What is Sandbag Cofferdam | Sandbag Cofferdam Advantages

A cofferdam is a temporary building that aids in keeping construction sites somewhat dry while work is being done. What exactly is a sandbag? Simply put, a sandbag is a bag that has been packed with sand and clay. Sandbag cofferdams are created by using these sandbags in this manner.

Empty bags or empty cement bags are initially collected as needed in this arrangement. After that, a clay and sand combination is used to partially fill them. The remaining free space between the bags is then filled with liquid to seal them, after which the partially filled bags are put down in courses much like masonry work.

It has been found that sandbag cofferdams may successfully withstand fast water currents. The cofferdam’s side slope is so steep that sandbags can even support the vertical face.

Advantages of Sandbag Cofferdam

Here, the pros of sandbag cofferdam are as follows.

• To benefit dynamic pile function.
• To locate row and float base.
• Install base of piers and support of the platform, bolt, etc.
• To surround a place for the separation of lake or ocean.
• To offer an operation foundation for the construction base while water will face it.
• To offer a place for conducting the base activity except harming.

Common Problem Using Sandbags for Dewatering

• Sandbag construction takes a lot of time.
• More labour was needed for the sandbagging.
• It will be difficult to incline sandbags.
• Sandbags produce more dirt.
• Sandbags are bad when they are more durable.
• Flooding will have the shoddy outcome of sandbags.

Cofferdams VS Sandbags

You might be wondering why cofferdams are better than the tried-and-true sandbags usually utilised in these situations if floods are on the horizon.

Although the sandbag has repeatedly demonstrated its ability to perform the task, it is only performing minimally in comparison to advancements that have been made over time. The temporary water-filled cofferdam is a great improvement over the more traditional techniques, like using sandbags, for a variety of reasons.

Let’s examine the differences between sandbags and our cofferdam so that you may understand why our cofferdams are the best option.

Sandbag: requires the import of dry soil (sand) in order to fill the bags in the pouches.

Cofferdam: fills the interior compartments with local water.

Sandbags: disposal needs a Hazmat crew’s aid for health and safety reasons.

Cofferdam: easily by emptying the inner bladder and storing them, making them reusable.

Sandbags: are heavy, even before use.

Cofferdam: are made to be portable and light in weight.

Sandbags: are vulnerable to on-site water seepage.

Cofferdam: once the location has been prepared, provide a watertight seal.

Sandbags: It poses a severe safety risk since it can absorb bacteria and garbage from the water.

Cofferdam: does not absorb the dirt in the water; instead, it repels it by sealing it out.

Sandbags: require much more labor to install.

Cofferdam: requires very little work to set up and take down.

Sandbags: can occasionally need to be changed out in the middle of the job because they can completely cease operating due to over-filling.

Cofferdam: do not need any additional care during setup or breakdown.

Sandbags: can be pierced by on-site debris.

Cofferdam: are made from geotextile materials that are resistant to punctures.

Sandbags: require a substantial amount of funding for labourers, site cleanup, Hazmat expenses, disposal, as well as supplies and transportation for supplies.

Cofferdam: are affordable since they need little labour, don’t require disposal, and can be reused.

Sandbags: are for purchase only.

Cofferdam: can be hired through our business.

We hope the information above has helped you understand why our temporary, portable, reusable cofferdams are superior than the typical sandbags that can also be used during construction or times of floods. By being informed, you can choose the option that is best for your project or emergency needs.
