Brick wall property getting infected and membrane put in thabks

If the guarantee is from an insurer, that stands more chance of being reliable than if it's from only the contractor.

Can someone give me an estimate for a blue brick damp proof couse on average sized semi? Not moved in yet, but it will need doing as soon as possible

There is no such thing as blue brick D.P. C.

[gardenguru]

well what are blue bricks for then?

[big_g]

Do you mean fitting a layer or two of the engineering bricks into an existing wall? Not a builder myself but would an injected damp proof course not do a similar job?

There is no such thing as blue brick D.P. C.

Of course there is and it is the best damp proof coarse available.

The blue brick D.P.C. is usually laid before the floor joists are fitted at ground floor level.

The best practise is to lay two courses of blue brick at half bond to each other[tight joints].

 

To fit a blue D.P.C. in an existing building is an intricate and time consuming proceeder also expensive as the bricks as well as the labour are costly.

 

We have fitted many of these in existing buildings with 100% success.

The injection system is usualy a con and is no good whatsoever without the internal waterproof rendering up to one Mitre high .

This render alone would probably do just as well in most cases.

I agree with Cuttsie,both regarding the blue bricks and the chemical DPC.The blue brick method is very expensive,sorry,costs a lot of money,due to the labour costs for the meticulous method required to install them.Don't forget that the inside leaf wants doing aswell and this is required below the level of the floor joists.

Don't have this sort of work done by anyone you don't have 100% confidence in,and who doesn't have good liability insurance!

This render alone would probably do just as well in most cases. Their is no such method in a new build. Only used in a patching capacity. In a new build to match existing house you put 2 course of blue bricks .[ Type with a blue face on] and then lay a d.p.c. on top. A proper blue brick would probably cost £5 each. Just after the war they used to use them as they were cheap and d. p. c. membrane was none existing. Water still came up t he joints . They tried putting waterproof in mortar mix still no good. Been a bricklayer for 60 years. A load of rubbish about keep tight joints/ Put some water repelent in mortar mix if you want. At the end still put a membrane d.p.c on top of 2 course blue bricks about £2 a roll and does job correctly. :loopy:
