When there’s extreme weather – from storms to droughts – your bunkers really show it. The key to better performing bunkers is moisture control. As soon as the sand on steep bunker faces starts to dry out, the risk of plugged ball lies and washouts increase significantly. Our bunker liner system gives you total drainage control and keeps bunker moisture at optimal levels to eliminate washed out bunkers, soil contamination, plugged ball lies and other bunker maintenance and playability problems.

Capillary Bunkers not only rapidly drains rain from storms, it moves moisture back up to the bunker sand during drier weather through special micropores and capillary action. The patented Capillary Bunkers system stores and restores moisture to the sand faces to provide more ideal playing conditions. In addition, we are the only product on the market that has a 1000 psi rating in ASTM testing protocols, and can withstand severe climates and frozen ground. No other product comes close to this rating.

100% Freeze-thaw guarantee

Capillary Bunkers have been designed to withstand the most severe freeze-thaw conditions for decades without any damage. Special polymers are mixed in the truck that enhance the strength and durability, and provide ample protection from the most severe winter freezing conditions, in any climate, wet or dry.

This freeze-thaw strength has been proven in laboratory environments multiple times, but most importantly in the field, in real-life installations for over 10 years. For instance, this 18 hole top-5 course in Oslo, Norway has had almost all green side bunkers installed over 10 years ago and has suffered zero damage. This location is one of the toughest golf course sites you will ever find, with some very deep ground frost on wet clay soils that move with the freeze-thaw cycles every year.

Bunker Liner Costs

What is the extra cost of installing a Capillary Bunker Liner? The answer depends on local aggregate pricing and transport availability. On average, installing Capillary Bunkers usually means an added 15 – 35% to the total bunker renovation cost if you include labor, and in return the bunker will now last 5 times longer on average, even against other liner products.
