How It Works

Bunker Liner Costs

What is the extra cost of installing a Capillary Bunker? The answer depends on local aggregate pricing and transport availability. On average, installing Capillary Concrete 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.

What Our Customers Say

95% of Our Customers Highly Recommend Us!
  • “All of our bunkers were completely redone with Capillary Bunkers. We got 100 inches of rain the last 2 years and for the last 4 to 5 years we have not had to replace any sand. We have less labor fixing washouts…we have to rake our bunkers fewer times…so it saves us a substantial amount of money for labor. ”
