ProBASE GRIDS Shed Base Foundation Kit *SPECIAL OFFER*
PROBASE GRIDS: ULTRA STRONG plastic shed base grid foundation is the only grid system on the market designed to carry a vertical load such as a garden building without the need to fill the grids with gravel. ProBase grids are independently tested when per square metre, empty at over 200 tonnes of vertical load making it easy for the DIY novice to achieve a professional quality shed base for your garden building. ProBASE GRID shed base are the strongest plastic grid base system made in the UK, and carry a manufacturers 25-year guarantee.
BEWARE OF OTHER GRID SYSTEMS: All other grids on the market are gravel retention systems, not shed bases (despite being advertised as such). At first glance, they appear to be the same, however they act in a completely different way. Gravel retention systems are not strong, instead they need to be filled with gravel to give it strength, and it is this gravel that gives them strength. Cheaper gravel retention grids are designed to sit on top of 6" of a compacted type-1 hardcore sub-base, because they don’t have any load spreading feet. In comparison, ProBASE has proper load-spreading feet, and is designed to sit down straight onto your compacted ground without purchasing additional materials.
WHY IS PROBASE SO MUCH BETTER?: ProBASE connects laterally with secure locking pins at two points along each side making the joint strong and durable. ProBase grids measure 500mm x 500mm at room temperature (unlike other manufacturers grids which tend to measure 495mm x 495mm) and ProBASE grids don’t contract by 3% in cold weather like many other grids. ProBase has UV filters included in the high quality plastic to prevent the plastic from becoming brittle when exposed to sunshine. ProBase is manufactured in the UK to ISO 9001, and the plastic is a certified high quality blend, sourced from a reputable supplier with strict control over the ingredients and regularly tested for its quality. ProBase is strong, needing no additional gravel or hardcore, and it is supplied with a top-quality, non-woven, commercially graded geo-textile membrane, and is UV-resistant and rot-resistant. ProBASE are completely reusable, maintenance-free, very light, easy to handle, and cost a fraction of the price of a traditional concrete base. To create your perfect shed base, simply join as many ProBASE grid tiles together as required to make a base foundation of ANY SIZE. If required, ProBASE tiles can be easily cut to any shape using a normal hand saw.
We recommend that ProBASE grids are fitted as a full base, however you can remove some tiles for a cost saving if preferred (Option-2).

Each UK manufactured ProBASE grid is
Quality Construction VERY, VERY STRONG in fact it is 50% THICKER** and TWICE AS STRONG as most competitors and therefore needs no filling out with gravel or soil for small or standard sheds. They are made from the highest quality, UV stabilized, 100% recycled plastic, and each grid measures approximately 500mm x 500mm x 40mm weighing just 1.25kg each, however thanks to it's patented design it has a huge crush rating which can withstand 87 tonnes per grid (or 350 TONNES M²) when filled with pea shingle... so just to put that into perspective... each grid is strong enough to take the weight of 16x AFRICAN BULL ELEPHANTS standing on top of each other... in other words they will easily take the weight of ANY GARDEN BUILDING.
*Average Cell Wall Thickness Comparison - ProBase40 (4.85mm) Vs EcoBase45 (3.2mm). Probase is 50% thicker (Tested 01/05/2015)
The answer is simple...
Why Choose ProBASE? STRENGTH. However if you are considering going for another brand, you should also ask your supplier the following questions:
Where are the grids actually manufactured?
Where is the plastic material sourced and is it certified?
How are the grids tested, with gravel in them or empty?
Can you see a copy of their test certificate?
Does the plastic have any UV filters in it?
What are the contraction percentages?
ProBASE will save you money over 'cheaper' brands, because you don't need to purchase any fillers, gravel or hardcore. The plastic used on each ProBASE grid is thicker and more rigid than any other plastic grid on the market today, and the Secure-Lock joining system is more robust. Some manufacturers have similar sized shed base grids (500mm x 500mm), but their cell walls tend to be taller and much thinner, allowing the base to twist. The cell walls on the ProBASE are 50% thicker than the next best product, thus providing a stronger. more rigid tile. Other manufacturers produce a much smaller 330mm tile (i.e. 9 tiles per sq.metre) which flexes at each joint. ProBASE are much larger (only 4 tiles per sq. metre), therefore the integrity of the overall base is much higher. Also, larger grids can be fitted in less than half the time... which is a real bonus! ProBASE grids are made from the highest quality, 100% recycled, 100% recyclable plastic, and are are designed to last a lifetime, and can be lifted and reused as often as required.

