PolyBrick® Bespoke Raised Bed Planter Kit

Really good product. Sturdy but lightweight. Can be a bit difficult to get apart and sometimes a struggle to get them together perfectly, but once done great. Holes line up so I was able to put hanging basket poles around which is really nice.

If you had Lego these are easy to assemble. Just give them a gentle tap with a rubber mallet to get a tight fit.

As this was an unknown product I started out with a raised bed kit. This exceeded expectations so I went ahead with an order for our main project which was to cover/replace the rotten wood on our raised beds. This really was as easy to put together as lego. Hold in position, a tap with the rubber mallet and move on. Our original planter ran at an angle but because the blocks are hollow and plastic we could manoeuvre them slightly to not leave gaps. We inserted some rebars to ensure the weight of the earth behind did not push it out.
I am really pleased with the finished results and know I will not have to replace this in 10 years time like the wood. Thank you polybrick for a smooth process.

PolyBrick® Double Cap

We love our introduction to your product. The response time to online queries was excellent and time frame from order to delivery I don't think could be improved. The product itself really is as easy as child's play so very confident to go forward with our next project
