Order concrete blocks for delivery in Harwich

Concrete blocks are large masonry units, normally 440 × 215 mm on face, that lay at about 10 blocks per square metre; they come as dense aggregate, lightweight aggregate or aircrete (aerated) blocks.

We deliver concrete blocks to sites, driveways and yards across Harwich, from a single pallet for a small job to full loads for bigger builds.

What concrete blocks can we deliver to Harwich?

  • Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.
  • Aircrete (aerated) blocksVery light, easy to cut and good insulators; check the strength grade for loadbearing work.
  • Hollow and cellular blocksLighter dense blocks with voids, used for some garden and retaining walls.
  • Block paving and edgingsOn request alongside your sub-base and sand.
  • Trench and foundation blocksWide blocks laid in foundation trenches instead of lots of concrete.

Getting concrete blocks onto your Harwich site

Blocks are banded on pallets and usually crane-offloaded where the vehicle and access allow; tell us the weight limit of any drive or the ground where pallets will sit. Harwich is inside our standard mainland delivery area.

  • If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
  • In summer Harwich gets around 16h 43m of daylight, but early deliveries still beat the traffic and give the longest working day.
  • Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Getting the right concrete blocks

What strength do I need?

Most houses use 3.6 N/mm² or 7.3 N/mm² blocks. Your structural design, your building control officer or the block manufacturer's guidance sets the grade; tell us what is specified and we will match it.

Handling heavy blocks

Health and safety guidance discourages laying very heavy blocks by hand for long periods. Lighter blocks or planning the lift can make a big difference on site.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
