How do waterproofing systems work in the basement and what exactly are they? To answer that question, let’s first look at historically conventional basement waterproofing and how it is 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.

When the walls of the basement are built, there is always a gap left outside the walls which needs to be filled. Loose backfill is what is used to fill this void. No matter how well the backfill is compacted, it is still backfill and water seeks the places of little resistance.

Water will constantly ooze into this area. Sometimes, creating a problem is the drainpipe that gets full of silt contained in many systems when waterproofing a basement. The water is naturally bringing all sorts of suspension with it. Allowing these pipes to fill up, can result in an overload of the system, which can be catastrophic to the basement’s outside walls. 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. Basement waterproofing is also applied to the external walls of the basement to try and keep the water out. Usually this is called 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 protect the property water is controlled, collected and then made to pass through hidden drainage channels which are either natural drainage or sump pumps.

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,

While you are getting the house made you need to realize that waterproofing is more of an investment in the value of your house rather then an expense.
