Although there are a lot of different ways that you can try out for environmental remediation, it is important to check them out. In line with this, cutoff walls to generate groundwater protection are definitely valid. You see, these walls are the ones that will be able to help out in restricting the movement of the groundwater so that it would not exit the location. It also helps out in cases where the groundwater is contaminated or when it is penetrating any contaminated area as well and you are in need of clean groundwater. You see, in line with this, it would be great to know more about the different kinds of cutoff walls that are often seen in site remediation type of projects as well. They are consisted of slurry walls, cement walls as well as sheet piling. It would be good to know them and have an idea about what they are so that you will be able to properly check things out as well.

Slurry walls

This is a technique that is used to build a reinforced concrete type of walls in areas where there is soft earth that is quite close to say, open water or with any high groundwater type of table. It is great because it is a technique that is normally used to build a diaphragm which is walls that surround tunnels as well as open cuts and normally used for foundations as well. This is something that you might want to consider as well if you ever plan on making sure to keep things in tact and it is a good option for remediation as well so it is really something that you should take a deeper look at.

Cement walls

This, on the other hand is something that is quite comparable to slurry walls but they have cement based type of slurry instead of the clay type one that has low permeability one. The construction of this can be through trench and fill just like the construction of a slurry wall. It can be utilized through substantial excavation that forms the built that for concrete walls as well. Through this, the excavated area around the wall is going to be backfilled too. The backfill can have high permeability materials in that is employed to be able to capture and to channel the flow of groundwater as well as recovery through contamination as well as to prevent being contaminated as well. Its costs tend to be higher than the slurry walls but it is because mainly if the wall is formed in its place. The higher the cost is, the higher is the performance going to be as well, so it is something to consider at the same time too.

Sheet piling

This is known to be a tech that gets used frequently to install the cutoff wall. It is normally used to be able to channel underground water into what is known as a treatment cell. A treatment cell is a space where the water is going to be subjected to treatment and to which is going to be used as a short-term cutoff wall that can happen during the remediation stage too. It is great but the cost of it is quite high so it is not really the normal options when it comes to it. However, the range of utilizing this one is really better especially when it comes to sealing the joints that happens in between all of those sheets at the same time too. The efficiency of this is also quite high as well so it really is something to keep your eyes on at the same time.
