Composite Profiled Foundation Beams.  These are made from recycled plastic and will never EVER rot.
Suitable for any make of log cabin and are superior to every other style of beam as water will always be drawn away from the important first log.  The profiled beams will extend the life of any manufacturer's log cabin and are Unique to Tuindeco.
Foundation beams are essential for any log cabin to ensure untreated wood is not placed directly onto the ground. Whilst all Tuin log cabins are supplied with pressure treated foundation beams as standard, these beams include a 'profile' to allow water to drain away from the base of any building.
40.2070 - For log Thicknesses 19, 28 and 34mm - 3.5cm x 8.8cm x300cm
40.2071 - For log Thicknesses 44, 45, 58 and 70mm - 3.5cm x 8.8cm x 300cm (change in profile)
Each beam will need to be cut to size upon installation and installed end to end. The log cabin base will need to be made slightly larger than the footprint of the cabin when these are used.

In my mind these are mandatory and unique to Tuin. Easy to use and will prevent moisture damage to the base of the cabin.

These beams were well worth the extra cost over the equivalent wood beams. They were easy to cut to size with a first cut saw. The slope directs water away from bottom edge of bottom plank.

Overall I am pleased that I upgraded to these foundation beams, simply due to the peace of mind in knowing they'll never rot. However, they did present a few challenges at build time that I hadn't anticipated. First and foremost beware if your cabin has a door frame that sits on the foundation beam (instead of the bottom half-log). You'll need to remove the "upstand" (lip) somehow, which is far from easy. I decided to plane mine off which was hard-going but manageable until I encountered metal splinters embedded in the plastic. In hindsight a saw would probably have been better... on which point this material is very difficult to hand-saw. I'd estimate 5 x the cutting time of an equivalent cross-section of wood, which adds up when you're hand-mitring 6 x corners. I didn't bother with a secondary DPC beneath the beam (because it's plastic after all), but you do need a separate sealant between base and beam. I had a nice smooth float finished concrete base, but the surface contact wicks any water ingress into gaps along the perimeter. A capillary groove would be a good solution the manufacturer might consider (mentioned by someone below), but that would only help if you've been really precise with your base dimensions. A generous bead of sealant did the trick for me.

Beams lack a capillary groove to underside! Had to have one routed in to avoid water creeping pack to cabin platform that beams were set on. Cannot understand why not used as best building practice dictate this for window and door cills. Otherwise worth the extra over basic wood beam.

This is the second time I've used these on a workshop build, this time using them between a concrete base and CLS timber frame. They are an excellent way of isolating the timber from moisture, highly recommended.
