Why should I use a liner?
Sand Guard Bunker Liner Systems
Today, bunker liner materials are comprised of different materials, depending upon the manufacturer. Various construction materials are available on the market for bunker liner, including pour-in-place permeable rubber liner, porous asphalt, porous concrete, erosion control fabric/cloth, non-woven matting, field turf, sod, polymer-based liquid (spray on material applied to gravel or the subfloor), rubberized mats and batch mixed.
Reasons to use:
•
No waiting for materials to show up
•
Easy and fast installation
•
Flexible AND durable
•
Eliminates washouts
•
Reduces maintenance

What preparation is required for the bunker floors prior to installing Sand Guard™?
The bunker floors should be prepped ahead of time in the following manner: The edge or sand line area of the bunker features should be delineated by the owner/golf architect; floors should be excavated, cored out, and drainage installed with substrate soils and drainage trenches compacted with a plate compactor.
During the day of the Sand Guard™ installation, a small, hand-dug anchor trench should be cut into the floor edge with a flat tipped shovel to assist with bonding the liner to the perimeter of the bunker sand line area during the curing process. We generally recommend a minimum of 3- to 4-inches of bunker sand along the edges and 5- to 7-inches plus of compacted bunker sand within the base of the floors.

How long does Sand Guard take to cure?
Sand Guard will generally take about 24 hours to fully cure. Since it is a moisture-cured formulation, careful attention to ambient air humidity, wind, and moisture levels during the installation is critical. Installations should NOT take place when rain is in the forecast. The material sets up quicker during high humidity than low humidity, so adding moisture with a garden-type pump sprayer and an irrigation syringe hose with a fine spray nozzle (see the Sand Guard Installation Tools Sheet) during lower humidity is especially important and recommended in most applications.
What is the temperature needed to install Sand Guard?
Sustained air and surface soil temperatures of 45° Fahrenheit and above are needed to install Sand Guard properly.
What does the training to install Sand Guard involve and how long does it take?
Sand Guard training involves on-site education of the installer’s crew members by one of our Sand Guard/Porous Pave staff members. You will be working alongside crew members in an actual installation and it typically lasts for 1 to 2 days. Training includes instructions on how to store and transport the material; set up the work area; coat equipment and mixer with vegetable oil; mixing rubber, rock, and binder together in a mason’s mixer (plaster or mortar mixer); empty the Sand Guard material from the mixer into a wheelbarrow; pour mix into place; rolling; finishing and misting with water to assist in curing.
What is the crew size needed to perform installation & how many square feet can they install in one hour?
A good crew size is 5 to 6 trained personnel. Once trained and “in the groove,” the crew can install 500 to 700 square feet per hour or 5,000 to 6,500 square feet per day. Increased daily production rates can be achieved with larger mixers or additional mixing crews.
"We selected to use Sand Guard liners for our Fazio designed bunker renovation project. We recently experienced an extreme 6.4 inches of rain overnight, and Sand Guard performed as advertised. Little to no maintenance was required after the storm, night and day compared to our existing bunkers.
We considered several liner options during the project planning process, and after this rain event, I'm sure glad that we selected Sand Guard to help protect the Club’s new investment from the challenges of severe weather."
