Find out moreThis self-levelling joist support system is perfect for levelling uneven floors and supporting roof decking. It is fully tested and conforms to the Loading Conditions for the Flooring as laid down in BS5399. Its unique design and buttress thread enable the cradle to carry high loads with finite adjustment to allow for accurate levelling of the floor/deck surface.
It is the ideal solution for supporting timber joists for decking purposes on balconies and roof terraces. The unique recycled plastic body is designed to support joists, keeping them off the roof deck and away from the roof drainage. The cradles can be adjusted to allow for the falls in the roof.
This cradle can also be used on uneven and out-of-level floors. The design enables the soft-sprung feel of a timber floor to be achieved over concrete sub-bases. It allows for fast installation and removes the need for wet and slow drying times typically associated with cementitious screeds. The void created by the cradle can also be insulated or used for service runs. The system is suitable for use in fast-track building programs or conservatory floors.
This cradle acts purely as a loading support, so care should be taken when loading the cradle to ensure that the sub-base can accept the load. The table of load centres is for a standard joist size. The load can be distributed by increasing the number of cradles.

50mm wide joists
Question:
Would this be suitable on grass
Answer:

Question:
Will 2"x2" timber work with these? At the lowest (10mm) rise will the top of the wood clear the plastic sides?
Answer:
A 2"x2" joist would not protrude over the top, for a joist this size you would need to use the lower rise cradle linked below.

Question:
Do you know the maximum fall this levels?
Answer:
This offers height adjustment from 10mm to 40mm so it could not adjust any fall greater than that i am afraid.
Question:
Hi, one answer above says these are suited to a 2" joist. My summerhouse joists are 60mm wide (2.36 inches). Are they too wide for this joist support?
Answer:
Yes they would not quite sit in the cradle I am afraid.
Question:
Hi could they be used to level a 5mx3.5m summer house under bearers?
Answer:
They could yes as long as it does not exceed their load capacity of 7 kN/m².
Question:
I'm renovating my Victorian property and looking to extend a suspended wooden floor with a crawl space through to an old wash house. The wash house floor is a solid stone floor so has no crawl space and is at the same level as what the joists from the adjoining room sit. My hope would be to use these joist cradles to support joists at a smaller depth to take out the difference in levels and maintain an air gap for ventilation so the floor could continue through. Would this be a suitable choice and do you know if it would be acceptable to building control? Loading would be max of 1.5Kn/m2
Answer:
This would certainly be suitable for creating a suspended floor definitey, with regards to building control always best to check with them first before making a purchase.
Question:
Hi would a 5 x2 drop into the slot ok . They are normally between 45mm and 47 mm Thankyou
Answer:
Yes these are suited to a 2" joist so would be fine.
Question:
can these be used to level a 6x4 shed on a patio.
Answer:
Yes you could use these for that purpose.
Question:
I’m looking to lay decking on top of my current stone patio. Can these be used on top of my patio? Do these fix to the concrete floor? If so, how? Many thanks.
Answer:
These can be used on top of your Patio no problem, they do not need to be fixed as the framework resting on them will hold them in place. You would also need to have a support per every 400mm length of timber.
