Our recommended method of construction is to use a Reclaimer/Recylcer/Milling Machine to mix the stabilizer and soil together in a homogenous mixture creating the 150mm layer and then using a grader to create the final levels and shaping followed by compaction. Once this layer has been constructed properly and the stabilizer given the required curing time a surface seal using the stabilizer is applied over the layer as a final seal. Upon completion of this the grassing can be done and during the hydro seeding of the edges the clear edge would be naturally defined as the seed will not germinate and root on in situ soil that is compacted to 98% Mod AASHTO.
In the absence of a Reclaimer a tractor pulled rotovator and a box blade may be used followed by a water tanker for the mixing of the copolymer and soil and finished as above.
