What is scoria nz?
25 to 7mm graded scoria is a lightweight but very strong aggregate which is perfect for use in draining gardens and lawns and in the Auckland region as a popular choice of backfill behind retaining walls and perforated pipes.
How do I use scoria in my garden?
To work out the volume in litres,use the following formula: (length of garden bed (cm) x width of garden bed (cm) x 20cm)/1000, so for example a 2mx1m garden bed will take (200*100*20)/1000 = 400L of scoria. or 0.4 cubic metres.
Can scoria be used for drainage?
Also used by many landscapers and home gardeners to improve drainage. Ideal use: base of tree pits, raised garden beds, planters and large pots. Other info: be advised that as this is a natural product, slight colour variations may occur from time to time.
Why is scoria used for drainage?
The drainage aggregate called Scoria is a type of igneous rock formed under pressure during the formation of volcanic cones. It is therefore extremely hard and durable yet very porous, so it drains water from surface soils extremely well.
How is scoria different from pumice?
Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls, and hence is denser. The difference is probably the result of lower magma viscosity, allowing rapid volatile diffusion, bubble growth, coalescence, and bursting.
Is scoria the same as pumice?
Scoria is an extremely vesicular basaltic lava with very small (< 1mm) vesicles. Landscapers know this rock as lava rock. Pumice is a froth of felsic volcanic glass. It is rock foam with so much air in its structure that it often floats on water.
What can you do with scoria?
It is somewhat porous, has a high surface area and strength for its weight, and often has striking colours. Consequently, it is often used in landscaping and drainage works. It is also commonly used in gas barbecue grills. Scoria can be used for high-temperature insulation.
How do you clean scoria?
After practice, lay the mat flat to air dry. If there is dirt or body oils, wipe the mat down with a wet soft cloth with warm water. Every once in a while you can use mild soap with water before stains settle. And please DO NOT put your Scoria yoga mat in the washing machine.

Can you compact scoria?
Do not use scoria material for bedding or joint material or basecourse. Do not compact paving materials – this reduces drainage capacity.
What do scoria and pumice have in common?
A vesicular igneous rock that is very similar to scoria is pumice. Scoria forms from basaltic magmas, while pumice forms from rhyolitic magmas – which usually contain more gas. Pumice has a much higher concentration of trapped bubbles – so many that the walls between them are very thin.
