FAQs

What is the main advantage of Celcon Foundation Blocks?

The main advantages are their significantly lighter weight compared to dense aggregate blocks, enhanced thermal performance, and excellent freeze-thaw resistance, which contribute to easier handling, faster construction, and improved building efficiency.

Can these blocks be used for any type of wall construction?

Yes, they are suitable for supporting solid or cavity walls, framed construction, and suspended floors. They can be used both below and above ground (with appropriate finishes above ground).

How do I lay Celcon Foundation Blocks below ground level?

You should lay them with mortared horizontal bed joints and butt them together vertically. Mortar perpends are not required below ground level for these blocks.

Are these blocks suitable for supporting a three-storey building?

Yes, the product description states they can be used to support 3-storey constructions. However, always consult structural engineering specifications for specific projects.

What is the compressive strength of the Standard Grade block?

The Standard Grade block has a compressive strength of 3.6 N/mm².

Do I need special mortar for these blocks?

While they are compatible with standard masonry, it is recommended to use the manufacturer's specified or appropriate mortar mix for optimal performance, especially for below-ground applications.

How do Celcon Foundation Blocks compare in cost to dense aggregate blocks?

An independent report suggests Celcon Foundation Blocks can be up to 26% cheaper than dense aggregate blocks, considering material and labor costs.

Troubleshooting

Blocks are difficult to lay flat.

Ensure the foundation base is level and compacted. Check for any debris or unevenness on the block surface.

Concerns about below-ground moisture ingress.

Ensure horizontal bed joints are properly mortared. Consider additional DPC (Damp Proof Course) as per building regulations and design specifications.

Poor mortar adhesion.

Use the recommended mortar mix for Celcon blocks. Ensure surfaces are clean and free from dust or frost before applying mortar.

Block damage during transport or handling.

Handle blocks with appropriate lifting aids where necessary. Store them on a stable, level surface to prevent edge chipping.

Pros and Cons

Pros

Significantly lighter than dense aggregate blocks, improving ease of handling and reducing labor costs.
Offers improved thermal performance, contributing to better ground floor insulation.
Demonstrates excellent resistance to freeze/thaw cycles, ensuring long-term durability.
Potential for cost savings compared to conventional foundation blocks.
Streamlines the construction process, reducing build time and complexity.
Suitable for a wide range of foundation and wall constructions, both above and below ground.

Cons

Requires specific laying techniques for below-ground applications (mortared horizontal joints only).
Standard Grade has a lower compressive strength (3.6N/mm²) compared to High Strength Grade (7.3N/mm²), limiting its use in certain demanding structural scenarios.
May require specific finishes if used for above-ground solid wall construction.
Not suitable for all load-bearing applications where very high compressive strength is paramount without careful structural design.

Setup, Compatibility & Care Instructions

Setup:

Celcon Foundation Blocks are designed for direct use in foundation construction. For below-ground applications, it is recommended to lay blocks with mortared horizontal bed joints and butt them together vertically. Ensure the foundation trench is adequately prepared and compacted.

Compatibility:

These blocks are suitable for supporting solid or cavity walls, framed construction, or suspended floors, including beam and block systems. They are compatible with standard masonry construction techniques. For above-ground solid wall construction, ensure appropriate finishes are applied according to building regulations and design requirements.

Care:

Store blocks on a firm, level surface, away from direct prolonged moisture. Handle with care to avoid damage, although their lightweight nature aids in handling. Clean any excess mortar promptly. For below-ground applications, ensure the correct mortar mix is used for the horizontal bed joints as specified by the manufacturer or structural engineer.
