weakens the material and leads to bigger, more complex damage developing.
To repair small cracks now, use a filler that is waterproof so that once the product has been applied, water cannot penetrate the area and weaken it. Watco’s Asphalt Crack Filler provides long lasting protection against water and allows movement of the surface due to its flexibility.
Heavy-duty repairs Heavy duty repairs are required when minor damage has been left to deteriorate, or sometimes when significant damage is created by the impact of heavy equipment being dropped on the floor. This can occur in outdoor spaces such as loading bays when heavy inventory or machinery is being transferred to and from transport vehicles.
This type of damage – large cracks and holes with lots of loose material - is easy to spot, but depending on the size and location of the damage, it also poses a safety hazard for teams working in that area and can also cause further damage to equipment and vehicles that need to cross the surface.
To complete a heavy-duty repair, start by clearing the surface of any loose material, water or oil. For asphalt repairs in a loading bay, Watco Bitu-Mend Advanced is ideal because it’s long-lasting, cures to a hard slip resistant finish and can be ready for traffic in just 12 hours to reduce downtime in that area. Simply mix together the curing agent and resin tin in the larger container and mix thoroughly with a wide bladed tool. As soon as they are mixed, pour into the void you are repairing and work into any gaps with a trowel. Lightly compress with a piece of

wood to remove the air pockets then finish with a trowel to ensure the surface will be level and leave to dry.
Localised repairs Localised damage occurs when an asphalt surface is pushed up against a different material, such as metal or concrete around manhole covers, drainage gullies, ramps, door thresholds or by metal tracks for roller shutter doors.
Damage to surfaces around the areas outlined is common because of the level of traffic and movement on a daily basis. For example, frequent opening and closing of roller shutter doors will create vibration, which would loosen the materials in conventional asphalt repair product and lead to cracks and holes forming. Therefore, repair products must be selected for their durability and ability to withstand movement.
A powerful epoxy resin, such as Watco Concrex Asphalt Repair, will work best for this because the product is designed to stick to other materials such as metal and withstand heavy traffic to hold the repair in place. To prepare and apply the product, follow the same process as the Watco Bitu-Mend Advanced. Clean the damaged area of loose material or liquids, then mix the two tins together with a wide bladed tool and apply to the surface. Compact the product with a piece of wood to remove the air pockets then finish with a trowel wiped with white spirit for a smooth finish.
