Saves time & money
One person can install and no specialist tools are required
Fuel and Oil resistant so perfect for the petrochemical industry
Fully resistant to animal urine and silage effluent for agricultural uses
Manufactured in durable PVC which is 100% landfill diverted recycled material
Will never rot or rust and is non-conductive
Available in 3 metre rails in the UK, 8 feet rails in the USA and 2.8 metre in the rest of the world
No puncturing of DPM due to its innovative system of installation
Can be used with twin beams, Bunyan rollers & vibro strikes
No anchoring with metal stakes
Removable top strip so there is no need to wet diamond cut joints for sealant
Pour more concrete: Just set out your shuttering and pour bay after bay.
Patented design allows concrete to set without any need to use additional expansion joints.
24 mm holes pre-drilled at 300mm centres for dowel bars to suit various depths of concrete slabs
High quality levels and smooth slabs are achievable with a minimum of skilled labour
Virtually eliminates the need to order part loads of concrete to finish each pour
Drastically reduces pump hire expenditure as more concrete is placed each day
Spalled joints at intersections can be totally eliminated by offsetting the top strip to give straight joints.
Will K-Form tip over when the concrete is being poured?
No, the design of K-Form is such that the base of the profile is fully loaded in a downward direction before any lateral pressures are exerted onto the vertical section, thus ensuring stability whilst pouring
Does the top strip come out easily after the concrete has set?
Yes, the top strip is actually manufactured with a slight taper so that once it has moved it becomes loose and very easy to remove.
Does K-Form work as an expansion and contraction joint?
The vertical section of K-Form is designed to be compressible in much the same way as a fibre or foam joint fillers and in that sense, it will perform as an expansion joint. If the concrete goes into a contraction state, the smooth surface of the K-Form will naturally de bond from the concrete and allow it to pull away. Due to the many factors which affect what is required of an expansion joint, the function of K-Form as this joint is something that should be designed by the slab design engineer.
Will K-Form rot down in time?
K-Form is manufactured from recycled PVC window frames which have a huge lifespan which is in excess of 50 years. This means it will outperform fibre board joint fillers which actually have a very limited lifespan before they rot down.
Can K-Form withstand the load of the joint in a slab?
Within a concrete slab, K-Form merely performs as a joint filler and a level provider. The alternative is for a conventional joint which has fibre board or foam type joint fillers. All of these joint fillers (including K-Form) provide no integral strength to the slab in any way. The load bearing ability of a slab joint is purely provided by the dowel bar design which provide a load transfer capability across the joint.
What concrete slab thickness in K-Form designed for?
K35 - 50mm - 95mm slabs
K85 - 100mm-145mm slabs (the use of K25 extension strip may be required)
K135 - 150mm - 225mm slabs (the use of K25 extension strip may be required)
What is K-Form made from?
K-Form is made from 100% recycled UPVC sourced from landfill diverted used window frames.
