best economical and durable Basement Waterproofing systems
When it comes to waterproofing your basement there are three common methods. these are exterior waterproofing, interior weeping tile, and crack injection.
The most effective waterproofing method is exterior waterproofing as it’s the only method which fully waterproofs a home’s foundation. The exterior wall is sealed and a French drain system, also know as a curtain drain or footing drain is installed. if this method isn’t an option due to access to the exterior or your budget, then the interior weeping this is recommended. Interior waterproofing methods are usually used when the exterior is inaccessible like we have with cramped yards here in Toronto, or when cost is a factor.
The interior method utilizes drainage in the basement as a way to control the water by removing it with a sump sump The crack injection is more of a temporary band-aid solution and is recommended for just small cracks. The water could still sleep into the concrete behind the cracks with this method and the foundation may erode over time , The best way to find out which type of system you need is to contact a professional waterproofing company.
why some Exterior Basement Waterproofing systems fails?
Not all basement waterproofing repairs are created equal. There is a big difference between a basement waterproofing professional and a general handyman who is a novice. We are not saying that someone who is mechanically inclined and has a little know-how is not capable of attempting a repair. We have just learned over the last 50 years that amateur and do-it-yourself repairs will generally fail over time.
1. The repair never took effect from the outside:
Interior surface patching methods are prone to leak again because the water isn’t stopped at the source – on the exterior of the foundation.
2.The materials used are not meant for waterproofing:
This one is particularly true for exterior repair types. Before the advent of modern waterproofing methods, a common way to waterproof a foundation was to excavate the entire wall and apply tar to the surface.
3.Poor water management on the exterior:
Let’s face it – if you have water sitting against your foundation, the chances of your waterproofing repair failing increases tenfold.

Another way of distinguishing high quality insulating materials is to cut off on the part of the insulator, which does not cover the outer layers. If black stains are not transferred to the hands, it is known that in this type of rubble, high quality polymeric materials and bitumen are used. The quality of the insulation is good. The fact is that the use of adverse environmental imperatives in buildings has caused many problems, such as demolition of parts of the building and a lot of costs for its inhabitants.
