Capillary Wash Box

Restore sand to its original playing state and colour by washing it

Eliminate sand replacements and reduce touch-ups of your bunker sand by washing it instead

The Capillary Wash Box is an effective solution for washing algae, debris, silt, clay, and organic pollutants from bunker sand. By doing so, it preserves the sand’s percolation rate, colour, and desired playing properties while eliminating the need for frequent sand touch-ups and replacements.

The Capillary Wash Box: part of our complete bunker protection system

Protect your investment in bunker sand by washing it instead of replacing it

CapillaryFlow Bunker Liner

Drains with a rate of more than 100 inches per hour and moves moisture back up, preventing washouts and sand escaping from faces

The only bunker liner with the possibility to wash the sand

  • CUTTING SAND COSTS BY ⅔
  • IMPROVING AESTHETICS
  • RESTORING DRAINAGE & PLAYABILITY TO OPTIMAL STATE

About CapillaryFlow

Our Vision

A world where building low-maintenance natural spaces for sport and leisure is easy and sustainable.

Our Mission

Provide sustainable, durable and trouble-free greens and grounds for sport and leisure

We are a technology company whose patented innovations are enabling golf courses, sports grounds, and other leisure spaces like city parks to build long-lasting and low-maintenance greens, bunkers and grounds.

Controlling the water, carbon dioxide and oxygen levels for various soil profiles in these spaces is a major challenge. Our proprietary CapillaryFlow technology offers a simple solution that ensures optimal moisture levels and good drainage regardless of the weather conditions.

Capillary Material is the common factor across most of our solutions including Capillary Bunkers, Capillary Hydroponics, and Capillary Geothermal. It is a patented and engineered polymer-based concrete that is the only building material that can move water both up and down to precisely regulate the moisture content of any adjacent material, such as sand or soil.

 

From golf courses to sports fields, equestrian arenas and city squares

Over the last 15 years, our innovations have transformed the way the golf industry constructs bunkers and greens. It was but natural for us to progress into adjacent fields.

We understand the challenges of constructing, maintaining and regulating moisture levels in golf courses, sports fields, equestrian arenas and city parks and squares. Everything we develop is tested in real-life situations – over and over again. We work with some of the most advanced laboratories in the world to develop the best and most effective solutions for our customers.

Significantly less and easier maintenance

STEP 1

Install Capillary Concrete Bunker liner and Capillary Wash Box

The installation process is quick and efficient and the bunkers are ready to be used in 24h.

STEP 2

Use the bunker

With its superior drainage capacity the bunker will have increased playability and significantly reduced maintenance.

STEP 3

Wash the bunker sand

Expose the Wash Box and install risers to create the "chimney" above the sand surface.  Use a high-pressure water hose to wash the sand. Smaller particles will pass through the Wash Box leaving larger sand particles clean of contaminants.

STEP 4

Offer a great performance

Every season your bunkers will look - and behave - as they were brand new - without the need of replacing any sand.

 

Installation Guidelines

The Capillary Wash Box is installed in the Vault in the lowest part of the bunker. If your vaults already exist, please disregard step 2.

  1. Locate the drain-pipe in the bunker and select the lowest point of the bunker floor atop the pipe for the location of the Vault (if Vaults already exist, please locate the Vault and move to step 3).
  2. Remove the sand and cut out an area approximately 1 ft wide and 3 ft long and remove the Capillary Concrete.
  3. Remove drain gravel, dirt and completely expose the pipe.
  4. Cut a hole in the top of the pipe, approximately 2 inches wide and 6 inches long in the center of the Vault so it will be in the center of the Wash Box.
  5. Place the Wash Box with the lid mounted on it on top of the pipe, making sure it is set all the way down to the top of the pipe and that the top of the lid is below the top level of the Capillary Concrete in the bunker floor.
  6. Cut a piece of fabric large enough to cover the walls of the Vault and cut an X in the middle and slide it over the Wash Box.
  7. Backfill the Vault with clean bunker sand.

 

Washing Instructions

The Capillary Wash Box and this system is designed to only remove organic material (algae, clippings, leafs etc.) and particles smaller than 0.05 mm, which will float in water for some time.These are the particles that can darken color and slow infiltration rates. They can effectively be removed by following the washing Instructions.

  1. Locate the Vault with the Wash Box and remove the bunker sand to expose the lid.
  2. Remove the lid and place enough Extensions (the middle part of the Wash Box) to where the top of the last Extension is above the top of the sand surrounding the Vault.
  3. Connect a hose with a nozzle to the irrigation system and start by washing the immediate area surrounding the Wash Box to make sure the sand layer is never above the top edge of the Wash Box Extension. This must be done from time to time while washing not to have larger sand particles enter the drainage pipe.
  4. Now start as far away from the Wash Box as possible and wash the sand with a water beam from the nozzle that is at least 2 ft wide.
  5. Work the water beam so that the sand does not displace too much, merely gets turned around and washed in its place. You may have to push the dirty water along to reach the Wash Box from time to time.
  6. Be sure to wash all the way to the edge of the bunker as there is often an excess of sand locate there and we seek to re-establish the original sand depth and edge.
  7. On steeper faces, be careful not to wash too deep if not necessary as the sand will have to be pushed back up the face after washing.
  8. From time to time, check the drainage pipe in the Wash Box to make sure larger sand particles do not wash into the pipe and clog it. Some particles will inevitably reach the pipe, and the pipe must be washed clean by directing the water beam into the pipe, but this should not have to be done more than once or twice and after completing the entire bunker when the pipe must be cleaned at least for 5 minutes.
  9. After completion, the sand must be pushed back to ensure a uniform sand layer in the bunker, and often times new, clean sand must be added to reach the desired sand depths throughout the bunker.
