Estabilización de Suelo para Uso Ecuestre
Mantén los caballos sobre hierba, y conserva la hierba
Paddocks que sobreviven al invierno. Las rejillas IBRAN refuerzan el suelo bajo la capa vegetal para que accesos, senderos y paddocks se mantengan con hierba en lugar de convertirse en barro.
Por qué importa el refuerzo del suelo aquí
Los caballos deterioran la hierba de una forma que ningún otro uso iguala. Un animal de media tonelada sobre cuatro cascos concentra más presión sobre el suelo que la mayoría de los vehículos, y a diferencia de un vehículo permanece en el mismo punto durante horas, redistribuye su peso y vuelve al día siguiente.
La hierba aguanta eso en verano. No puede aguantarlo en enero, cuando el suelo está saturado y la capa vegetal no crece. El tapiz se rompe, la zona radicular se desplaza lateralmente, el agua llena el hueco y en pocas semanas un acceso con hierba se convierte en barro pelado que no se recupera hasta mayo.
Por eso gran parte de la gestión invernal es, en realidad, gestión del barro: caballos recogidos antes de lo que se quisiera, paddocks en reposo que se necesitaban, patas lavadas cada día y una resiembra de primavera que vuelve a deteriorarse el invierno siguiente.
Una rejilla celular cambia la mecánica. La zona radicular queda confinada en celdas cerradas que impiden su desplazamiento lateral o su hundimiento en el terreno blando, y la carga se distribuye sobre toda la superficie en lugar de perforarla. La hierba crece por encima de las paredes de las celdas, las raíces se anclan en un perfil que permanece intacto y el tapiz sobrevive a condiciones que de otro modo lo destruirían.
El prado sigue siendo un prado. Ese es el objetivo.

Por qué hierba y no piedra
Ambos rellenos funcionan en la misma rejilla, y en una propiedad ecuestre la respuesta con hierba suele ser la correcta.
La hierba mantiene una superficie natural bajo los cascos, que es para lo que están diseñados los caballos y lo que la mayoría de los propietarios desean. Conserva el terreno como zona de pastoreo en lugar de convertirlo en firme duro, lo que importa para la clasificación de la finca, su aspecto y los usos futuros. Y evita colocar material suelto en zonas de paso de caballos: la gravilla puede moverse bajo los cascos, magullar las suelas o alojarse en un casco o herradura, por lo que donde no es necesaria es mejor no utilizarla.
La gravilla tiene su lugar en puntos concretos: aparcamiento de camiones y remolques de caballos, accesos al patio y el acceso al estercolero, donde un vehículo gira bajo carga y la apariencia importa menos que la previsibilidad. Cuando se utilice en zonas de paso de caballos, especifique una mezcla angular de granulometría fina enrasada al nivel de las celdas, no piedra grande ni redondeada, para que la superficie se comporte como una masa sólida.
En todos los lugares donde los caballos permanecen, utilice hierba.
¿Qué profundidad de rejilla elegir?
El número de una rejilla determina la profundidad de la zona radicular confinada, y para hierba bajo caballos esa profundidad es lo que decide si el tapiz se recupera.
- IBRAN®-X50 es nuestra recomendación para hierba ecuestre. La celda más profunda retiene más humedad y da más espacio a las raíces antes de encontrar una superficie sólida, por lo que el tapiz se recupera entre usos y sobrevive tanto al verano como al invierno. Es también la elección correcta en accesos y en cualquier punto donde giren vehículos.
- IBRAN®-X40 para senderos de uso ligero y entornos de refugios donde el tráfico de caballos es intermitente y no diario.
- IBRAN®-X30 cuando las cotas son ajustadas o se trabaja junto a un patio duro existente.
Las celdas poco profundas se secan primero y más rápido exactamente donde caen los cascos. En terrenos de uso diario durante todo el año, la celda más profunda realiza un trabajo real.
Sustrato radicular y mezcla de semillas
Utilice un sustrato radicular de base arena, no tierra vegetal sola. La tierra vegetal retiene agua y se compacta bajo los cascos, y un sustrato compactado asfixia las raíces precisamente donde la hierba está bajo mayor presión. Una mezcla de base arena mantiene el perfil abierto y drenante, de modo que el agua lo atraviesa y el aire llega a las raíces tras una semana húmeda de uso.
