How to prepare and apply UltraCrete Tough Patch

1. Permanent repairs require best practice in saw cutting around the defect or opening to ensure straight, vertical edges that support compaction of material when installed.
2. Remove any debris, mud, silt or ice from within the defect.
3. To enhance the longevity of the repair, seal the vertical cut edges and base of asphalt defect or opening with Ultracrete SCJ Seal & Tack. This is essential when the substrate is concrete.
4. Apply Tough Patch from the bag or bucket using the layer method (see below) which ensures uniform compaction and longevity of repair.
5. Loosely spread each layer uniformly into the defect or opening using a shovel or rake.
6. Before compacting each layer, sprinkle water over the complete surface at the approximate ratio of 1litre per 25kg bag of Tough Patch – this will activate the curing process.
7. Mechanically compact the material in accordance with Appendix 8 of the SROH and repeat the process for all layers ensuring the material final layer is slightly proud of the surrounding area and fully compacted.

How to apply Tough Patch for emergency repairs

For emergency repairs, saw cutting (step 1) and thorough cleaning (step 2) may not be able to be fully undertaken due to traffic management requirements, therefore the material can be used in an emergency or in reactive maintenance programmes to prevent pedestrian, vehicle or cycle harm or damage, with the knowledge that a more permanent solution can be carried out at a later date.

During an emergency repair the pothole may be filled in one application. Compact using a suitable tamping device or in areas where there is limited traffic management in place, allow traffic to compact.

It is the responsibility of the user to satisfy themselves on the effectiveness of the application.

Layer installation method for Tough Patch

Tough Patch 6mm for paving is generally installed at a max 60mm depth in accordance with SROH. This is applied in layers as follows:

• Apply product to a depth of 45mm and compact to 30mm for first layer
• Repeat process to achieve a total 60mm finished depth.
