Tarmac All-in Ballast, Large Bag

Have just used 39 bags for a slab of concrete; thankfully we collected them.
The seal on the back of the bags is rubbish; many will be split, so flip them over before putting them on your trolley.
The volume of ballast in the bags varies significantly; whether you compare 2 wet bags or 2 dry bags you will see some are half full. You're not paying half for them, so this makes me dubious of bulk delivery. When mixing concrete, this really does make this poor quality and mis-sold as it's underweight.

I recently did a concrete pad and needed some ballast on a Sunday so used the click and collect service. after getting through 45 bags it was clear to see some bags had over twice the amount of ballast in than others. I purchased from two didn't stores and all the bags had the same issue This made batching the concrete more tricky and I don't feel it falls in line with weights and measures regulations. As you are paying a set amount of money but getting varying amounts of product.

The first batch was large pea gravel, ie pebbles and sand. Difficult to work to cast slabs in situ with a mould, but the finished rough surface was suitable for a sloping path.
When I went to get more to complete the path the same Tarmac ballast was now crushed stone and a different colour. The appearance, both colour and surface finish, are totally different.

Tarmac Ballast - All In One Bag
I Have To Comment On How Absolutely Brilliant This Product Is & Its Quality, Cheap As Chips Too!
Use Just One Full Shovel Full Of 'Mastercrete Cement' To 1 Full Bag Of 'Tarmac Ballast'
(5 Shovels Ballast (1 Bag) To 1 Shovel Of Cement) & What Can I Say But The End Result Is Just Pure, Proper, Solid & Strong Concrete!!
I Would Highly Recommend This Product Which Comes In A Strong Plastic Bag & It's Very Easy To Mix With, Just Don't Add Too Much Water When You've Mixed Ballast & Cement Together, Add Water Bit By Bit, As Some Of 'Ballast Bags' Contents Could Be Already Be A Little Wet When They Are Bagged Up.

Bought a large quantity of bags as home delivery at the time was not available for bulk purchase due to covid. Was perfect mixed with concrete to form a slab for a wooden gazebo
