Common questions
What people ask about interlocking blocks.
Five questions we answer most weeks. If yours is not here, ring the yard.
How tall can I stack them? +
A free-standing wall of standard 1600×800×800mm (5'3"×2'7"×2'7") blocks is good to 4 courses (3.2m / 10'6") in most applications without a tieback. Higher stacks need engineering — we can supply a tied-back design or a wider footprint with two-row blocks below the third course.
How heavy are they? +
The standard double block at 1600 × 800 × 800mm (5'3" × 2'7" × 2'7") is 1,485kg (3,275 lb). A 16-tonne teleporter handles them comfortably. Single 800 × 800 × 800 (2'7" × 2'7" × 2'7") blocks at 745kg (1,643 lb) lift on a smaller machine.
Do they need a foundation? +
Just a flat compacted MOT Type 1 base, 200mm (8in) thick. The blocks are heavy enough that overturning is not the issue at typical wall heights — it is the bearing. Soft ground gets a wider base.
Are they Beton-style? +
Yes — twin-lug pattern compatible with the common European interlocking block. We can interlock with most other manufacturers' blocks where the lug pitch matches; ring before mixing.
Lead time? +
Catalogue blocks ship in 2 to 4 weeks. Stock often available for the standard double — ring the yard for current availability. Painted blocks (a popular ask for boundary walls) run 4 to 6 weeks.
