Fixing Rising Damp
July 13th 2006 01:55
If you’re damp course is ineffective or non-existant, be prepared for a costly renovation. The good news is that many rising damp problems can be fixed by some simple home DIY maintenance. You should give these ideas a go before you start ring around for professional damp course help.
1. Clear around and under the house. This will mean grabbing a torch and crawling in that void that exists between your house and the ground. Remove any soil, rubbish or debris which impedes the flow of air or which bridges the damp-proof course. All of this rubbish and debris may be causing a link for the ground moisture to rise up and penetrate through your floor and into the upper walls. Get out into the garden and give any vegetation planted close to the walls a good trim back. Heavy, thick vegetation encourage moisture to rise from the ground and up towards your house. Give the adjacent vegetation will also allow damp that has collected under your house to dry out.
2. Get outdoors and check the level of an concrete paths adjacent to your house. If any of these concrete areas directly against a wall and is above the level of the damp-proof course then ground moisture may be penetrating through the concrete or running off and being absorbed by the walls of your house.
3. Beyond checking the any concrete or paved areas adjacent to your house, ensure that all water falls away from the walls and does not drain into the foundations. This may occur as a result of rainwater heads being too small or adjacent ground surfaces sloping towards the house walls. Any poor drainage problems can be solved by the installation of agricultural drainage lines, laid in gravel-filled trenches and connected to a suitable point of run off.
If you are convinced that you do indeed suffer from rising damp then there are a number of companies out there that offer a variety of ways to fix a rising damp problem. There appear to be a lot of companies offering a chemical spray treatment of one kind or another that is supposed to soak into the walls and prevent any moisture from entering the brick work. This seems to be one of the cheaper and simplest methods of solving the problem. However, it is questionable how efficient a chemical solution will be for rectifying rising damp. The chemicals rarely penetrate very deep into the brick work and can in fact prevent the moisture from evaporating out of the brickwork. The best solution is to attack at the heart of the problem which means reapplying a boundary between your house and the ground moisture which is leeching upwards. This entails looking at the details of your current damp-course and taking measures to either repair it, replace or install one if one does not already exist.
