Better drainage for bunker liners. No more clogging with debris.
Request a consultation arrow_forwardSeparation solutions (bunker liners) create a layer between the sand and the substrate, preventing contamination with debris, improving drainage, and reducing the formation of potholes after rain. This keeps bunkers looking great all year round and minimizes maintenance.
We offer our own technology as well as a range of other custom solutions. We will recommend the best one for you.
Patented GolfDren solution
With years of experience, we have developed a durable geotextile separation mat that combines the best properties.
We also offer
The bottom of the bunker consists of a solid layer of aggregate or porous concrete that quickly drains water.
Areas made of durable artificial turf or polymer fibers serve as mechanically stable bases.
A layer of natural sod creates a simple barrier against sand contamination, ideal for less exposed solutions.
A flexible mat made from recycled rubber that combines high durability with drainage function and good moldability.
We offer two types of liners based on the substrate. Both types provide the same effectiveness.

Thanks to our experience, we designed a material that combines the best properties of other technologies.
After installing the solution, there are no additional maintenance costs, and the return on investment is very quick.
We have full control over both production and delivery. We always deliver the material on time and with guaranteed quality.
The material stays stable from –30 °C to +30 °C, resists UV and field loads, and its soft surface prevents damage from club impacts.
Polyethylene fibers are fully recyclable and do not burden nature – even after years of use.
We usually supply materials in white. However, upon request, we can also produce them in black or sand.
First, we prepare the entire bunker. We clean the base of stones and soil, carefully level it, and create a solid foundation for the mats.
Then we unpack the rolls and cut them precisely to the shape of the bunker. Each piece is laid so that the mats adhere to the surface without gaps.
Once all parts are in place, we weld them together. This creates a continuous surface that ensures no impurities can penetrate.
Finally, we anchor the entire mat with special pegs. This keeps it firmly in place, and the bunker is ready for sand filling and immediate use.
