HRV (heat recovery ventilation system) This is the best way to control condensation

If there are no existing waterproofing systems that will work, I will design one.
This under pavement room, not vaulted, was not of sufficient structural strength to withstand a tanking system or suitable for a cavity membrane system.

10)Polyurathane resin injection. Sometimes the foam comes out of unexpected places!
The resin "chases" water and dampness through the structure.

9)Deemed as rising dampness by others, treatments had no effect.This is a perfect example of hygroscopic dampness.The moisture is comming out of the air and is being absorbed by defective plaster.Seen mostly around new electrical fittings.

8) An example of a humidity controlled , input and output fan to control black spot mould. It is almost silent, with low energy consumption, fully automatic and tamper proof.

7)Not all walls require tanking. Here is an example of a paint on latex slurry. This must only be done in combination with drainage systems.

6)This was a 1st floor deck with sky lights that had leaked since construction, ten years earlier. I installed a waterproof membrane on the deck and then fitted new 25mm glass and sealed them. Others completed the tiling.

$5) this vault had been "tanked" twice previously by others, both failed!Through investigation I found that the "leaks" were in fact CONDENSATION only. The installation of fan solved the problem at a fraction of the cost of tanking .$

3) Underpavement toilet. Water comming through the vault and floor, complicated design and with plumbing passing through the walls.

1) Under pavement vault, Oxford street, London. To be used for document storage. At present leaking badly

Damp Proofing

I have terrible damp issues in my flat Chris came round and identified the problem as condesation and fitted a special fan system which has helped alot, he was reliable friendly and extremly trust worthly with his advise. the cost of the work was also much better than i was thinking it could have been, he also wrote a report which has helped when looking for other tradesmen to redecorate 07 Feb 2013 TOM, N8
