Simple, but very very effective
I used this on a gravel base to lay a base for a shed. It does the job perectly. It's easy to click together to make whatever size you want, cuts easily, and has given me a good solid base for the past year or so. I checked a few days ago and the shed is still level so I have had no slippage, which is more than I can say for everything else in my garden. I will be purchasing this in much larger qualtities in the near future to help fix my trip-hazard of a patio once I decide whether I want gravel, decking, or flags. I'd trust it to do a good job for any.

Great product
When I received this I didn’t know I may have to cut it to size. But the company took it back and they have refunded me. I got another one from them that I didn’t have to cut to size. This would have been very good for the shed base or for a drive way. It's very well made and sturdy. Over all I am very happy now with the company and the product I got from them. I would buy from them again and I have great confidence in them as a company and there products. Well priced and make putting in a shed base very easy. Very happy with the customer service I received and have a study shed base.

A good product that did everything we wanted.
Overall proved to be a solid and reliable base kit for a six by four foot platic Keter shed. We took no short cuts and removed turf, layered building sand then levelled the ground. The mesh supplied was then cut to size and placed over the levelled ground. The base grid was then placed on the prepared ground and the recesses filled and levelled with small white chipped stone. All good. Good value for money.

These are quite easy to lay and rock solid when filled with gravel
These come well packaged, and are quite easy to lay. The most time consuming part was popping the clips out of the sections, rather like taking the items off a sprue on a giant Airfix kit! Once filled with gravel it's a rock solid base. Like some other reviewers, this base was not quite the right size for our new Duramax (30214-1) 10 x 8 Feet V2 Wood Side Vinyl Shed. The base is 10" x 8'6", whereas the shed is about 10'6" x 8'. It was necessary to pack one side with gravel to extend the base, and we have 6" overhanging at the back of the shed, which isn't a problem. Fitting the clips is a bit tricky, since you can't get the clips under the sections if you are standing on them, but we found by angling the clips to get them over the sides of the two sections you are trying to join together, and then bringing the clips upright afterwards, that works. I definitely recommend the base, it's cheaper than using slabs and a lot of concrete and sand.

Great kit.
Easy to assemble once you've flattened the ground underneath. We put it where the old shed was when we moved in so the ground was already fairly flat. We used the weed membrane that came with it and held it together with the cable ties it came with, us extra to be sure. We filled it half with gravel, build the shed on top and have since done a nice gravel boarder leading to stepping stones to the shed. Looks great, wouldn't know it was there and when you walk in the shed it feels flat and sturdy. Should last for years! Will probably be there long after we move house, too. Definitely recommend- much easier than concreting or laying paving slabs in our experience. Our shed is 6x8 ft.

Use cable ties!
The service and communication from company was excellent. Predicted 3-4 days delivery and arrived next working day Quality is excellent, solid manufacturing and fault free. Didn’t like the clip design as left maybe 2 inch bit sticking down on every clip! This would need digging into ground and may compromise the weed suppressing ground sheet. NOT a problem, we simply cable tied them together instead and once filled with aggs it’s going nowhere and as solid as a concrete pour! Advice. We chose a 10mm gravel to infill and each panel took a 25kg bag per panel (maybe less if using a 20mm gravel as instructed) so took 30 bags to fill not a kg more or less! Perfect! Would highly recommend as a good foundation... we used ours for a log cabin and it’s solid as a rock!

Great alternative to concrete base
This plastic base is sturdy, easy to put together and a cheaper and more flexible alternative to a concrete base for a shed. The only thing I would improve are the clips which, if used, would puncture the very useful membrane provided. Instead, I followed some online advice to use plastic cable ties instead - much easier to use and keep the membrane intact.

Shed base
Excellent, but clips that hold the frame together are very difficult to attach and time consuming. Once completed very sturdy. 10 x 8 shed requires a minimum of 18 x 25kgs bags!

Bien mais peut mieux faire
Acheté ce kit pour servir de base à un abris de jardin en bois. Le produit vient d'Angleterre, le prix du port est justifié par le poids et l'encombrement de l'ensemble. Il comporte 9 dalles et un géotextile plastique. La durée d'acheminement est surestimée : commandé le jeudi soir, livré le mardi matin suivant, sachant que le numéro de suivi ne fonctionnait pas sur le site du transporteur (DPD d'abord, Chronopost ensuite). Le descriptif du produit est TRÈS mal fait, ce qui va coûter une étoile au produit ainsi que la méthode d'assemblage. Les dalles font 61 x 85 cm, elles sont extrêmement résistantes et sont sciables (à la scie à métaux) en deux dans le sens de la hauteur ou de la longueur. le kit de 9 dalles en 3x3 fait donc 255 x 183 cm au total. L'assemblage se fait par des sortes de pinces à linge fournies qu'on est censé enfoncer dans la terre à travers le géotextile. J'ai trouvé ce système absolument pas pratique ni résistant. J'ai donc assemblé les dalles entre elles avec des colliers serflex et enfoncé des sardines de tente dans le sol qui se trouvent noyées dans les cailloux utilisés pour le remplissage des grilles. A titre indicatif j'ai mis 230kgs de gravillons fins pour toute la surface. Au final, le rendu est esthétique (cet aspect dépend largement du matériau utilisé pour le remplissage) et très solide. Le mode d'emploi, en anglais, fourni donne une résistance de 100 tonnes au m², ce que je n'aurai bien sur jamais avec ma tondeuse dans mon abri de jardin....