Rellene enrasado con la parte superior de las celdas, no por encima. La hierba crece sobre las paredes de las celdas y oculta completamente la rejilla, mientras las paredes permanecen listas para soportar la carga en el momento en que un casco aterriza.
En cuanto a la mezcla de semillas, especifique para tolerancia al desgaste y para los caballos que la van a usar. Una mezcla ecuestre o de uso intensivo de alta resistencia tendrá menos aspecto de césped en el primer año y un aspecto considerablemente mejor en el quinto. Cuando la laminitis o problemas metabólicos sean una preocupación en el grupo, consulte la selección de especies con su veterinario o un asesor de praderas antes de hacer el pedido, ya que el contenido en azúcar varía significativamente entre mezclas y es mucho más fácil elegir correctamente que cambiarlo después.
How it goes in
- Work out where the water goes. Gateways, troughs and shelter doors are usually the low point of everything around them, which is half the reason they poach. Decide now whether you need a cross-fall, a drain across the entrance, or somewhere for it to soak away.
- Dig the mud out. This is the step people skip and the one that matters most: poached ground has no bearing capacity, and building on it just buries the problem. Excavate to firm subsoil however far down that is.
- Lay a woven geotextile across the formation, lapping joins by at least 300mm. On soft ground it is doing structural work, stopping the sub-base punching down and stopping soil pumping up into the rootzone.
- Lay and compact an open-graded sub-base in 50mm layers. On very soft or wet ground you may need more depth than you expect, because you are building a raft rather than a surface.
- Blind with a thin levelling layer and screed it flat.
- Push-fit the grids together, staggering the joints. Cut to line at gateposts, troughs and fencing with a saw.
- Restrain the edges, and run the grids wider than the opening so the restraint sits outside the line hooves and tyres actually take.
- Fill the cells with a sand-dominant rootzone, level with the cell tops, brushing in so no cell is left hollow.
- Seed or turf, water in, and keep horses off while the sward establishes.
Full step-by-step detail is in our grass grid installation guide.
Letting the grass establish
This decides how the ground looks in year three, and it is the hardest part to be patient with on a working yard.
The surface is only as strong as the root structure holding the rootzone together. A gateway seeded in spring and turned out onto in June will look tired by its first winter; the same installation left through a full growing season will carry horses for decades.
Where the calendar will not allow it, use turf rather than seed, and phase the work so some areas establish while others carry the traffic. Doing gateways in the spring rather than the autumn gives the sward the whole summer before it is asked to do anything difficult.
How far to extend a gateway
Further than the gap. The instinct is to surface between the posts and stop, but horses and vehicles fan out as they come through, and so does the damage.
As a working rule, take it at least a horsebox length into the field and wider than the gate opening on both sides. Where horses queue at a gate waiting to come in, extend it on the field side to cover where they stand, not just where they walk.
Surface only the gap and you move the mud two metres, then have to lead a horse through it to reach the good bit.
Troughs, feeders and shelters
These are the other places horses stand still, and they poach for the same reason: constant occupation, no recovery time, and water arriving from somewhere.
A reinforced grassed standing around a trough or ring feeder pays for itself quickly, because it is a small area doing a lot of damage. Extend it beyond the reach of the horses using it: a metre and a half around a trough, and the full footprint plus a margin around a feeder.
At field shelters, the doorway and the strip immediately outside take the worst of it. Reinforce the approach as well as the entrance, and get the falls right so water runs away from the shelter rather than into it.
Turnout tracks and track systems
Track systems concentrate horses into a narrow route deliberately, which is excellent for movement and terrible for the ground. A track that works beautifully in September is often unusable by December along its whole length.
Reinforcement makes the concept work year-round. Grass-filled grids along the track keep a natural surface underfoot while stopping the rootzone shearing, and the confinement means the track holds up under the repeated, concentrated traffic it is designed to create.
Reinforce the whole loop if the budget allows. If it does not, do the corners, gateways, water points and any narrow section first: those fail long before the straights do.
Day to day management
Treat it as grazing, because that is what it is.
Top or mow it with everything else; mowers and toppers pass straight over because the cell tops sit below the growing crown. Muck can be picked as normal, and a barrow wheels across a firm level surface far more easily than across poached ground. Harrow with care and keep tines set shallow over reinforced areas.
Feed and overseed worn patches at the end of the season rather than waiting for them to spread, and check levels after the first winter, brushing any settled cells back up. The grid itself needs nothing.
