Concrete & sub base calculations and resin drives - How to measure how much material needed

[DRIVEMAN]

I HAVE JUST STARTED WORKING WITH RESIN BONDED DRIVES
HAVE RESEARCHED WELL WITH DIFFERENT MANUFACTURERS BUT THEY ALL HAVE VARYING IDEA'S ABOUT EXPANSION GAPS.
SOME SAY THEY IGNORE THEM AS IN ROADS OTHERS SAY FILL IN THE GAPS WITH EXPANDABLE FILLERS, AND LEAVE THEM SO THE CAN BE SEEN AS RESIN OVER THE TOP WILL CRACK.
FROM MANUFACTURERS WHO HAVE BEEN LAYING IT FOR YEARS.
PS WHAT IS A QUICK AND EASY WAY TO CALCULATE CONCRETE FOR DRIVES AND FOR SUB BASE MATERIALS.
ALSO I HAVE ONE JOB AT 15.5 MTRS LONG BY 5 MTRS AND ANOTHER 14X3 MTRS THEY BOTH NEED CONNCRETE AND RESIN BOND AND BROADCASTING.
AM GOING TO USE READYMIX , WHAT ABOUT REINFORCING
ON THAT SIZE AREA AND A GUIDE TO COST PLEASE MANY THANKS.VERY GOOD SITE. DM

First of all, knock off Caps Lock when you type. Using all upper case test is the internet equivalent of SHOUTING!

I don't know who;s telluiing you to ignoire expansion or movement joints, but they shouldn't be in the paving trade if that's their advice. All movement joints must be brought up to the surface, otherwise there is a real risk that the resin surfacing will crack when there's movement of the substrate.

Concrete is bought by volume, so it's simply a matter of 'cubing up' what's required - length by breadth by depth, plus an allowance for wastage. Sub-base material is bought by weight, and I recommend you read the sub-base pages on the main website for further information.

It worries me that you are installing these materials yet seem unable to work out how much will be needed. The ability to perform what are rudimentary calculations for materials is a basic skill for anyone claiming to be a quality contractor.

I'm not prepared to calculate prices for you - if you can't work out how much is needed, and how much it should cost, it suggests you shouldn't be involved in the installation. That may seem hard, but that's the way it is - this website is all about promoting best practice: taking money from the public to undertake a construction task when you don't understand what's involved goes against everything I believe in. You should get yourself some proper training, spend time working with an experienced, professional contractor before launching yourself onto the unsuspecting public, otherwise all you'll do is reinforce the public perception that all of us in the trade are little better than cowboys!

WAS BROADCASTING???

Ill give you an idea of the amount you will need..... all you need to do is give me the third part of the equasion....I can then work out the cm.

The you can take this the cm your suppliers and get them to price.

Have you been specified to use reinforcing bars for the concrete base?
Was it on your drawings?
