CORE GRASS

Half turf

DESIGNED FOR DOMESTIC DRIVES AND ACCESS ROADS

Unlike other grass stabilisation grids, CORE Grass is environmentally friendly and has the strength to withstand high levels of traffic.

CORE Grass Reinforcement provides load bearing of up to 350 tn/m2 when filled, making it suitable for pedestrians, cars, 4x4s and even heavy commercial or emergency vehicles. The design of the grid allows for conventional maintenance of your lawn with ride-on or hand lawn mowers.

We also have supply ‘plug in’ markers to create parking bays, this system will comply with current UK building regulations for commercial car parks.

CORE Grass Reinforcement 60-40, features a unique lateral drainage system that allows water to move horizontally through the grid just below the surface. This allows stormwater to permeate evenly across the entire surface, protecting the turf from unnecessary erosion and providing even, consistent growth.

For best results we recommend that our CORE Grass stabilisation grid be fully filled with a soil/sand mix and seeded, giving the grass a chance to fully root into the grid. Alternatively if you don’t have 4-6 weeks for the grass to grow through there is a quick fix solution; partially fill the grass grid with soil/sand mix and then lay turf over the top of the grid and roll it into the cell structure.

 

CORE GRASS HD

DESIGNED FOR COMMERCIAL CAR PARKS & ACCESS ROUTES

Our CORE GRASS HD provides a load bearing of up to 280 tn/m2 when empty and over three times this when full (890 tn/m2), making it suitable for heavy vehicles and high traffic loads  in commercial applications.

CORE GRASS HD is made from pure grade HDPE which means that it remains permanently elastic enabling it to absorb immense pressure from heavy vehicles and livestock.

We also have supply ‘plug in’ markers to create parking bays, this system will comply with current UK building regulations for commercial car parks.

CORE GRASS PROTECTOR

DESIGNED FOR TEMPORARY & PERMANENT PROTECTION

CORE Grass Protector provides cost effective protection from wear and erosion caused by pedestrian and vehicular traffic without the need for excavation, it simply creates a separation layer between the user and the surface.

Perfect for both permanent and temporary applications, it can be used for overflow parking, DDA compliant and pedestrian access routes or light construction machinery.

It is quick and easy to install, simply pin to your existing grass surface and it is immediatley ready for use.

CORE GRASS Protector is best installed during the grass growing season between Spring and Autumn.  Ideally it needs to be fixed into ground that is well drained, firm and reasonably flat & level.

CORE GRASS & CORE GRASS HD BUILD UP

This diagram shows the tyical build for a CORE Grass Reinforcement installation. The grid can either be overfilled with top soil and seeded, or if you don’t have time to wait for the grass to grow, the grid can be partially filled and then turf can be laid and rolled into the grid.

HOW TO CALCULATE YOUR SUBBASE DEPTH FOR CORE GRASS & CORE GRASS HD

STEP BY STEP GUIDE FOR CORE GRASS & CORE GRASS HD

STEP 1 – Create a sub base suitable for the intended traffic load taking into account your sub soil ground conditions, then blind over the sub base with sharp sand to form a continuous smooth base level.

STEP 2 – Lay the grids and clip together to form one continuous matrix.

STEP 3 – Fill the grids with soil and damp down with water to allow soil to settle into the cells.

STEP 4 – Surface dress the cells by covering with approximately 10-15mm of soil loam mix.

STEP 5 – Seed the area and water thoroughly. To aid grass growth, cover the seed with a top layer of fertilizer and water regularly for a period of 4 to 6 weeks. Alternatively turf can be laid over/into CORE Grass Reinforcement to provide a lawned surface that can be used immediately. Simply lay the CORE Grass Reinforcement grids, fill 80% of the depth of the cells with a loose soil mix then lay the turf over the grids. Pass over the surface with a vibrating roller so that the turf sheers into the grids, providing an instantly usable surface.

INSTALLATION OF CORE GRASS PROTECTOR OVER EXISTING GRASS

CORE GRASS Protector is best installed during the grass growing season between Spring and Autumn.  Ideally it needs to be fixed into ground that is well drained, firm and reasonably flat & level.


