Water Proofing Your Home
One of the major concerns when purchasing a home I tend to come across is whether there is any dampness in the basement and what remedies are available. It is a fact that with older homes and especially block foundation water will find a way in. Key things to look for when inspecting the basement are:
1) water (obvious)
2) mould
3) efflorecense- looks like salt staining (may not be an indicator)
4) musty smell
5) damp carpets
How to avoid water in your basement?
The best step to take first before undertaking major work is by properly grading the land around your home so that water flows away from the walls. Also make sure that your eaves are free and clear of debris and that the downspout works properly and leads far enough from the house. You will find that these two steps will fix 80% of the moisture problems that people encounter.
What next? So grading and the eaves are not an issue. There are two other methods available to address water problems and they are either from the inside or the outside. Excavation is the most common method of water proofing your home. It involves digging around the house (or areas affected by the problem) down to the footings. After which you need to lay down perforated tube call weeping tile near the footing. This helps carry the water away from the house. Membrane is then used to protect your walls from getting wet. What this does is basically protects the foundation wall being directly exposed to water. If any water does get in between the membrane and the foundation it will travel down the wall because of the membrane's "bumps". Another precautionary step is to apply blue skin. It is an adhesive and a plastic layer that some contractor install between the membrane and the foundation wall. After the material has been applied the next step is to fill the trench with enough gravel to properly drain the water from the soil down to the weeping tile.
When water proofing from the inside it is basically the same as from the outside. The same materials mentioned above can be applied here. The major differences are there is not such a massive trench to dig. Instead a smaller trench will be dug just enough for the weeping tile to be installed and a little gravel. The membrane will be exposed as well. Of course you can always build out the wall to cover the membrane. Additionally, to properly water proof from the inside a sump pump will have to be installed. This collects the water from thew weeping tile into a basin and pumps it out once a certain level has been filled to the outside.
There are MANY factors that go beyond the scope of this article in regards to determining when and how to waterproof your home. Keep in mid that sometimes water that shows in the basement could be from a window in need of repair or even a leak in the roof of the house. This guide is meant to give you an idea as to what the average home owner can expect. For any issues relating to water it is important that you contact a qualified contractor. Please follow the link provided below that will guide you to CMHC (Canadian Mortgage and Housing Corporation). They too provide a great resource for home maintenance and repair.

TIP: If you see that you neighbour is going to water proof their home it might be a good idea to have the contractor quote you as well. If the homes are close enough you and your neighbour can save some money since only one trench might be dug. The problem is that sometimes once your neighbour has water proofed their home the soil may become disturbed and may direct water towards your home. In which case you may find yourself calling someone to waterproof your home next! PLanning in advance may help you nd your neighbour save money.
