Concrete spalling (cancer) is widespread especially in coastal regions. Spalling is caused when cracks in the concrete allow water to ingress to the reinforcement. Water, when combined with carbon dioxide and chloride from salt near the coast, form an acid, and attack the reinforcement causing it to expand which in turn causes the top surface of concrete to chip, flake or delaminate. Many older buildings with rusted metal balustrades on the balcony have this issue when the rusted balustrade begins to crack the slab causing even more water to ingress into the slab, the results is as per explained above. CIB can provide a professional investigation and evaluation service prior to recommending a solution. Here the identification of the source of the problem and therefore the selection of the right product, is crucial in preventing a re-occurrence. We have so many remedial projects under our belt which has made us specialists in this field of works. CIB has a team of specialists in the area of concrete spalling who specialise in spalling repair and can effect a complete restoration to the structure by removal of damaged concrete, treating or replacing and retying reinforcement and applying a suitably designed concrete mix and finally apply a fairing coat to entire area as so no evidence of repair is visible. This leaves the repair looking uniform and as if it had never been touched.


Water leakage through building walls continues to be the single largest cause for construction litigation in new buildings. Litigation is all too often a long, tedious, expensive and unpredictable venture for owners and building managers. The litigation process often delays repair efforts which can exacerbate damage to finishes and building content, and, more importantly, the structure of the wall assembly. The cause of most water penetration problems is the lack of integration and coordination between the waterproofing elements of the various components within wall assemblies. This problem exists within the “gray” areas or transition spaces where one building element or wall assembly (such as a window or glass/metal curtain wall) terminates and another building element (such as a masonry wall). Although these transition areas constitute a relatively small surface area of the building wall, they cause the bulk of wall leakage problem.  

MASONRY WALL CRACKING - Under pinning & Brick Stitching

Building movement and often old building foundation practices contribute to Cracking in masonry walls which cannot be simply patched up and solved, as the cracking will continue because the issues have not been addressed. Two main rectification works are to be carried out when this takes place. Firstly we investigate to see if the structure is sinking or not, if it is sinking then under pinning must take place.
  • Mass Concrete Underpinning - 'Traditional underpinning,' the mass concrete underpinning method is nearly 100 years in age, and the protocol has not changed. This underpinning method strengthens an existing structure's foundation by digging boxes by hand underneath and sequentially pouring concrete in a strategic order. The final result is basically a foundation built underneath the existing foundation. This underpinning method is generally applied when the existing foundation is at a shallow depth, however, the method still works very well even at fifty feet (fifteen meters) deep. The method has not changed since its inception with its use of utilitarian tools such as shovels and post hole diggers. Heavy machinery is not called for in this method due to the tight nature of the boxes being dug. There are several advantages to using this method of underpinning including the simplicity of the engineering, the low cost of labor to produce the result, and the continuity of the structure's uses during construction.
  • Beam & Base Underpinning- The beam and base method of underpinning is a more technically advanced adaptation of traditional mass concrete underpinning. A reinforced concrete beam is constructed below, above or in replacement of the existing footing. The beam then transfers the load of the building to mass concrete bases, which are constructed at designed strategic locations. Base sizes and depths are dependent upon the prevailing ground conditions. Beam design is dependent upon the configuration of the building and the applied loads. Anti-heave precautions are often incorporated in schemes where potential expansion of clay soils may occur.
  • Min-Piled Underpinning- Mini-piled underpinning schemes include pile and beam, cantilever pile-caps and piled raft systems. Cantilevered pile-caps are usually used to try and avoid disturbing the inside of a building and require the construction of tension and compression piles to each cap. These are normally linked by a beam. The pile and beam system usually involves constructing pairs of piles on either side of the wall and linking them with a pile cap to support the wall. Again, the pile caps are usually linked by reinforced concrete beams to support the entire length of the wall. Piled raft underpinning systems are commonly used when an entire building needs to be underpinned. The internal floors are completely removed, a grid of piles is installed and a reinforced concrete raft is then constructed over the complete floor level, picking up and fully supporting all external and internal walls.
  • Underpinning by expanding resin injection- A mix of structural resins and hardener is injected into foundation ground beneath footings. On entering the ground the resin and hardener mix and expansion occurs due to a chemical reaction. The expanding structural resin mix fills any voids and crevices, compacts any weak soil and then, if the injection is continued, the structure above may be raised and re-levelled. This relatively new method of underpinning, has been in existence for approximately 30 years, and because it does not involve any construction or excavation set-up, is known to be a clean, fast and non-disruptive underpinning method.
Then to rectify the cracking Masonry walls, we use a method called Brick Stitching, if the building was no longer sinking then we could jump directly to this step of works.
  • Brick Stitching - Cracked masonry is best stabilized by bonding  (helical stainless steel bars) into appropriate bed joints or cut slots, in bricks, blocks or stonework with a cementitious grout. Tensile loads are redistributed along the masonry to minimize further developments of the crack which may occur with simple injection methods.


A very common issue throughout aging buildings and newly built complexes is the water issues from failing water proofing membranes
  • Roof Top
  • Basement
  • Balconies
  • Bathrooms
  • Planter Box
The old Standard for water proofing has come a long way and has changed due to so many issues that Buildings have suffered over the years. CIB has vast knowledge and experience with water proofing rectification, we are certified waterproofers as well. The market is filled with quick fix remedies from seal this and that, but the problem never gets addressed, this means you are back to square one in a few months time. Water proofing fails from various reasons:
  • In correct product application
  • Building movement, causing cracking in the membrane
  • Use of the wrong product for the intended purpose
  • The List goes on and on
CIB will assist you in Diagnosing the issue and will offer a comprehensive solution to rectify the issue. Call Us Today and see how we can help you.
