laying slabs

I was refering to under floor ventilation, required for timber floors, not seen much now in modern houses.
As you say room ventilation will be higher up.
I dont think the position of air bricks should be used to decide the height of the DPC.
If there is a DPC, it will be visable, I would think.

 

Excellent!..Supply only from now on with Garage doors.. Thanks Nathan..saved me a fortune :D

 

Pete is correct about 6" below dpc otherwise you could create a damp problem when i done my paths along side the house i had to remove them simply because they were 6" below dpc and if i had left them there and laid on top i would have only ended up with approx 2.5 inches below dpc and i wanted to maintain 6" below dpc.

Regards the edging you can bed this in sand cement alongside the fence or even tight to the fence why cant you lower the ground across the house to give you 4" > 6 "better to be on the safe side rather than have a problem later.

Pete is correct you should maintain 6" below dpc otherwise you could have a damp problem why cant you lower the ground by the house to achieve this like you said its not a large area.

When i laid slabs around my house i had to lower the area simply to maintain 6" if i had laid on top of exsisting i would have lost approx 4" that is not recomended.

The edgeing can be laid in sand and cement either quite close to the fence or even tight to the fence and the side of the edging you cant see put sand cement behind it will prevent it moving anywhere.

 

the original idea using the mesh backed setts, was to avoid removing the existing concrete path, tho it mite be better to do so and in fact, we will probably have to in the end to get all the levels round the door to work, also the edging will need to be set in a proper concrete haunching, [sand and cement has been used all over this garden without success as the soil is so light it tends to disperse and then the edgings collapse, in fact i ve already removed yard and yards of home made edgings for this reason].

 

Hi

Pete is correct about 6" below dpc during the past when i have laid slabs for people around their properties i have had to remove old paths even if they were good i had to maintain 6" below dpc if i had laid on top of exsiting then i wopuld lose 3>4 inches thats not good because it could cause damp problems at a later date.

Why cant you remove the area by the house you state its only a few meteres better to be on the safe side.

Regarding the edging you say there is a fence you can put the edging quite close to the fence bed the edging stone in sand and cement and put cement behind the side you cant see ie by the fence that will help keep them in place

 

I am not sure what happened here but somehow i have sent three replies i am sorry about thst but i did have a few problems last night on the computer.
