Concrete CancerRepairs

Its the deterioration of a concrete structure or element resulting from the corrosion of the steel reinforcement within the structure.

What’s Concrete Cancer Repairs ?

Concrete Spalling/Cancer refers to the deterioration of a concrete structure or element resulting from the corrosion of the steel reinforcement within the structure.

Concrete spalling can be caused by concrete cracking, inadequate drainage, a lack of waterproofing, poor concrete placing practices including inadequate compaction and curing, poor concrete mix design, insufficient concrete cover over steel reinforcement, aggressive toppings such as magnesite, concrete cracking, or leaking concrete joints.

Causes of Spalling

(or concrete cancer)

Carbonation

This occurs as a consequence of concrete exposure to air borne chemicals. As a result, rusting occurs. The steel then expands forcing the surrounding concrete to crack and flake off.

Efflorescence

Efflorescence is caused as a moisure ingress and appears as a white deposit of mineral salts on the face of concrete walls and/or floors. The alkalinity of the concrete will drop and the internal steel reinforcement will corrode and spalling will occur.

Moisture

When water penetrates cracks in concrete, steel reinforcement rusts and expands up to seven times in volume forcing the surrounding concrete to degrade and flake off.

Salt Ingress

As concrete is porous, it allows chloride ions from coastal air to penetrate causing nodules of rust on the surface of the steel reinforcement. The rust nodules create internal stresses in the concrete, which result in cracks in the concrete.

Benefits & Process

Early protection and repair is essential to keep the structure healthy and guarantee that the problem doesn’t get more extense

OUR ADVICE
Preventive maintenance over the life of the concrete structure is more cost effective than remediation after deterioration progresses and, if left, accelerates to the point where the costs of repair are excessive.

Our process considers a tailormade solution for your
concrete repairing need. This is how we approach each project:

STEP 1: INVESTIGATE

We conduct professional investigations and diagnosis of the issue in order to identify the source and cause. Identifying the source and cause of the issue is vital in finding the best solution and preventing further problems. Once the cause of the issue has been identified and confirmed, we then determine the optimum repair system for each specific application. These processes are often performed under the guidance of highly qualified engineers, designers or architects.

STEP 2: RECOMMEND A SOLUTION

We access the most advanced technologies in concrete Restoration and Preservation from leading manufacturers worldwide to reinstate the structural integrity of any concrete structure. We strictly adhere to all manufacture and design specifications ensuring that the right system is used and applied correctly for your project.

STEP 3: GO THE EXTRA MILE

Longevity and continuing performance of the repair can be at risk if protection and preservation measures against future potential contamination threats are not adequately addressed. We also conduct operational and environmental investigations to ensure that future contaminant risks are specifically controlled using the most effective treatments available.
