Why is it Important to seal cracks?

Sealing of cracks is a critical maintenance activity because it prevents the entry of water, chemicals and other non compressible substances such as dirt, rocks, weed growth, etc. The entry of all of these materials into cracks accelerates the rate of failure of the pavement. Traditional crack sealing products require heating prior to application in order to turn them into a liquid for filling of the crack. The requirement for heating engenders cost for specialised and complex equipment, specialised training and work processes; and HSE risks. Traditional crack sealing products also require significant preparation works which include activities such as ‘routing’ (or widening the opening of the crack via mechanical means) prior to application. our ‘Crack Seal’ product is a liquid at ambient temperatures. It requires only that the cracks be cleared of deleterious material by high pressure air. It is important to note that left unsealed, cracking will eventually lead to complete failure of large areas of pavement. These areas will then require expensive heavy patching as a minimum response to fix them.

How ‘Crack Seal’ Works

The section of pavement under repair is thoroughly cleaned by suction sweeping or high volume ‘blowers’. The cracks are then ‘blown’ free of debris using compressed air. Following this the liquid Crack Seal is poured into the cracks. Finally, excess sealer is ‘scraped’ flush with the surface each side of the crack. ‘Crack Seal’ provides a permanent seal and may be used in combination with PotHole Fix and PRS to cost effectively and sustainably remediate large sections of pavement.
