Sometimes they would connect the line directly into the drainage for the fields as well. While this worked wonderfully for many farmers, it did need to be improved over time to get us where we are today. As the technique started spreading, some people found themselves in areas that could not drain to lower spots, because they were IN the lower spots. Unfortunate for them, but not beyond human ingenuity.
As these situations became more common, someone along the line decided to dig a catch basin for the water to gather. They then brough in a water pump from outside and pumped the water gathered in the basin outside.
Installing weeping tile can be back-breaking work so engaging a professional is definitely recommended. In addition to having the proper equipment, a waterproofing company can determine the proper slope, materials needed plus offer a warranty if any problems arise later on. The information listed here will give you a better understanding of the process and help you plan for any preliminary work requirements:. A inch wide trench must be dug around the outside perimeter of your home. It should slope one inch for every eight feet and extend down to the footings.
Talk to your contractor about how to dispose of excess soil. Two or three inches of washed gravel should line the bottom of the trench. This natural filter will allow water to drain without clogging from organic material. Rigid PVC pipe with pre-drilled holes is the most popular for its durability and easy maintenance. Covering the stone or wrapping the pipe with landscape fabric will keep it root- and obstruction-free. Leaving a clean-out joint that remains above ground will help in future maintenance.
Covering the pipe and filling the trench with gravel or a combination of sand and gravel will allow easy access. Adding gravel, then dirt with sod will conceal the weeping tile completely and provide a base for landscaping.
Using a circular saw with concrete blade and chipping hammer, the basement floor is cut out. The opening should be approximately 12 inches wide and run around the entire foundation. Remove all concrete slabs sections to access the gravel below. Then dig a trench one to two feet deep where the concrete has been removed. Stop digging when you get to the footer. Similar to an exterior installation, a fabric-covered PVC pipe should be used with holes or slits to allow for drainage but resist clogging.
Place the slits upward, install sufficient weeping tile to cover the entire perimeter and end it at your sump pump. Once the tile has been connected to the sump pit, cover the entire trench area with gravel. Let it settle for a day, pour the concrete and smooth it with a trowel.
As you can see, both exterior and interior weeping tile installations are labor-intensive. Unfortunately, that also means it can be costly. This is especially true when it comes to the structures that we build and the management of land.
One of the most common ways to protect a property against water damage is the use of a French drain. Also known as a weeping tile, sub-surface drain and a whole host of other names, this style of drainage system can be used in a variety of different situations. In this post, we are going to take a closer look at French drains, the type of drain service they receive, how they work and the reasons that some properties might need them.
French drain being installed at a home in Toronto. As you may have guessed, a French drain is a type of drainage system. The primary purpose for most French drains is to manage surface water and groundwater. With most French drains, the idea is to take water that could threaten a structure, and move it to a place where it is no longer a threat.
You may have seen a French drain before. It looks like a trench that has been filled with gravel. Under that gravel, there is likely to be perforated drainage line, and if you were to go to the discharge end of the French drain, you would see the end of the perforated pipe.
While this is usually acceptable, there are some slight differences between the two. A French drain is typically installed just below the surface, and its main intent is to prevent the over-saturation of soil. A weeping tile is a type of French drain, and it is a drain that is built to protect a structure against hydrostatic pressure.
Since they are often used to protect the foundation of a structure, the pipe is usually much deeper in the ground. If you are using the terms interchangeably or hear someone else do, it is no big deal. It has generally become accepted that they both refer to the same type of drainage system, and people will know what you are talking about either way. Whether you are talking about a French drain or a weeping tile system , the drain will work under the same principles. Gravity will always cause water to flow downhill, and the flow of water is always going to follow the path of least resistance.
The operation of a French drain relies on these facts of nature to manage the moisture in soil. As I mentioned before, a French drain is made from a piece of perforated pipe that is laid in a trench and surrounded by gravel. The gravel or stone in a French drain serves multiple purposes, but the most important feature of this packed gravel is that it is more permeable than the soil on the surrounding land. In technical terms, the gravel or stone in the drain would be known as the envelope.
The increased permeability of the envelope allows water to flow more easily, and this draws the moisture from the surrounding soil, making the trench the path of least resistance.
A French drain is buried underground, collecting ground water. French drains have been around for quite some time, but a modern French drain is also likely to have some type of landscaping fabric covering the gravel. The purpose of this fabric is to prevent the growth of weeds and to reduce the amount of sediment that can run down into the trench, and potentially clog the French drain.
These systems only have one purpose: removing excess water. The water leaches through the soil into the pipe, where it drains into a non-porous pipe that usually connects to a sump pump. The sump pump then sends the water out away from your basement.
