Fibre Reinforced Turf from Inturf
The Toughest Turf for Pitches and Places That Take the Hardest Pounding.
Fibre reinforced turf is natural turf growing in a synthetic fibre reinforced rootzone. It has been designed to achieve greater use out of natural turf by increasing the load bearing and wearability of the natural surface.
This is achieved by blending together sand, organic matter and 35mm long polypropylene fibres to produce a homogeneous rootzone, known as Fibreturf rootzone.
In most cases, because of the dimensions of the turf roll, the fibre reinforced turf will be ‘lay and playable’ immediately.
“How can you play on a pitch you can't stand up on?”
Where it Works
Fibre reinforced turf is great for any area which is better grassed but which suffers from the most wear and tear such as:
- Equestrian businesses and ménages
- General landscaping and amenity areas
- Public and private gardens
- Grass verges subjected to occasional vehicle movement
- Overspill car parking
- Access routes to industrial sites via recreation fields
- Fire Engine access routes around prestige office, industrial or educational buildings
- Landing strips
- Winter sports
How it Works
The three components of the fibre reinforced turf rootzone all have important but separate functions:
- Sand gives the rootzone its necessary free-draining characteristics so that any surface water resulting from heavy rainfall is removed as quickly as possible - for example in a flash flood! The grade of silica sand selected may vary dependent upon end-use, but in all cases will have been produced in a hydraulic classification process to give a clean, narrow-graded material.
- Organic matter provides the nutrient source vital to healthy growth of the grass plant. It also provides a moisture buffer which is particularly important during dry periods of weather.
- Polypropylene fibres give immense three-dimensional strength and stability to the rootzone and being rot-proof they can be considered to act as a mass of indestructible synthetic roots both reinforcing and protecting the natural turf roots. The fibres have a dramatic effect in reducing surface deformation and compaction effects due to loading from foot-traffic or vehicles and also in minimising surface break-up due to the tearing action of ‘studded’ sports footwear and equipment.

and to conserve water
CBR values (Californian Bearing Ratio) will provide the necessary information by evaluating the strength of the sub base. If this technique is unavailable appropriate assessment of the sub soil type should be made, e.g. can it be described as light, sandy and relatively free draining or on the other extreme, heavy clay and poor draining.
Prepare lower rootzone, sub-soil or sub-base to specified levels and gradients. It may be that an excavator is required depending on finished levels. Transfer the reinforced rootzone (delivered in premixed condition by bulk tipper vehicles to suitable tipping area adjacent to site) in dumper truck from the stockpile and begin tipping at one end of formation.
Begin spreading reinforced rootzone using a tracked excavator or dozer ensuring that no machinery movement occurs on the prepared formation base, i.e. all movement restricted to the reinforced rootzone. Further delivery of reinforced rootzone can then be made by dumper travelling over the previously spread reinforced rootzone, preferably via plywood boards.
Place reinforced rootzone to appropriate level and complete even, light consolidation to the specified final depth using either the tracks of the spreading vehicle or a rotary rake. Compaction ratio is 0.75, e.g. 100mm as laid will compact to 75mm. Any obvious depression revealed by compaction should be filled in with further reinforced rootzone or the existing material can be redistributed locally. The surface should then be given a final levelling and finish using a power driven rotary rake, e.g. Blec Rotary Stone/Sand Raker which is available in both tractor drawn and self-propelled, pedestrian versions. The surface is then ready for turfing.
Fibre reinforced turf comes in 0.6 metre or 1.2 metre wide big roll sizes with optional lengths subject to application and the turfgrass specification has been designed to withstand heavy wear and tear. Carbon capture varieties that are deep rooting are also another useful feature of Inturf’s mixture.
It will almost certainly be necessary to irrigate the turfed area at regular intervals during the establishment period with the frequency of irrigation determined by prevailing weather conditions, i.e. ranging from no irrigation during wet periods to daily during dry periods.
A hot weather warning
We put so much effort into growing excellent turf, and our customers put so much into laying it, that the last thing we want is for people to lay turf that is doomed to fail.
So, if the daytime temperature is consistently over 20◦ and the humidity is high, the thousands of little grass plants in the turf roll (there could be up to 850 plants per square foot) will struggle to establish and flourish. It will be best to wait until things change to lay the turf, for example a fall in temperature is predicted or rain is promised. (Of course, established turf will bounce back from even prolonged periods of heat and drought and look as lovely as ever.)
Follow our advice and your new turf should do well and add real value to your garden or landscape. Ignore it and all your hard work could be for nothing.
