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 imagine how a basement is first built, when the house it is sited in was first conceived, then basically the following happens. A big hole in the ground is dug, the footer or foundations are laid, the walls of the basement are built and then the rest of the house follows.

 The important point to note is the first one in the list above – that big hole in the ground.

 The construction of basement walls invariably leaves a void on the exterior which requires backfilling. Loose backfill is used to fill in the gap. Well compacted or not, introducing a huge pile of loose backfill is going to cause problems. Water will always flow in the path of least resistance.

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. It’s natural enough, the water is bringing all sorts of suspension with it. When these pipes get filled the system overloads and a lot of water pressure gets applied to the outside walls of the basement. So while the walls of the basement may be waterproofed in some way, water, as you probably already know, will usually find a way through the tiniest of gaps.

 This type of problem doesn’t usually go away because the pipes that are supposed to take away the excess water gradually worsen over time.

 A lot of the time a huge mistake is made by not providing access to these pipes. In an attempt to keep excess moisture out basement waterproofing also can be put onto the outer walls of the basement. 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

Choose a reputable basement waterproofer when protecting your home, remember it is economically foolish not to waterproof, because the increased value from waterproofing will definitely exceed the cost of the waterproofing.

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.
