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.
