PaveMate - Paving Sealing

	Sealing

Why bother sealing? You’ve just had your paving cleaned but even after only a few weeks (as in the top left hand part of the picture) moss, weeds. oil and other marks have started to reappear. This will happen because there is no barrier between the upper surface of the blocks and the environment. That’s why the blocks needed cleaning in the first place. After cleaning however, you can apply a paving sealant (as shown in the bottom right hand portion of the picture). The weeds, moss cannot grow in the jointing sand because the roots cannot penetrate the sealant and the oil cannot stain the blocks again because there is a barrier. What is sealing? In this context putting a non-porous substance (the sealant) over a porous surface (the paver and the joint). Whether new or old most forms of paving can be sealed. Obviously if it is applied to new paving it prevents the staining and marking in the first place.
What are the benefits, it costs money? Sealing may be particularly beneficial to some types of paving. It’s not just something to prevent staining or marking, it also maintains the structural integrity of the surface, particularly with block paving. Block paving sits on amongst other things a layer of sand. In between the blocks there is a joint usually filled with sand. Providing the base for the paving is properly constructed and the joints maintained the paving will function properly. Failure is usually caused by loss of jointing medium sometimes with catastrophic effects. When the jointing medium is lost the blocks start to move allowing penetration of the sub base. Water gets into the sand base washing it away and in some cases turning it into something akin to quicksand. Blocks can crack, sink and channel where there is heaviest load. Eventually the paving will fail and the only option is replacement. Sealing the joints and blocks can help to prevent this happening. We believe the benefits of sealing should include: Increased lifespan of the paving therefore gaining greater benefit from your investment Resistance to weed and other infestation Prevention of oil and other staining Prevention of damage to paving by action of freezing and thawing Prevents blocks from splitting, cracking or settling by heavy traffic Prevention of infiltration by water (a major cause of damage to bedding sand and thus stability of paving) Reduced maintenance costs Retention of jointing sand Reduction of block loosening and creep Reduction of action by water or ice on paving Who makes the world’s best paving sealers?
