A good sod installation begins before the rolls arrive. The ground has to be cleared of unwanted material, graded to the right slopes, and prepared to give the roots even contact. The sod then has to be laid quickly, with tight, staggered seams, and kept moist while it establishes.
The immediate green gives the impression the work is finished. In reality, the first weeks are about joining two living things: the roots of the slab and the soil of the property.
Before delivery: preparing the ground
Remove what will work against the new lawn
Old vegetation, large stones, debris, unwanted roots and material incompatible with a lawn all have to be removed as needed. Laying rolls straight onto an old lawn or a surface full of residue creates uneven contact and corrects no fault in the levels.
Correct the levels
Grading creates an even surface and directs water. It has to account for the house, the patios, the walkways, the walls, the edges and the neighbouring properties. A lawn does not need to be perfectly horizontal; it needs a coherent slope with no hollows that hold water.
If the site has a recurring problem, stormwater management has to be settled before the surface is covered.
Prepare the soil layer
Roots have to be able to meet soil that suits them, even enough and free of unevenly compacted areas. How much topsoil is needed, and of what quality, depends on the state of the site. Amendments and fertiliser should not be applied automatically; they have to match the soil, the product and the recommendations adopted.
Firm the surface without closing it up
The final soil has to be firm enough that footsteps and rolls do not create large hollows, while keeping a surface that favours root contact. Areas that are too loose or too hard produce an uneven result.
Check the watering before laying
The whole surface has to be reachable. Corners, edges and areas exposed to wind sometimes dry faster. Testing hoses, sprinklers or irrigation zones before delivery avoids discovering an unreachable area once the sod is already down.
Delivery and handling
Sod is perishable. The rolls should be delivered as close as possible to the moment of laying and protected from a long wait, especially in hot weather. The team organises the site to limit unnecessary movement and get the product down quickly.
The ground can be lightly moistened before laying if it is dry, without becoming muddy. A waterlogged surface marks easily and makes holding the levels harder.
How to lay the rolls correctly
1. Start from a straight line
An edge, a walkway or a stable reference line helps keep the alignment. Rolls are unrolled without being stretched, since a slab under tension can shrink back and open the seams.
2. Butt the edges tight, with no overlap
Slabs have to touch closely. They should neither overlap nor leave a gap. An overlap creates a raised ridge that dries out and roots poorly; a gap exposes the edges and encourages them to dry.
3. Stagger the seams
The ends are set in a staggered pattern, like the joints in masonry. A long transverse line running across the whole lawn should be avoided.
4. Make clean cuts
Around a curve, a tree, a drain or an edge, slabs are cut precisely. Small isolated strips dry faster; it is better to organise the cuts so the pieces stay reasonably wide.
5. Adapt the laying to slopes
On a slope, the orientation of the rolls and how they are held have to prevent movement while rooting. Depending on the gradient and the conditions, temporary anchoring may be necessary. Runoff has to be controlled before laying.
6. Ensure contact with the soil
Once in place, a suitable pass helps the roots and the soil meet and reduces air pockets. That operation is not there to correct deficient grading or to crush waterlogged soil.
7. Water without delay
Watering starts during or immediately after laying, particularly on a large surface or in hot, windy weather. It has to moisten the sod and the soil layer beneath it evenly.
Watering while the lawn roots
There is no universal schedule valid for every property. Frequency depends on temperature, wind, shade, rainfall, soil and the watering system.
At the start, the aim is even moisture without letting the slabs dry out or turning the ground into permanently saturated soil. Edges and exposed areas need closer watching.
As the roots establish into the soil, watering can become less frequent and deeper depending on conditions. Lifting a corner of a slab shows whether the moisture is genuinely reaching the soil; a wet surface does not guarantee the root zone is getting enough.
If rain is already supplying the moisture needed, the watering has to be adjusted. Continuing mechanically despite saturated soil can be as harmful as letting the sod dry.
How to check rooting
Gently lift a corner in a few places. At first the slab lifts easily. Over time resistance develops as roots penetrate the soil. That observation is more reliable than a fixed number of days, since establishment conditions vary.
Colour, how the seams are holding and the resistance to lifting together give a better reading. An area can root more slowly if it gets less sun, more water or uneven watering.
When can traffic and mowing resume?
Traffic should stay limited while the lawn roots. Walking often on damp ground can create depressions, shift the slabs and work against contact with the soil.
The first mow happens once the sod is rooted enough not to be lifted by the equipment and the grass has reached an appropriate height. The blade should be sharp, and the cut should not remove an excessive share of the height at once.
The exact moment depends on growth, not on a universal calendar. Mowing a waterlogged surface should also be avoided.
Fertiliser: avoid doing it by reflex
Fertiliser may be indicated depending on the soil preparation, the product, the season and the supplier's recommendations. Adding fertiliser without knowing the need does not guarantee better rooting and can complicate maintenance.
If a specific protocol comes with the project, it should take precedence over general advice. Longer term, maintenance should suit the actual state of the lawn and the soil.
Common problems after laying
Edges yellowing or drying
Open seams, small cuts, wind and incomplete watering can all dry the edges. Contact should be checked, gaps closed properly where possible, and the watering adjusted.
A soft or waterlogged area
A low point, saturated soil or excessive watering may be the cause. Whether the problem comes from maintenance or drainage has to be determined before simply adding more soil or water.
Slabs that lift easily
The sod may lack moisture, contact with the soil, or time to establish. Unsuitable soil, or a layer between the slab and the ground, can also slow the roots.
Visible lines
Seams can stay visible at first. They become more of a problem if they are open, overlapped or dried out. Butted laying and even watering limit those marks.
Uneven colour
Moisture, shade, soil, temperature and contact can vary from one area to another. Conditions should be compared before concluding there is a product problem or adding a treatment.
Why coordinated installation matters
Terrassement XP connects sod installation to site preparation, grading, drainage and the neighbouring finishes. That coordination is particularly useful when a new lawn completes a patio, a driveway, a pool or a landscape project carried out from start to finish.

Frequently asked questions about laying sod
Should edges be overlapped to avoid gaps?
No. Edges have to be placed firmly against one another, with neither gap nor overlap. End seams should be staggered.
Does it need watering every day?
Water according to the actual moisture, the weather, the soil and the exposure. A fixed daily instruction can be insufficient during a hot spell or excessive after heavy rain. The aim is even moisture while rooting, without constant saturation.
How long before walking on the lawn?
Traffic should be limited until the slabs resist lifting gently and the ground no longer deforms underfoot. The delay varies with conditions.
When should the first mow happen?
Once the sod has rooted, the grass has reached an appropriate mowing height and the ground is not waterlogged. Avoid cutting too short, and use equipment that will not lift the slabs.
Does laying sod fix a yard where water collects?
No. Sod can mask the fault for a while, but the water will return if the grading or the drainage is not corrected before laying.
Success is decided before and after the laying
Careful installation produces an even surface from the outset. Soil preparation, speed of laying and care during rooting then determine whether that visual result becomes a genuinely established lawn.
