- Base Stone - a pre-cast steel reinforced flat concrete stone (500 x 500 x 50mm tall) which connects to the underside of the Top Stone to spread the load of the building into more ground and to resist sideways movement.
- Ground Reinforcement Grid - (500 x 500 x 80mm) spreads the load into the ground and is made from 100% recycled plastic.

I needed to build a substantial outbuilding near protected trees, and found the ‘Swift’ system on the net. This seemed a good alternative to piling. On contacting them, it quickly became obvious they were ultra-attentive and helpful. On ordering the products, they arrived quickly and with no issues. The system is very cost effective, easy to use and does exactly what it says. Really excellent, and I have no hesitation in recommending this to a prospective purchaser. And I don’t usually feel comfortable recommending anything to anyone.

Neat and attractive solution. I’ve used these a couple of times now, and recommended to others.
Saves time and just what I needed on an uneven surface. Ecological because not wasting concrete on making a solid pad. Slight glitch with delivery that was ironed out promptly.

Martin was excellent with his help & advice. I needed to support an 18T cabin & these plinths were perfect for the job & were so easy to install saving time. They were delivered on a small pallet & on time so no chasing them which was good. I would definitely order these again & would highly recommend them.

We were recommended to use Swift plinths since they suited our sip build. We were worried that you would be able to see them and the house would look as if it were on stilts, but with paving slabs, rodent mesh and cladding, they were covered and now look nice. Our interaction with Martin from Swift Foundations was very good, quick and accommodating, and we had a good experience with Swift Foundations’ delivery service and can definitely recommend them if this is the sort of foundation you need.

I would and have been recommending Swift Foundations as not only is it a great product and easy to use and if like my project access is poor and all materials have to go through the house then this is the product to use. It negates the use of concrete, stone and damproofing issues and for these reasons I would also use this system on projects in situations where access is good. I chose this company over other similar companies as i found the sales staff friendly and their knowledge of the product was excellent.

I would recommend the Swift foundation system to others without hesitation. After a lot of research, it seems to be a good alternative to a more traditional concrete slab foundation but without a need to deal with a mess of concrete pouring. Order arrived quickly and without any problems. Martin was extremely helpful too, I felt comfortable checking any of my questions with him on the design and installation and he was extremely helpful. One more happy customer here.

I have built an extension under permitted rights using this system. These plinths made life much easier. They are very quick and inexpensive in comparison to regular footings or slab. I ordered and paid for them over the phone and took delivery 2 days later. if you are unsure as to what you will need, They are always ready to give advice.
I would recommend this system and especially this company to anyone considering a similar application as mine.
