<p>A 'Vee' section profile with an included angle of 90 degrees, >45 degrees and made of tough extrudable material such as rubber or flexible PVC is claimed for lining road borders to guide rain water away to ditches, drains etc. Strips of the prefabricated profile can be installed or replaced more rapidly than e.g. concrete kerbs built in situ, are said to be mutually more tolerant of tyres which impact or traverse the kerbs.</p> |
