Hills Quarry Products can readily supply materials that have been developed, using high air content concrete, for use in highway construction and maintenance. These materials may allow more rapid, reliable and cost-effective reinstatements, with less dependence on the skill and physical effort of the operators. These materials may also offer significant environmental or practical advantages, and/or cost benefits, compared with conventional materials, including various combinations of the following:
- Speed of reinstatement and decrease in open trench times and reduced liability of returned maintenance
- Lower energy requirements during manufacture and/or laying
- Self-cementing properties to improve performance, reliability of laying and compaction
- Self-levelling or flowable, to avoid or reduce the need for compaction and to provide health and safety benefits, reducing the amount of lifts
- Flow around pipes and into voids where conventional filling would be difficult.
This type of concrete is also suitable for filling redundant tanks, pits and cellars.
