How Does One Find Out How to Waterproof a Basement?
What are basement waterproofing systems and how do they work?
For answering that question it will help to first take a look at historically conventional basement waterproofing and the way it was supposed to work.
If you can see a home being built the contractor first surveys the lot using the blueprints for the home to be built; then he sights out the lot to find out the best place to start digging and grading the property, then he lays the footer or foundation and begins building the basement walls, lastly the balance of the home follows.
The important point to note is the first one in the list above – that big hole in the ground.
When the walls of the basement are built, there is always a gap left outside the walls which needs to be filled. This void gets filled with loose backfill. The problem here is that water looks for the path of least resistance, and you’ve just given it just that with a huge pile of loose backfill, no matter how well it’s been compacted.
Water will continuously seep into this area. Sometimes, creating a problem is the drainpipe that gets full of silt contained in many systems when waterproofing a basement. As the water comes it brings all sorts of suspension with it and that is to be expected as it is natural. The system can overload if the pipes get over-filled and then the pressure of the built up water would be concentrated on the outer basement walls. If there are crevices in the walls, water will push through even if the basement walls are waterproofed.
This kind of situation is persistent because the tubes that should drain the excess water eventually deteriorate.
A huge problem is that often there isn’t access to these pipes. To keep water out of a basement waterproofing is also applied to the external walls. This is often referred to as a tanked system.
A better basement waterproofing system, such as the drained cavity basement waterproofing system, works by getting rid of the water pressure on the walls. To move water away from your property; it first must be collected and sent through drainage channels to a sump pump or a natural drainage field.
Waterproofing a basement is a better system when they are installed internally and have easy access ports for removing the silt etc. It takes minimal disturbance to the original basement where traditional tanking or other methods have failed.
So to summarise, a good basement waterproofing system will:
- usually be a permanent or long-term solution
- stop both ways by which water can enter through the walls and up from the floor
- not disturb landscaping, decks, patios, driveways, etc
- usually be an approved waterproofing method for home loans
- often be substantially cheaper than other waterproofing methods
You want to be sure to choose a reliable waterproofer for your home, keep in mind that it will greatly increase the value by far more than what you initally paid.
In conclusion, you want a basement waterproofing system that will deliver:
- a permanent or long term fix
- stop water through the floor and walls
- not disturb the exterior appearance of your home
- an approved method by home loan lenders
- more affordable than other methods
You should look at waterproofing not as an expense but as an investment in the value of your home.
