Frequently Asked Questions – Concrete & Building Blocks

What’s the difference between dense and lightweight blocks?
Dense blocks are heavier and offer greater compressive strength, making them ideal for structural work and load-bearing walls. Lightweight or aerated blocks are easier to handle and offer better thermal insulation, making them suitable for partitions and internal walls.

Can these blocks be used below ground or for foundations?
Yes, certain types of dense concrete blocks are rated for below-ground use and are suitable for footings and foundation walls. Always check the product specification or ask us for advice based on your project.

Do your blocks meet UK building regulations?
Yes — all our concrete blocks meet relevant British Standards and building regulation requirements for structural use, thermal performance, and fire resistance.

Are your blocks sold individually or in packs?
Most blocks are available in full packs, but selected lines can also be purchased individually. Product pages will show available options, and you can always contact us for large quantity pricing or delivery queries.

Do you offer delivery for bulk block orders?
Yes — we provide local delivery across our service area for block packs and bulk orders. Delivery options and lead times are shown at checkout, or feel free to contact our team for assistance.
