Lava-Lite Soil-Restore+ - Volcanic Rock Conditioner for Compacted Soil
Best for: gardeners dealing with heavy clay or compacted soil who want a permanent structural fix rather than a yearly dig-over.
Our thoughts
Digging compacted clay every year gets old fast, and Soil-Restore+ is a proper long-term answer to that rather than a quick fix that washes away after one season. It's a mineral, not an organic mulch, so it doesn't break down - dig it in once and it keeps working.
Lava-Lite Soil-Restore+ is a 100% natural, pH-neutral volcanic mineral soil conditioner. Dug into borders or heavy clay soil, it introduces thousands of tiny air pockets that improve aeration and drainage, breaking up the compaction that causes clay to clump and become difficult to plant into. Because it's a durable mineral rather than an organic material like bark or compost, it doesn't decompose - it's a one-time structural upgrade rather than something you need to top up every year.
In pots, it's used differently: filling 15-25% of the pot's capacity with Soil-Restore+ at the base improves drainage and root aeration, helping prevent overwatering issues while still letting roots draw up moisture as needed.
How it compares
Most soil conditioners are organic and temporary; Soil-Restore+ is mineral and permanent.
- Unlike garden gypsum or organic matter such as compost or bark, it doesn't break down over time, so the structural improvement to clay soil is lasting rather than seasonal
- A lower-cost, UK-made alternative to imported expanded clay pebbles for the same pot-drainage job
- Works differently to biological soil conditioners like mycorrhizal inoculants - this fixes physical structure, not biology, so the two can be used together rather than as alternatives
If you're tired of the same clay compaction coming back every year, this is the product that actually stops it recurring.
Usage guidance
Border and clay soil use
Dig Soil-Restore+ into the top layer of clay or compacted soil to introduce permanent air pockets and improve drainage.
Pot use
Fill 15-25% of the pot's total capacity with Soil-Restore+ at the base before adding your growing medium, to improve root-zone aeration and drainage.
Reapplication
Because it's a mineral that doesn't decompose, it's a one-off addition rather than something that needs annual reapplication.

Our take
Soil-Restore+ solves a genuinely annoying problem - clay compaction - in a way that doesn't need repeating every season. It's not exciting, but it's the kind of product that quietly makes everything else you plant work better.
Does exactly what it should, day in, day out.
