Section repairs + pavement repairs! Sasebo Park Skate Park
Seal Hard Skate Park Renovation Specifications
In just one year since its opening... the skate park has transformed into a facility better than when it first opened, thanks to section repairs and surface renovations.
The "Sasebo Park Skate Park" in Sasebo City, Nagasaki Prefecture, was opened a year ago. "Is it already in need of repairs after just one year??" I think many people feel this way. The park's sections and concrete surfaces deteriorate faster than expected if they lack durability. At this time, we are repairing the sections (by Tsutomu Manufacturing) at the Sasebo Park Skate Park, while also using a large American grinding machine to smooth out the rough concrete surface, creating a flat surface. Additionally, we applied a permeable surface hardener "Seal Hard" and a water absorption inhibitor "Aqua Pel Plus" to improve wear resistance and rainwater resistance. Finally, we tested it with skateboards to confirm whether the grip feels appropriate. After the renovations, local skaters expressed their surprise, saying, "I thought the surface itself was fine, but after skating on the renovated surface, I was amazed at how much better it felt than I expected!" "Why is a new park already in such bad shape?" This is the most common question I hear from various park managers. We need to seriously consider "the aging of parks" before such situations arise!

basic information
Seal Hard Skate Park Renovation Specifications - Surface Concrete Grinding: The surface irregularities will be ground down using a large grinder made by American company STI. - Joint Leveling Grinding: The uneven joint areas will be ground down using a medium-sized grinder to level the height and eliminate the step. - Joint Filling Repair: Joints that were about 10-20mm wide will be filled with American-made fast-setting repair mortar. - Surface Depressions Resin Filling Repair: Areas that remain depressed even after grinding will be coated with a special resin made in the USA. - Surface Concrete Finishing Grind: Final grinding will be done to achieve a smooth surface. - Application of Penetrating Surface Hardener Seal Hard: This will enhance wear resistance and create a surface that can withstand wear from skateboarding. - Application of Penetrating Water Absorption Suppressant AquaPel Plus: This will suppress rainwater penetration and prevent surface deterioration caused by rainwater. - Skateboard Test Run Confirmation: The finished surface will be tested with a skateboard to confirm that it provides the necessary grip for skateboarding. The penetrating concrete surface hardener has the weakness of being vulnerable to rain and having low effectiveness outdoors. Therefore, by combining diamond grinding with the water absorption suppressant "AquaPel Plus," we have eliminated this weakness and developed a method specifically for skate parks, which is currently under patent application.

Detailed information
-
Grinding the surface damaged by rainwater with a medium-sized grinder made by American STI.
-
Fine areas are ground with a special handheld grinding machine.
-
The diamond blade is mounted on a medium-sized polishing machine, the same as the grinding process, to smooth the surface through polishing.
-
We will apply the penetrating concrete surface hardener "Seal Hard." With the effect of Seal Hard, the deteriorated concrete will gradually harden and transform. Seal Hard is a non-film-forming penetrating type, so it will not peel off. However, the penetrating hardener is vulnerable to rainwater, and when exposed to rainwater, the penetrating components will dissolve and wash away.
-
We will apply the permeable water absorption inhibitor "AquaPel Plus." AquaPel Plus is a hybrid water-repellent material based on silane and siloxane, which repels water like beads immediately after application. It compensates for the weaknesses of seal hard that are vulnerable to rain, transforming it into strong, rain-resistant concrete.
-
If too much Aqua Pearl Plus is applied, the grip will weaken and cause slipping during turns. Therefore, staff skilled in skateboarding will actually test it on a skateboard to check the resistance while sliding and the grip during turns. If any issues are found during the check, adjustments will be made through re-polishing or other cleaning methods.
