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 Outdated practices or myths about dewatering should be addressed and eliminated to save your project time and money!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 In fact, many construction dewatering myths are no longer valid.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 This no longer holds true, because earthen dams are outdated and likely to fail or be unsafe.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.

Your Guide to Boat Ramp Renovation

Your Guide to Boat Ramp Renovation

Nothing lasts forever and that includes boat ramps, too. Through years of use, a boat ramp can deteriorate or break apart and become dangerous, making it unsafe to use. When the structure of your boat ramp is compromised, it's time for a renovation. Click To Tweet

Renovating a Boat Ramp

Whether the boat ramp is for private or public boating access, it is imperative there is a safe ramp that can handle different types and sizes of boats. During the renovation process, it is important to make sure to take certain guidelines into consideration. Here is a quick guide to help you on your next boat ramp renovation.

Boat Ramp Site Considerations

Before you begin your renovation process, you need to take into consideration what the ramp is being used for, site accessibility, the water depth, and siltation rates. Make sure to analyze the impact of aquatic plants, as well as the fish and wildlife. Make sure you have correct permits in place before you begin as well.

Construction Specifications

A proper site plan needs to coordinated so you don’t run into issues of the boat landing being too small, not enough turning radius, or the parking area being too small. Once you have your site plan, it is important to create a ramp design. The size of your ramp is an important factor and needs to accommodate boats and trailers of all sizes. Make sure to figure the slope and width, and take into consideration the area around the ramp, too. Ramps around rivers or angled may have silt issues if stabilized ditches are not placed along the sides of the ramp to catch runoff after heavy rains.

Dewatering Process

To accurately perform a boat ramp renovation, dewatering the area is a top priority. There are a few dewatering methods, but an inflatable dam is a safe and environmentally friendly method that is safe and cost-effective. Cofferdams come in a variety of sizes and can work in water up to six feet deep. An Aqua Barrier® Inflatable Water Dam works well in rocky surfaces and gives you the edge on competitors.

Ramp Construction

Once you have dewatered the area of renovation, it is time to remove the old boat ramp and begin your new ramp construction. There are multiple ways to construct a concrete boat ramp, so decide which method will work best for your project. Make sure to choose good quality materials and construction methods, following specifications on the site plan.

Boat Ramp Renovation

The design of your site, the boat ramp plan, and the materials and tools you use will all impact your construction and maintenance costs. By careful planning and using environmentally friendly tools, like the inflatable water dam, your boat renovation project will be completed without any issues.
