Paving moulds are made from polypropylene and will last for years if properly cared for, they are engineered to be strong and sturdy enough to hold their form and flexible enough to allow for easy de-moulding.
Concrete can be mixed by hand, Concrete Mixer, or alternatively you can purchase bags of pre-mix and simply add water!
With these moulds you can manufacture paving bricks, flagstones, pool copings, floor tiles and maxi building bricks.
General Instructions for the Paving Moulds:
For DIY applications you need to assess what you want to do at your property, for paving of driveways, use the smaller sized moulds (1OOx1OO or 15Ox15O or the double cobble). The moulds are designed to produce bricks that can handle heavy traffic.
If you want to produce stepping stones for a pathway or flagstone pavers for an outdoor entertainment area or pool area, you can make use of the larger sizes (4OOx4OO, 2OOx4OO or 2OOx2OO). These sizes are all engineered to complement each other giving you a huge variety of design options.
Mould Release Oil
Requires a mould release oil.
Use a sponge to apply the mould release oil both inside and outside of the mould (makes for easy cleaning).
When oiling your moulds, do so over a bucket or tray to catch all of the excess mould release oil so that it could be used again.
Aggregates and Mixing
The most important factor is sourcing quality local aggregates, to keep your costs low. The best option would be, to go to your nearest builders supply store and ask for assistance, alternatively try and find a local crusher plant in your area.
Leave to cure for at least 24 hours and then you can simply flip the mould upside down and the end product will pop out. We recommend packing the freshly cast bricks on pallets and wrapping them with pallet wrap, this will keep the moisture from evaporating too fast and give you a stronger product.
Oxides/colouring and Mixing
Cement Oxide can be purchased from your local hardware. The coloring of your products will take a bit of experimenting to get your personal preference right. Use between 3-10% of oxide to the cement volume in your mix
When leaving your products to cure, always make sure that they are on a flat, level surface. If you do not have a paved/concrete surface, then put down some river sand and level out the moulds by working them into the sand.
Curing time varies depending on the humidity and temperature.
Please follow the guidelines in the manual.
De - Moulding and Packing of the Paving Moulds
Simply flip the mould upside down and your paver will pop out. Work carefully with the products, remember that your concrete has not yet reached its maximum strength and it will continue to get stronger every day until approximately 28 days when it will reach 90% of its maximum strength.
IMPORTANT TIPS TO REMEMBER.
Never take shortcuts on your manufacturing process or ‘skimp’ on aggregates. Take pride in what you are manufacturing, make sure that you are using the correct aggregates, the correct cement and use the correct ratios. If you manufacture high quality products you will be able to charge the correct, premium price and you have returning customers.
