Long story short
The blocks come uncleaned (we only remove the excess of the bitumen, we do not clean the T&G)
The blocks come bitumen free up to 50-60% , with T&G cleaned.
The blocks come bitumen free up to 90%, with T&G cleaned.
The blocks come bitumen free at 100%, with T&G cleaned and at this price the surface can be planed (then it's practically like new flooring).
This is what you'll get in a basic option.
This is included in our standard, full and premium options.
