What is Waterproofing A Basement All About?
The basement waterproofing systems and their working.
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.
That big hole in the ground, the first on the list above is important to note.
The construction of basement walls invariably leaves a void on the exterior which requires backfilling. Loose backfill is used to fill in the gap. 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. The conventional way of waterproofing a basement provides some form of drainage pipe for this water to drain away, but the problem with this is that often these pipes get silted up. The water is naturally bringing all sorts of suspension with it. 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. 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.
The problem of this type is not easily rectified. The reason is that the pipes which are supposed to take away the excess water are gradually getting deteriorated and worsen over time.
A huge problem is that often there isn’t 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 also called a tanked system.
The drained cavity basement waterproofing system is a better system that works by getting rid of water pressure in the walls. Water is controlled, collected and allowed to flow through hidden drainage channels either to natural drainage or to a sump pump where the water is removed away from the property.
Waterproofing a basement is reputedly a better system when they are installed internally, have easy access ports for removing any silt and can be applied to basements where traditional tanking or other methods have failed but with minimal disturbance to the original basement.
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.
