1. Capillary Concrete is a patented bunker liner that provides superior drainage and moisture control for bunker sand. 2. It is easy to install, long-lasting, and reduces maintenance needs compared to other bunker liners. 3. By keeping bunker sand consistently moist, it helps prevent washouts and keeps sand firm, reducing the need for sand additions.

5. Martin Sternberg
• Capillary Concrete® is a patented bunker liner
and a registered trademark invented by Martin
Sternberg, CGCS
• After years of working in bunker construction
and management, and having experienced every
single bunker liner product on the market,
Martin came up with the unique Capillary
Concrete® formula. He shared the constant
headaches of bunker management with every
superintendent he worked with and now
believes that Capillary Concrete® is the final
solution to all bunker problems.
"This product is very durable, environmentally safe and easy to install.
It drains perfectly and keeps the bunker sand moist and compacted.
And all this at a very reasonable price. This simply solves all bunker
problems!"- Martin Sternberg, CGCS

6. Capillary Concrete®-Reduces
Maintenance and Saves Money
• Easy to install: Capillary Concrete® is mixed thoroughly offsite and can be delivered to each bunker in a 3m3
Concrete truck and this is followed by simply spreading the Capillary Concrete® at a uniform thickness of 50mm
• No Messy clean-up with fuel or other carcinogenic liquids
• No odor
• 90% strength in first week and remaining 10% in the next 10-15years-
• All structural building, roadways etc. are built utilising concrete and not asphalt or polymer based products
purely for strength and lifespan
• Tested in various countries in different climatic conditions
• Superior Drainage: The open architecture provides maximum drainage and water flow to minimize washouts
even on the steepest of bunker faces.
• No contamination of clay from sub-grade: The 50mm layer of Capillary Concrete® prevents sub-grade migration
to help keep sand clean.
• NON OF THESE PRODUCTS PREVENT PLUGGING 100%, HOWEVER, WITH ADDED MOISTURE IT SURE REDUCES.

8. Concrete in general is widely accepted as the strongest material available to
create outdoor structures. There is a reason bridges, parking garages and
airfield runways are always constructed out of concrete... - it lasts!

12. Delivery
Capillary Concrete ® can be
delivered to each bunker or it
can be offloaded into tractor
and trailers dependent on
access. Capillary Concrete® can
be left held in the trailer for up
to 45mins.

13. Application: 6 Easy Steps

5. Allow to cure for 6
hours
6. Install sand and get
back to play

14. Moisture
Moisture is the key factor in the
installation and maintenance.
Moisture is retained over 100% of the
sand surface i.e the faces and base

15. Drip line Irrigation
Capillary Concrete® has
developed a revolutionary
technique of subsurface
irrigation on steep bunker faces,
which is part of the Capillary
Concrete® patented system, and
it is changing the way bunkers
are being managed. There is no
need to irrigate the bunker faces
to achieve firm conditions. The
drip line irrigation used in many
installations is Netafim
Techline®, and the amount of
water emitted is determined by
the design and the bunker
condition.

16. All bunkers are now automatically
controlled

19. WET SAND v’s DRY SAND
• Wet sand tends to be
firmer
• Wet sand doesn’t fall
during hot dry
weather

21. FINISHED PRODUCT
• Moisture control is the ability to freely drain
rain events and to be able to keep moisture in
the bunker sand in dry conditions.
