INSPECTION + ENGINEERING + EXECUTION + PROTECTION

Structonix is a specialized engineering division of Skylark Constructions Pvt. Ltd., established in 1990, dedicated to structural retrofitting, structural repair and rehabilitation, concrete restoration, and advanced waterproofing solutions. With a strong execution-focused approach, we work to extend building life, enhance structural safety, and prevent long-term deterioration or failure. Serving Greater Mumbai, Thane, Navi Mumbai, Kalyan-Dombivli, Mira-Bhayandar, Vasai-Virar, Panvel, Ulhasnagar, and Bhiwandi, we deliver technically engineered, durable, and performance-driven solutions for residential societies, commercial buildings, and industrial structures across the Mumbai Metropolitan Region.

our core services

If your building shows cracks, deflection, corrosion, or structural distress — immediate strengthening is critical.

We provide:

  • RCC Jacketing (Columns, Beams, Slabs)
  • Carbon Fiber Wrapping (FRP Strengthening)
  • Steel Plate Bonding
  • Load Enhancement Solutions
  • Seismic Retrofitting
  • Foundation Strengthening

We don’t just recommend — we design and execute.

Over time, Mumbai’s coastal environment causes:

  • Reinforcement corrosion
  • Concrete spalling
  • Structural cracks
  • Carbonation damage

Our repair systems include:

  • Polymer Modified Mortar Repairs
  • Micro Concrete Jacketing
  • Injection Grouting
  • Corrosion Protection Systems
  • Structural Crack Repair

We restore structural integrity — not just surface appearance.

Water ingress is the #1 cause of structural deterioration.

We use modern systems such as:

  • Crystalline Waterproofing in Concrete
  • PU Liquid Membrane Systems
  • Terrace & Podium Waterproofing
  • Basement Leakage Treatment
  • Injection Grouting for Active Seepage
  • Expansion Joint Sealing

No outdated brick-bat coba.
We use performance-based waterproofing technology.

Frequently Asked Questions

What is structural retrofitting?

Structural retrofitting is the process of strengthening an existing building to improve its load capacity, structural safety, and long-term durability. It may involve column jacketing, beam strengthening, carbon fiber wrapping, steel reinforcement, or foundation enhancement.

A building requires structural repair if you notice structural cracks, exposed reinforcement steel, concrete spalling, corrosion damage, water seepage, slab deflection, or reduced load capacity. Early intervention prevents major structural failure.

Hairline plaster cracks are usually non-structural. However, diagonal cracks in beams/columns, widening cracks, or cracks accompanied by rust stains or water leakage may indicate structural distress. A technical site inspection is required to confirm.

Yes, we conduct technical inspection and structural condition assessment as part of our repair and retrofitting projects. Our focus is on actionable engineering solutions and execution. 

RCC jacketing is a strengthening method where additional reinforced concrete is added around existing columns or beams to increase load capacity and structural stability. It is commonly used in old buildings and load enhancement projects.

FRP (Fiber Reinforced Polymer) wrapping is a modern strengthening technique used to increase the load-bearing capacity of beams, slabs, and columns without increasing structural weight significantly.

Yes. Water ingress is one of the primary causes of reinforcement corrosion and concrete deterioration. Proper waterproofing prevents further damage after structural strengthening.

Project duration depends on building size, damage extent, and repair methodology. Small repair works may take a few weeks, while full building rehabilitation may take several months.

Yes. We regularly execute structural repair, retrofitting, and waterproofing works for housing societies (CHS), commercial buildings, industrial structures, and developers across Mumbai Metropolitan Region.

The cost depends on the condition of the structure, repair methodology, material system used (RCC jacketing, micro concrete, FRP, etc.), and project scope. We provide detailed BOQ-based quotations after site inspection.
