Permeable Resin Mortar System Construction Method Council PRMS Multifunctional Construction Method
It is a multifunctional construction method made of materials with excellent functional durability, which not only has a freezing prevention effect during winter but also possesses noise reduction effects.
The "PRMS (Palms) Multi-functional Construction Method" is a technique that fills the voids of the surface aggregate in drainage paint with elastic resin mortar. It uses special elastic aggregate (product name "PRMS Elastic Aggregate") and special urethane resin as filling materials, offering excellent durability, freeze prevention effects in snowy cold regions, and further noise reduction compared to drainage pavement. The "PRMS Elastic Aggregate" is made from recycled tires that have been chipped and coated with inorganic powder and resin, resulting in granules (approximately 1mm to 2mm) that optimize the elasticity of the recycled tire chips through coating, enhancing their adhesion to the urethane resin binder and significantly improving the durability of the elastic resin mortar. Additionally, the durability of functions such as preventing clogging of the voids in drainage paint has been enhanced. For more details, please contact us or download the catalog.

basic information
**Features** ○ Improved durability of elastic aggregates → Uses a special elastic aggregate 'PRMS elastic aggregate' as a filler. Waste tires are chipped and coated with inorganic powder and resin, resulting in granules (approximately 1mm to 2mm) that optimize the elasticity of the waste tire chips through coating. → Good adhesion with urethane resin binders. → A groundbreaking material that significantly enhances the durability of elastic resin mortar. → Improved durability of functions such as preventing clogging of voids in drainage coatings. ○ Freeze prevention effect → In indoor tests, it was confirmed that a 2mm ice plate formed on the test specimen was crushed when traversed by a test wheel, and this was compared with drainage pavement. → The freeze prevention effect was confirmed in test construction on actual roads. → Measures against freezing, such as black ice, are expected. ○ Noise reduction effect → Noise measurements (special tire proximity sound) were taken between the PRMS multifunctional construction section and the untreated section (drainage coating), resulting in an average reduction effect of about 3dB. ● For more details, please contact us or download the catalog.
