Pressure grouting waterproofing
Pressure grouting waterproofing is also commonly know as chemical pressure grouting.We have discussed before many traditional old methods and modern advance methods. This a traditional old method but the materials used for waterproofing keeps on changing. New advance chemicals with various properties are easily available in the market today.
Pressure grouting waterproofing mainly contains materials like Polyurethane and Epoxy. These materials are injected into the cracks cause in the concrete slab or concrete structures.
The materials like polyurethane are very flexible as compared to other materials that are being used in the other methods. The more flexibility the material has the more durable is the waterproofing.
The biggest advantage of this method is that it can be used in dry as well as in wet surfaces. This waterproofing method is used in various cases such as:
- Rooftop slab structures like podiums and carparks
- Joint of different pipes
- Pipe junctions and manholes
- Weeping hairline cracks
- Lift shaft walls and floors
This method is also carried out on large areas such as reservoirs, dams, waste water treatment plants. The whole process is easy, and availability of materials is not an issue.
It’s not a high cost method and the durability is much longer as compared to other methods.
Mainly the cost depends on the material being used. Better to carry out this method when you see small cracks, don’t wait for the cracks to get widened and to spread out. There are many reasons for the formation of the cracks such as air bubbles inside the concrete, unwanted movement, sudden temperature changes, low-quality concrete cement usage, etc.
This is not a pre-waterproofing method. It is only carried out when there are leakages and cracks. Proper inspection of the damaged area is important.
There are various medium to large scale companies which have trained professionals for this job.
