Mixed pile direction
Grass fibres lean one way. Join two rolls leaning in different directions and the colour and sheen change as if a line were drawn between them, even when both rolls come from one batch.
The giveaway of a weak artificial grass job is a visible seam or a lifting edge. This page explains how rolls are joined so the seam blends into the lawn, and how edges are fixed along walls, paths and planters in Riyadh’s heat. When you are ready, we arrange a free inspection and quote by phone or WhatsApp.


Installing artificial grass is more than unrolling and cutting. Seams and edges decide how good the job looks. For the full picture, read artificial grass installation in Riyadh.
Grass fibres lean one way. Join two rolls leaning in different directions and the colour and sheen change as if a line were drawn between them, even when both rolls come from one batch.
The roll edge carries a strip with no fibres. If it is not trimmed before joining, a bare gap shows between the two rolls.
Too little adhesive, or letting it skin over before pressing, opens the seam with heat and foot traffic. Tape, adhesive and backing must work together.
A seam in the middle of a path or beside a door takes the most pressure. We plan the layout to keep seams away from these lines where possible.
When edges are not pinned or held by a solid border, they lift over time and ripple near walls.
Any hollow or wave in the base shows under the seam, so preparation comes first, as in grass base and drainage.
Before cutting anything we sketch a roll layout: where the first roll starts, which way the pile leans and where the seams will fall. We aim for as few seams as possible, away from main walking paths and play zones, with the pile leaning toward the most visible side of the garden.
Artificial grass reflects light differently depending on how the fibres lean. All rolls are laid in the same direction, and a roll that arrives reversed is turned before cutting. This single step prevents many of the visible seams that garden owners complain about.
We trim the fibre-free selvedge from both roll edges so the first stitch row stays intact, then bring the rolls together until the fibres touch without overlapping or leaving a gap. If a visible gap remains after cutting we redo the cut rather than let adhesive cover it.
Seaming tape goes under both edges, then an adhesive suited to the backing is spread and the rolls are pressed down in sequence, taking care that no fibres are trapped in the glue. In Riyadh we watch the temperature because it changes setting time, and we work in short sections so the adhesive does not skin over before pressing.
We follow the adhesive manufacturer’s waiting and loading times and do not quote fixed times here, because they differ between products.
Along walls and fences the grass is fixed with suitable nails or pins at planned spacing, with the heads hidden among the fibres. In open gardens we use a solid border of concrete, timber or plastic edging that stops creep and keeps the shape along paths and planters.
For roofs and balconies see also rooftop artificial grass and balconies for what is specific to those places.
Gardens with curved paths and round planters need more careful cutting, so we first cut a rough template and trim the final edge after the grass is laid, so that it follows the solid border exactly. In inside and outside corners we avoid pulling the grass tight, which can make it lift later.
Around trees and posts we cut circular openings and fix the edges so bare backing never shows.
Once the seam has set we brush the fibres up to blend the join, remove fibres stuck in adhesive and check the edges again. Where the lawn will be topped with sand or infill, it is added only after every seam is confirmed secure.
We suggest checking seams and edges after the first weeks of use and after the first long hot spell, because heat and traffic reveal any weakness. If you see a seam opening or an edge lifting, send us a photo on WhatsApp so we can advise before it spreads.
Regular care such as brushing and removing leaves keeps the surface looking good; we collected it in artificial grass maintenance.

We set a solid edge along paths and planters so the grass does not creep and the garden lines stay sharp.

We allow for parapets, drainage and heat and fix edges to suit tiles or concrete.

Lots of running here, so we keep seams away from play zones and fix the edges firmly.
Measure the site and draw the roll layout, pile direction and seam positions.
Level and compact the sub-base and set falls for drainage before any roll is laid.
Trim the bare selvedge and bring the two rolls together so the fibres touch without a gap.
Lay tape and a suitable adhesive, then press down gradually and check the seam.
Pin the edges or hold them with a solid border, then brush the fibres and clean up.
| Type | Where it suits | Note |
|---|---|---|
| Concrete edge | Gardens and paved paths | Firm and traffic-proof but needs planning ahead |
| Timber edge | Planters and garden borders | Looks good but needs treating against moisture |
| Plastic edging | Flexible borders and curved gardens | Easy to shape for curved outlines |
| Direct pinning at the wall | Fences and entrances | Fine if the base is solid and takes pins |
The edge choice depends on the base and garden shape. We decide after the inspection rather than force one type on every site.
Backing quality, density and pile height all affect how well a seam can be hidden. Denser grass hides the join better, while short or thin grass shows any difference more.
Learn about heights and quality in the grass heights guide and quality, density and yarn before you choose.
When you ask for a quote, tell us if there are trees, paths or planters; these add cuts and waste and change the quantity needed.

Nails fix but do not hide or bond, and can leave an opening that lifts.
High heat speeds up setting and makes adjusting harder.
Edge rippling starts at corners if they are not fixed well.
A slight colour difference can show at the seam.
Enter the garden length and width to get the area in square metres plus a waste allowance for cuts at seams and edges, then send the result on WhatsApp.
With correct pile direction, careful trimming and good bonding the seam is usually hard to notice, but grass type, density and base quality all affect the result.
It depends on roll width, area and site shape. We draw the layout after measuring to keep seams as few as possible.
The seam itself relies on tape and adhesive; pins are mainly used to fix edges. Each does a different job.
Heat affects expansion and adhesive setting time, so we choose a suitable product, work in sections and pay attention to the time of day.
It can if the edges are not well fixed or held by a solid border. Proper fixing reduces the risk a lot.
In most cases the damaged part can be opened, cleaned and re-bonded with new tape. An inspection decides the method.
Small areas may work, but larger ones need planning and tools. See the artificial grass installation page for details.
