Diy block paving advise - Advise needed

I hope you are so wrong MSH and Bradstone should not only replace the dodgy ones but also pay for a contractor to do the job.

Just imagine if i paid a paving contractor to lay them and saying sorry mate but the flags you have laid are contaminated and not your fault but Bradstone but can you for FREE lift all them up and relay some new ones that they are replacing them with........i don't think so.

Bradstone should replace and pay for a contractors labour to lift and replace.

"In the unlikely event of products reaching you in a less than satisfactory condition, please refer to your stockist immediately, allowing time for the rejected product to be replaced. If a complaint is raised after laying the product, Bradstone cannot accept responsibility for any defect"

Just had an email and i am hoping that the Bero works as it saves alot of hasstle.

Mickg...thx for the clarification and the defect was not evident only on a couple untill they was laid , but still it's a pain in the ass and another job to add to my list .

Sent: 04 August 2009 10:44To: Joanne Chapell Subject: Fw: Defected flags Good Morning, I have looked at the photos and the paving is showing signs of Iron Oxidation.This Can be treated with a product called Bero.I will order some to go direct to the customers address below.Any problems please let me know.

I thought it looked like iron bits.

Best of luck. Keep us posted.

I am just a little worried now about applying the chemicals as stated below.

Bero also known as dichloromethane

What effect might dichloromethane have on my health?

Dichloromethane can affect you if breathed in and by passing through the skin. Exposure to high concentrations may cause unconsciousness and death. Exposure may irritate the lungs, which can cause a build up of fluid (pulmonary oedema). Lower doses may cause headaches, fatigue, and behaviour similar to being drunk. Dichloromethane exposure may cause the heart to beat irregularly or stop. Long term exposures at high levels may damage the liver and brain. The International Agency for Research on Cancer classifies dichloromethane as a 'possible human carcinogen'. Worksafe categorises dichloromethane into Category 3, a 'suspected human carcinogen'. It is possible that there is no safe level of exposure to a carcinogen.

What are you going to dab a bit on your pavement or drink it!:laugh:
Nah seriously you'll be working in the open but if your still unsure wear some disposable gloves and face mask.
It'll be great if it works

Also beware of the following side effects.
Rash, ringing in the ears, headaches, dizziness, drowsiness, abdominal pain, nausea, diarrhea, constipation and heartburn. reduce the ability of blood to clot and therefore increase bleeding after an injury. May cause ulceration of the stomach or intestine, and the ulcers may bleed. Sometimes, ulceration can occur without abdominal pain, and black, tarry stools, weakness, and dizziness upon standing (orthostatic hypotension) due to bleeding may be the only signs of an ulcer. reduce the flow of blood to the kidneys and impair function of the kidneys. Fluid retention (edema), blood clots, heart attacks, hypertension and heart failure have also been associated.
If you take over the counter Ibuprofen!

That's more than oxidation: there are iron particles within the mix, probably introduced with the fine aggregate (sand). While the Bero jollop will remove the rust, the remaining iron will then be exposed to the atmosphere and will.....rust!

I'm becoming increasingly concerned about some of the concretes being used in the paving trade. I've seen quite a few concrete flags, from various manufacturers, with iron content this year, and a worrying incidence of concrete supplied specifically for PIC work that has a higher-than-normal incidence of lignite (think fossilised wood) which then degrades and leaves holes in the very expensive surface. Manufacturers and suppliers can (and do) claim that the presence of such contaminants is only to be expected, but, in all honesty, if they are selling a premium product, it's not all that difficult to screen/filter/float out these contaminants and justify the price they charge.

Anyone here used Bero ?

Also i know i might be going on a bit here ...VICTAR MELDEW STYLE but , i have worked my butt off in making sure the surface is has been prepared right and laid it on sand/cement as adviced only to be let down by an inferiour product now which i think has spoiled ALL the job and i hope they send me enough to do the full lot as on the site it states that the BERO comes in 1 ltr bottles and should be used over the full area and not in patches.

[Rich H]

dichloromethane? isn't that ether?

[n0chex]

Ok an excellent service from Simply Paving & Bradstone as the Bero arrived this morning 4 x 1 ltr bottles all i need now is the weather to be ok for a day or so while i apply it and let it do its work for 24hrs or so.

Again thanks guys for your help and comments.

I'm sure artists use DCM so it cant be that bad

[Tony McC]

Make sure you let us know the results....we wait with bated breath!

[Bob_A]

Hope it works for you n0chex.
If it doesn't then at least you've done what the manufacturer have asked and then it's back to them again.

[n0chex]

Tony mc ......Will do mate and thx for posting.

Thanks Bob_A and i have my fingers crossed also but i may wait a few more weeks before applying the Bero solution as that way it will give the paving to show any more areas that need treating or am i wrong in saying that as once this Bero is applied it will stop any further iron oxide spots from appearing ...> ?
