The Hawklok Pre-formed
Corner Summerhouse Base

Style and Design
The Hawlok is a modular garden building base system which is ideal for use with corner summerhouses.  It's strong, lightweight and easy to assemble and can readily be cut to shape with a handsaw.  The units are easily managed and laid and can be re-used or relocated in the event that you decide to move or replace your building. You can get a great idea of just exactly what's involved in installation of the system from the manufacturer's promotional video (opens in a new window).  Alternatively, take a look at the very straightforward printed instructions (opens in a new window).
The base modules are formed of rigid 100% recycled polypropylene.  They're black in colour and incorporate an interlocking feature secured by a locking peg for additional stability and to reduce the risk of movement, particularly during installation.
The individual units measure 600 x 600 x 45 mm and weigh in at 1.5 kg each.  Notional load capacity is up to 22 tonnes per square metre.  Units are supplied in various packs depending on your requirements.

Our Verdict
Although Hawkok tends to come in a little more expensive than some other modular base systems we think this is reflected in its undoubted quality.  The modules are a little larger than most other systems at 600 x 600mm and at 45mm The Hawklok gives you a little more depth than many others - although, granted, it doesn't outdo the 50mm provided by Taylor's Ecobase.  The extra millimetres will give a little extra drainage and may also help stability.

At up to 22 tonnes per square metre, the Hawklok's load bearing capacity should be sufficient for even the largest building - and according to the manufacturer there's no need to fill the units with gravel or any other medium either, though you might want to do this anyway, particularly with any visible parts of the foundation from the point of view of making them more visually attractive.  As a general principle, we'd advocate extending the base beyond the area of your summerhouse and filling the visible portion with pea gravel - and not only for aesthetic reasons.  Doing this will improve drainage around the building and reduce rainwater splashback onto the timbers which can be a significant cause of deterioration in some woodwork.

We don't really see any comparison between the Hawklok and more traditional solutions such as a wooden, paved or solid concrete foundation.  The Hawklok is far easier to install and potentially more durable than, for example, a wooden base which will be open to attack by the elements even if pressure treated.  There's simply far less work involved in laying Hawklok modules as opposed to, say, traditional concrete slabs - and when it comes you a solid concrete base you just need to take a look at the manufacturer's video (opens in a new window) to see the difference.  Granted, the video's produced by the manufacturer, but we think it makes the point quite well.

The modular units lock together well which should aid stability and in common with all plastic base systems the Hawklock can be cut to shape with a handsaw to match the footprint your building.  It's recycled polypropylene composition is environmentally friendly too

All in all, we think the Hawklok is ideally suited to larger, heavier buildings.  There's certainly no reason why you shouldn't use it for a smaller building, but you might find a cheaper option if you look through our list of pre-formed base systems which would serve you just as well.  We can't find any real issues with the Hawklok - so five stars.
