Concrete Repair

CCL can offer a wide range of concrete repair services, from concrete remediation and resin injection, to movement joints.

Given the huge number of concrete structures that surround us today, it is easy to take concrete for granted as it enables us to live the lives we do in our evolving urban landscapes. Just like us, concrete needs to be maintained as it is affected by the stresses and strains of everyday life.

Defective, blown, or poor-quality concrete can lead to serious structural defects, and even worse further down the line if it is not maintained. Surface cracking is normally one of the first signs of such defects, leading to structural cracking and steel reinforcement corrosion, which needs to be halted and treated.

CCL has an extensive history in carrying out concrete repair and protection to a wide range of existing reinforced concrete structures. Utilising its vast experience in this area, CCL only use the best and technologically advanced products on the market, to repair and protect a wide range of existing reinforced concrete structures. Typically, these are exterior building façades, internal columns, pillars, and slabs, through to reservoir roofs and multi-level shafts.

Services offered include:

  • Grouts
  • Movement joints
  • Restoration mortars
  • Masonry repairs
  • DPC injection
  • Hypalon bandages
  • Protective coatings
  • Anti-graffiti coatings

There are numerous products and systems available for many concrete repair applications, these include:

  • Reinforcement corrosion protection and bonding primer
  • Repair mortars
  • Pore filler and levelling mortar

Corrosion protection and bonding primers are used for bonding concrete repair mortars to any existing cementitious or steel substrates, as well as providing additional corrosion protection to reinforcement steel. Whereas repair mortars are specifically designed for restoring or replacing the original profile and function of the damaged concrete; they help to repair concrete defects, improve appearance, restore structural integrity.

When concrete needs to be coated or levelled, special mortars are necessary to fill the surface pores. Pore fillers and levelling mortars are thin layer renders, designed to repair minor defects, such as repairing pores and honeycombed concrete.

Typical areas of application include:

  • Exterior building façades
  • Internal columns and pillars
  • Slabs, through to reservoir roofs and multi-level shafts.
Concrete Repair

Although movement joints are commonplace in new build construction on podium roof decks etc, these are often prone to failure if not installed correctly.

CCL can offer various solutions for repair or replacement of failed movement joints, dependant on the amount of dynamic, lateral and longitudinal structural movement expected, or designed as dictated by the structural engineer.

Grosvenor House

“Grosvenor House was a complex domestic build located on a site that was very wet. The subterranean ground conditions were running sand and a potential ground water pressure of 5 tonnes per square metre expected to the RC basement structure. With this in mind we needed to have complete confidence in the company who would be providing the water proofing solutions, which we found in CCL. From their initial proposals all the way through to completion they were professional, helpful, thorough and cost effective. It is imperative as a luxury house building company that you have a watertight structure below ground. Due to the CCL solutions and implementation, there have been no such issues that have arisen since completion and that is invaluable.”
