Top 4 Dewatering Myths Debunked

Top 4 Dewatering Myths Debunked

Dewatering for a construction project might have been arduous and time-consuming in the past, but a lot has changed over the years making these projects easier and safer than ever. In fact, many old dewatering practices have been abandoned, meaning that sticking with them can end up costing you time and money. Outdated practices or myths about dewatering should be addressed and eliminated to save your project time and money! Click To Tweet

Debunking Dewatering Myths

With new technology, dewatering is simpler and more cost-effective than in previous years. In fact, many construction dewatering myths are no longer valid. Here are three dewatering myths that have been debunked with the evolution of the cofferdam.

1) Earthen Dams Are Best

Earthen dams have been used for thousands of years and were once thought to be the best option for a dewatering project. This no longer holds true, because earthen dams are outdated and likely to fail or be unsafe. Earthen dams are made of dirt, making their structure weak. This can cause the dirt dam to fail when sloughing or erosion occurs. An inflatable cofferdam lets you work with more stability and control and take minimal manpower to install.

2) Drain the Entire Pool

The myth that to repair a pool you must drain the entire thing is incorrect if you have an Aqua Barrier® inflatable dam. Inflatable water dams allow you to dewater a section of the pool for repairs, rather than draining the entire pool. The inflatable water dam is actually filled with pool water, and will conform to your pool’s shape, forming a seal. When the work is complete, the water is drained back into the pool, conserving water.

3) Sandbags Are Ideal

Sandbags have their place in construction but in most cases, the Aqua Barrier® Cofferdam will get you better results with far less prep time. To achieve a 100 foot long x 8 foot high sandbag wall requires more than 50,000 sandbags, adding time and effort from your employees. Sandbags also require special disposal, resulting in extra cost. An inflatable water dam requires no heavy lifting and equipment, and it is reusable and eco-friendly.

4) Inflatable Dams are Expensive

Think an inflatable cofferdam will be too expensive? Try the Cofferdam Cost Evaluator. This great tool allows you to get your costs before making your purchase. It also allows you to compare the inflatable cofferdam price to that of sheet piling or earthen dams. You will soon see that the inflatable dam wins out in the end, not only with ease of function, cost-effectiveness, but it is reusable and therefore, environmentally safe.

Dewatering Myths Debunked by the Aqua-Barrier Cofferdam

With the Aqua-Barrier cofferdam, dewatering projects have never been easier or more cost-effective. With inflatable cofferdams, you will cut down on post-work clean-up, reduce workers comp claims for heavy lifting, and also reduce installation and removal time, too.

7 Top Tips to Prevent Erosion on Construction Projects

7 Top Tips to Prevent Erosion on Construction Projects

Erosion is one of the top issues facing the construction industry today. The Department of Agriculture estimates one billion tons of topsoil are lost each year due to erosion. This issue not only causes topsoil to be displaced, but it also is the culprit for clogging waterways and damaging adjacent properties.

Preventing Erosion

Erosion can be caused by many variables and each situation will most likely have a different solution. Here are seven ways to help prevent erosion on your next construction project.

1) Observe the Site

When starting a new project, it is imperative to observe the site’s slopes for any potential problems. Also, take a look at any adjacent sites to see how your project will affect that area, as well. It is ideal if you can observe the site while it is raining in order to plan accordingly.

2) Divert or Slow the Water

Water and wind are the main offenders when it comes to erosion. Before beginning construction, come up with a plan to divert or slow the movement of water. Controlling runoff waters effectively will reduce erosions and sediment issues on your construction site.

3) Don’t Disturb

Disturb the area as little as possible. Only excavate a small section at a time to reduce the risk of remediation. Even though it may take a little more time, the potential costs of erosion could end up costing you more in the long run.

4) Ground Covers

As soon as excavation is complete, it is essential to create a ground cover to help minimize erosion. The faster you can get your ground cover growing, the less erosion is possible. Check with the landscaper to see about any specified seed species to use. If seeding is not an option, plastic sheeting is helpful in shielding the soil from rain and wind. Plastic sheeting is only effective in small areas, however, and can do more damage if used in large areas.

5) Mobile Grinders & Chippers

If you are removing trees from the construction site, bring a mobile grinder or chipper to make mulch. This ground-up material works wonders as an erosion aide. This material can also be used for temporary roads and ground cover. You can use this mulch for slope stabilization or save it to blend with the soil for landscaping towards the end of the project.

6) Sediment Control

Sediment is the soil which is dislodged by water flow. Once the sediment is in fluid motion, it becomes difficult to collect and further exasperates erosion. Silt fencing, filter socks, and straw wattles are all commonly used to catch and control sediment. These control methods are not designed to handle high water pressure, so do not install them across waterways, ditches, or other areas of concentrated water flow.

7) Inflatable Dams

More and more contractors are turning to inflatable water dams for dewatering needs and erosion control. They are cost effective and cheaper than traditional methods of sandbags and earthen dams. They are easy to install in both moving and still water and conforms to the boundary of any site, providing a seal that prevents the passage of water on your worksite.

Erosion Control

Erosion control on construction sites takes thought and planning. Click To Tweet In fact, federal regulations and other applicable laws require you to have an erosion control plan to prevent soil and water from affecting other areas and bodies of water.

3 Construction Projects That Require Fast Dewatering Solutions

3 Construction Projects That Require Fast Dewatering Solutions

When preparing for a construction project, the idea of dewatering can be daunting. This is especially true if you’re on a strict deadline. Much of this dread is born from outdated dewatering methods, which proved costly and arduous. 

Unique Requirements

Construction sites that lie underwater pose unique challenges and requirements. Not as cut and dry and most projects, the need for dewatering makes underwater construction especially unusual. This means that when approaching such project it’s always a good idea to assess safety regulations, timeline expectations, and dewatering options.

1) Dam Repair

The safety and viability of dams are a major priority for city and state engineers. Dams store water in case of fluctuations in demand, but they also impede floodwaters from rising. This stored water is then either released to the river below the dam or diverted for other uses. Vulnerabilities in a dam should be immediately repaired to avoid catastrophic damage. In order to get to the damaged material, temporary dewatering is necessary.

2) Boat Ramp Construction

A boat ramp is usually constructed of a concrete ramp poured over a steel frame. They provide an easy and safe way for vehicles to back boats into the water. Most boat ramps go well under the water line to account for low tides. To build a boat ramp,  the area must be dewatered for digging and construction.  Once completed, the water is released and the boat ramp can provide access to the water.

3) Pipelines

Oil and gas pipelines require regular inspections. Make them quicker and easier with an Aqua-Barrier® Cofferdam. These are capable of controlling surface water up to 6 ft. deep and can be used in a variety of environments. During these inspections, pipelines that show damage or corrosion are flagged for repair. Such damage is an extreme concern for oil and gas operators. Repairs must be made safely but speedily, to avoid the risk of contamination or danger. With the right dewatering solution, inspections and repairs are manageable and safe. 

Know Your Options

In the past, dewatering was a long and arduous process that usually involved sandbags, heavy earth or stones piled high to keep the water at bay. Not only was the process time-consuming, but posed some serious safety concerns. With new technology, dewatering is easier and safe than ever.  Embracing new, eco-friendly solutions like the Aqua-Barrier® Cofferdam can save you and your crew time and money.  

Safe Dewatering for a Successful Project

The success of your project is based on how safe the process was, how quickly it was completed and how efficiently your materials were used. With smart dewatering, such as that with an inflatable bladder dam, much of the chance and guesswork is eliminated. Click To Tweet
