K-Form Screed Rail is out of this world! It’s so easy to put down, it does two jobs at once, and we could not get the work done as fast as we do without K-Form. I don’t know of any other concrete form out there that does what K-Form does. Alan Bullen - Commercial DeveloperA.B. Developments, Cambridgeshire, United Kingdom

K-Form - Straight and level every timeSave time and money using K-Form

K-Form set up to be used as: a form, screed rail, and control/expansion joint at the same time

”Victory Bear is proud to introduce K-FORM North America

Proven by a decade of use in the United Kingdom, K-FORM is an all-in-one screed rail and concrete forming system.

Simple to use, K-FORM saves time and labor costs by allowing you to pour more concrete per day and fi nish the job faster.

K-FORM outperforms steel and wood formwork in most aspects of application, and can be used in many locations (such as gas stations) where steel or wood formwork cannot.

The K-FORM PVC form system provides the construction

industry with an economical, effi cient and environmentally

friendly alternative to wood and steel forms.

Made from recycled materials, K-FORM is lightweight, durable,

and does not require removal after concrete pouring. It is

easily cut to length on site, and has pre-drilled holes in the

vertical face for installing dowel bars, and in the base for

mortar anchoring.

Once the contractor uses K-Form, he keeps coming back for more. The product sells itself! Andy Simms - Business ManagerBurdens (Civil Engineering products / Building Materials) Plymouth, Devon, United Kingdom

We can pour concrete continuously, without spending time stripping formwork, and setting up again. K-Form saved us thousands in labor costs. The job turns out brilliant using a new, true form every time. It would be safe to say, we would never go back to steel forms again.

Pervious Concrete Applications:


Testimonial:

While consulting on the Washington, DC, Pervious “Green Alley” pilot program, we had the opportunity to incorporate K-Form into the pavement design in place of a cork expansion joint material that was typically used. On one particular alley that had three diff erent widths, we were not slowed down at all during the concrete placement trying to get the joint right. K-Form was easily cut to size and leveled using a string level to bring it to the fi nished elevation. Unlike wood forms that present an issue with pervious concrete falling when you remove the forms, K-Form allowed us to leave the form in place, off ering a much better-looking and structurally stronger pavement. We were so impressed with K-Form that we incorporated it into our pervious specifi cations immediately after the Washington, DC job.

With K-FORM you can pour more concrete:

Just set out your K-Form and pour bay

after bay.

With K-FORM’s removable Void Cap there

is no need to diamond cut joints for

sealant.

K-FORM’s patented design allows concrete

to set without any need to use additional

expansion joints.

This is an authoritative document proving the fi tness for the purpose of a construction product and its compliance or contribution to compliance with the various building regulations applying in the United Kingdom. It is commonly referred to as a ‘BBA Agreement Certifi cate’.

K-FORM is ideal for concrete slabs of various thicknesses. The rail is simply laid on a lean mix or mortar bed to the required fi nished height:

1. Set up your string line.

2. Cut the fi rst Void Cap in half, attach to the fi rst rail and fi t Joint Clips.

3. Place spots of bedding mortar on the sub-base at intervals of 32” to correspond with holes in the base.

4. Place the rail on the bed and gently tap down with a rubber mallet until the top of the Void Cap is at the desired level.

5. Place bedding for the next rail as in Step 3.

6. Join the second rail to the fi rst with the Joint Clips.

7. Fit the full length of the Void Cap across rails.

8. Tap down the rail as in Step 4.

9. Each 8 foot K-FORM rail has pre drilled 7/8” holes for dowels.

10. Once the bedding mortar has cured, you can start pouring concrete.

11. K-FORM rails stay in place, therefore adjoining bays can be poured one after the other.

12. Once the concrete has cured, the Void Cap can either be left in place or removed. If removing, the gap can subsequently be fi lled with a joint sealant.
