PROBLEMS IN CONVENTIONAL & CHEMICAL WATERPROOFING TECHNIQUES
  • No treatment is available to fill up the honeycombing that is present in most concrete slabs, especially sloping slabs. This is a primary cause of leakage as trapped air gets heated during the day, expands and escapes making way for the entry of water.

  • Thermal expansion and contraction (occuring daily from mid day to night) of concrete and of masonry are not dealt with. This is the second reason for the appearance of cracks which cause leakage of water.

  • Exposed horizontal surfaces of concrete unless painted over, get eroded and appear sandy due to the effect of dew which is acidic in reaction today.

  • Masonary parapets crack at regular intervals through which water seeps in.

  • Rods, pipes, wires projecting out of the concrete/masonry structure crack at the junction due to differential thermal expansion. No proper treatment is available to overcome these cracks.

  • Chemical waterproofing blocks the porosity of the treated surface, preventing the structure form breathing air and water vapour. This trapped air within the coating expands in the hot sun, forming bubbles which ultimately burst and peel off the surface, leading to leakage.

  • Most commercial additives to cement make it strong and rigid. In dry conditions, this resists thermal expansion, which in turn cracks the surface through which water seeps in.

  • Chemically treated surfaces get ruptured with normal movement over them.

  • In existing buildings cracks which appear especially on the West and South walls should not be filled by gravity or direct pump injection of cement slurry alone as this makes the structure rigid and it tends to give way to cracks elsewhere.

  • Waterproofing of expansion joints by simply putting flexible fillers grip only at the surface. This can easily rupture and allow rain water to enter.

  • Water tanks made of cement concrete get eroded from inside by the chlorine present in water.

  • All types of windows, especially those made of aluminium are very difficult to waterproof where rain and wind pressure are the maximum, and especially if no chajja is provided over the window.

  • Existing bathrooms, open balconies and terraces which have developed leakages from the floor, walls or pipes are normally waterproofed by ripping off the tiles. These can be waterproofed by our system at a very competitive rate, in two days without disturbing the tiles.

  • Curing is intermittent.


OUR FOOLPROOF WATERPROOFING SOLUTIONS FOR NEW & OLD CONSTRUCTIONS

  • Honey combing in RCC structures and masonary are injected with cement slurry pneumatically at low velocity but high pressure after vacuuming.

  • Thermal expansion and contraction of concrete and of masonry is existing buildings are also injected pnuematically with a flexible cement mix.

  • All exposed surfaces of concrete and masonry are ocovered with a flexible layer of cement mortar which is resistent to a pH of 5.5.

  • Cracks appearing in masonry parapets of existing buildings are pneumatically injected with a flexible cement slurry. For new buildings, compaktuna must be added to the mortar.

  • Rods, pipes wires projecting out of the concrete/masonry structure are joint by a graduated joining process.

  • Compaktuna/silicones mixed in cement mortar allow the structure to breathe by allowing air an water vapour to move in and out of the structure, but do not allow water (having a larger molecular structure) to enter.

  • The cement mix can expand and contract to a great extent in heat/cold conditions tolerating about a million cycles.

  • As the thickness of the waterproof layer is 2 to 3 cms. and it even penetrates the concrete/masonry, there is no question of failure even if pedestrian traffic moves on the surface.

  • In existing buildings, cracks which appear, especially on the West and South walls are filled by pneumatic injection of a flexible cement slurry allowing for thermal expansion.

  • Expansion joints are fully filled with a highly flexible silicone mix which grips the opposite surfaces by a deep and penetrating bond, bottom and top cladding is provided.

  • Water tanks made of cement concrete are protected by a 2 cms. layer which withstands a pH of 5.5 to 14.

  • Existing bathrooms, open balconies and terraces which have developed leakages from the floor, walls or pipes are waterproofed by our system in two days without disturbing the tiles, at a very competitive rate by a water tight barrier process.

  • Curing of the waterproofing is done mechanically and continously, even on a sloping slab for a period of ten days.
