Aquascreen, aquatic weed / benthic barrier


Aquascreen is an aquatic weed barrier, also called benthic barrier, that covers the sediment that can sometimes be found in shallow lakes areas, along shorelines and beaches or in older lakes and ponds.

Technical specifications

Aquascreen is a bottom screen that compresses aquatic weeds while reducing the light needed for their growth. Aquascreen is an environmentally friendly barrier solution made of an ingenious poly mesh fabric designed to control aquatic plant growth at the shoreline, in new or existing ponds or lakes.

Many cottage owners suffer the nuisance of shoreline aquatic weeds which is becoming more problematic as nutrient rich lake sediment accumulates and water quality changes. We recommend you cut down the aquatic weeds first before installing the Aquascreen for best results. Some clients have experienced minor, temporary lifting after initial installation due to gaseous release; simply readjust the rocks or weights.

Controlling aquatic weeds and plants with Aquascreen

Controlling these unwanted plants and weeds with a barrier method is not a new technique. Instead of digging weeds and plants out of the pond bottom it made sense to pond owners to bury them under barriers of home made screens or “carpets”. Previous methods included binding large pieces of canvas or even standard window screen together and sinking them with large metal frames or bundles of bricks but these methods were prone to failure and not an efficient use of time or money.

Aquascreen can be cut with sharp scissors and sewn together to form larger screen sizes or special forms to fit snugly around docks or swimming areas.

It can be anchored into position on the pond or lake bottom with patio stones or rocks or even rebar inserted in PVC piping but the preferred method is by staking the Aquascreen with 10″ or 12″ steel pins through the 1/2″ plastic grommets that are provided with the roll.

Many common aquatic weeds can drastically reduce the beauty and health of an aquatic ecosystem. Cattails are notorious for coming back after having been manually removed and due to their root structure tend to come back thicker and stronger as you try and remove them. Pondweed, milfoil, Canada water weed (elodea) and wild celery (American eel-grass) are a few of the other species that can overtake a pond and reduce the enjoyment of the pond.

Aquascreen will eliminate the annoyances of thick mud and aquatic plants underfoot thus enhancing the experience for bathers on public and private beaches or resort areas. Only strategic areas of beaches or shorelines need be treated with the Aquascreen and this small expense can dramatically improve the quality of the shore where bathers enter the water. It also keeps golf course ponds and water-hazards looking clean and clear and will provide rapid aesthetic results near docks and marinas, riverbanks and waste water ditches.

Aquascreen is not a miracle product and should only be considered as a site specific aquatic weeds management tool. It should not be considered as a permanent installation although it can and will withstand winter under water. In this case, spring inspection of the benthic semi-barrier will be necessary to replace it and reassure its anchorage. Also, gas from decomposition can stay trapped under Aquascreen if installed in a nutrient rich aquatic environment. Algae could grow on its surface and in the apertures preventing gas to escape and therefore lifting of the material can occur. The owner must assure sediment and algae free surface, by sweeping or washing for example, and are the only one that can be held responsible for its maintenance. Ltd. guarantees the quality of the Aquascreen but is not responsible for the installation and cannot be kept responsible for elements on which it does not have any control.
