At the core of our solution, The Capillary Material, formerly Capillary Concrete, is a patented and engineered polymer-based concrete.
The meso-pores in the binding agent provide upwards capillary movement of water, keeping moisture levels optimal for sand, soil and growth of grass. The Capillary Material is researched and designed to be the optimal size of holes for moisture to travel at the right pace, and at the right time. As the size is just right for moisture to travel upwards, it also provides the opportunity to hold moisture in the ground profile even in dryer conditions.
Capillary breach occurs when the pore sizes of two materials do not match, and moisture will then not be able to move against gravity. Water will not move from a small hole to a large hole until gravity is strong enough to pull it down. Problem occurs when the ground profile is saturated and does not drain the excessive moisture properly. The Capillary Material is designed to avoid capillary breach and hence create the right moisture levels. The Capillary Material contains large pores that freely drain water by force of gravity, but are not too large in order to avoid migration of sand particles into the drainage system.
The Capillary Material enables the use of an open growing medium and moves water and nutrients against gravity at the bottom of the rootzone as a result of which the grass develops deep roots. Simultaneously it creates a firmer and drier surface which leads to reduced weeds and disease pressure.
Capillary Material testing shows how moisture moves in a dry sample (left) placed in moisture, to being saturated after 3 days (middle) and the sand sticking to the vertical face (right). The sand stays on the Capillary Material due to the capillary connection of moisture between the Material and the sand.
CC with GVY (zero suction)
Mainly adhesive hold water
The patented hydraulic geostructure of the macro- and meso-pores enable moisture holding in the ground profile, both over time and over large areas. This is optimal for growing strong grass, and allows for choosing the characteristics you want for the piece of ground depending on area of usage.
Creating infiltration areas to collect and distribute naturally filtered water
Collecting rainwater and using it over a long period of time for subsurface irrigation of a turfgrass area decreases strain on day water systems and is an environmental friendly choice to regular irrigation.
Perfect grass everytime
By using a fertilized and oxygenated moving water table for the The Capillary Material, it enables use of an open growing medium and moves water and nutrients against gravity at the bottom of the rootzone as a result of which the grass develops deep roots. Simultaneously it creates a firmer and drier surface which leads to reduced weeds and disease pressure.
Get rid of unsightly sprinklers, problems of water logging, over watering and damp spaces.
Spaces and sport grounds won’t have any downtime caused by the need for overhead irrigation. Instead, spaces can be utilized even more.
Irrigating from below avoids waterlogged surfaces. It makes them perform with an even consistency and they are less prone to diseases.
Using drip lines and regulating the size of the underground basins and the properties of the Capillary Material gives the possibility to choose the moisture level that is optimal for the intended use case of the ground.
In many cases surface moisture erodes performance of the ground. A subsurface irrigation system keeps the moisture levels at the surface at a level where weeds, fungicides and other diseases can be kept away.
By using subsurface irrigation and distribution of fertilizers and pesticides in the water there is no leaching of harmful substances or microplastics into adjacent soil, surrounding water streams or ground water. Additionally, the water consumption is up to 85 % less.
Total drainage control even after a storm
No leakage of fertilizers, pesticides and particles
No free-thaw damage
Top performance all year round
