Surface repair replaces defective, damaged or deteriorated concrete, restores structural function, protects itself or underlying concrete from aggressive environments and restores any lost performance requirements.
Once the outward signs of structural problem have been observed, the next step is crucial: to identify the underlying cause. Any decision to repair and repair strategy should never be based solely on effect; it should always arise from the analysis of the cause. A solid understanding of the root cause will help determine whether the observable defects actually warrant a repair.
We at Structural Specialties, specialize in managing projects of both Large and small repair schemes and our teams are experienced in external repair works including concrete repairs, plasters and renders, Water-proofing and protective coatings, replacing and stabilising existing brick work and roofing repairs. We are able to manage complicated access arrangements and can offer alternate and innovative access solutions to maximize productivity and enhance safety.
We have experience of working in occupied premises such as office blocks, residential premises, factories, hotels, hospitals malls school establishments.

The need for strengthening may arise from deterioration, change in use, change in design code, structural defects and seismic conditions. Structural Specialties utilizes the latest technologies to develop innovative strategies to restore or add load carrying capacities to bridges, buildings, silos, industrial plants, Water retaining structures.
Stabilization is the process of halting an unwanted situation from progressing, such as cement grouting the soil around a settling structure to stop further movement.
Since strengthening and stabilization methods are closely related, they are often used in combination.
Many techniques are available to strengthen and stabilize structures. These techniques include the addition of Steel, FRP composite systems, Micro concrete or other specialized materials to existing members, or by modification of foundation soils.
Structural Specialties provides economical strengthening solutions for structures requiring load capacity upgrades, drawing form many years of experience.

Moisture problems are critical issues that must be addressed quickly in order to maintain functionality, create long term durability and avoid other related deterioration. At Valka Care and Services our solution has extensive experience in identifying sources of water intrusion and developing a range of alternatives for service life requirements. Our expertise includes identifying the root cause and source of water problems, select the right materials and development of a constructible design solution that can be implemented properly.
Engineered Moisture Control & Waterproofing Solutions
Stoppage of Leakages is as much as an art as it is a science. Water-proofing and protection techniques are used to control deterioration of structures. Underground, liquid retaining structures, roofs constructed from Concrete, brickwork or block work can often leak immediately after construction or during its service life. Water-proofing techniques prevent water from entering or exiting a structure through cracks, joints or
failed water-stops, while protection techniques extend the length of time between maintenance cycles. Our Structural Specialties is able to provide a complete service from identification of the root cause of failure to providing a comprehensive repair solution for stopping all leakages.
