Waterguard Magic: Biochemically Modified Waterproofing Coating

 

 

Concrete has the potential to be one of the most long lasting materials in history – the Egyptian pyramids in Ancient Egypt were also constructed from a primitive form of concrete, and they’re still standing strong. Then, why shouldn’t our homes, or any other concrete structure, exhibit the same longevity. The number one arch enemy of concrete is water. Not only can water create harmful health risks with the growth of mould and mildew, and create numerous problems for homeowner’s foundations, but it can also be a carrier for salts and chlorides that can damage reinforcing steel in concrete, leading to spalling and cracking.

Waterproofing is basically a process designed to prevent water from penetrating into a structure. Typically, waterproofing is performed in various layers and stages to create multiple barriers so that water cannot penetrate the structure. A structure is waterproofed using membranes and coatings to protect contents underneath or within, and the structural integrity. Thus, protection from weather, seepages from ground and vertical travel of water in a structure can be well-protected by the correct application of waterproofing system.

Factors Affecting A Building

Every building can be referred to as a living thing, as it also experiences the problems of deterioration if proper care is not taken and maintenance is not done. In this way, some natural factors like air, water, climate, wind and humidity govern the life of building, apart from the occupancy load. Water (through humidity and rains) is the prime source of degrading or harming a structure, right from its foundation to its plaster if the structure is not well-protected from it. Water through its capillary action enters and hampers the strength of concrete, thereby making it susceptible to corrosion. This can be observed in building through the development of cracks on plaster, rot formation on walls and presence of moisture on ceiling.

The degradation and harms lead to expensive structural repair works, damage or loss of interior finishes and goods, operational downtime, or serious impact on the internal environment from dampness and condensation.

The selection of an appropriate waterproofing method, the project specific design of the chosen waterproofing system and its correct installation on site are key elements in minimising the Total Cost of Ownership (TCO). A waterproofing system typically amounts to less than 1% of the total core constructions cost, yet the selection of a high quality waterproofing solution can easily save this amount or more, in future maintenance and repair costs over the service life of the structure.

The conventional waterproofing method is either a liquid applied waterproofing coating or a preformed elastomeric membrane, where they can temporarily help to reduce water and within a period of time those coatings or membranes are delaminated. Since they are unable to penetrate and rather coat the surface, it is more like putting a band-aid on the problem instead of sealing from within.

 

FAIRMATE provides full range of technologies and solutions for waterproofing of structures. The company has launched a revolutionary product WATERGUARD MAGIC, which is a biochemically modified chemical solution that provides long-term waterproofing and durability benefits to concrete. It penetrates concrete and reacts with free calcium and water to form a calcium silicate gel complex in cracks, pores and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions. WATERGUARD MAGIC will seal existing leaking cracks up to 2.00 mm. Further, in the matrix, the product remains reactive when in contact with water to provide autogenous healing properties to future hairline cracks.

 

 

 

 

Advantages of WATERGUARD MAGIC are as follows:

  • Permanently seals cracks up to 2.00 mm.
  • Reseals future hairline cracking.
  • Reduction of chloride diffusion coefficient (ASTM C 1202) by
    89% to 3.5 (10-12 m2/s).
  • Water permeability (DIN1048) is reduced by 70% to 5.0 (10-12 m/s) at 10 kg/cm².
  • Increases surface hardness from 6 to 8 on Moh’s scale.
  • Reduces scaling in freeze-thaw environments by 89% at 50 cycles.
  • Allows 84.1% moisture vapour permeability.
  • Non Toxic - Certified suitability for potable water.
  • It is giving 100 years warranty with no further maintenance cost.
