The MPS System

This is the centrepiece of Hydrotech’s technology. It is a proprietary electro-osmotic system directed at drying out subterranean masonry structures with capillaries, such as concrete and brick, and maintaining them in a permanently dry state. MPS can be used both in new structures and to dry out basements and tunnels that already suffer from a chronic water seepage problem. This is evolutionary technology developed from the long established principles of electro-osmosis which works through a series of low voltage pulsating charges.

Other methods of addressing water seepage in use in the building industry today can be characterised as temporary solutions to a problem for which there has until now been no apparent permanent solution.

Concrete and brick masonry structures consist of a mass containing capillary formations. Water may penetrate structures in a multitude of ways, the simplest form of which is as a result of gravity. Water can also penetrate structures through capillary synthesis, very much in the same way as plants and trees receive and distribute water to smaller branches.

MPS is utilised for transporting water encapsulated within the capillaries out of structures, as well as permanently preventing the penetration of water into structures. A control unit produces a series of low voltage electrical charges which are passed through electrodes in the form of probes or wires strategically placed within portions of the ceilings, walls and floors that are wet.

By placing a low voltage charge between negative and positive electrodes within a structure, the water becomes ionised. Ionising the water molecules within the capillaries causes the water to travel towards the negative electrodes to be evacuated at an optimum site, while at the same time preventing the water from intruding back into the structure. The wet area will quickly dry up and remain dry.

The movement of the ionised water in the capillaries is both stronger than gravity and capillary synthesis. Research has established that this technology is capable of preventing the penetration of water in a high-pressure environment of 600 metres head (60 bars).

MPS System Benefits

  • There are numerous benefits to be derived from the MPS system compared to the more traditional barrier coatings and penetrates.

  • MPS system provides a permanent solution to waterproofing.

  • MPS system can be retro-fitted to existing buildings and structures.

  • MPS system is both cost effective and simple to install.

  • MPS system is flexible and can be installed from the exposed inside of a structure, negating the need for expensive exterior excavation work.

  • MPS system is a low voltage system with minimal running costs requiring approximately 10 Watts of power for a 1,000m2 treated area.

  • MPS system is environmentally friendly with no harmful emissions or waste.

  • MPS system is safe to use and has no damaging side effects for a structure and will not alter its material composition.

  • MPS system is touch-safe.

  • MPS system prevents penetration of waterborne bacteria.

  • MPS system reduces the relative humidity in areas where it is installed, reducing corrosion to exposed mechanical equipment and other fixtures.

  • MPS system reduces corrosion of steel reinforcement within a structure.

  • MPS system prevents peeling paint, mould, mildew and foul smells.

  • MPS system stops efflorescence.

  • MPS system enhances the bonding properties between old and new concrete, an important consideration in the renovation of deteriorated (cracked) concrete.

  • MPS system improves a structure's insulation, thereby reducing cooling and heating loads.

  • MPS system reduces or eliminates the need for drained cavities in dry-wall construction resulting in greater space utilisation and reduced construction costs.

  • Mechanical crack remedial measures are extremely effective and easy to implement in conjunction with MPS system.

  • MPS system has potential to reduce the thickness of diaphragm walls to its structural minimum providing a significant cost saving for new projects.
