If water finds its way into your basement it can cause devastating damage, and can render the room useless. One of the easiest problems to solve, but also a really common point of entry for leaky basements, are tie rod leaks, which are small holes in your foundations that can let water in.
Direct Waterpoofing can help you to solve any and all basement and foundation damp problems, with our full range of professional solutions.
Tie rods are small steel rods that are are used to hold together forms during the construction of your home, ready for concrete to be poured. When the concrete is poured the rods are removed, and this leaves vulnerable points of access that can eventually cause water to find its way into your home.
Most homes use tie rods during construction, but some more modern homes use snap ties, which do not result in the same problem. If your home has holes in the foundations as a result of tie rods, it is always a good idea to have them fixed, especially if water damage starts to show.
If your tie rod holes are leaking, then you might see a small stain about the size of a coin on the inside of your basement walls, or a water line that leaks all the way down to the floor. If the leak is severe, water can even pool or flood your basement.
There are usually between 5 and 8 tie rods on a wall, and it will be walls that are exterior that will be your concern. You may therefore see water damage appearing in regimented lines, where the tie rods once were.
During the original construction of a lot of homes, small metal rods, called tie rods, are inserted into the concrete form in order to hold the inner and outer forms together, and provide the structure with which the concrete can be poured. They are placed around 18 inches apart from one another, sometimes in two rows.
After construction, they are usually either removed entirely, leaving a hole. The builders may make some attempt to fix the tie rod holes, at least aesthetically, by covering them with hydraulic cement and a coating, but over time this can wear off, revealing a very vulnerable point for water to enter.
Water takes the path of least resistance, and so will always flow through the tie rod holes if possible, given that they are essentially hollow all the way through. This is why the problem is so common. If water finds its way in, then it will also end up in your basement!
Direct Waterproofing have a number of solutions available in the case of tie rod hole leaks, and we can deal with one leaking tie hole, or a whole wall of them. The job is usually relatively straightforward and cost effective, and involves the tactful application of a high grade sealant injection, or a swell plug, in order to fill and bond the hole.
If there are wider issues at hand, then we can also examine how to provide permanent interior or exterior waterproofing solutions that can make sure water never finds its way into your basement again.
Tie rod holes are usually created while building a foundation wall. Smooth steel rods are placed within the concrete foundation. The rods hold concrete forms together to prevent bulging due to the weight of wet concrete. The tie rods pass through the concrete forms. With the rods in place, the concrete forms do not expand outward even under the intense pressure of the wet concrete that fills the forms to create foundation walls. When the wet concrete is poured, it flows over and around the tie rods. When the concrete set hardens, the builders remove the tie rods, leaving tiny holes known as tie rod holes.
After removing the tie rods, contractors typically patch the tie rod holes with hydraulic cement or other suitable material. However, freeze and thaw cycles and ground movement might cause the patching work to wear out over time. This might pose an issue in foundation walls when groundwater makes its way through the holes into the basement. The tie rod holes do not affect the overall strength and stability of your building. However, they might cause leaks in the basement and foundations.
Tie rod holes are common, especially in older homes. You should respond fast if you notice water stains or tiny holes where water is dripping or seeping through. Another common sign is a water line that leaks to the floor. In severe cases, the water may pool in the basement or even cause flooding. You should seek professional tie rod hole repair. You should only have a professional and reputable waterproofing contractor repair the holes to prevent the problem from recurring.
