Is London soil clay?

How common is clay soil?
Clay is a very common substance. Shale, formed largely from clay, is the most common sedimentary rock. Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy.
How deep do you have to dig to get past clay?
Minimum depths
Strip, trench fill or pad foundations must be cast at a minimum of 750mm in low plasticity clays, 900mm in medium, and 1000mm in the highest risk areas.

Why is clay soil good?
“Clay soils hold huge amounts of plant nutrients because they have elevated cation exchange capacities,” said Brewer. This means they are able to hold on to nutrients, fertilizer and pesticides. Another plus for clay soils is that they hang onto water really well.
Can you plant in clay soil?
In fact, clay soils offer plants two major advantages over other soil types: they hold water well, minimizing drought stress, and are abundant in nutrients essential for plant growth. So, if you’ve been struggling to achieve your dream garden or landscape in clay soil, cheer up!
