Waterproofing is the most crucial concern due to less exposure to modern concrete technology. Avoiding this may increase the difficulty resulting in wall damped during flood giving a hideous look to your home.

The need for Waterproofing:

Our projects range from residential to high rise buildings. GJK is recognised for its quality workmanship and dedication to the industry.

The benefit of waterproofing is that the concrete shrinks when it becomes cold, especially in winter, causing cracks in the concrete to widen. Filling the cracks at their maximum width means that the resins used in crack sealing will not have to stretch. Here are four critical reasons why your building or construction needs waterproofing.

  • TO PROTECT INTERIORS FROM WATER DAMAGE
  • TO PREVENT ONSET OF HEALTH PROBLEMS
  • TO SAVE YOUR MONEY
  • TO PROMOTE LONG-TERM COMFORT

GJK specialises in protecting residential homes, commercial offices, factories and warehouses against water damage with recognised product know-how. With over 25 years of Waterproofing experience, no project is too big. Whether you are looking for waterproofing or any other service, call 1300857847 for expert advice.
