Valid point Ninja. As a single stand of racking, I would agree. However, with sufficinct cross bracing, they could be strengthenged to counteract that. Also bear in mind, that 3000kg is the rating per shelf, and each vertical member has a SWL of 15,000kg. So from an engineering stand point, they...

2 light systems will be run. One for game purposes (interactive, can be shut off, dimmed, strobed... etc. The other will be for emergency lighting and self powered from batteries. If power fails, lights will immediately come on. Fire is my biggest concern. But there will be a number of exits...

I'm entertaining the idea of building an indoor paint balling arena. Basically, rent a warehouse and then build a self contained structure within it. I would like to make the structure out of pallet racking. Imagine Wickes with it's huge 3000kg rated shelving, but there are floors spanning...

So, biting the bullet, I chiseled off the bitumen from the concrete floor (not a DPM). Not a fun job. Floor is unlevel... Really unlevel.... like 25mm dips over 2m un-level. I then put down a 1:4 PVA primer (as I've read to do in the past on several sites) and the back of the PVA container...

I'll try and get some pics to make this clearer. But the situation is as follows: Used to be an oil boiler in the kitchen tied to an external brick chimney. Boiler has been removed, flue liner ripped out and bottom of chimney blocked up. I want to install a BBQ area just outside the...

American: Color GrAy (A for american) English Colour (Not lazy and dropping letters) GrEy (E for england) Not helped by the fact most default spell checkers and pretty much all programming languages use American spelling. :|

As far as brown and blue goes. The UK has been using it in appliance flexes since around 1985, so the change wasn't totally new for us. But the more I read into this, I would have said that JBR was correct in his 'it was a ruling that came from Brussels' as it has little to do with the UK...

Also, brown and blue should be known to most people, even per-harmonisation as the flex colors in a plug. And if you can't wire a plug, you shouldn't be touching wiring installs :|

The only way for people to stop acting thick and/or ignorant (or a more polite way to put it is misinformed, or naive). Is education, not insults. From experience, there's only one reason I've found for people to prefer to mock the naive, rather than educate them. And it's to keep them naive...

So, hypotrhetically... If I'd already dropped a bucket of water based leveling compound onto bitumen... what would happen? >.> Fubar.

Cool, pretty much what I though. Cheers :)

It's the old problem. Bitumen (not DPC, just adhesive) residue left from asbestos-vinyl floor tile removal. Bitumen is dry, but stable. Need to level it. I've put some experimental blobs of cement based leveller down in a couple of spots to test adhesion, and they seem to be stuck well...

We have some 18mm random length walnut engineered flooring to lay throughout our living room. This will be floated over concrete (with DPM and underlay). The room is 11m x 4m. planks to run parallel to 11m run. On all sites, I've read that large rooms need expansion gaps in them. What they...

Gut feeling off of that is that you'll need a pillar installed to take the load. Ensuring load is transferred to the ground in a suitable manner. On consideration of the risks that could be involved with a floor / ceiling combo. I strongly recommend a structural engineer be involved to make a...

Every time I read 'RSJ' in a post, I'll ask, is there is a SE involved? Generally speaking, a stud wall isn't load bearing and you will need some re-enforcing. This will possibly be in the form of a block pillar, or a second RSJ spanning the length of stud wall and properly supported at...

Wickes do (I think) 3 sizes of studding. Used a couple for various odd jobs and the quality is pretty good. Plasterboard (screwed on) will definitely add some rigidity. But stud walls will always flex. I hate them tbh, much rather have solid.

Normal lintel dims require 150mm contct area each side with a load bearing wall. RSJ could be different and dependent on: Load on RSJ Material it will be sitting on Lateral forces As you're using an RSJ, is a structural engineer involved? What's the project for? is this for a...

If it's a high rise, I would imagine all inter-apartment walls are structural. Should be able to fit a RSJ if needed. Only way to know for sure is to consult a structural engineer with the buildings plan. Also, check that you are legally allowed to make that modification. The building...

The inside stopcock is all well and good till it jams up and you snap the handle trying to close it. To my knowledge, the stopcock and meter are the property of your water supplier and access is required at all times for emergency work / replacing or inpecting meter. There are a number of...

So in 20 - 30 years time, New York is going to see a surge in asbestos related health issues. Begger.
