A stylish oversized high quality slate from Brazil, with a smooth lightly riven surface which imparts a luxurious contemporary look. This naturally clean splitting slate has a gentle riven surface texture and is hand selected for colour consistency. Three large sizes can be laid in a random or regular pattern for an ultra modern look.

  • Natural Slate inevitably shows variation in colour so viewing the actual samples is always recommended
  • Because these are natural materials, the size and thickness may vary. This can normally be allowed for when laying
  • Slate, like all natural stone can be prone to surface scratching during installation. This will weather over a period of time
  • Natural Slate should be laid on a full mortar bed.
  • Install smooth side down
  • Natural Slate paving joints are recommended 8-15mm wide and fully pointed with mortar or using brush-in Weatherpoint 365
  • Paving should not be butt jointed
  • If used indoors an appropriate water-based sealant is recommended
  • This paving is ideal for jointing with Marshalls all weather, WeatherPoint 365 Jointing Compound or Marshalls Exterior Jointing Grout

Marshalls Order Select

When designing your garden or driveway there may be times when you do not need full packs. The majority of Marshalls landscape materials are available to order in split pack quantities using their Marshalls Order Select Service.

The Marshalls Order Select carries a premium charge, and will be charged separately to any full packs ordered through this site. Where possible, it might be more economical to adjust requirements to the full packs.

To calculate the cost:

  • UNIT COST: Divide the pack cost by the number of units per pack
  • SPLIT PACK COST: Multiply the unit cost by the number you require
  • SERVICE COSTS: Marshalls Order Select Fee* = £105 + £15 admin fee
  • TOTAL COST = Materials + £105 (all costs are inclusive of VAT and delivery)

Marshalls Order Select fee* is charged per ton of material required. So you can split a variety of packs in different sizes and the Marshalls Order Select and Admin fees are applied to the whole order relating to the split packs, not by the individual split pack.

Please note:

  1. If you are extending a project, it will be likely that batch numbers will be different from your original order and colour may vary.
  2. If ordering full packs and split packs every effort will be taken to ensure batch numbers match for consistency.
  3. If ordering from a Project Pack, the maximum number cannot exceed the amount of that single size contained within the pack.
  4. For driveway and walling products, it is best to order quarter pack, half pack or three quarter packs. The Marshalls Order Select and Admin fee remains the same £105
  5. Once materials have been delivered and in line with your cancelation rights, split packs are non-refundable

If you have worked out the cost is viable, please email with your material requirements, your name, delivery address, contact email and telephone number. A manual order will be created and emailed back to you to complete your transaction securely online. This service takes approximately 5 working days to deliver from receipt of your order.

Minimum order delivery cost

The minimum order value to qualify for free delivery is £900 (excluding any Marshalls Order Select materials which are charged separately). Materials will be delivered by flat bed truck with crane offload facility, or curtain sider, using a pallet lifter. Please advise of any access restrictions when placing your order.
