Concrete Repair

Concrete repair is at the core of our business, as with many materials, concrete can degrade over time due to a number of factors – environmental, insufficient maintenance, impact damage, overloading, shrinkage or chemical attack. The propagation of salts and contaminants into a concrete structure often leads to corrosion of the steel reinforcing. The expansive forces of the corroding steel reinforcement can result in cracking and subsequent delamination of the concrete surface

Our in-house team provides a full turnkey service for concrete repair; from survey and inspection and concrete breakout, to the replacement of corroded reinforcement, reinstatement of concrete and application of corrosion inhibitors.

Concrete repair services offered by Cappa Construction & Maintenance include:

  • Survey and inspection
  • Manual concrete breakout
  • Replacement of corroded reinforcement
  • Preparation of steel using abrasive blasting or grinding
  • Reinstatement by dry spray concrete
  • Reinstatement by hand placement
  • Reinstatement using flowable repair materials and formwork
  • Application of coatings and corrosion inhibitors

Structural Strengthening

Structural strengthening is the process of upgrading structures to improve performance under existing loads or to increase the strength of structural members to carry additional loads, Cappa Construction & Maintenance are experience in the installation of structural strengthening systems, these include

Carbon Fibre

Carbon fibre wrapping is used to increase load bearing capacity of concrete beams, columns, slabs and walls, repairing or preventing seismic damage, replace damaged or missing reinforcing steel, it can be used also on new constructions to increase structural load and also provide long – term protection. Quick to install and with minimal impact the successful installation requires experienced and skilled operatives, Cappa Have carried out Installs to CBD Carparks & regional bridge structures

Plate Bonding

the technique of strengthening a structure by bonding steel plates to the external faces by using epoxy or bolting. Construction & Maintenance skilled team have completed such works on the Sydney harbour bridge and other bridge structures across NSW.

Specialist Civil Services

Cappa Construction & Maintenance offer a wide range of civil services across multiple industries, our experienced team come from a background of civil engineering & Large concrete construction. This experience makes a big difference for many of our customers as our ability to provide civil works in conjunction with our remedial capabilities offers a more complete solution for the project we work on.

Civil services offered by Cappa Construction & Maintenance include:

  • Formwork & Concreting
  • Steel Fixing
  • Grouting
  • Pile Strengthening Works
  • Bridge Construction Using Fibre Reinforced plastic
  • Bridge and wharf carpentry
  • Retaining walls / seawalls
  • Precision-grouting
  • Rail shutdown Works

Joint Repair Systems

An expansion joint or movement joint is an assembly designed to safely absorb the heat – induced expansion and contraction of construction materials, Joints are essential in concrete as it allows slabs to move naturally so as to not crack under the weight.

joints are subject to extreme pressures that the concrete slabs undergo during the weight transfer of heavy loads and vehicular traffic.

Cappa Construction & Maintenance have successfully completed a wide range of joint repair systems, to the sealing of water reservoirs using Hypalon bandage systems, sealing of fuel bunds, Storage tank & the repair of bridge deck movement joints

Joint Sealing services offered by Cappa Construction & Maintenance include:

  • Repair of Expansion-joints
  • Bridge Deck Sealing
  • Hypalon Bandage Systems
  • Instillation of construction & movement joints
  • Sealing of Penetrations for fire safety
  • Chemical bund Sealing

Protective Coatings

Over time large reinforced steel & concrete assets can suffer damage from; carbon dioxide, water and chloride resulting in corrosion of steel and subsequently loss in structural integrity. To protect these structures, coating systems are an essential to protecting these assets and prolonging their service life,  

The most important step in any coating system is the surface preparation, Cappa construction and Maintamnce can undertake surface preparation works for both steel & concrete structures, this includes abrasive blasting, grinding, & preparation of surfaces using pneumatic and power tools,

We offer a wide range of services for the coating industry these include:

  • Nace Survey & Inspections
  • Preparation of surface
  • Application of anti- carbonation coating
  • Application of corrosion inhibitors
  • Application of cementitious coating
  • Application of epoxy coating
  • Application of elastomeric and flexible coating

Crack Injection

The methodology is used to seal cracks in concrete slabs, walls, masonry, concrete block foundations and other structures, before selecting the materials to used it is important to know if the crack is static or live. If the crack continues to move due to thermal or load conditions then a flexible material will be required in order to maintain the seal. Static cracks can be bonded and sealed by injecting with a rigid material such as epoxy resin.

 

Cappa Construction & Maintenance are experienced in completing both systems of repair for both epoxy & polyurethane type injection.

Cathodic Protection

Corrosion is an electrochemical process that involves a flow of electrons (the corrosion circuit). Cathodic protection is a means of controlling the corrosion of metal surfaces by stopping the flow of electrons. There are generally two types of cathodic protection systems – Galvanic (sacrificial) and impressed current. Galvanic systems employ reactive metals to protect the metal surface (commonly called sacrificial anodes and are normally aluminium, zinc or magnesium). Impressed current systems use an external power source to provide the electrochemical protection.

Cathodic Protection services offered by Cappa Construction & Maintenance include:

  • Sacrificial-anode Instillation
  • Impressed-current systems
  • Hybrid anode systems
  • Ribbon Anode Install
  • Marine Anodes Install
  • Sacrificial metal coatings
