Joint sand used for paver applications should be a course, washed concrete sand. This sand takes more time to get into the joints, but is also more difficult to wash out. Do not use silica sand or mason sand. The joint sand should also be completely dry. If the sand you have is damp, spread it out to dry before using. Wet and damp sand will prevent it from flowing freely into the paver joints.
Drinking eight cups or two litres of water a day is longstanding advice. But is there any scientific basis for it, asks Dr Chris van Tulleken.
You are probably all aware of the âcardinal ruleâ that says adults should drink six to eight 8-ounce glasses of water per day. The truth is, this is an estimate and the actual amount you should be drinking per day can vary quite significantly. There are multiple factors that can impact how much water you should be drinking.
