POLYvault™ is a modular design suitable for footway installations but is equally suited alongside rail tracks. The single wall design means the product remains very light even though it is a single piece construction.
Structural ribs on the outside provide resistance to vertical and sidewall loadings and this can be complemented with internal stiffening bars to accommodate higher specifications.
