A green roof is a unique environment that calls for a unique growing medium. With almost 2 decades of growing sedum and wildflower blankets for use on extensive green roofs, Turfonline have perfected a growing medium that meets the needs of both the building and the plants. Our specially blended extensive green roof substrate is tested to the German FLL guidelines (2018) and it provides the perfect base for establishing a green roof.

An extensive green roof needs to retain moisture to support the plants, whilst also remaining lightweight. Turfonline green roof substrate is made from recycled materials giving a low density, low nutrient base with optimum water retention properties.

The use of recycled crushed brick provides the most effective media for extensive roof systems, due to its ability to retain moisture whilst also remaining lightweight.

Available in either Bulk Bags (0.6m³) or 25 Litre bags for easy handling

Green Roof Substrate – Key Points

  • Relatively light weight when compared to topsoil and compost. Dry weight approx 0.95kg/l, saturated weight approx 1.3kg/l.
  • Free draining – creates the ideal conditions for popular green roof plant species
  • Less water retention = less loading on the structure of the building
  • Larger particles 0-14mm – will not wash away in heavy rainfall
  • Low percentage of organic matter – will not oxidise over time and need replenishing
  • Open structure – not easily compacted
  • FLL approved for use on living roofs
  • Peat Free

Green Roof Substrate – Composition

  • 70% Mineral Material
  • 30% 10mm PAS100 complaint green compost

Each bulk bag covers 24m² to a depth of 25mm

Each 25L bag will cover an area of 1m² to a depth of 25mm

Can you take my pallet away? Unfortunately not - please can you reuse or recycle.
  • For palletised goods our standard service will be delivered between 8am - 8pm. We are requested not to contact the delivery depot for ETAs until the afternoon. Therefore if your delivery is not with you by around 2-3pm please get in touch and we can find out what time it should be with you.
  • If you selected a pre 11am delivery, this should be with you from 8am - 11am. If in the unlikely event that your order is not with you within this time frame, please contact us.
  • If you selected a pre 2pm delivery, this should be with you from 8am - 2pm. If in the unlikely event that your order is not with you within this time frame, please contact us.
  • Our Saturday deliveries are normally delivered between the hours of 8am - 2pm. During busy times this may be extended but should be with you before 4pm.
  • If your item is arriving via a parcel carrier you should receive a text message from the carrier with an ETA.
  • With all of the services mentioned above, we are unable to provide an ETA until the day of delivery.
 

For all palletised goods, during the checkout process you can select your required delivery date along with any timed upgrades. For parcels, these are despatched on the next business day.

 
Bulky items like Turf, Topsoil and Wildflower Turf can be delivered Tuesday to Friday. We can also offer deliveries on Saturdays for an additional charge. For orders placed before 10am we can even offer a next day delivery. Please select your preferred delivery date from the available dates during the checkout process. This is dependent on the delivery postcode.  
We offer kerbside delivery, so pallets are usually left on the road to the front of your property. We can occasionally deliver to your driveway if it is flat, level and a solid surface, and if the kerb is dropped enough for a pallet truck to roll over it whilst fully loaded.

Your Delivery

Turf Online aims to give its customers the best possible experience by delivering the best quality products for sale in the UK. Therefore, all our perishable products are harvested fresh to order the day before delivery, and we even accept orders for next-day delivery!

Delivery charges and services vary by different types of turf and delivery location. Charges are confirmed at checkout before payment. If your order includes grass turf, topsoil, Wildflower Turf or Sedum mats, you can choose your delivery day. You should arrange for live products to be delivered on the day you will lay them. Reducing the amount of time the product is stored means significantly less potential nuisance when it comes to installation; certain issues will not have had a chance to rise. All other products are delivered within 5 working days (or usually sooner!).

How Is Your Product Delivered?

We recommend that you only make arrangements for tradespeople to carry out work on your behalf after your turf or other products have been delivered.

PLEASE NOTE: Turf, Wildflower Turf, Sedum Mats and bulk Bag products are delivered on a pallet and can only be delivered to the kerbside. 

Most of our products for sale in the UK will be delivered by being transported by a pallet courier that primarily uses 18-tonne rigid trucks that are built for reaching the majority of UK addresses. However, it is possible that your delivery could be made on a larger vehicle. If access or other restrictions prevent vehicles above a certain size reaching your address, or there are other offloading or parking restrictions which could affect the delivery, let us know in the delivery notes section of checkout so that special delivery arrangements can be made. Please make sure you double check the delivery postcode and address carefully as after your order has been shipped, it is likely we will not be able to make any amendments to your order or address.

Delivery is unloaded using a manual pallet trolley which is lowered to the road by the tail lift on the truck. Unfortunately, we do not offer Hiab (truck-mounted crane) deliveries. To offload the pallet, the surface must be flat and level. Since Turf, Wildflower Turf, Sedum and topsoil can be heavy, and the pallet trolley pulled by the driver has small wheels, pallets cannot be delivered onto soil, grass or gravel – a tarmac or paved surface is required.

Kerbside delivery means that our products for sale in the UK is delivered as close as possible to the delivery address you provide. Our helpful drivers will do their best to place your delivery where you wish, such as a driveway, but this is at their discretion. If your delivery address is hard to find or the property is a new build, consider using what3words to pinpoint your delivery location. More information on what3words can be found in our Help Centre.

What Issues Could Arise With Delivery?

If your product delivery cannot be made due to a reason you failed to make us aware of, the full cost of distribution and products will still be charged to you. We are proud that most of our turf deliveries arrive on time. Sometimes, circumstances beyond our control (extreme weather, road accidents, vehicle breakdowns or IT failures) can delay delivery, but we will make every effort to keep you updated in such an event.
