We have recently supplied several headwalls to a project on the A5 in Leicestershire.
The specification called for two coats of bitumen waterproofing to be applied to all buried surfaces. The bitumen waterproofing was applied at the factory allowing the Headwall to be lifted directly into place on site without the need for any additional work to be carried out. We can add bitumen waterproofing to any of our precast concrete headwalls if required and for more information on the range of headwalls we offer please visit our website, email sales(Replace this parenthesis with the @ sign)althon.co.uk or call us on 01603 488700 and we will be happy to help.
