London stone catchup - Few photos

[davowolf]

I've a couple of questions relating to my patio and steps which were laid about 2yrs ago; just trying to upload the photos -

...ouch....

My questions really arise from the weathering you see and how it was all laid down 2y ago.
1. Blotching on the slabs. Could this be due to standard mortar being used directly under the slabs? Its as if damp in coming from underneath.
2. The wall still has efflorescence but less than it was; could this be due to the retaining wall having no concrete support or damp membrane, soil-side?
3. Those bricks for steps look permanently damp and are growing moss as you can see. There was no concrete support under these brick - they were laid on mortar only.

...and just for interest here's what it looked like under construction 2y ago;

Crossed joints. Very naughty!

I think it *is* Modak which is a porous stone prone to algaefication. The weak-looking joint mortar is probably acting as a wick for moisture.

Can't comment on the bwk eff as that stuff is a law unto itself!

Step moss - probably due to them being a porous substrate on a bank which will be fed by moisture from the upper garden.

Pete,
I can only comment on the look of the patio, and it is nothing that a good clean wouldn't cure for you.
There is one of our mixes in the stain removal section on the main site that would sort this for you.

We've started extending our outside display at our showroom in heathrow.















There is going to be a stream down the middle and some steps coming down from the existing display to link the two areas together

[London Stone Paving]

Were also planing to increase the size of the interior showroom. We need to move most of the staff facilities into this new building to create space to renovate the interior showroom. It needs plastering, decorating and carpeting. Should be done within 2 weeks

what bond is that ? brook bond
to half bond block work you have a 100 mm cut in alternate corners,or a 3/4 and a 1/4 every 2nd course

The lads are really cracking on.

Scratch coat on the outside walls





these steps will link the old display and new display together.





This is going to be a raised seating area.



Were trying to incorporate as many steps and coping stones as possible.

Theres a couple of things in there for Luton to spot, lets see if he gets them ?

[lutonlagerlout]
