Soft Joints In Floors

[Wishiwasatoptiler]

Thanks for the replys , unfortunately the builder thinks he knows everything and has set all the expansion joints in the floor there's no bay bigger than 30m2 in fairness to him just won't use matting or 'expensive ' preformed stripes.
The floor is a hotel entrance /bar/eating area = 300m2 the rest are kitchens/ toilets ect so nowhere should have anything other than foot traffic .
Would anyone have a bs on soft joints I could show him if it needs to be 6mm or over might even sway him to the strips !!
Thanks again for your replies

think the idea of no tollies in kitchens is wrong. Take it from me, porters will rack trollies to breaking point and then trash them till the wheels are shot. Then delivery drivers will wheel in gages over six foot high and they will be filled to busted with beers, wines and cans. There will be a ton of weight on four wheels all day long. After spend 20 years in hotels and kitchens I know. Hope that info helps.

Dural do a New Micro Joint its the same width as you grout joints, You just use a sealant gun and fill it in after, They will colour match any colour grout, I have used this Micro Joint & they matched Kerakoll Limestone Fugalite grout, It worked great !!

Have you got a web link for this product 😉

BS 5385-4 advises that stresses may develop within the tiling system as a result of movements due to such factors as drying shrinkage and moisture movements in the background and thermal and moisture changes in the tiling. These stresses, if not properly controlled, can be sufficient to cause loss of adhesion and bulging or cracking of the tiling, sometimes with dramatic effect.

4.2 Sealant Movement Joints

4.2.1 Types of joint

There are two basic types of movement joints in floors, structural or non-structural joints and non-structural or non structural joints. A structural joint passes through the tile, screed and floor slab. A non structural joint passes through the tile and screed only and does not penetrate the floor slab

Movement at a structural joint is brought about by structural movement of the building and may be caused by thermal changes, producing both expansion and contraction, or by permanent shrinkage of the building causing opening and closing of the joint but is not cyclic. Non structural joints are used to allow shrinkage of the floor slab relative to the tiles. Non structural joints are made in the covering to allow the differential movement to occur without damage to the tiles; the principal movement being the closing of the joint with only minimal thermal movement. Structural and non structural joints are subject to different movement patterns that influence the choice of sealant types.


The filler or backing material immediately below the sealant should be compatible with the sealant being used. It should be compressible and should support the sealant. It needs to be of a material type that the sealant will not adhere to. Such materials include closed cell foam polyethylene and appropriate closed cell rubber where additional support is required. Where there is insufficient joint depth to accommodate a joint backing material and the required sealant depth polyethylene bond breaker tape may be used.

And a pic for you .... All direct from bs...

in kitchens of restaurants tile should be at least 12 mm thickness . no?

Looks like a great product for large domestic floors. Using it next month. Will post how I get on with it. It's what I thought you used in the stone job I commented on Julian
