Frequently Addressed Technical Enquiries
Clear technical answers regarding British Standards compliance, operational containment, and delivery parameters for commercial clients across Norfolk.
What specification of block paving is required for heavy commercial traffic?
Commercial vehicle areas require heavy-duty 80mm interlocking rectangular concrete setts laid in a 45-degree or 90-degree herringbone pattern over a compacted sharp sand bed, designed to BS 7533 standards to resist turning shear stresses from multi-axle HGVs.
How is an Armco crash barrier installed on commercial yards?
Armco corrugated steel barriers (conforming to BS 6180) are mounted on heavy steel RSJ posts, either bolted down to reinforced concrete slabs using heavy chemical anchor studs or cast directly into deep mass concrete ground sockets to protect buildings, fuel tanks, and walkways.
What approvals are needed for a commercial vehicle dropped kerb?
Commercial dropped crossings require formal approval from the local highways authority under Section 184 of the Highways Act 1980, ensuring appropriate asphalt binder courses, reinforced concrete sub-bases, and heavy-duty granite or concrete kerb stones capable of supporting 44-tonne vehicles.
