All testimonials

Kinderlou Forest GC

Heath Allen

We used sand from an on-site quarry instead of shipping very expensive one to our location. We tested the sand, and found that its performance was marginal, but by using the Wash Box to remove fine particles, it became much more acceptable, and its performance was much better. Good quality bunker sand is expensive, so doing this obviously saved us  a lot of money, and those savings will continue for the lifespan of the bunker.

Hoover Country Club

LJ Robinson

The Wash Box is a huge deal for us. In the past, after a flood, we would skim our bunkers with flat shovels, but there was always some muck left over. With the Wash Box, we can skim, then connect a hose to the irrigation system and blast out the rest of the contamination. It will make a HUGE difference for us!

Castelconturbia GC

Giovanni Malcotti

When our contractor explained the benefits of the Wash Box to us, it was an easy decision to add it, one we took in an instant. It was a complete no brainer and we are happy with how it has helped us restore the sand colour without removing or adding any new sand!

Delsjö GK

Kevin Collins

Keeping our sands clean with the soils we have always has been a huge problem. Regardless of how good your construction is, you will always get contaminations in the sand here: clippings, algae, clay and silt run-offs and the like. This is the first solution we have ever seen work where we do not have to replace the sand. I'm stunned by the results and also all the money we save on sand!

The Breakers Palm Beach

Mark Reid

I am a big fan of the Wash Box. To have the ability to remove fines and algae, and bring sand back to its original pure-white state is amazing. I’m never worried about bunker consistency now!

Golf Course Updates:

The rain total for yesterday was 2 inches. It was a great test for the renovated bunkers and they handled it flawlessly!

Not a brilliant morning weather wise, but delighted at how the course has held up to an inch of rain since we left yesterday.  Greens drainage and capillary concrete bunkers are performing well.

Headland Golf Club

Ben Tilley

When 38mm “floggs down” overnight & 55mm over 3 days & then you come in to find your decision making, choices of product and planning have been vindicated 😎😎😎

Clearwater Bay Golf & Country Club

Clearwater Bay Hong Kong after Super Typhoon I rest my case for Ecobunker & Cappilary Concrete use 👍👏👏

Ayla Golf Club

Atilla Demisroy

Keeping the white silica bunker sand and the orange/brown desert sand separate is essential if bunker performance is to be maintained, and this requires a quality liner. We need separation to keep the integrity of our bunkers. CapillaryFlow was the only option to fix this.

Oakwing Golf Club

Kyle Swart

Before we started, around fifty per cent of our bunkers simply didn’t drain. In the first three months after we renovated, we had 22 inches of rain–we went from an incredibly dry summer to an incredibly wet winter. There is not a bunker out there that has held water or washed out, or retained any silt. They have been the best addition to this golf course.

We are going to save $50-70,000 a year just on labour from the new bunkers, and there will be another $12-15,000 from not having to replace sand. For us, that is a big, big difference.

St. Joseph CC

Wyatt Burnett

In case you wanted to see capillary concrete vs 17 year old bunker solutions. It nots a fair fight at all! These bunkers are about 100 yards apart. #capilaryconcrete

Clearwater Bay Golf

Peter John Downie

After 250mm of rain, no washout, no nothing. The Bunkers we didn't redo, a complete mess. Washed out, right down to the sand mat, completely depressing for the staff. After this, we will redo all our bunkers with Capillary!

Knightsbrook Golf Resort

if every bunker in the golf course had Capillary, it would make life so much easier.

Newnan Country Club

Andy Scott

We’ve had three big rainstorms – three inches overnight – since we finished the installation, and we have come in the following morning and found little or no washouts in our new bunkers. Member reaction has been great. I’m getting compliments every single day about how they look and play. It’s probably too early to say this is the best decision of my life, but I’m pretty close to it.

The Club at Gettysvue

Jeff Dudych

During my travels I’ve seen all the liners and from talking to my colleagues, it was clear that the Capillary Bunkers stood up the best.

Wakefield Plantation Country Club

Todd Lawrence

I like the fact that the concrete is a homogenous two inch layer. Other products seemed to depend much more on the contractor to get the consistency and depth of the product right. With Capillary Bunkers, I knew that as long as it came out of the truck properly mixed, it would give me that solid two inch layer.

