Are you suffering from dampness or flooding of your basement?

It is not unusual that the older type of houses in South Manchester and Cheshire, for example the Victorian semi or terraces, suffer from dampness - particularly in the cellar where the house is nearest to the water table. Chestergate specialises in controlling the water that can penetrate your cellar by using time-proven unique systems designed to protect the internal fabric of your cellar or basement from dampness by applying a system that will allow equalisation of water pressure ensuring walls and masonry can breath naturally. Dampness is the main reason many people leave their cellars or basements unused. Anything which is stored there will become mouldy and electronic equipment will be damaged. In order to utilise this potential extra luxury to your house, dampness prevention is of course very important. We can transform what was once a damp, useless space into a whole new area to your home which you can be proud of for years to come. For a free no obligation quotation call now on 0161 929 5858

About the system we use to protect your basement from flooding

At Chestergate RBS Ltd we use the Delta Sump Pumping system. The pumping stations collect ground water and control management systems are installed under the cavity drainage membrane.

The ground water enters the pumping station through the installed water control management system, it is then pumped away by a float activated submersible pump to an external drain at ground level.

To enhance the reliability of this system, various accessories are available including high level alarms, battery back up systems, and non return valves.

The back up unit is continually being trickle charged under normal conditions. Once mains power has failed, the unit will automatically switch over to battery power to enable the pump to run when required. The power pack will pump approx 8,100 litres on back up or switch on up to approximately 49 times on a 60 second cycles.

High water level alarm

This system will warn if a high level situation occurs. It is supplied with a rechargeable battery so the alarm will still sound in the case of mains power failure. An optional remote alarm can be fitted if required.

Quite simply water will always fall to a low level point in your basement due to gravity. Using our system water will be removed through the sump pump station and flooding can be eliminated.

The heart of the system is the Sump Pump Station. This is why we offer a number of design options, each one providing greater protection and backup should any unforeseen problems occur.
