Tarmac Repair Bags
If you are a builder’s merchant, chances are that you will already have a ready supply of Tarmac Repair Bags. Such bags are actually cheaper than having hot tarmac delivered in smaller quantities. Tarmac Repair Bags cost approximately five pounds per bag and each bag will contain twenty-five kilograms of tarmac. This price is the equivalent of paying two hundred pounds per tonne and is of course a lot higher than the normal rate which is between thirty-five pounds and forty-five pounds per tonne ex works.
Tarmac – purchase more than a tonne
Even so, the cost of a one tonne load will include part-load charges of around one hundred to one hundred and twenty pounds and so when purchasing hot tarmac you should try and purchase in quantities that are greater than one tonne. This will ensure that you will get hot and fresh tarmac and at a decent price as well.
Covers .45 square metres
Tarmac Repair Bags that contain twenty-five kilograms of material will help in covering about .45 square metres at 25 mm thickness. However, it is not a good idea to have tarmac surface that is less than seventy millimetres. This means that you will require six Tarmac Repair Bags to cover each and every square inch.
Most pre-packed Tarmac Repair Bags are cutback varieties which mean that they have been doped in order to retard the setting until it can be exposed to the atmosphere which is when the doping oil will simply evaporate. The bags will be supplied in cold condition but the work must ideally be done with hot tar. This means that you will need to leave the bags in a warm place.
Before use, take the tarmac out of the Tarmac Repair Bags and spread it out according to needs and compact it down to level in a similar manner as is done with hot tarmac. You should expect the doping oils to take a few weeks before they completely evaporate but the tarmac itself will be ready for use almost immediately.
Sometimes, the surface of the repaired tarmac may remain somewhat tacky and it can also be picked up by the tires of passing cars or they can stick to the soles of walking shoes. To prevent this, simply dust the surface with the help of some fine sand in a manner that is similar to flouring work surfaces. Over time, the sand will wash itself away.
Ideally, small sized Tarmac Repair Bags should be used to affect minor repairs but should not be used to repair areas that are greater than a few square metres. The tarmac will also remain quite soft for a few weeks and can therefore be penetrated quite easily by any load such as a sidestand or a stiletto heel.
If you need to patch areas that are of two to twenty square metres you can use several Tarmac Repair Bags and also get a tarmac contractor to do the necessary work. Remember also that tarmac can best be patch repaired and the patch will be visible to the naked eye. A good contractor should be able to minimize the visibility of the patch.
