Geomembrane Plastic Lake Liners

All soils leak, some types more than others.  Keeping a body of water full provides better water quality, greater fishing and a more scenic view.

Water features add value- Water features play many roles in today’s world. The beauty and habitat of a well-placed pond or fishing lake can improve the appearance of even the flattest, most mundane piece of land — and make the surroundings a better environment in the process.

We have completed many lake construction projects over the years that were conventional and they hold water according to our design expectations.  Sometimes, however, Mother Nature does not provide you with the most ideal materials to build a beautiful fishing or recreation lake on your property in that just perfect location.   When the soil is not perfect and the soil tests come back iffy or altogether unsuitable,  a geomembrane plastic lake liner is usually the only solution.

Soilmovers LLC geomembrane lake liner construction projects are most often in two categories:

Renovating a leaking lake-  We are called in after the land owner usually tries several unsuccessful remedies to fix his leaking lake at great cost.   “Fixes”  may involve draining the lake and plating the bottom with heavy clay or dumpling bentonite clay directly into the lake where the leak is suspected.  In most cases, the lake building catastrophe could have been averted by proper soil testing prior to any lake construction.  Certain types of soils will simply not hold water. Typically, we see 7 out of 10 clay or bentonite liners fail. Plating with heavy clay has a better chance of success but it may prove to be more expensive than the original lake construction costs.

On a few occasions we have just seen gross lake construction errors where the dam was improperly constructed.  This engineering failure is not repairable most of the time and must be demolished and started over.  It is always cheaper to do it right the first time!

New construction in a less than ideal site-   Sometimes the land owner has the ideal spot for a great trophy fishing lake or recreation lake.  It is scenic, fits well with existing terrain, has adequate watershed to fill the lake and is in a location convenient to recreational use and fishing.  BUT –  the soil tests we perform indicate the location is less than ideal for holding water.  At this point, the landowner needs to question an unscrupulous contractor that was consulted before our arrival.  Many contractors want the job so badly they will tell the land owner anything in order to get the job.  Lining the lake bed with on site heavy clay or using a bentonite clay liner are typical schemes we run across.  The other contractors will say things like “it should hold water” or they  “dug another lake just up the road last year in the same type soil and it is holding water fine.”   Hard facts are most local excavation contractors do not have the experience to install a plastic lake liner correctly.  The salient fact to remember is once that contractor’s equipment is loaded up and gone from your property, you are on your own.

The only guaranteed solution is a geomembrane plastic lake liner.

Geomembrane plastic liner used in tandem with solid design turns a less than ideal piece of land into a valuable asset. In addition, geomembrane liner use prevents seepage loss thereby conserving millions of gallon of water annually.

Experience counts- We believe as with any construction project, the end result is only as good as the project specifications, materials, and quality of installation. Soilmovers LLC has a long history of successful lake liner installations and the references to verify our claims.

Project Specifications- The plastic lining you choose is dependent upon many site unique factors. It’s why we don’t have any “canned solutions”  to offer you.  Many times we can save you both time and money in your lake lining choice based upon our hands on past experience with past assorted lake liner projects.        .



Types of Geomembrane  Plastic Lake Liners

PVC Geomembranes – (Poly Vinyl Chloride)

Description —
Poly Vinyl Chloride (PVC) is the most commonly specified lining material in the industry. Manufactured by the calendaring or extrusion process, it is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane liner with many uses and advantages for the user.

PVC has high puncture strength and excellent abrasion resistance. It is resistant to a number of industrial chemicals.

Because of its high flexibility, PVC liners readily conform to subgrade contours and offer excellent interface friction without being textured.

The use of a PVC geomembrane liner prevents contaminants from entering groundwater sources or streams. In addition, it conserves potable water resources by preventing seepage loss.

PVC is available in a variety of formulations including fish grade and oil resistant. It is available in 20 mil, 30 mil, 40 mil and 60 mil thicknesses.

Fabrication —
PVC lake liner material is delivered in rolls of 6-8′ wide material and fabricated into large panels for delivery to the project site. PVC can be fabricated into panels of up to 25,000 sf and shipped to a site for installation. The use of large fabricated panels allows field installation crews to install acres of lining per day while limiting the number of field seams.

HDPE – (High Density Polyethylene)

Description —
HDPE is the most widely used geomembrane in the world and is used more commonly internationally due to its availability and relatively inexpensive material cost.

HDPE is an excellent product for large applications that require UV and Ozone resistance, chemical resistance or high-quality installations. Typically used in landfill and mining applications, this product is delivered in large rolls with a width of 22.5′ and is heat welded in the field by trained technicians providing a high quality, test certified installation. HDPE offers the most cost effective liner for large projects. HDPE is available in thicknesses ranging from 40 to 120 mil.

HDPE Lining materials are a cost-effective choice for exposed lining projects. This product has been used in landfills, WWT lagoons, animal waste lagoons and mining applications.

Over the last 7 years, almost 50% of our lake construction projects have involved the installation of a plastic lake liner.  Obviously, 50% of all new fishing and recreation lake construction does not involve a plastic liner.   A plastic lake liner construction project is more costly and requires a higher level of expertise than many excavation contractors possess.  We get hired for the higher end projects and our percentage of lake liner projects reflects this.
