20mm Plum Slate – 20kg Weatherproof Bag

£4.49 ex VAT

Product Overview
20mm Plum Slate – 20kg Weatherproof Bag contains decorative natural slate chippings for adding colour and texture to paths, borders, rockeries and landscaped areas. The predominantly flat, angular pieces settle together to create a neat surface that is comfortable for pedestrian use. Plum and purple tones appear softer when dry and become deeper and more vivid after rainfall or washing, providing a distinctive alternative to conventional gravel.

Plum slate is a durable, low-maintenance ground covering that will not rot or decompose like bark mulch. When installed over a suitable permeable weed control membrane, it can help reduce weed growth while still allowing water to reach the ground beneath. The manageable 20kg bag is convenient for smaller garden projects, restricted-access locations and topping up existing slate. It may also be used around decorative water features, although suitability for ponds containing fish should be confirmed for the supplied material before installation. Colour, shape and precise grading will naturally vary.

PLEASE NOTE:
!!! During periods of high demand or temporary supply shortages, an equivalent brand may be supplied. Any substitute will be of comparable quality and suitable for the same applications. !!!

Frequently Asked Questions

Toggle

Q. What colour is plum slate?
A. It contains a natural mixture of plum, purple and grey tones. The slate generally appears paler when dry and considerably richer when wet.

Q. Should a weed control membrane be installed underneath?
A. A suitable permeable weed control membrane is recommended beneath borders and decorative areas to reduce weed growth while allowing water to drain through.

Q. Can this slate be used in a fish pond?
A. Plum slate is commonly used around water features, but fish safety should be confirmed for the supplied material. Any approved slate should be washed thoroughly before being introduced to a pond.

Q. How much area will one 20kg bag cover?
A. As a general guide, one bag should cover approximately 0.3m² at a depth of 40mm. Coverage varies according to the surface, grading and finished depth.

Q. Will every bag look identical?
A. No. Slate is a natural product, so variations in colour, thickness, shape and particle size should be expected between bags and deliveries.
