What causes these major cracks and faults?
There are several factors, both environmental and man-made that affect the structural integrity of a building. These include:
- Environmental damage: The equatorial climate we live in leads to thermal expansion and contraction of concrete which cracks not only in terraces and external walls but also along balcony and parapet walls. Rain water then seeps in from these cracks entering the beams and walls and further causing damage and corrosion. The problem is further exacerbated when conventional construction techniques and unskilled labour have been employed.
- Improper waterproofing: Damp patches, musty smells, dripping bathrooms or kitchens all indicate improper water proofing in the wet areas of homes and improper treatment of external walls. Water seepage works its way through the structure from within and if unchecked can cause major damage and weaken the structure.
- Vegetation: Birds sometimes deposit plant seeds onto building's parapets and terraces where they germinate and take root. The roots can go deep into a structure and cause cracks. As the tree grows, the roots further widen the cracks and cause crumbling of plaster and sometimes can even cause wall collapse.
A solution to these issues requires a new age, technically sound product, which can address all these issues. One such product is R04 Roff Crete Repair - a flowable self compacting micro concrete for structural repairs. Roff Crete Repair is a specially prepared ready-to-use grey powder which requires addition of water only onsite, to produce a free flowing, high strength concrete which has fine aggregates and ability to penetrate into the recesses of concrete members and behind the reinforcement of the member under repair. Roff Crete Repair is a blend of selected Rortland cements specially graded micro fine aggregates, fillers and a range of fluidifiers. Structures under repair often require building up with high strength concrete.
The Roff Crete Repair offers many benefits including being flowing and self-compacting, therefore, not requiring compaction. It can be pumped or poured into restricted locations. It is also non-shrink, and does not produce shrinkage cracks along the line of old and built-up concrete. Not only does it develop high initial and ultimate compressive strength but is also impermeable, durable, and forms a good bond with the parent concrete.
So, before you decide on what colour to paint the walls, get the cracks in the walls repaired using a quick and long lasting solution like Roff Crete Repair – your home will not only look radiant, but will also last for many years to come.
