Problems with marshall paving - Advice please

[ii_paving]

I have a problem with some Marshalls Heritage slabs. Some of them have flaked and developed discolouration & blooming.

We had 3 sizes of slab laid. 2 of them suffer from the problem one doesn't - even though they have common joints.

I have had repeated contact with Marshalls and the contractor - but have got no nearer a resolution, other than both agree that there is a problem.

Marshalls state it is a laying / pointing problem. The contractor says it is a manufacturing fault.

According to the contractor the slabs were "laid on sand/cement morat bed on compacted Type 1 base. The joints were wet pointed and raked. Other parts of your patio's and the other thousands of metres we have laid (including vast amounts of Heritage) have never suffered from this problem"

Can you please advise how I can take this forward ?

My opinion (for what it's worth) is that it must be a manufacturing problem because slabs of one size don't have the problem at all.

apologies for the long post..............

If you have purchased the flags yourself then the retailer should be arranging for a representative to come out and diagnose the problem etc - if the contractor supplied and installed, he should be in touch with the retailer or Marshalls direct (if they have sold direct to the contractor).
Either way - you should expect good back up from all parties, especially if (like you say) you have purchased thousands of metres!!!!

Have the slabs flaked throughout or just towards the edges? What size is the slab that remains ok?

Need to see pictures. Flaking could be a number of things. Bloom - IF it wasn't evident before installation - may be down to installation.
