Artificial Lawn Problem

Hi everyone, this is my first post. I'm not a gardener or landscaper, but I have 3/4 acre, with about 1000m2 of newly laid artificial grass.

I'm very concerned about the finished job. There are 2 area of lawn. A flat area of around 350m2, and an area of 650m2 on a slope.

The grass is a high quality product called Perfection from Hitech. It is  40mm in length.

With the areas in question there are 7 or 8 joins in each area. Almost all are 4m wide. There are no cross joins.

I have a few concerns.

The first is the joins, which are still visible after 6 weeks.

Second, there are lines going across some of the widths, that LOOK like cross joins, athough they are not.

Next is the grass just lies flat, even with just the weight of a ball. It does not bounce back.

There are lumps and bumps here and there, where either the ground was not levelled properly, or as I have noticed in others, sand has spilled and become compacted.

Lastly, we had a very heavy storm about 17 days ago. An overflow from our drains backed up onto the garden. There was a small amount of sewage involved, mostly underneath the grass. A landslip occurred, causing a gash in the sand underneath of around 6 inches in width, running the full length of one of the strips approx 10 yards. The contractor was told before hand about the position of the overflow. I told them not to fit up to it. They ignored this and fitted over it. It looked fine. The pipe had overflowed once before about 7 years ago, due to sanitary products being flushed down a loo in a secondary building which has a saniflo installed. The problem this time was just sheer volume of water that the drains couldn't cope with.

I bought the grass direct, as I was able to negotiate a better price than the contractor, the contractor was happy with that. He has been paid 85% of his fee even although I was only contracted to pay 50% after groundwork, and 50% on completion. He subcontracted the grass fitting to a guy who will not return calls. Thankfully he hasn't paid him.

My main argument with the contractor is that the joins are very visible. He says they will fade. I'm not so sure. No power brushes were used on the grass before or after the install. He used half of the sand recommended by the manufacturer. He added some more to the flat area and then power brushed it, but the improvement is minimal. I  myself have now bought a power brush, but will not use it until this guy comes back and says the job is complete.

The lines that look like cross joins; until I'm satisfied that the job has been installed correctly, I can't really say if there is an issue with manufacturing. I suspect there is still not enough sand on the job, but I don't know.

I'm trying to learn as much as possible about installing this product, but there are various ideas.


1. Should I see joins? If so, how noticeable? Will they go away? If so, when?

2. Should the grass spring back immediately from the weight of a ball, or a dogs toy, or a garden hose?

3. Does anyone know of anyone in the west of scotland who could come and give me a straight forward unbiased opinion on the standard of the job, and of the grass?

Your help would be so appreciated, and help me take this forward.

The contractor is a proper landscape gardener, recommended by my previous gardener.

Thank you

        • Colin, apologies for being so terse. It was late, and frustration creeps in. Only to say that the contractor is still seeing this through. His subcontractor, the installer, however is not. He will be back this morning to sort the landslip issue, and we will discuss the next move.

      • Some of the grass samples I showed customers last year and the year before the most expensive was £48 per square metre. It really looks like the real thing as the material had also some brown beige and two colours of green running through it. When you put it next to good quality real lawn one could hardly see a difference. It also seemed to stand up well as it had a thicker under pile which pushes the green pile up. It is quite soft to the touch. I looked in my storage but must have left it somewhere with one of my clients.
        If I remember correctly all the manufacturers or uk resellers only give 5 years guarantee on the material itself.

        To be honest this year I have only seen two artificial lawn people about in my area. Artificial Lawns and Planet Lawns.

        Yes, most if not all lawn firms will sell their materials directly to the end user so they can fit it themselves or someone they hired.

        If it makes you feel any better I spent nearly £10K last year to get 16 solar panels fitted. I am now trying to find a roofer willing to fit the edges of the panels with pigeon guard as the birds are sitting underneath breeding and making a flipping mess and noise. The solar company is washing their hands on the matter. They should have told me that could be an issue and I would have paid a bit more to get this done. Because it's a 3 story town house I cannot find anyone, but I think it's because it's a small job and no interest.

          re roof, buy a cat, or a gun.

          • That looks similar to the stuff I was showing to my customers last year and the year before. They just had different names. They even sell two types of underlay similar to the ones I was sent.

            Don't do guns and allergic to cats. But local pigeons seem to like my panels more as they get nice and cosy under them all day due to light.

            To be honest, you know the saying: A crow will not pick out the eye of another crow.

            I have only been once to Scotland (Edinburgh) so I would have thought that artificial grass could be more popular up north with more installers due to grass growing conditions. Like someone said it was quite popular the last couple of years. This year I have not even seen the DIY chains carry any at least in my area in SE London. Nor have I been spammed by emails, mail or text from artificial grass companies. Have done a quick google but cannot find the "posh" grass company. I think they were located in the Midlands. Like I said it was a couple of years ago. This also means prices could have dropped for the same type of lawn over the years.
            • Just noticed they give 15 years guarantee. That is quite impressive. Hopefully that company is still about in 15 years. My cynical self would think not.

            Unless the cat has a IRATA ticket and full harness, and the solar panels are bulletproof, I think you'd be on a hiding to nothing here... ;-)

            • I found a pest company that pigeon proofed a distant neighbors solar panels. They are doing mine on Thursday. Thank goodness. Its getting pretty bad now as too many of those flying rats under my panels. They are having a party, but On Thursday I am having the last laugh!

                A local hawk enthusiast would have been a temporary solution.

    We supply and fit artificial grass you shouldn't be able to spot the join.