Get it right first time
The one thing worth knowing: dig the mud out first.
Every failed gateway on every yard has the same history. Someone tipped stone into a wet hole because it was quicker than excavating, it sank into the soft ground over one winter, and by the next year the hole was back and deeper.
Anything laid on mud becomes mud. Excavate to firm ground, get the membrane in, build the sub-base in layers, then let the grass establish. Do that and the surface will still be there in twenty years. Skip it and you will be doing the same job again next autumn, in worse weather, with horses to move in the meantime.

Common Questions
Why do horse gateways and tracks poach so badly?
A half-tonne horse on four hooves concentrates more pressure per square centimetre into the ground than most vehicles do, and unlike a vehicle it stands in the same place for hours and returns the next day.
Grass copes with that in summer but not in January, when the ground is saturated and the sward is not growing. The turf shears, the rootzone is pushed sideways, water fills the hollow, and the area does not recover until spring.
Will the grass actually grow through the grid?
Yes. The rootzone is filled level with the cell tops, and grass grows up over the cell walls so the grid is hidden completely once established. Mowers and toppers pass straight over because the cell tops sit below the growing crown.
What changes is underneath: the rootzone is confined so it cannot be displaced sideways or trodden into soft ground.
Should I fill grids with grass or stone on a horse property?
Grass everywhere horses spend time. It keeps a natural surface underfoot, keeps land as grazing rather than hard standing, and avoids putting loose material where horses walk, since stone can move underfoot, bruise soles or lodge in a hoof or shoe.
Stone earns its place at horsebox parking, yard access and muck heap approaches, where a vehicle turns under load. Where stone is used near horses, specify a fine angular graded blend packed level rather than large or rounded material.
What rootzone should equestrian grass grids be filled with?
A sand-dominant rootzone, filled level with the cell tops, not topsoil on its own. Topsoil holds water and compacts under hooves, which suffocates roots exactly where the grass is under most pressure.
A sand-dominant mix keeps the profile open and free-draining so air reaches the roots after a wet week of turnout.
What seed mix should I use?
Specify for wear tolerance rather than appearance: a hard-wearing equine or amenity mixture looks less like a lawn in year one and considerably better in year five.
Where laminitis or metabolic issues are a concern in the herd, discuss species selection with your vet or a grassland adviser before ordering, since sugar content varies significantly between mixtures and it is far easier to choose correctly than to change it later.
Do I need to dig the mud out first?
Yes, and it is the step that matters most. Poached ground has no bearing capacity, so building on it just buries the problem deeper.
Excavate to firm subsoil however far down that is, lay a woven geotextile, then build the sub-base in compacted layers. Anything laid on mud becomes mud.
How far should a reinforced gateway extend?
Further than the gap itself. Horses and vehicles fan out as they come through and so does the damage.
As a working rule, take it at least a horsebox length into the field and wider than the gate opening on both sides. Where horses queue at a gate waiting to come in, extend it on the field side to cover where they stand, not just where they walk.
Can grids be used for a track system?
Yes, and track systems are a natural fit because they deliberately concentrate horses into a narrow route, which is excellent for movement and hard on the ground. Grass-filled grids keep a natural surface underfoot while stopping the rootzone shearing.
If budget will not stretch to the whole loop, do the corners, gateways, water points and narrow sections first, because those fail long before the straights.
How long before horses can go on it?
Allow a full growing season before winter turnout where you can, because the surface is only as strong as the root structure holding the rootzone together.
Where the calendar will not allow it, use turf rather than seed and phase the work so some areas establish while others carry traffic. Doing gateways in spring gives the sward the whole summer before it is asked to do anything difficult.
Can I still poo pick, harrow and top the area?
Yes. Muck can be picked as normal, and a barrow wheels across a firm level surface far more easily than across poached ground. Top or mow with everything else, since the cell tops sit below the growing crown.
Harrow with care and keep tines set shallow over reinforced areas.
Will reinforced turnout help with mud fever?
Persistent wet, dirty conditions underfoot are a recognised risk factor for mud fever and thrush, so keeping horses out of standing mud at gateways, troughs and shelter doors removes one of the contributors. A reinforced grass surface stays firm and drains rather than holding water.
It is one part of management rather than a cure, and veterinary advice should guide the rest.