STEP 1 – Once you have identified the area in which your CORE grass protector will be installed, cut the existing grass on the shortest setting and remove any clippings by rake, garden vacuum or leaf-blower.

STEP 2 – If needed, level out the existing area by filling in ruts or divots with a 70:30 mix of sharp sand and topsoil and compacting. At this point apply grass seed, following the seed coverage instructions set out by the seed supplier, following installation overseeding can be carried as required.

STEP 3 – Before laying the, CORE GRASS Protector we would recommend unrolling it and leaving for a minimum of one hour to help the mesh regain its flatness to avoid any rutting. The CORE grass protector can also be cut prior to install with garden secateurs if required.

STEP 4 – Install the CORE GRASS Protector directly onto the existing ground, butting up any joins or additional rolls to avoid overlapping. If the installation is carried out in spring or summer, it is recommended that a 15mm gap is left between adjacent rolls and that rolls are pinned individually.

STEP 5 – Pin the mesh to the ground with our metal pins or plastic anchors following our pinning diagram, which contains the recommended location of pins and how many are required per roll.

STEP 6 – Install the first row of pins along the longest edge of the roll starting in one corner, ensuring that the mesh is as taut and flat as possible to avoid a ripple effect in the mesh.

STEP 7 -Subsequent rows of pins should be inserted in the same manner as above in accordance with the pinning diagrams shown for your type of installation

U Pins are best used on shallow or rocky ground as these are not likely to snap during installation.

J Pins are best used on soft clay areas as these are sunk deeper into the ground, providing optimal pull resistance.

Plastic Anchor Pegs are best used when there is a danger of underground electrical cables or in equestrian settings and should not be used to join two rolls. If two rolls are to be joined with a “butt-joint” we recommend using U Pins to provide the best joint, if using plastic anchor pegs each roll should be pinned individually following the pinning diagram.

STEP 8 – CORE grass protector can be trafficked straight after install if necessary, providing it was fitted on well drained, firm ground. Once the grass starts to grow through the mesh it can mowed, seeded and treated as normal. Best results are obtained by restricting trafficking until after the grass has thoroughly established through the mesh and has been cut several times.


CORE GRASS Protector meshes have been designed to reach their full working potential in the quickest time-period with areas that have an established grass structure.

When it is the intention to lay the mesh in a region that is devoid of grass, and the area is going to be seeded to establish grass, time will be needed for the grass to develop a strong grass root structure before the mesh is planned to be used.  This is usually a full growing season – March to October.

CORE GRASS Protector can still be laid on the new growing grass and the grass allowed to grow into the mesh.  It would be advisable that a test is done with a pin on site to make sure the pin will stay in place as there would be no existing grass root structure to help to hold the pin in place. This can be a problem especially with sandy soils.

Installation during hot weather,  may cause the roll to expand and ripples to occur in the mesh.  This is quite normal and the mesh will settle down as the temperature cools and the grass grows into the mesh.

INSTALLATION OF CORE GRASS PROTECTOR OVER NEWLY SEWN AREAS

STEP 1 – Level and compact the existing soil surface, clearing off any debris.

STEP 2 – If required, put down a layer of good quality top soil and seed the area, again compacting the area to provide a firm base.

STEP 3 – Before laying the, CORE GRASS Protector we would recommend unrolling it and leaving for a minimum of one hour to help the mesh regain its flatness to avoid any rutting. The CORE grass protector can also be cut prior to install with garden secateurs if required.

STEP 4 – Install the CORE GRASS Protector directly onto the existing ground, butting up any joins or additional rolls to avoid overlapping. If the installation is carried out in spring or summer, it is recommended that a 15mm gap is left between adjacent rolls and that rolls are pinned individually.

STEP 5 – Pin the mesh to the ground with our metal pins or plastic anchors following our pinning diagram, which contains the recommended location of pins and how many are required per roll.

STEP 6 – When CORE grass protector is installed on a newly sown surface, we highly recommend that you avoid using the area for 4-6 weeks until grass has grown through the mesh, maturing enough for it to entwine with the mesh.
