Vehicles on Soft and Light-Duty Ground Questions Checklist

Write down what is coming in plain terms, whether a car, a van, a lorry, a skip vehicle, a machine or lifting plant.

Each of those behaves differently on soft ground, and the description is the first thing anybody advising will ask for.

Ask whoever is sending the vehicle for its weight and how that weight reaches the ground, and record what they tell you.

The supplier holds this information routinely, and an owner is entitled to ask for it before agreeing to an access route.

Note whether the vehicle would be loaded, empty or both at different points, since it may arrive one way and leave the other.

A skip vehicle and a delivery lorry each change weight during the visit, which matters for the ground in different places.

Ask whether anything would be put down onto the ground, such as legs, outriggers, mats or props, and where they would sit.

Lifting plant concentrates its weight where it is standing rather than spreading it, and that position is a specific question.

Record how many visits are expected, over what period of time, and whether every one of them would follow the same route.

One crossing and repeated crossings along the same line are quite different, and the difference is easy to establish in advance.

Note who would be driving and whether they have seen the route, since the person on the day makes the actual decisions.

Plans made in an office are frequently revised by whoever is behind the wheel, unless somebody has walked the route with them.

Mark on a sketch where the vehicle would turn, and note whether it would turn on the spot or swing through a wider arc.

Turning concentrates effort in one place, and where it happens is something an owner can work out before anybody arrives.

Mark where the vehicle would stand still and for how long, including any time spent loading, unloading, waiting or lifting.

A standing position is a sustained load in one spot, which is a different proposition from something passing across.

Note whether reversing is involved and where, since a reversing vehicle takes a different line and often repeats it several times.

Reversing manoeuvres are where a route gets used two or three times rather than once, in the same narrow strip.

Note whether wheels would follow the same line each time, or whether the route could be varied to spread the effect.

Varying the line is one of the few things an owner can practically ask for, and it costs nothing to request in advance.

Walk the whole route yourself and note pinch points, corners, changes of level and anything that would force a particular line.

The constraints decide the manoeuvres, and walking the route is more reliable than looking at it from a window.

Write down what the ground is at the surface, whether lawn, gravel, a path, a light-duty paved area or bare earth.

The surface is only the visible part, but describing it accurately is where any conversation about the ground starts.

Record that what lies beneath is unknown unless you hold a record of it, and resist inferring the construction from how the surface looks.

A sound-looking path says nothing about whether the layers beneath were built to take a vehicle.

Whether any ground can carry a vehicle is a determination for a qualified professional and cannot be judged from appearance.

Note what the area was built for, if you know, including whether it was ever a drive, a path or simply garden.

A change from what a surface was built for is the thing that matters here, and the starting point is worth stating.

Record how the ground behaves in wet weather, including anywhere that stays soft, holds water or has rutted before.

Ground that has already shown how it behaves is the most useful information an owner can offer, and only they have it.

Photograph the whole route and every standing position from several angles before anything arrives, and put the date on each photograph.

This is the record that settles what the ground was like beforehand, and it can only be made in advance.

Note and photograph any existing rutting, sinking or damage so that what is already there is recorded rather than disputed afterwards.

An honest record of pre-existing condition makes the rest of the record credible and keeps the conversation straightforward.

Record what the weather has been doing in the period before the visit, and note whether the ground is currently wet or firm.

The state of the ground on the day is what governs, and it is worth writing down rather than judged in passing.

Ask whether the visit could be moved to drier conditions, and note the answer rather than assuming the date is fixed.

Waiting is often possible and is rarely offered, because nobody asks whether the date is a preference or a requirement.

Note whether the time of year matters for the ground and for any planting or lawn the route crosses.

Recovery of a lawn depends heavily on the season, which is worth considering when the date is still movable.

Ask what would happen if it rained heavily on the day, and whether there is a point at which the visit would be postponed.

Agreeing a position in advance means the decision on the day is a check rather than an argument.

Note whether the ground would have time to recover between repeat visits, or whether they would follow closely together.

Repeated use without recovery behaves quite differently from the same number of visits spread out.

Establish what services and drainage run beneath the route, and mark them on the sketch before anything drives across.

A pipe or cable under a wheel track is a predictable risk and an entirely avoidable one if its position is known.

Mark every cover, gully and chamber on the route and ask what happens where a wheel would cross one.

Covers set in soft ground were not necessarily built for a vehicle, and they are the most obvious thing to notice in advance.

Note where any trench has previously been cut across the route, since backfill rarely behaves as the ground around it does.

A line of reinstatement is among the most common places for ground to settle, and a wheel track over it accelerates that.

Note whether the route or the standing position is on, above or near anything holding a level, and treat that as a question to ask first.

A retaining structure does not distinguish between a car and a delivery lorry except in what each asks of the ground it holds.

Driving or standing a vehicle above or near retained ground belongs with a qualified engineer before it is agreed.

Ask whether any part of the route is a drainage feature, including a permeable surface, a shallow dip or a planted depression.

Driving across or stockpiling on a drainage feature can remove a function that nothing at the surface indicates is there.

Driving or standing on anything forming part of site drainage is a question for a qualified drainage professional before it is agreed.

Note any established tree whose rooting area the route or standing position may cross, and raise it before the visit.

Compaction over a rooting area is invisible at the time and shows in the tree long after the vehicle has gone.

Anything affecting an established tree belongs with a qualified arboricultural professional, and protection must be confirmed locally.

Write down before the visit what state you would find acceptable afterwards, and be specific about the areas you care most about.

An expectation set in advance can be discussed; one formed while looking at ruts is simply a complaint.

Distinguish between areas where marking would be tolerable and areas where it would not, and mark both on the sketch.

Spreading the same expectation across the whole garden makes it impossible for anybody to work to it.

Ask what protection could be laid down for the route or the standing position, who provides it and how long it takes to put down.

Protection is commonly available and rarely offered unless the owner raises it before the date is agreed.

Note whether repeated use would eventually justify building something, and record when you first started using the ground this way.

Overflow parking often becomes permanent by accumulation, and noticing that it has is the first step to doing it properly.

Where you decide a proper surface is needed, treat that as its own project involving the construction beneath rather than the surface alone.

A stronger surface laid over a foundation built for something lighter only delays the point at which the weakness shows.

Agree before the visit who is responsible for putting the ground back, and record what was said and by whom.

After the event the conversation is about blame; before it, the same conversation is about arrangements.

Agree what making good actually covers, including whether it extends beyond the visible surface to the condition of the ground beneath it.

Reseeding a lawn addresses appearance, and whether anything else is included is exactly the point worth settling.

Agree when reinstatement would happen, particularly where further visits are expected, so it is not done and then undone.

Making good carried out before the last visit is work performed twice or abandoned, and the sequence is easy to agree.

Photograph the same positions afterwards and compare them directly with the record taken beforehand, rather than relying on what anybody recollects.

The matched pair is what turns a disagreement about the ground into a straightforward comparison.

Keep watching the route over the following seasons and note anything that appears later on, particularly after a prolonged spell of wet weather.

Some effects of a vehicle on soft ground are not visible immediately and only show once the ground has been through a wet period.

Add a note to your property record saying what used this ground, when it happened, and what was observed in the months afterwards.

That note is what explains a pattern in the ground to somebody looking at it years later with no other information.
