Structural Problems and Its Solutions

1
Structural Protection

• Various Structural Issues and Its Solutions

2
What Is Structural Protection

• Structural protection involves condition
  assessments and investigating material testing as
  well as costings for structural repair works.
• This involves the application of structural
  strengthening using Carbon fibres. These carbon
  fibres are reinforced polymers with latest
  technologies.
• Structural Protection also involves
  investigations and condition surveys i.e.
  material testing.
• Structural Protection also includes
• Concrete Repairs
• Protective Coatings, Waterproofing and flooring
• Grouting
• Leak Sealing
• And various other applications.

Water Leakage Through Cracks and Joints or
Penetration through the concrete
Here are some structural problems and their
solutions

• Water Leakage Problems through cracks and joints
  is one of the common problem in structural
  buildings.
• Solutions to these problems are
• Injecting Hydrophobic and aqua reactive acrylic
  and polyurethane resins.
• Use of unique sealants. These sealants are
  capable of being applied and bonded underwater

4
External Roof Membranes Allowing Water Ingress
and results in Extensive Damage and Costly Repair
Bills

• Sheet and Liquid Applied Membrane Systems
• These membrane systems are capable of
  withstanding the heaviest of downpours, UV
  degradation and strong winds

5
Internal Roof Membranes and Lining Systems Due to
head pressure, moisture drive or osmatic
blistering

• Sheet and Liquid Applied Membrane Systems
• These membrane systems are capable of
  withstanding the heaviest of downpours, UV
  degradation and strong winds
• Use of Deep Penetrating (90mm) waterproof
  sealers.
• These sealers prevents moisture and vapour drive

6
The Onset of ASR/Aar (Alkali-Silica
Reaction)/(Alkali-Aggregate Reactions)

• Use of deep penetrating waterproof sealers.
• These waterproof sealers greatly reduce water and
  vapour drive
• It also extracts fluid contaminants our of the
  concrete.

7
Spalling Concrete caused due to Freeze Thaw
Cycling

• Proper Use of Surface and penetration sealers
• These penetrating sealers are used for prevention
  and concrete repairs for remediation

8
Landslip Due to heavy Saturated Soil

• Ground Stabilisation
• Utilisation of range of Techniques and Materials
  
• These Materials include hydrophobic polyurethane
  ground and rock anchors.

9
Stain on Structures Due to Increased Loads and
structural deficiency

• Application of Fibre Reinforced polymers in
  sheet, rod or plate form.
• These provides significant benefit over
  strengthening using steel.

10
Concrete Failure Due to Corrosion of
Reinforcement Bar

• Reapplication of Protective Coating to Rebar
• Application of concrete breakout around
  reinforcing bar.
• Mechanical Removal of Dust.
• Reinstatement of Concrete using resin based
  Mortar.

11
Carbonation Caused From reaction of Calcium
Carbonate in Concrete

• Application of Specialised Anti-Carbonation
  Coatings.
• These Coatings fill surface pores and bridge fine
  cracks.
• It also form a barrier to the movement and
  ingress of Carbon Dioxide.

12
Hydrogen Sulfide (H2S) Attack
13
Hydrogen Sulfide (H2S) Attack Above Water line in
Sewerage System Structures

• Application of Epoxy and polymer modified
  cementitious coatings on damp surfaces.
• Application of Epoxy coatings on Dry Substrates.
• These coatings are highly chemically resistant to
  sulphide and other forms of chemical attack.
