SELFLEVEL® Concrete Access Assembly

The concrete SELFLEVEL® Access Assembly has been designed specifically for concrete applications. By incorporating adjustment brackets into the design, the frame can be held up during the concrete installation. This product is ideal for environments with frost heave, as the frame floats with the surface.

Improved Ride Quality

Once installed, the unit will continue to move with the road surface. The road surface aids in absorption of traffic vibration and shock, further protecting the life of your infrastructure and critical underground structures. SELFLEVEL has a range of motion of up to a 5° tip angle while still moving with the surface. This design helps eliminate frost heave/uplift, manhole structure settling, site deterioration, and pavement cracking. It also provides improved ride quality to meet smooth street initiatives.

The “Floating” Effect

The multi-functional seal helps keep the upper frame centered within the guide frame, which prevents the two pieces from touching. The seal protects against excess debris and material from entering the manhole.

The guide frame facilitates self-centering and keeps the upper frame centered over the manhole structure, and the upper frame is supported by and moves with the surrounding road surface. This allows it to remain level with the road surface. This “floating” effect helps prevent road damage and protects the infrastructure underground by dispersing traffic vibrations and shock throughout the road surface, rather than into the structure below.

Concrete Application Features

A steel sleeve creates a void while pouring concrete to allow the upper frame to float with the road surface. The adjustment bracket and bolt for raising the upper frame up off the lower frame during pouring gives it clearance to "float" when set in concrete. After the concrete cures, the bracket and bolt are removed and can be reused. Adjustment bolt tabs can be cut off for greater clear opening after installation.
