NATURALLY THE ANSWER FOR INCREASED USAGE

HYBRIGRASS is the ultimate marriage between natural grass and synthetic grass. It combines all the benefits of a natural grass playing surface with the strength and durability of synthetic grass. The HYBRIGRASS system consists of high quality Omega synthetic grass fibers, tufted in a special patented backing incorporating over 50% voids. HYBRIGRASS truly provides the optimum grass reinforcement system whilst not reducing the growing conditions for the natural grass.

HYBRIGRASS carpet is installed on a carefully selected root zone layer and filled with a specifically defined root zone mixture before high quality sports field grass seed is drilled into the surface. The natural grass grows between the synthetic grass fibers creating a strong and vigorous playing surface. The ‘open’ texture of the backing ensures that the grass roots are not obstructed in their vertical movement downwards from the day of installation.




Meeting International Standards

One of the major design challenges for HYBRIGRASS is for the system to meet the International Football Standards. As with all natural grass reinforcement systems, HYBRIGRASS is recognised as a natural grass playing surface according to the main regulating sports bodies such as FIFA, UEFA, WR, GAA, FIH. No specific international standards are applicable other than specific regional natural grass playing surface standards.
HYBRIGRASS surfaces are designed to meet local natural grass standards and also meet the FIFA Quality standard for synthetic turf surfaces. This proves HYBRIGRASS is the best of both worlds and guarantees a playable surface under all conditions and at all times!

Features

The HYBRIGRASS range of products is differentiated in 3 versions by the face weight or fiber density:

  • HYBRIGRASS 50 SS 14
    46.200 filaments/m²
  • HYBRIGRASS 50 DS 10
    66.000 filaments/m²
  • HYBRIGRASS 50 DS 13
    85.800 filaments/m²
Typically, a higher fiber density generates increased shear strength in the playing surface and a better technical and visual performance of the system under high wear conditions. The choice of the type of HYBRIGRASS is dictated by the customers design brief and required usage pattern.


Science Behind HYBRIGRASS

It has been proven that grass roots contribute considerably to the penetration resistance of the top layer of sports surfaces (Van Wijk, 1980). The reinforcing action of the grass roots can be explained from the high root intensities in the top layer and the tensile strength of the roots itself. When a stud of a football boot is inserted into the root zone, the soil material under the stud is displaced upwards and in lateral directions along certain shear planes (see figure).

The tensile strength of the roots crossing the shear planes will avoid or reduce this lateral displacement. In the analogy, the synthetic fibers of HYBRIGRASS are designed in such a way that no lateral displacement of the soil will take place, even when the natural grass component of the system has worn out.


According to field investigations a penetration resistance of the top layer of 1.4 MPa implies a soil strength that is adequate for intensive playing. Soil strength values can be affected by:
  • The bulk density of the soil
  • The amount of organic matter in the soil
  • The soil moisture conditions
  • The grass cover and grass root system

Using a reinforced natural grass system like HYBRIGRASS contributes to a better environment. Once established, HYBRIGRASS consists for up to 90% of natural grass and hence contributes to CO2 reduction in the atmosphere. The cooling effect of natural grass caused by its respiration, benefits to the direct, often urban, environment as well as to the well-being of the players.

Compared to synthetic grass systems, the lifespan of HYBRIGRASS is minimally doubled and hence reduces the environmental impact of producing synthetic turf carpets dramatically.

All of Hatko’s manufacturing is powered by Hydroelectricity hence contributes directly to a better environment.


Installation

HYBRIGRASS installations are typically turned around in 5-7 days when seeded in-situ or 2-3 days when pre-grown HYBRIGRASS turf/sods are used. The HYBRIGRASS carpet is unrolled on a level and consolidated lower root zone layer in 4-meter-wide rolls. Unlike other hybrid turf systems, the HYBRIGRASS rolls will be jointed via a unique glue connection, leaving no vertical or horizontal obstruction for grass roots to develop. Once the carpet is installed the infill mixture is applied in layers of 6-8mm whilst brushing up the fibers. Due to its unique shape and properties, the Hatko Omega fiber stands up naturally and requires very limited abrasive brushing. The total required infill depth is 35mm loose bulk (32mm consolidated).

Design, Build & Maintenance

Our HYBRIGRASS engineering service provides customer support from defining the initial design brief to preparing the working design, to execute the installation and maintenance. Our experienced engineers will be able to translate the client’s requirements into the best design whilst taking into account local conditions, restrictions and available construction materials.

Our in-house construction and installation crews guarantee a smooth and on time installation, where most competitors have to rely on their subcontractors and supplier’s availability.




Alliance Of The Experiences!

Rob de Heer, who has over 20 years' experience as developer of re-turfing techniques and hybrid grass technology, and HATKO, which is one of Europe’s leading producers of synthetic sports surfaces, brought together their experience to create “HYBRIGRASS”

Our engineers have developed natural grass reinforcement systems, later named Hybrid Turf Systems, from 1990 onwards. We pride ourselves to have successfully implemented hybrid grass systems in some of the major stadia in the world.

After many years of research and experience Rob decided to join forces with HATKO. The philosophy behind this decision is to unite Rob’s hands on experience and HATKO’ s production technology. In HYBRIGRASS all the elements come together from initial pitch design, specific carpet production technology to management of hybrid grass systems.
