Buying Guide for Artificial Grass

EvergreensUK-events-header

Artificial grass has come a long way since it was first introduced back in the 1970s. Over the last 10 years in particular, we have seen amazing advances in the look and feel of synthetic materials for landscaping use. We have compiled a short, helpful guide to assist you in selecting the right product for your project. If you’re still unsure, give us a call.

Artificial lawns have been a modern revolution in the UK and the market is still in its growth period. There are many different products in the marketplace, but many are simply imported and are not designed specifically for the UK market, thus they can often be too dark or appear washed out.

To achieve the most natural looking lawn the trick is to select a product that matches your current lawn. The easiest way to decide which colour suits your environment is to place your samples on real turf, stand back and decide which matches or simply which colour you prefer.

Our most popular products include Lazy Signature and Wonder Yarn, they combine the fresh green look of British grass with a dynamic dual colour thatch layer adding greater depth to the look of your lawn.

Our products are produced on 2m and 4m widths, so when measuring your lawn or roof terrace, always think about the wastage factors. For example, if you are in the designing stages, try to keep one of the dimensions an even number to limit any wastage factor.

All of our staff have been trained to assist you in this area. If you can send a plan or sketch of the area with measurements taken from both axis at 1m intervals, then we can minimise any wastage factor for you.

For further information please see our measuring guide.

When you are installing a lawn, it is essential to keep all of the rolls running in the same direction. There is a temptation to turn sections to avoid wastage factors, but if the direction is changed this ultimately compromises the finish and is never recommended.

In general terms, test the look and feel of the product. Ensure that the product has a consistent colour and the tufts are well stitched and product is evenly backed.

*Please note in the sample packs, the products may appear to be malting, however this is not the product failing, it is simply where the sample has been cut on an industrial press machine and the tufts at the perimeters have been penetrated, hence they fall out. This will not happen with any product once fitted.

Texture is also a factor when choosing your synthetic surface. All of our landscaping products use the softest polyethylene yarn and this is important in domestic gardens where children are using the lawn, where you want to choose the softest surface possible. That said, polyethylene and polypropylene mixed surfaces along with polyamide surfaces are commonly installed in school areas and are perfectly safe for children and all offer fantastic durability combined with the ideal pile height and density attributes.

For lawns, a minimum pile height of 25mm is recommended. Anything shorter and this can sacrifice the natural look you are striving for. We offer a number of landscaping products between 20-40mm, with a 37mm product like our Lazy Signature offering the softest and most lush looking finish.

For terraces, a dense product should be selected, between 14mm – 35mm is generally recommended. If you are using the roof space as a lawn then a product such as our Wonder Yarn 26mm or our Lazy Signature is ideal.

If you are using furniture on the space such as tables and chairs, then a shorter, denser product like our Wonder Grass range may offer better suitability.

This refers to the amount of yarn, the thickness of the yarn and the number of stitches in the product. Generally the heavier the product the more yarn content, hence the product will be more expensive. However, it also depends on the shape of the yarn and colour of the yarn(s) in the product. A shaped yarn and more vibrant coloured yarn is more expensive to produce, so if two products are similar in spec (dtex, density, pile height etc), the colour could be the difference. As a company, we only supply the highest-grade products and only use the highest-grade yarns.

For high-traffic areas, the density of the product should be high, as this will perform better over a longer period of time. More density is also beneficial for swimming pool surrounds, walkways, boat decks, putting greens, patios, and play areas. On less-dense products, the longevity and performance of the product is improved with a sand infill. The sand infill varies between 5 kg p/sqm to 25 kg p/sq depending on the specification of the product.

Evergreens installation teams have been supplying and installing artificial grass for over 25 years, and during this time we have seen remarkable advances in the production methods and yarns used, making them a highly natural looking and durable alternative to real grass.

Our experience has allowed us to test and develop installation techniques to ensure your garden remains hard-wearing and trouble-free. A number of newcomers to the industry try to discredit sand infill products, often using misleading statements and images of synthetic grass heavily laden with sand.

We recommend sand infill systems for the following reasons;

  • Large areas of non-sand-filled systems expand with heat during hot weather, creating sagging and ripples. Sand infill stabilizes the system without needing to install a perimeter frame to fix the grass. Frameworks to which the grass is fixed pose problems when the newly installed ground work settles, leaving unsightly ridges around the perimeter. Sand-filled systems allow the surface to settle with the natural ground movement.
  • Some non-sand-fill systems can encounter problems with static, causing an electric shock. Clearly not something you would want to experience when children are using the area.
  • Non-sand-filled areas will not lay flat in contoured areas unlike sand-filled surfaces due to the weight holding it in place.
  • The sand does not transfer onto your clothes and is not visible as stated by some companies.
  • Some longer-piled surfaces without sand infill will have very little fire resistance.
  • Non-sand-filled surfaces are at greater risk of theft, as cutting the product is simple. Sand infill systems act as a deterrent as it makes it difficult to cut through the product, blunting knife blades instantly.
  • As stated by some, sand infill systems do not necessarily mean less density or a lower grade of product. We will only use high-grade AND high-density surfaces.
  • Both non-sand and sand infill surfaces will encounter similar germination of airborne particles. This is simply removed by using a weed suppressor or plucking out weed growth.
  • Note to dog owners – non-sand-filled surfaces are susceptible to damage due to the base of the grass being clawed at by your dogs when running around.

On certain areas where the grass can be fixed 100% i.e. around pool areas using adhesive, a sand infill is not always needed.

Generally, there is no reason not to sand-fill the surface. The only benefit to no sand infill is to the installer, as he does not have the issue of transporting the heavy sand, enabling the installer to cut out a timely process to gain on margins and appear to install at a cheaper price than competitors who sand-fill.

Full rolls of artificial grass are produced in 2m and 4m widths and usually made to either 25m or 30m lengths. Full rolls are very heavy (300 kg is average for a high-quality 4m full roll), so unless you require full rolls for your project, it is advised to take advantage of our cut roll service to make the rolls more manageable to handle.

Lawn Installations

Generally artificial lawns do not require shock pad to be installed prior to the surface being installed. Shock pad may be used if you plan to install play equipment on the lawn.

Roof Installations

Depending on the original roof surface, an underlay is generally recommended with a roof terrace, as this helps to protect the surface and allow free drainage. We have two products designed for this; Lazy Pad and Lazy Foam. Using an underlay enables you to avoid directly adhering the material to the roof system to secure the product in position.

When installing on a roof, balcony, or such like, you must consider the weight-bearing factors. Please call to speak with one of our technical team to discuss any specific areas you are unsure of.

Play Area Installations.

Nursery and school play areas with play equipment will require an underlay that conforms to critical fall heights. Our Lazy Pad product offers a fall height of 1.3m when used with our range. The foam shockpad will only need to be installed around the equipment and not necessarily the whole area. A foam underlay is rarely needed if there is no play equipment as it adds an unnecessary cost to the project, as using a polyethylene surface (see texture section above) provides a soft surface ideal for children.
