All hard flooring moves independently by expanding and contracting at different rates so it is a requirement for flooring installations to have Movement Joint protection. Movement Joints are an effective way to protect ceramic and other hard floor coverings from the stresses that cause cracking, tenting or popping on the surface.

Clients generally do not like movement joints because it is felt that they can be obtrusive and spoil the aesthetic appearance of their carefully chosen floor. Specifiers and installers know that Movement Joints need to be used to absorb the natural movements in the floor. Architects are required to specify products that are fit for purpose and conform to building regulations and installers have a duty to provide good advice and workmanship. What ever your job title, our team of friendly and experienced staff are on hand to help guide you though the requirements of your projects.

British Standards 5385

Recommends that a movement joint should be able to absorb 20% of the width of the joint in movement accommodation. – Its actually 20% of the width of the infill.

Brass Profiles

Extruded angles from grade OT58 brass. Highly resistant to chemical attack and mechanical impact. Suitable for internal and external use.

Aluminium Profiles

Extruded angles from grade 6060 int aluminium. Suitable for internal use only and offers medium levels of edge protection from mechanical impact. This profile should not be used in harsh chemical environments.

Stainless Steel Profiles

Cold rolled profile manufactured from AIS1304 stainless steel. Recommended for use in food preparation areas, commercial kitchens, breweries and dairies etc. Also highly suitable for use in leisure environments including swimming pools (see below). For further information on the use of our Stainless Steel profiles, contact us.

Leisure Centre Changing Rooms / Swimming Pools

In dry areas of leisure facilities stainless steel grade V2 is adequate. In wet areas other than showers, for example in Swimming pool surrounds, we would recommend grade V4. The chemical composition of pool water can vary; it is always wise to provide these details in order that we can make a definitive recommendation.

Heated Floors

Over the last decade there has been a growth in the use of both electrical and wet system under floor heating and a parallel growth in the use of large format tiles has created a new set of problems for the installer. The first thing to remember is that the rapid expansion and contraction of the subfloor creates a very high level of stress, much higher than an unheated floor. Guidance from the British Standards has not kept up with the needs of the installer, The Tile Association however have been more forthcoming in recognizing that more guidance is needed. Essentially, guidelines are the same as a standard installation but with reduced field sizes. The TTA suggests that no field of tiling should exceed 40 squared meters with no one side exceeding 8 meters in length before a stress-relieving joint is installed.
