Interior Waterproofing

If you have a damp basement, it is important to address the issue as quickly as possible to prevent the growth of mold spores and possibly even to protect against structural damage. While exterior waterproofing is the most effective way to prevent moisture from getting in, many people are unable to choose this option due to the size of their property or because of their budget. If you fall into one of these categories, then interior waterproofing is a good option for you.

What is interior waterproofing?

First it is important to understand that interior waterproofing isn’t exactly waterproofing. Moisture can still seep in from the outside. A more accurate name for this technique would be interior water control. While water can still come in, it will be quickly diverted through drainage tiles which are installed underneath the floor.

By installing a backwater valve, you can protect your home from flooding as this valve helps to prevent sewer water from backing up through your toilet or sink during a heavy rainfall. A backwater valve is particularly a good idea if your home is on a slope or if you live in a flood prone area.

For water that gets in via a leaky foundation, you can effectively divert in away by installing a drainage system that includes a sump pump, rubber walls, and weeping tiles. With this system in place, water can easily drain away from your home without causing damage to the walls.

During interior waterproofing, it is also usually recommended that any basement windows are sealed. As well, if your basement drain has become clogged or smells of mildew then a cleaning and/or replacement may be in order.

What are the advantages of interior waterproofing?

For many homeowners, one of the biggest advantages of waterproofing from the inside is that fact that it can be considerably less expensive than exterior waterproofing. Exterior waterproofing requires excavation around the entire foundation which means not only is it more labour intensive but it also requires more specialized equipment.

And that leads us to the second major advantage of interior waterproofing – it does not require excavation. Not everyone’s home is suitable for exterior excavation. If you have a very small lot, live in a historical building or even if your neighbour’s home is too close to yours – then excavation may not be possible. Interior waterproofing allows you to divert water without disturbing the property surrounding your home.

Who should choose interior waterproofing?

As mentioned earlier, exterior waterproofing is by far the most effective method to keep your home dry but this method is not suitable for every property or every budget. If you have noticed dampness in your basement and are unable to opt for exterior waterproofing, then interior waterproofing is something you should consider.

But why wait until you have water in your basement? Taking preventative measures is a smart idea especially if you live in an area that is prone to flooding.
