Sika Sika Greenstreak Speed Dowel Plus

The Sika Speed Dowel Plus 3/4″ Sleeve System is a patented round dowel load transfer solution built for slab-on-ground construction joints. Engineered for use with 3/4″ x 14″ smooth round dowels in slabs ranging 5″–6″ in depth, this system’s integrated sleeve and patented internal fins allow free lateral movement between concrete sections while eliminating harmful slab restraint. Compliant with ACI 302, ACI 330, and ACI 360 standards, it delivers the lateral movement capability of traditional plate dowel systems — at a fraction of the installation time and cost.

The one-piece design features preinstalled nails and built-in alignment marks for fast, accurate form attachment. No form drilling, greasing, spinning, or dowel removal is required, significantly reducing labor on the jobsite. Round dowels can also be sourced locally, helping cut freight costs compared to conventional plate doweling systems.

Key Features

The Speed Dowel Plus 3/4″ system is designed around a patented sleeve and fin configuration that allows free lateral movement between concrete slabs while maintaining positive load transfer — eliminating the slab restraint issues common with traditional doweling methods. The one-piece sleeve arrives with preinstalled nails and alignment marks already in place, meaning no form drilling, greasing, dowel spinning, or removal is required. This streamlines form setup considerably and improves the overall accuracy of dowel placement on the jobsite.

Compliant with ACI 302, ACI 330, and ACI 360 recommendations, this system meets the same performance standards as conventional plate dowel systems while offering a faster, more cost-effective installation process. Each carton contains 140 sleeves, making it well-suited for large-scale slab-on-ground projects where efficiency and consistency matter.

Frequently Asked Questions

Can the Speed Dowel Plus be used with epoxy-coated dowels? Yes, the system is fully compatible with smooth epoxy-coated dowels, making it a solid choice for corrosion-resistant applications such as parking structures and exterior slabs exposed to deicing chemicals.

How are the sleeves installed? Each sleeve is nailed directly to the wood form using the preinstalled nails, positioned either at mid-slab depth or 1-1/2″ down from the top of the slab. Once the first pour is complete and the form is stripped, the correctly sized round dowel is inserted into the sleeve slot, puncturing the tape seal and pushing through to the back of the sleeve.

What makes Speed Dowel Plus different from traditional dowel systems? Unlike conventional methods, the Speed Dowel Plus eliminates form drilling, greasing, spinning, and dowel removal entirely. Its patented sleeve and fin design provides the same lateral movement capability as a plate dowel system while using standard round dowels that can be sourced locally — reducing both labor time and freight costs.

What slab depths is the Speed Dowel Plus designed for? The system is available in multiple sleeve sizes to accommodate slab depths ranging from 5″ to 11″. Each sleeve size corresponds to a specific dowel dimension, ensuring proper alignment and load transfer for the intended slab thickness.

How many sleeves come in a carton? Each carton contains 140 sleeves, making it practical and efficient for large-scale slab-on-ground pours where consistent dowel placement across many joints is required.

Does the Speed Dowel Plus meet industry standards? Yes. The system is a compliant doweling method under ACI 302, ACI 330, and ACI 360, which govern concrete floor and slab construction, parking lot design, and slabs-on-ground respectively.
