There are several critical aspects to a hybrid turf surface. Two that stand out are:
The projected use of the field / venue. As hybrid turf surfaces are vulnerable to the build-up of thatch, the top layer must be cleaned and cleared regularly. That is why most owners subject the field to rigorous maintenance every summer break before sowing new grass. As a consequence, the field will not be available during the summer period to host events or concerts, meaning that recouping the investment by hosting events during the summer break is hardly possible.
The construction of the top layer. Injected hybrid surfaces and lay-and-play solutions both require a lean construction that does not facilitate the growth of microorganisms in the soil. A hybrid turf surface, where the soil is reinforced with small plastic fibres to provide a stable surface, does require a soil that facilitates the presence and growth of natural organisms to stimulate grass growth.