Sarabay Country Club

Carlyle Merring

We had ten inches of rain over the course of thirty days in June, and seven of those inches came down in two days,” says golf course superintendent Carlyle Merring. “The bunkers stood up to it really well. We don’t have a problem with them washing out. The integrity of the product is holding strong – not failing in any sort of way, and the bunkers are functioning really well. Generally we can get our bunkers back in play in one morning after a big rain event.

Kinderlou Forest Golf Club

Heath Allen

We want to do this one time and not have to worry about going back in to replace anything. And the Capillary sytem is very easy to install – there are very few restrictions about suitable weather, or time of day, and so on.

Cuscowilla Country Club

Jarrod Clark

After 20 years of weathering and maintenance our bunkers were in need of renovation. We have a natural style of bunkering and wanted to keep that look intact while installing new sand and drainage. Using Capillary Concrete on our steep faces allowed us to stabilize and drain the bunkers while keeping the design and look intact. We have experienced less washouts and better playability since the Capillary Concrete installation. Our members have been very happy with the consistency of the new bunkers that are now playable sooner after heavy rainfall

Flying Horse Club

Phil Smith

I have had great experiences with Capillary Concrete, so it was an easy decision for this project. I have found the Capillary Concrete to deliver very good results in terms of sand quality, and the easy of installation just closes the deal as far as i’m concerned. I really can’t say enough about it.

Gamle Fredrikstad Golfklubb

Agne Strom

I dug up the sand today in one of our bunkers. I am turning it into a chipping area by green #7. After 3 trouble-free seasons and 2 winters I can testify of zero damage to my Capillary Concrete. I strongly recommend this product! Never a wash-out. I spend about 10 hours per week on my 45 bunkers and that's it.

University of Texas Golf Club

Tyler Andersen

As a staff, we needed to find a way to retain moisture in the faces of the bunkers so golf shots would hit and release to the bottoms of the bunker. Capillary Bunkers with its two-way moisture control was the only liner who could provide this. We couldn't be happier for our bunkers!

The Preserve Golf Club

Steven Miles

All of our bunkers were completely redone with Capillary Concrete back in 2014. 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.

We have not had to repair our bunkers at all, and, incredibly, the original sand is still in them. Since 2014, I have bought one truckload of sand, and that was for the bunker in our chipping green – which gets blasted out by players. Our bunkers have flashed sand faces, but our minimal washout issues only occur where water actually flows into the bunkers. When we get a big rain – and eight to ten inches of rain is not uncommon – we have to wait for the drainage infrastructure underneath the bunkers to catch up with the bunkers’ ability to move water. But it always does, and then the crew can prepare the bunkers for play again.

Avondale Golf Club

David Warwick

We have recently made the huge decision to renovate all the bunkers at Avondale Golf Club, utilizing Capillary Concrete™ as the primary bunker liner and the patent pending drip line irrigation technique on the steeper faces. We are extremely impressed with the effectiveness of the product.

Palmetto Golf Club

Brooks Blackburn

It’s been a game changer for us.

Mount Vintage Golf Club

Rodney Crow

Since installing Capillary Bunkers, we are seeing superior conditions, the moisture levels seem to be staying right where we need them — never too dry or too wet — and our members have absolutely raved about them. The difference between our Capillary Bunkers and the ones we haven’t renovated yet is night and day.

The CapillaryFlow difference

What sets our services, bunker liner and full-scale protection system apart

No certified installers needed - Work with any contractor or your in-house crew

Our products are so easy to install you can either do it yourself, your contractor of choice, or one of our partners. 

Prevent washouts with the highest drainage rate in the market

Unlike some geotextile or synthetic liners that are impermeable and has to move water to the bunker drainage lines, our bunker liner drains throughout the full liner area with a rate of 100’/hour, so water can’t back up on the faces and cause washouts. 

The only liner that moisturize the sand from below in drier conditions

By capillary action moisture can move water up from the native soil into the bunker sand. Not only maintaining the right playability, but also helps keeping the sand on steep faces. 

Long-term choice: Highest durability, strength and life span of all bunker liners

ASTM of +3000 PSI is unparalleled in the market, providing an outstanding life span of the bunker liner. 

Possibility to wash the sand

CapillaryFlow’s bunker liner and protection system is the only one that allows for washing your sand - protecting you from expensive sand touch-ups and replacements.
