extending floor cycle-life by over 10 years.
Dock loading platforms constantly exposed to salt water splash zones and severe axle loading. Utilizing high-performance fast-drying cement repair concrete compounds allowed fast traffic return, minimizing operational downtime.

High relative humidity slows water evaporation from the fresh mix, which is beneficial for hydration but can delay early strength if the formula is not balanced. Our formulations contain specialty early-hydration catalysts that consume excess moisture quickly, forming dense calcium-silicate-hydrate (C-S-H) gels. The low-porosity matrix prevents atmospheric chloride ions from penetrating the concrete, protecting structural rebar from galvanic corrosion.
Yes. Standard cementitious mortars are brittle and crack under minimal shear forces. Our specialized concrete resurfacers incorporate a high dose of cross-linking redispersible polymers (RPP) that create a secondary co-matrix inside the cured concrete. This flexible network provides tensile elongation capabilities, allowing the material to bridge fine micro-cracks under seismic movement without delaminating.
Our materials are manufactured under ISO 9001 and ISO 14001 guidelines and fully comply with ASTM C928 (Standard Specification for Packaged, Dry, Rapid-Hardening Cementitious Materials for Concrete Repairs) and EN 1504 structural rehabilitation requirements. Testing data matches building code requirements set forth in Peruvian standards NTE E.060 (Reinforced Concrete).
Our polymer-modified thin-coat concrete resurfacing line can be applied from feather-edge (approx 1.5mm) up to 15mm in a single pass. For structural repairs and deeper patch work (up to 50mm), we supply aggregate-extended formulations that control thermal stress and volume shrinkage.