Each ProBASE grid (including the locking pins) is made from 100% recycled plastic, and requires
No Maintenance or preservative. These tiles are are designed to last a lifetime, and have a NO MAINTENANCE 25-year manufacturers warranty!
The ProBASE is very easy to assemble. Simply prepare a level area (the ProBASE system can be laid directly onto grass, soil, builders sand or pea gravel), then lay out your membrane, cut to size if necessary, lay the ProBASE tiles on top of the membrane then lock together using supplied pegs. A sub-base guide is available to
Straight-forward Assembly download.
We recommend that the ProBASE grids are joined together to make a complete base. This is the strongest and easiest way to create your shed base. If you are trying to keep costs down as low as possible, then you can leave some spaces underneath your floor. It takes more planning as you have to ensure that your bearers are still being supported, however it can save you a fair amount of money, especially if it's a large base. We call this set-up Option-2. You can

No Professional Assembly The ProBASE has been designed to allow the novice to create a high quality, strong, long-lasting shed base without the need for a expensive professional service.
ProBASE is great for traditional wooden sheds, summerhouses, cabins or any building which has an integral floor, but because of its open cell construction, it isn't really suitable as a base for metal sheds or greenhouses (or any other building without a
Exceptions floor). It can be used as a walkway or as secondary flooring INSIDE these buildings, however it will not be supporting the walls. Please give us a call prior to ordering if you are unsure.
Optional Extras There are no optional extras are available for the ProBASE, however it does come with a ground membrane which will be cut to match the size of your building (please state size when ordering). ProBASE tiles are very strong, and for small or medium bases, therefore don't need to be filled with gravel. However you may want to fill any visible external areas with pea shingle to make it look nice, and reduce the amount of water splash back from the roof. Normally it takes 10kg of pea gravel to fill a tile, and you should be able to purchase this from your local building supply company.
Please contact us prior to purchase if you have any queries regarding the dimensions, or if you require exact sizes.

Reviewer: Jean Rose from Bristol
Arrived promptly and when they said it would. Got to work at 1.30pm, finished by 2.15pm! Base was already prepared but even so. Very impressed. Very easy. Recommended.
Reviewer: Stephen Bingham from Peterborough
A absolute fantastic product will recommend to others easy to construct and lightweight to handle better than slabs and more hardy I should think. Satisfied customer

Reviewer: Frederick Craft from Smallford, Herts
Requested delivery within 24 hours and they did. ProBase and service was first class. Will use them again with confidence.
Many thanks to A1 sheds.
Reviewer: William Dunn from Blackburn, Bathgate
The ProBASE was easy to lay and the instructions very good. Compared to
having a concrete slab laid it was as good, but at a fraction of the cost.
The key is is in the preparation and having a level surface to lay the grid.
Once again, many thanks.
Reviewer: Richard from Dorking, Surrey
Very impressed with the Probase product and especially impressed with the speedy delivery. Ordered Probase on a Tuesday am and on arriving home on the Wednesday pm product was on the front door. Very easy to assemble and laid in rough position in less than 30 minutes.
Reviewer: B. Holmes from York
I initially tried to purchase the original 6/12pin ecobase system, but it has now been discontinued and is unavailable. I must say that I am glad that I went for this new probase with 2/4 pins as I fould it easier and faster to fit. I would recommend it.
Reviewer: Peter Hough from South Molton
PERFECT, PERFECT, PERFECT. In fact I would award 6 stars if I could. They were delivered AND installed within 24 hours of ordering. The tiles are more than strong enough for my shed, yet were light and easy to handle. I cannot find fault with either the product or the service, I just wish that this would happen more often when purchasing online. Thank you, I will purchase from you again.
Reviewer: Trevor Hall from Dundee
Good product which was easy to fit and my shed is sitting nicely now but I wanted delivery next day and they took 2 days to come so I have only given 4 stars. I would buy again.
Reviewer: Carters Paving & Hard Landscaping from East Linton
used the old ecobases before but they always seemed to be from different batches as some were green and others were black. the sizes werent regular either so they soemtimes wanted to twist. the new probases arent as heavy but they made a much better job on the ground. the plastic is better and they were all the same size and colour. the lock pegs are better so they were quicker and easier to lay and do a good job. customer was delighted.. Calum
Reviewer: James Baron from Sunderland
Fast and easy. Good item.
Reviewer: P Duncan from Jersey
I needed a light shed base that I could send to the Channel Isles, and I had intended to go for Ecobase tiles as I had used them before, but your customer service team suggested the Probase units as they were even lighter. I must say that I cannot fault them, they are better made than the Ecobase tiles (which I was happy with before), and the locking pins are better. Thank you. Peter Duncan
Reviewer: G. Simpson from Stirling
I had no problem installing the Probase tiles. The product is well made, and I would definitely buy them again. Service was fast. No complaints.
