Finishing touches - Cracked block + sealing

[De1b0y]

Thanks to everyone who answered some very basic questions over the last 6 months.
Rain held-off sufficiently for me to complete my driveway! 44m2 in total done in 50mm Drivesett Traditional.
Two final points.
1) Two blocks cracked and 1 removed very easily, but one cracked after KDS. Can't shift the thing!! Have read the website and levering with two chisels just doesn't work. Thinking of going for the 'destructive method'; whack it with a wide chisel at 30 degrees. Any views on this?
2) Read up on sealants on website. Does not seem to be strongly recommended for domestic driveways. Has anyone views on the value of sealants with Drivesett Traditional and in a domestic situation? "Wait 12 weeks from original laying/jet-clean/reapply some KDS/leave for two weeks before applying sealant" seems an awful fuss. Does anyone really follow these rules? Is any sealant better for Drivesett Traditional
Many thanks

either drill it or bolster it, it will come free. sealants are a nice to have in your situation, as i dont think you really need to pay out for this, but then i am a heathen!:p
