Appropriate construction work is essential for the demonstration of excellent functions of Polyroof. Therefore, we have established a nationwide construction work system by forming the Polyroof Industrial Association in cooperation with about 200 companies engaged in waterproof construction work throughout the country.
We offer a long-time guarantee through tracing our construction work based on the analyses of preserved construction records by lot.
To waterproofing glass mat, we apply the allowance standards of (+) 20% and (-) 5%, which is stricter than ± 20% regulated in the JIS standards.
In order to satisfy customers' demands and comply with the water quality standards in water supply and fireproofing regulations in the Construction Standards Act, we implement construction work after confirming the inspection results at public institutions.
