Eliminate sand washouts and permanently protect your bunkers from subsoil contamination.
Request a Consultation arrow_forwardBunker liners are highly durable, permeable mats engineered to create a permanent barrier between the bunker sand and the native subsoil. By preventing stone contamination and virtually eliminating sand washouts during heavy rainfall, they drastically reduce maintenance costs while ensuring consistent, championship-level playing conditions year-round.
From our proprietary GolfDren system to a wide range of alternative technologies, we deliver the exact solution your course demands.
GolfDren Solution
Leveraging our extensive experience in testing various geotextiles, we engineered the GolfDren bunker liner. Our products feature a premium structure composed of high-quality polypropylene fibers.
Additional Liner Options
A solid base layer of engineered aggregate or porous concrete designed for rapid, high-volume water drainage.
Heavy-duty surfaces woven from highly durable polymer fibers, serving as a mechanically robust foundational layer.
A sod-based organic barrier that provides simple, cost-effective protection against sand contamination in less demanding environments.
A flexible base combining high physical durability with excellent drainage and superior contour adaptability.
GolfDren liners are available in two specialized variants. Both deliver the same mechanical performance, allowing us to recommend the perfect match for your bunker's unique subsoil conditions.

Our liners are easily installed using standard tools and securely joined using a high-strength adhesive, creating a continuous, highly durable protective layer.
Streamlined installation, significant labor savings, simple repairability, and low logistical costs guarantee a fast and measurable ROI.
Designed with playability in mind. If accidentally struck by a golf club, our forgiving liner material ensures absolutely no damage to the golfer or their equipment.
Polypropylene fibers form a highly durable, non-degradable matrix built to withstand the harshest natural environments.
Engineered to resist severe temperature fluctuations. The liner remains dimensionally and functionally stable through freezing winters and scorching summers.
Chemically inert and environmentally neutral. Our liners will never degrade, oxidize, or leach harmful substances into your soil or groundwater.
The bunker subgrade is carefully shaped, compacted, and cleared of debris to create an optimal foundation for the liner.
The liner is unrolled and precision-cut to match the exact contours and dimensions of the bunker, ensuring complete wall-to-wall coverage.
Individual liner segments are joined using a specialized, heavy-duty adhesive, binding the material into one continuous, extremely durable protective layer.
Finally, the fully bonded liner is firmly anchored to the subsoil using securing staples, locking the entire system permanently in place.
