Damp Treatment in North London

Cellar Conversions in Hemel Hempstead

We are able to turn damp and wet cellars into usable space.

The treatment used depends on the end use and the volume of water ingress.It will always involve some level of waterproofing. the extent of the waterproofing will depend on the end use of the space.

For simple storage space, which is needed to be dry, a simple tanking system may be sufficient.

If intended as habitable spaces or the level of ingress of water is measured in inches , then a drainage system will give the best results.

It is essential that whatever the waterproofing solution selected , the resulting space has constructural integrity as well as dry conditions. Our surveyors have the building knowledge to advise you on the correct solution for your special circumstances.

I have an Edwardian property. The cellar was initially damp but over the past 18 months the water ingress had got worse culmulating in a foot of water gathering over a 24 hour period and continuing to fill after bailing. It reached the point where we were bailing out every night after work and the water was seeping through the brickwork at shoulder height. The space was obviously unusable and the stairs were rotting.
After explorations from the insurance company they confimed it wasn't dirty water but the ingress didn't seem to be related to rainfall and was untraceable.
Peter from Johnson Ellis came and took the time to understand the problems we were having and worked out the best solution. He also brought the manager from Wykmarol on site to determine the best approach to give us a dry storage space. The work was completed quickly, they always cleaned up after themselves every night and I had no hesitation in giving them keys so they could come and go as they pleased.
I now have a dry cellar, with a new floor & walls & lighting, a pump and alarm. It's a functioning storage space I don't have to think about anymore which is exactly what I wanted. 'ENTIRELY SATISFIED , HATFIELD

See below a job recently completed by our company.

Typical cellar reclamation by Johnson Ellis Ltd.

A wet and damp cellar area , required by the client for useful storage space, this area contained 8 inches of water at the first site visit .

In this situation the client had drilled holes in the walls to let the water in, rather than risk the walls collapsing from pressure of water.

Tanking and proofing the cellar was unlikely to be effective ,owing the volume of water . A drainage system was required.

The cellar area flooded with up to 18 inches of water. The walls were very damp with heavy salt deposits.
