Hi could you tell me if I need to lay sharp sand down before I lay the sublayer cement? Or does it go straight on to sub base?

Hi,
Thanks for your question. For Blue Circle Slablayer you can go straight onto the subbase.
Thanks,

Can you place direct onto compacted soil?

Hi,

No, Slablayer should be placed on to a suitably compacted granular subbase material such as type 1 etc. soil can be very easily washed away or mined by insects.

Hope this helps with your question.

Thanks,

Can this product be used for laying a brick path in a garden?

Hi,

Thanks for the question. As a bed material yes, but it is not suitable for jointing as some particles are larger than 4mm.

Hope that helps and good luck with your project.

Thanks,

Hi there
Is this product suitable for using with porcelain outdoor slabs alongside a primer to create a bond.
Many thanks

Hi there. No, porcelain flags should be laid on a full ‘wet’ workable mortar bed typically a 1:4 (Blue Circle Mastercrete cement/sharp sand). The mortar bedding should be laid at a thickness between 15mm and 30mm. To increase adhesion to the mortar bed and avoid separation, a slurry primer or flexible bonding agent compound should be applied to the back of each flag prior to installing onto the mortar bed.

Can slablayer be used to lay porcelain patio slabs? If so, do you recommend using a slurry primer to coat the back of the slabs before laying onto slablayer? Thanks.

Hello, Can this product be put directly onto an existing concrete base?

Blue Circle Products
Admin

Hi there. Yes, but remove any loose friable material and dampen the existing concrete before laying. Note it is possible for movement joints and pre-existing cracks to cause problems in segmental pavements i.e. reflective cracking. Movement joints should be carried through into the new paving. With regards to cracks they are most likely to appear in joints within the new paving, as opposed to damage of the units, however it is still possible for them to cause movement or settlement issues.

Hi,

Can this product be applied on top of old concrete slabs?

Blue Circle Products
Admin

Hi there. It is not recommend to lay new paving on top of old paving. Typically it is not known how the existing slabs have been laid and if the laying method or subbase is capable of supporting the extra weight or the new paving, secondly any defects of or movement in the existing slabs may be reflected in the new slabs above. Its also worth noting where paving is alongside a property the finished height should be at least 150mm below the DPC.
