So you got your foundation cracks sorted and the repair was successful. Is that it? Short answer is no, you still have a bunch of things to do to make sure it never happens again. While it may not really be possible to control what goes on under the soil or control the weather, there are things that you should definitely do to make sure that, to a reasonable extent, you are not repeating the same things that might have led to the damages in the first place.
Here are a few tips to keep your foundation cracks permanently sealed
- Be vigilant
Water and excess moisture can still sink or erode the soils out from under your foundation, so make sure no water is settled there. For the most part, rainwater and running plumbing are major contributors to wetness, if you find plumbing problems, broken pipes, leaking drains or overflowing sumps, make sure you get them fixed before they soak through, all the way to the foundation and loosen it or worse, swell it.
- Rainwater draining
Harvesting rainwater is a good thing, but where is all that water going? Traditionally, it is directed down, back into the ground to replenish the groundwater, but if it runs under the house, it is trouble. Direct the flow away from directly below the house and you are good to go. If there is any water body like a stream, pond or anything like that, steer the flow toward it.
- Water when dry
The same way too much water is not good, too much dryness is even worse. If you have a green cover, and you seriously should, make sure it is well watered. Even simple sod will keep the soil perfectly moist and just the way it has to be. Water your lawns and make sure you do this sufficiently in the summer months.
- Moisture levels
Another often overlooked point is that the soil directly adjacent to the actual foundation and the soil holding up the foundation have to be on the same level of moisture. If not, water will flow from wet to dry. While it may not be possible to be overly accurate about it, getting it more or less right is sufficient.
Trees are good, shrubs and bushes bring life to the landscape, but some types of vegetation have root systems that quickly deplete upper soil moisture; be wary of them.
