Damp Proofing

What is the best method of damp proofing my porch?

Anonymous user 23/02/2024 - 3.39 PM

Hi there, I have recently bought a house with a single layer brick porch that has been rendered on the outside. With the cold and wet weather the porch has been getting more and more damp with condensation and patches of mould have been appearing on the internal walls. I have done some research and am struggling to find a definitive answer on how to remedy this. The external rendering is to the ground so I assume cutting that back would improve things but I have also read that ventilating the porch would help reduce condensation. How effective would this be? Both the internal and external door need replacing as neither fits properly to create an efficient seal, do both of these doors need to be external grade to minimise condensation in the porch area? Any help or advice would be greatly appreciated!

Are you a tradesperson and able to answer this question?

Insulated plasterboard and and air vent should help things and if the brick is exposed internally and no dpc is present also you just as well inject it

some simple advice treat the problem as penetrating and Rising Damp storm Drive the exterior for penetrating damp this is a breathable cream easy to apply and creates a barrier for rising damp . Use dryzone cream . Drill out the motor one brick above the bottom course that will cure any Rising Damp look this up and it plenty of information out there are also so a vents will help it dry out it will take up to 6 to 12 month to dry out depending on the temperature inside and the ventilation system

Chances are it's the external render causing the problem. Baton and dry line will only go mouldy. The render need to be removed to about 8 inches above ground level, a chemical damp course needs to be injected and then the render brought back down to being at least 6 inches above ground level and finished with a bell lip. You then need to remove internal plaster probably only to a metre high and replanted with an anti sulphate cement based render. This will stop further damp being drawn in and allow the brickwork to dry out without leaving it exposed for the next few months. You can dry line instead of plastering but a chemical damp course and dry lining alone will not solve your problem. You need to get that render sorted.

Consult with a specialist who will survey the construction and let you know exactly what needs to be done. Hard to give any accurate advise without seeing the property
